ITEM 1. BUSINESS

Overview

Spirit Airlines is an ultra low-cost, low-fare airline based in Miramar, Florida that offers affordable travel to price-conscious customers. Our all-Airbus fleet currently operates more than 200 daily flights to over 50 destinations in the United States, Caribbean and Latin America. We completed an initial public offering during the second quarter of 2011, and our stock trades on the NASDAQ Global Select Stock Market under the symbol "SAVE".

Our ultra low-cost carrier, or ULCC, business model allows us to compete principally through offering low base fares and charging separately for select optional services, thereby allowing customers the freedom to save by choosing only the extras they value. We have unbundled components of our air travel service that have traditionally been included in base fares, such as baggage and advance seat selection, and offer them as optional, ancillary services (which we record in our financial statements as non-ticket revenue) as part of a strategy to enable our passengers to identify, select and pay only for the services they want to use.

Our History and Corporate Information

We were founded in 1964 as Clippert Trucking Company, a Michigan corporation. We began air charter operations in 1990 and renamed ourselves Spirit Airlines, Inc. in 1992. In 1994, we reincorporated in Delaware, and in 1999 we relocated our headquarters to Miramar, Florida. On June 1, 2011, we completed our initial public offering of common stock. For more information, see "Notes to Financial Statements- 18. Initial Public Offering and Tax Receivable Agreement".

Our mailing address and executive offices are located at 2800 Executive Way, Miramar, Florida 33025, and our telephone number at that address is (954) 447-7920. We are subject to the information and periodic reporting requirements of the Securities Exchange Act of 1934, or Exchange Act, and, in accordance therewith, file periodic reports, proxy statements and other information with the Securities and Exchange Commission, or SEC. Such periodic reports, proxy statements and other information are available for inspection and copying at the SEC's Public Reference Room at 100 F Street, NE., Washington,

DC 20549 or may be obtained by calling the SEC at 1-800-SEC-0330. In addition, the SEC maintains a Web site at http://www.sec.gov that contains reports, proxy statements and other information regarding issuers that file electronically with the SEC. We also post on the Investor Relations page of our Web site, www.spirit.com, a link to our filings with the SEC, our Corporate Governance Guidelines and Code of Business Conduct and Ethics, which applies to all directors and all our employees, and the charters of our Audit, Compensation, Finance and Nominating and Corporate Governance committees. Our filings with the SEC are posted as soon as reasonably practical after they are filed electronically with the SEC. Please note that information contained on our Web site is not incorporated by reference in, or considered to be a part of, this report.

Our Business Model

Our ULCC business model provides customers very low base fares with a range of optional services, allowing customers the freedom to choose only the extras they value. The success of our model is driven by our low cost structure, which permits us to offer very low base fares while maintaining one of the highest profit margins in the industry.

We are focused on price-sensitive travelers who pay for their own travel, and our business model is designed to deliver what we believe our customers want: low fares. We aggressively use low fares to stimulate air travel demand in order to increase passenger volume, load factors and non-ticket revenue on the flights we operate. Higher passenger volumes and load factors help us sell more ancillary products and services, which in turn allows us to reduce the base fare we offer even further, stimulating additional demand. We strive to be recognized by our customers and potential customers as the low-fare leader in the markets we serve.

We compete based on total price. We believe other airlines have used an all-inclusive price concept to effectively raise total prices to consumers, rather than lowering fares by unbundling each product or service. For example, carriers that tout “free bags” have included the cost of checking bags in the total ticket price, not allowing passengers to see how much they would save if they did not check luggage. We believe that we and our customers benefit when we allow our customers to know the total price of their travel by breaking out the cost of additional, optional products or services. Before they pay, our customers are easily able to compare the total cost of flying with us versus flying with another airline.

We allow our customers to see all available options and their prices prior to purchasing a ticket, and this full transparency illustrates that our total prices are lower, on average, than our competitors, even when options are included.

Our Strengths

We believe we compete successfully in the airline industry by leveraging the following demonstrated business strengths:

Ultra-Low Cost Structure. Our unit operating costs are among the lowest of all airlines operating in the Americas. We believe this cost advantage helps protect our market position and enables us to offer some of the lowest base fares in our markets, sustain among the highest operating margins in our industry, and support continued growth. Our operating costs per available seat mile (CASM) of 10.09 cents in 2012, are significantly lower than those of the major domestic network carriers, American Airlines, Delta Air Lines, United Air Lines and US Airways, and among the lowest of the domestic low-cost carriers, including JetBlue Airways and Southwest Airlines. We achieve these low unit operating costs in large part due to:


•	high aircraft utilization;


•	high-density seating configurations on our aircraft;


•	our simple operations;


•	no hub-and-spoke inefficiencies ;


•	highly productive workforce;


•	opportunistic outsourcing of operating functions;


•	operating a modern single fleet type of Airbus A320-family aircraft, with associated lower maintenance costs and common flight crews across the fleet;


•	reduced sales, marketing and distribution costs through direct-to-consumer marketing;


•	efficient flight scheduling, including minimal ground times between flights; and


•	a company-wide business culture that is keenly focused on driving costs lower.

Innovative Revenue Generation. We execute our innovative, unbundled pricing strategy to produce significant non-ticket revenue generation, which allows us to stimulate passenger demand for our product by lowering base fares and enabling passengers to identify, select, and pay for the products and services they want to use. Our unbundled strategy has enabled us to grow average non-ticket revenue per passenger flight segment from approximately $5 in 2006 to $51 in 2012 by:


•	charging for checked and carry-on baggage;


•	passing through all distribution-related expenses;


•	charging for premium seats and advance seat selection;


•	enforcing ticketing policies, including service charges for changes and cancellations;


•	generating subscription revenue from our $9 Fare Club ultra low-fare subscription service;


•	deriving brand-based revenues from proprietary services, such as our FREE SPIRIT affinity credit card program;


•	selling itinerary attachments, such as hotel and car rental reservations and travel insurance, through our website; and


•	selling in-flight products and onboard advertising.

Resilient Business Model and Customer Base. By focusing on price-sensitive travelers, we have maintained relatively stable unit revenue and profitability during volatile economic periods because we are not highly dependent on premium-fare business traffic. We believe our growing customer base is more resilient than the customer bases of most other airlines because our low fares and unbundled service offering appeal to price-sensitive passengers. For example, in 2009, when premium-fare business traffic dried up due to the economic recession, our operating revenue per available seat mile (RASM) declined 1.9%, compared to an average U.S. airline industry decline of over 9%.

Well Positioned for Growth. We have developed a substantial network of destinations in profitable U.S. domestic niche markets, targeted growth markets in the Caribbean and Latin America, and high-volume routes flown by price-sensitive travelers. In the United States, we also have grown into large markets that, due to higher fares, have priced out those more price-sensitive travelers. Our strategy to balance growth in large domestic markets, niche markets and opportunities in the Caribbean and Latin America gives us a significant number of growth opportunities.

Experienced International Operator. We believe we have substantial experience in foreign local aviation, security and customs regulations, local ground operations and flight crew training required for successful international and overwater flight operations. All of our aircraft are certified for overwater operations. We believe we compete favorably against other low-cost carriers because we have been conducting international flight operations since 2003 and have developed substantial experience in complying with the various regulations and business practices in the international markets we serve.

Financial Strength Achieved by Cost Discipline Focus. We believe our ULCC business model has delivered strong financial results in difficult economic times. We have generated these results by:


•	keeping a consistent focus on maintaining low unit operating costs;


•	maintaining disciplined capacity control and fleet size;


•	ensuring our sourcing arrangements with key third parties are continually benchmarked against the best industry standards;


•	maintaining a simple operation that focuses on delivering transportation; and


•	generating and maintaining an adequate level of liquidity to insulate against volatility in key cost inputs, such as fuel, and in passenger demand that may occur as a result of changing general economic conditions.

Route Network

As of December 31, 2012, our route network included 110 markets served by 52 airports throughout North America, Central America, South America and the Caribbean.

Below is a route map of our current network, which includes seasonal routes and routes announced as of January 31, 2013 for which service has not yet started:

Our network expansion targets underserved and/or overpriced markets. We utilize a rigorous process to identify growth opportunities to deploy new aircraft where we believe they will be profitable. To monitor the profitability of each route, we analyze weekly and monthly profitability reports as well as near term forecasting.

Competition

The airline industry is highly competitive. The principal competitive factors in the airline industry are fare pricing, total price, flight schedules, aircraft type, passenger amenities, number of routes served from a city, customer service, safety record and reputation, code-sharing relationships, and frequent flier programs and redemption opportunities. Our competitors and potential competitors include traditional network airlines, low-cost carriers, and regional airlines. We typically compete in markets served by traditional network airlines and other low-cost carriers, and, to a lesser extent, regional airlines.

Our single largest overlap, at approximately 60% of our markets as of January 8, 2013, is with American Airlines. Our principal competitors on domestic routes are American Airlines, Southwest Airlines, United Airlines, and Delta Airlines. Our principal competitors for service from South Florida to our markets in the Caribbean and Latin America are American Airlines through its hub in Miami and JetBlue Airways through its operations in Fort Lauderdale. Our principal competitive advantages are our low base fares and our focus on the price-sensitive traveler who pays his or her own travel costs. These low base fares are facilitated by our low unit operating costs, which in 2012 were among the lowest in the industry. We believe our low costs coupled with our non-ticket revenues allow us to price our fares at levels where we can be profitable while our primary competitors cannot.

The airline industry is particularly susceptible to price discounting because, once a flight is scheduled, airlines incur only nominal incremental costs to provide service to passengers occupying otherwise unsold seats. The expenses of a scheduled aircraft flight do not vary significantly with the number of passengers carried and, as a result, a relatively small change in the number of passengers or in pricing could have a disproportionate effect on an airline’s operating and financial results. Price competition occurs on a market-by-market basis through price discounts, changes in pricing structures, fare matching, target promotions and frequent flier initiatives. Airlines typically use discount fares and other promotions to stimulate traffic during normally slower travel periods to generate cash flow and to maximize RASM. The prevalence of discount fares can be particularly acute when a competitor has excess capacity that it is under financial pressure to sell. A key element to our competitive strategy is to maintain very low unit costs in order to permit us to compete successfully in price-sensitive markets.

Seasonality

Our business is subject to significant seasonal fluctuations. We generally expect demand to be greater in the second and third quarters compared to the rest of the year. The air transportation business is also volatile and highly affected by economic cycles and trends.

Distribution

The majority of our tickets are sold through direct channels including online via www.spirit.com, our call center and the ticket counter with spirit.com being the primary channel. We also partner with a number of third parties to distribute our tickets, including online and traditional travel agents and electronic global distribution systems.

Customers

The majority of our customers travel for leisure (non-business) purposes, and leisure travel is discretionary and tends to be more price sensitive. By focusing on lowering our cost structure, we can successfully sell tickets at low fares while maintaining a strong profit margin.

Customer Service

We are committed to taking care of our customers. We believe focus on customer service in every aspect of our operations including personnel, flight equipment, in-flight and ancillary amenities, on-time performance, flight completion ratios, and baggage handling will strengthen customer loyalty and attract new customers. We proactively aim to improve our operations to ensure further improvement in customer service.

In response to customer and other demands, we recently modified our online booking process to allow our customers to see all available options and their prices prior to purchasing a ticket, and have initiated a campaign that illustrates our total prices are lower, on average, than our competitors, even when options are included.

Fleet

We fly only Airbus A320 family aircraft, which provides us significant operational and cost advantages compared to airlines that operate multiple aircraft types. By operating a single aircraft type, we avoid the incremental costs of training crews across multiple types. Flight crews are entirely interchangeable across all of our aircraft, and maintenance, spare parts inventories and other operational support remains highly simplified compared to those of more complex fleets. Due to this commonality among Airbus single-aisle aircraft, we can retain the benefits of a fleet comprised of a single type of aircraft while still having the flexibility to match the capacity and range of the aircraft to the demands of each route.

As of December 31, 2012, we had a fleet of 45 Airbus single-aisle aircraft, consisting of 27 A319s, 16 A320s and two A321s, and the average age of the fleet was 4.6 years. All of our existing aircraft were financed under operating leases.

As of December 31, 2012, firm aircraft orders with Airbus and a third party consisted of 106 A320 family aircraft (two used A319 aircraft, 54 of the existing A320 aircraft model, and 50 A320 NEOs). Aircraft are scheduled for delivery from 2013 through 2021. We also have a contractual purchase commitment for three spare V2500 IAE International Aero Engines AG engines scheduled for delivery from 2013 through 2015. The aircraft provide for growth capacity as well as give us flexibility in our fleet plan to replace all or some of the 31 aircraft in our present fleet with lease expirations between 2016 and 2020. We may elect to supplement these deliveries by additional acquisitions from the manufacturer or in the open market if demand conditions merit.

Consistent with our ULCC business model, each of our aircraft is configured with a high density seating configuration. Our A319s accommodate 145 passengers (compared to 120 on United and 124 on US Airways), our A320s accommodate 178 passengers (compared to 138 or 144 on United and 150 on JetBlue and US Airways) and our A321s accommodate 218 passengers (compared to 183 on US Airways).

Maintenance and Repairs

We have an FAA mandated and approved maintenance program, which is administered by our technical services department. Our maintenance technicians undergo extensive initial and ongoing training to ensure the safety of our aircraft.

Aircraft maintenance and repair consists of routine and non-routine maintenance and work performed is divided into three general categories: line maintenance, heavy maintenance and component service. Line maintenance consists of routine daily and weekly scheduled maintenance checks on our aircraft, including pre-flight, daily, weekly and overnight checks and

any diagnostics and routine repairs and any unscheduled items on an as needed basis. Line maintenance events are currently serviced by in-house mechanics supplemented by contract labor and are primarily completed at airports we currently serve. Heavy airframe maintenance checks consist of a series of more complex tasks that can take from one to four weeks to accomplish and typically are required approximately every 20 months. Heavy engine maintenance is performed approximately every four to six years and includes a more complex scope of work. Due to our relatively small fleet size and projected fleet growth, we believe outsourcing all of our heavy maintenance activity, such as engine servicing, major part repair and component service repairs is more economical. Outsourcing eliminates the substantial initial capital requirements inherent in heavy aircraft maintenance. We have entered into a long-term flight hour agreement with IAE for our engine overhaul services and Lufthansa Technik on an hour-by-hour basis for component services. We outsource our heavy airframe maintenance to FAA-qualified maintenance providers.

Our recent maintenance expenses have been lower than what we expect to incur in the future because of the relatively young age of our aircraft fleet. Our maintenance costs are expected to increase as the scope of repairs increases with the increasing age of our fleet. As our aircraft age, scheduled scope of work and frequency of unscheduled maintenance events is likely to increase like any mature fleet. Our aircraft utilization rate could decrease with the increase in aircraft maintenance.

Employees

Our business is labor intensive, with labor costs representing approximately 19.1%, 19.6% and 22.0% of our total operating costs for 2012, 2011 and 2010, respectively. As of December 31, 2012, we had 680 pilots, 933 flight attendants, 24 flight dispatchers, 269 mechanics, 795 airport agents/other, and 332 employees in administrative roles for a total of 3,033 employees. Approximately 54% of our employees were represented by labor unions under three different collective-bargaining agreements. On an average full-time equivalent basis, for the full year 2012, we had 2,767 employees, compared to 2,456 in 2011.

FAA regulations require pilots to have commercial licenses with specific ratings for the aircraft to be flown, and to be medically certified as physically fit to fly. FAA and medical certifications are subject to periodic renewal requirements including recurrent training and recent flying experience. In December 2007, federal legislation was enacted increasing the mandatory retirement age for U.S. commercial airline pilots from age 60 to age 65. Mechanics, quality-control inspectors, and flight dispatchers must be certificated and qualified for specific aircraft. Flight attendants must have initial and periodic competency training and qualification. Training programs are subject to approval and monitoring by the FAA. Management personnel directly involved in the supervision of flight operations, training, maintenance, and aircraft inspection must also meet experience standards prescribed by FAA regulations. All safety-sensitive employees are subject to pre-employment, random, and post-accident drug testing.

The Railway Labor Act, or RLA, governs our relations with labor organizations. Under the RLA, the collective bargaining agreements generally do not expire, but instead become amendable as of a stated date. If either party wishes to modify the terms of any such agreement, they must notify the other party in the manner agreed to by the parties. Under the RLA, after receipt of such notice, the parties must meet for direct negotiations, and if no agreement is reached, either party may request the National Mediation Board, or NMB, to appoint a federal mediator. The RLA prescribes no set timetable for the direct negotiation and mediation process. It is not unusual for those processes to last for many months, and even for a few years. If no agreement is reached in mediation, the NMB in its discretion may declare at some time that an impasse exists, and if an impasse is declared, the NMB proffers binding arbitration to the parties. Either party may decline to submit to arbitration. If arbitration is rejected by either party, a 30-day “cooling off” period commences. During that period (or after), a Presidential Emergency Board, or PEB, may be established, which examines the parties’ positions and recommends a solution. The PEB process lasts for 30 days and is followed by another “cooling off” period of 30 days. At the end of a “cooling off” period, unless an agreement is reached or action is taken by Congress, the labor organization and the airline each may resort to “self-help,” including, for the labor organization, a strike or other labor action, and for the airline, the imposition of any or all of its proposed amendments and the hiring of new employees to replace any striking workers. Congress and the President have the authority to prevent “self-help” by enacting legislation that, among other things, imposes a settlement on the parties. The table below sets forth our employee groups and status of the collective bargaining agreements.



Employee Groups	Representative	Amendable Date
Pilots	Air Line Pilots Association, International (ALPA)	August 2015
Flight Attendants	Association of Flight Attendants (AFA-CWA)	August 2007
Dispatchers	Transport Workers Union (TWU)	July 2012

We focus on hiring highly productive employees and, where feasible, designing systems and processes around automation and outsourcing in order to maintain our low cost base.

Safety and Security

We are committed to the safety and security of our passengers and employees. We strive to comply with or exceed health and safety regulation standards. In pursuing these goals, we maintain an active aviation safety program and all of our personnel are expected to participate in the program and take an active role in the identification, reduction, and elimination of hazards.

Our ongoing focus on safety relies on training our employees to proper standards and providing them with the tools and equipment they require so they can perform their job functions in a safe and efficient manner. Safety in the workplace targets several areas of our operation including: flight operations, maintenance, in-flight, dispatch, and station operations. The Transportation Security Administration, or TSA, is charged with aviation security for both airlines and airports. We maintain active, open lines of communication with the TSA at all of our locations to ensure proper standards for security of our personnel, customers, equipment and facilities are exercised throughout the operation.

Insurance

We maintain insurance policies we believe are customary in the airline industry and as required by the DOT. The policies principally provide liability coverage for public and passenger injury; damage to property; loss of or damage to flight equipment; fire and extended coverage; directors’ and officers’ liability; advertiser and media liability; cyber risk liability; fiduciary; and workers’ compensation and employer’s liability. We have obtained third-party war risk (terrorism) insurance through a special program administered by the FAA, resulting in lower premiums than if we had obtained this insurance in the commercial insurance market. Should the government discontinue this coverage, obtaining comparable coverage from commercial underwriters could result in substantially higher premiums and more restrictive terms, if it is available at all. Although we currently believe our insurance coverage is adequate, there can be no assurance that the amount of such coverage will not be changed or that we will not be forced to bear substantial losses from accidents.

Foreign Ownership

Under DOT regulations and federal law, we must be controlled by U.S. citizens. In order to qualify, at least 75% of our stock must be voted by U.S. citizens, and our president and at least two-thirds of our board of directors and senior management must be U.S. citizens.

On December 7, 2011, we entered into a Stock Distribution Agreement with Indigo Miramar LLC and its members. Pursuant to the Stock Distribution Agreement 10,576,180 shares of outstanding common stock were exchanged on a share-for-share basis for shares of non-voting common stock. As of February 11, 2013, we had no non-voting shares outstanding due to the conversion of all non-voting shares to voting shares in compliance with the Stock Distribution Agreement.

Government Regulation

Operational Regulation

The airline industry is heavily regulated, especially by the federal government. Two of the primary regulatory authorities overseeing air transportation in the United States are the DOT and the FAA. The DOT has jurisdiction over economic issues affecting air transportation, such as competition, route authorizations, advertising and sales practices, baggage liability and disabled passenger transportation, among other areas, several of which were included in new rules that became effective in 2011 and 2012 relating to, among other things, how airlines handle interactions with passengers through advertising, the reservation process, at the airport and on board the aircraft. The DOT has extended the effective date for certain of these rules. See “Risk Factors—Restrictions on or increased taxes applicable to charges for ancillary products and services paid by airline passengers and burdensome consumer protection regulations or laws could harm our business, results of operations and financial condition.” The DOT has a pending notice of proposed rulemaking addressing additional accommodations required for passengers with certain disabilities among other matters.

The DOT has authority to issue certificates of public convenience and necessity required for airlines to provide air transportation. We hold a DOT certificate of public convenience and necessity authorizing us to engage in scheduled air transportation of passengers, property, and mail within the United States, its territories and possessions and between the United States and all countries that maintain a liberal aviation trade relationship with the United States (known as “open skies” countries). We also hold DOT certificates to engage in air transportation to certain other countries with more restrictive aviation policies.

The FAA is responsible for regulating and overseeing matters relating to air carrier flight operations, including airline operating certificates, aircraft certification and maintenance and other matters affecting air safety. The FAA requires each commercial airline to obtain and hold an FAA air carrier certificate. This certificate, in combination with operations specifications issued to the airline by the FAA, authorizes the airline to operate at specific airports using aircraft approved by

the FAA. As of December 31, 2012, we had FAA airworthiness certificates for all of our aircraft, we had obtained the necessary FAA authority to fly to all of the cities we currently serve and all of our aircraft had been certified for overwater operations. We believe we hold all necessary operating and airworthiness authorizations, certificates and licenses and are operating in compliance with applicable DOT and FAA regulations, interpretations and policies.

International Regulation

All international service is subject to the regulatory requirements of the foreign government involved. We currently operate international service to Aruba, the Bahamas, Colombia, Costa Rica, Dominican Republic, El Salvador, Guatemala, Haiti, Honduras, Jamaica, Mexico, Nicaragua, Panama, Peru and St. Maarten, as well as Puerto Rico and the U.S. Virgin Islands. If we decide to increase our routes to additional international destinations, we will be required to obtain necessary authority from the DOT and the applicable foreign government. We are also required to comply with overfly regulations in countries that lay along our routes but which we do not serve.

International service is also subject to Customs and Border Protection, or CBP, immigration and agriculture requirements, and the requirements of equivalent foreign governmental agencies. Like other airlines flying international routes, from time to time we may be subject to civil fines and penalties imposed by CBP if unmanifested or illegal cargo, such as illegal narcotics, is found on our aircraft. These fines and penalties, which in the case of narcotics are based upon the retail value of the seizure, may be substantial. We have implemented a comprehensive security program at our airports to reduce the risk of illegal cargo being placed on our aircraft, and we seek to cooperate actively with CBP and other U.S. and foreign law enforcement agencies in investigating incidents or attempts to introduce illegal cargo.

Security Regulation

The TSA was created in 2001 with the responsibility and authority to oversee the implementation, and ensure the adequacy, of security measures at airports and other transportation facilities. Funding for passenger security is provided in part by a per enplanement ticket tax (passenger security fee) of $2.50 per passenger flight segment, subject to a $5 per one-way trip cap. The TSA was granted authority to impose additional fees on air carriers if necessary to cover additional federal aviation security costs. Pursuant to its authority, the TSA may revise the way it assesses this fee, which could result in increased costs for passengers and us. We cannot forecast what additional security and safety requirements may be imposed in the future or the costs or revenue impact that would be associated with complying with such requirements. The TSA also assesses an Aviation Security Infrastructure Fee, or ASIF, on each airline. Our ASIF fee is approximately $1.6 million per year.

Environmental Regulation

We are subject to various federal, state and local laws and regulations relating to the protection of the environment and affecting matters such as aircraft engine emissions, aircraft noise emissions, and the discharge or disposal of materials and chemicals, which laws and regulations are administered by numerous state and federal agencies. The Environmental Protection Agency, or EPA, regulates operations, including air carrier operations, which affect the quality of air in the United States. We believe the aircraft in our fleet meet all emission standards issued by the EPA. Concern about climate change and greenhouse gases may result in additional regulation or taxation of aircraft emissions in the United States and abroad.

Federal law recognizes the right of airport operators with special noise problems to implement local noise abatement procedures so long as those procedures do not interfere unreasonably with interstate and foreign commerce and the national air transportation system. These restrictions can include limiting nighttime operations, directing specific aircraft operational procedures during takeoff and initial climb, and limiting the overall number of flights at an airport. None of the airports we serve currently restricts the number of flights or hours of operation, although it is possible one or more of such airports may do so in the future with or without advance notice.

Other Regulations

We are subject to certain provisions of the Communications Act of 1934, as amended, and are required to obtain an aeronautical radio license from the Federal Communications Commission, or FCC. To the extent we are subject to FCC requirements, we will take all necessary steps to comply with those requirements. We are also subject to state and local laws and regulations at locations where we operate and the regulations of various local authorities that operate the airports we serve.

Future Regulations

The U.S. and foreign governments may consider and adopt new laws, regulations, interpretations and policies regarding a wide variety of matters that could directly or indirectly affect our results of operations. We cannot predict what laws, regulations, interpretations and policies might be considered in the future, nor can we judge what impact, if any, the implementation of any of these proposals or changes might have on our business.

ITEM 1A. RISK FACTORS

You should carefully consider the risks described below and the other information in this report. If any of the following risks materialize, our business could be materially harmed, and our financial condition and results of operations could be materially and adversely affected. The risks described below are not the only ones facing us. Additional risks not currently known to us or that we currently believe are immaterial may also impair our business, results of operations, financial condition and liquidity.

Risks Related to Our Industry

We operate in an extremely competitive industry.

We face significant competition with respect to routes, fares and services. Within the airline industry, we compete with traditional network airlines, other low-cost airlines and regional airlines on many of our routes. Competition in most of the destinations we presently serve is intense, due to the large number of carriers in those markets. Furthermore, other airlines may begin service or increase existing service on routes where we currently face no or little competition. Substantially all of our competitors are larger and have significantly greater financial and other resources than we do.

The airline industry is particularly susceptible to price discounting because once a flight is scheduled, airlines incur only nominal additional costs to provide service to passengers occupying otherwise unsold seats. Increased fare or other price competition could adversely affect our operations. Moreover, many other airlines have begun to unbundle services by charging separately for services such as baggage and advance seat selection. This unbundling and other cost reducing measures could enable competitor airlines to reduce fares on routes that we serve.

In addition, airlines increase or decrease capacity in markets based on perceived profitability. Decisions by our competitors that increase overall industry capacity, or capacity dedicated to a particular domestic or foreign region, market or route, could have a material adverse impact on our business. If a traditional network airline were to successfully develop a low-cost structure or if we were to experience increased competition from other low-cost carriers, our business could be materially adversely affected.

All of the domestic traditional network airlines have on one or more occasions initiated bankruptcy proceedings in attempts to restructure their debt and other obligations and reduce their operating costs. On November 29, 2011, AMR Corporation and substantially all of its subsidiaries, including American Airlines, Inc., filed a petition for relief under Chapter 11 of the U.S. Bankruptcy Code. We presently compete with American Airlines in a majority of our markets. We cannot predict the extent to which the pendency of this bankruptcy proceeding will change our competitive dynamic with American Airlines or the extent to which a successfully reorganized American Airlines, or the acquisition of American Airlines by another carrier, will result in a more effective competitor to us.

Our growth and the success of our ULCC business model could stimulate competition in our markets through our competitors’ development of their own ULCC strategies or new market entrants. Any such competitor may have greater financial resources and access to cheaper sources of capital than we do, which could enable them to operate their business with a lower cost structure than we can. If these competitors adopt and successfully execute a ULCC business model, we could be materially adversely affected.

There have been numerous mergers and acquisitions within the airline industry including, for example, the recent combinations of Delta Air Lines and Northwest Airlines, United Airlines and Continental Airlines, and Southwest Airlines and AirTran Airways. In the future, there may be additional mergers and acquisitions in our industry. Any business combination could significantly alter industry conditions and competition within the airline industry and could cause fares of our competitors to be reduced.

The extremely competitive nature of the airline industry could prevent us from attaining the level of passenger traffic or maintaining the level of fares or revenues related to ancillary services required to sustain profitable operations in new and existing markets and could impede our growth strategy, which could harm our operating results. Due to our relatively small size, we are susceptible to a fare war or other competitive activities in one or more of the markets we serve, which could have a material adverse effect on our business, results of operations, and financial condition.

Our low cost structure is one of our primary competitive advantages, and many factors could affect our ability to control our costs.

Our low cost structure is one of our primary competitive advantages. However, we have limited control over many of our costs. For example, we have limited control over the price and availability of aircraft fuel, aviation insurance, airport and

related infrastructure taxes, the cost of meeting changing regulatory requirements, and our cost to access capital or financing. In addition, the compensation and benefit costs applicable to a significant portion of our employees are established by the terms of our collective bargaining agreements. We cannot guarantee we will be able to maintain a cost advantage over our competitors. If our cost structure increases and we are no longer able to maintain a cost advantage over our competitors, it could have a material adverse effect on our business, results of operations and financial condition.

The airline industry is heavily impacted by the price and availability of aircraft fuel. Continued volatility in fuel costs or significant disruptions in the supply of fuel, including hurricanes and other events affecting the Gulf Coast in particular, could materially adversely affect our business, results of operations, and financial condition.

Aircraft fuel costs represent our single largest operating cost, accounting for 41.2%, 41.9%, and 34.8% of our total operating expenses for 2012, 2011 and 2010, respectively. As such, our operating results are significantly affected by changes in the availability and the cost of aircraft fuel, especially aircraft fuel refined in the U.S. Gulf Coast region, on which we are highly dependent. Both the cost and the availability of aircraft fuel are subject to many meteorological, economic, and political factors and events occurring throughout the world, which we can neither control nor accurately predict. For example, a major hurricane making landfall along the Gulf Coast could cause disruption to oil production, refinery operations, and pipeline capacity in that region, possibly resulting in significant increases in the price of aircraft fuel and diminished availability of aircraft fuel supplies. Any disruption to oil production, refinery operations, or pipeline capacity in the Gulf Coast region could have a disproportionate impact on our operating results compared to other airlines that have more diversified fuel sources.

Aircraft fuel prices have been subject to high volatility, fluctuating substantially over the past several years. Due to the large proportion of aircraft fuel costs in our total operating cost base, even a relatively small increase in the price of aircraft fuel can have a significant negative impact on our operating costs and on our business, results of operations and financial condition.

Our fuel hedging strategy may not reduce our fuel costs.

We enter into fuel derivative contracts in order to mitigate the risk to our business from future volatility in fuel prices. As of December 31, 2012, we had fuel hedges using U.S. Gulf Coast jet fuel collars in place for approximately 5% of our 2013 anticipated fuel consumption. Additionally, during peak hurricane season (August through October), we may enter into jet fuel swaps to protect the refining price risk between the price of crude oil and the price of refined jet fuel. There can be no assurance that we will be able to enter into fuel hedge contracts in the future. Our liquidity and general level of capital resources impacts our ability to hedge our fuel requirements. Even if we are able to hedge portions of our future fuel requirements, we cannot guarantee that our hedge contracts will provide sufficient protection against increased fuel costs or that our counterparties will be able to perform under our hedge contracts, such as in the case of a counterparty’s insolvency. Furthermore, our ability to react to the cost of fuel, absent hedging, is limited because we set the price of tickets in advance of incurring fuel costs. Our ability to pass on any significant increases in aircraft fuel costs through fare increases could also be limited. Finally, it is currently unknown what impact the Dodd-Frank Wall Street Reform and Consumer Protection Act will have on collateral and margin requirements for fuel hedging, which could significantly impair our ability to hedge our fuel costs. As of December 31, 2012, the fair value of our fuel derivative contracts was an asset of $0.3 million. In the event of a reduction in fuel prices compared to our hedged position, our hedged positions could counteract the cost benefit of lower fuel prices and could require us to post additional cash margin collateral. Please see “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Trends and Uncertainties Affecting Our Business—Aircraft Fuel.”

Restrictions on or increased taxes applicable to charges for ancillary products and services paid by airline passengers and burdensome consumer protection regulations or laws could harm our business, results of operations, and financial condition.

During 2012, 2011 and 2010, we generated non-ticket revenues of $535.6 million, $381.5 million and $243.3 million, respectively. Our non-ticket revenues are generated from charges for, among other things, baggage, bookings through our distribution channels, advance seat selection, itinerary changes and loyalty programs. In April 2011, the DOT published a broad set of final rules relating to, among other things, how airlines handle interactions with passengers through advertising, the reservations process, at the airport and on board the aircraft. The final rules require airlines to publish a full fare for a flight, including mandatory taxes and fees, and to enhance disclosure of the cost of optional products and services, including baggage charges. The rules restrict airlines from increasing ticket prices post-purchase (other than increases resulting from changes in government-imposed fees or taxes) or increase significantly the amount and scope of compensation payable to passengers involuntarily denied boarding due to oversales. The final rules also extend the applicability of tarmac delay reporting and penalties to include international flights and provide that reservations made more than one week prior to flight date may be held at the quoted fare without payment, or cancelled without penalty, for 24 hours. All of these new rules became effective by January 24, 2012. If we are not able to remain in compliance with these rules, the DOT may subject us to fines or other enforcement action, including requirements to modify our passenger reservations system, which could have a material adverse

effect on our business. Moreover, we cannot assure you that compliance with these rules will not have a material adverse effect on our business. In addition, the U.S. Congress and Federal administrative agencies have investigated the increasingly common airline industry practice of unbundling the pricing of certain products and services. If new taxes are imposed on non-ticket revenues, or if other laws or regulations are adopted that make unbundling of airline products and services impermissible, or more cumbersome or expensive, our business, results of operations, and financial condition could be harmed. Congressional and other government scrutiny may also change industry practice or public willingness to pay for ancillary services. See also “—We are subject to extensive regulation by the Federal Aviation Administration, the Department of Transportation, and other U.S. and foreign governmental agencies, compliance with which could cause us to incur increased costs and adversely affect our business and financial results.”

The airline industry is particularly sensitive to changes in economic conditions. Continued adverse economic conditions or a reoccurrence of such conditions would negatively impact our business, results of operations and financial condition.

Our business and the airline industry in general are affected by many changing economic conditions beyond our control, including, among others:


•	changes and volatility in general economic conditions, including the severity and duration of any downturn in the U.S. or global economy and financial markets;


•	changes in consumer preferences, perceptions, spending patterns or demographic trends, including any increased preference for higher-fare carriers offering higher amenity levels, and reduced preferences for low-fare carriers offering more basic transportation, during better economic times;


•	higher levels of unemployment and varying levels of disposable or discretionary income;


•	depressed housing and stock market prices; and


•	lower levels of actual or perceived consumer confidence.

These factors can adversely affect, and from time to time have adversely affected, our results of operations, our ability to obtain financing on acceptable terms and our liquidity. Unfavorable general economic conditions, such as higher unemployment rates, a constrained credit market, housing-related pressures and increased focus on reducing business operating costs can reduce spending for price-sensitive leisure and business travel. For many travelers, in particular the price-sensitive travelers we serve, air transportation is a discretionary purchase that they may reduce or eliminate from their spending in difficult economic times. The overall decrease in demand for air transportation in the United States in 2008 and 2009 resulting from record high fuel prices and the economic recession required that we take significant steps to reduce our capacity, which reduced our revenues. Unfavorable economic conditions could also affect our ability to raise prices to counteract increased fuel, labor or other costs, resulting in a material adverse effect on our business, results of operations, and financial condition.

The airline industry faces ongoing security concerns and related cost burdens, further threatened or actual terrorist attacks, or other hostilities that could significantly harm our industry and our business.

The terrorist attacks of September 11, 2001 and their aftermath negatively affected the airline industry. The primary effects experienced by the airline industry included:


•	substantial loss of revenue and flight disruption costs caused by the grounding of all commercial air traffic in or headed to the United States by the Federal Aviation Administration, or FAA, for about three days after the terrorist attacks;


•	increased security and insurance costs;


•	increased concerns about future terrorist attacks;


•	airport shutdowns and flight cancellations and delays due to security breaches and perceived safety threats; and


•	significantly reduced passenger traffic and yields due to the subsequent dramatic drop in demand for air travel.

Since September 11, 2001, the Department of Homeland Security and the Transportation Security Administration, or TSA, have implemented numerous security measures that restrict airline operations and increase costs, and are likely to implement additional measures in the future. For example, following the widely publicized attempt of an alleged terrorist to detonate plastic explosives hidden underneath his clothes on a Northwest Airlines flight on Christmas Day in 2009, passengers became subject to enhanced random screening, which may include pat-downs, explosive detection testing or body scans. Enhanced passenger screening, increased regulation governing carry-on baggage and other similar restrictions on passenger

travel may further increase passenger inconvenience and reduce the demand for air travel. In addition, increased or enhanced security measures have tended to result in higher governmental fees imposed on airlines, resulting in higher operating costs for airlines, which we may not be able to pass on to consumers in the form of higher prices. Any future terrorist attacks or attempted attacks, even if not made directly on the airline industry, or the fear of such attacks or other hostilities (including elevated national threat warnings or selective cancellation or redirection of flights due to terror threats) would likely have a material adverse effect on our business, results of operations and financial condition, and on the airline industry in general.

Airlines are often affected by factors beyond their control including: air traffic congestion at airports; air traffic control inefficiencies; adverse weather conditions, such as hurricanes or blizzards; increased security measures; new travel related taxes or the outbreak of disease, any of which could harm our business, operating results, and financial condition.

Like other airlines, we are subject to delays caused by factors beyond our control, including air traffic congestion at airports, air traffic control inefficiencies, adverse weather conditions, increased security measures, new travel related taxes and the outbreak of disease. Delays frustrate passengers and increase costs, which in turn could adversely affect profitability. The federal government singularly controls all U.S. airspace, and airlines are completely dependent on the FAA to operate that airspace in a safe, efficient, and affordable manner. The air traffic control system, which is operated by the FAA, faces challenges in managing the growing demand for U.S. air travel. U.S. and foreign air-traffic controllers often rely on outdated technologies that routinely overwhelm the system and compel airlines to fly inefficient, indirect routes resulting in delays. Adverse weather conditions and natural disasters, such as hurricanes affecting southern Florida and the Caribbean as well as other areas of the eastern United States (such as Hurricane Sandy in October 2012), winter snowstorms or the January 2010 earthquakes in Port-au-Prince, Haiti, can cause flight cancellations or significant delays. Cancellations or delays due to adverse weather conditions or natural disasters, air traffic control problems or inefficiencies, breaches in security or other factors could harm our business, results of operations and financial condition. Similarly, outbreaks of pandemic or contagious diseases, such as avian flu, severe acute respiratory syndrome (SARS) and H1N1 (swine) flu, could result in significant decreases in passenger traffic and the imposition of government restrictions in service and could have a material adverse impact on the airline industry. Increased travel taxes, such as those provided in the Travel Promotion Act, enacted March 10, 2010, which charges visitors from certain countries a $10 fee every two years to travel into the United States to subsidize certain travel promotion efforts, could also result in decreases in passenger traffic. Any general reduction in airline passenger traffic could have a material adverse effect on our business, results of operations and financial condition.

Restrictions on or litigation regarding third-party membership discount programs could harm our business, operating results and financial condition.

We generate a relatively small but growing portion of our revenue from order referral fees, revenue share and other fees paid to us by third-party merchants for customer click-throughs, distribution of third-party promotional materials and referrals arising from products and services of the third-party merchants that we offer to our customers on our website. Some of these third-party referral-based offers are for memberships in discount programs or similar promotions made to customers who have purchased products from us, and for which we receive a payment from the third-party merchants for every customer that accepts the promotion. Certain of these third-party membership discount programs have been the subject of consumer complaints, litigation and regulatory actions alleging that the enrollment and billing practices involved in the programs violate various consumer protection laws or are otherwise deceptive. Any private or governmental claim or action that may be brought against us in the future relating to these third-party membership programs could result in our being obligated to pay damages or incurring legal fees in defending claims. These damages and fees could be disproportionate to the revenues we generate through these relationships. In addition, customer dissatisfaction or a significant reduction in or termination of the third-party membership discount offers on our website as a result of these claims could have a negative impact on our brand, and have a material adverse effect on our business, results of operations and financial condition.

We face competition from air travel substitutes.

In addition to airline competition from traditional network airlines, other low-cost airlines and regional airlines, we also face competition from air travel substitutes. On our domestic routes, we face competition from some other transportation alternatives, such as bus, train or automobile. In addition, technology advancements may limit the demand for air travel. For example, video teleconferencing and other methods of electronic communication may reduce the need for in-person communication and add a new dimension of competition to the industry as travelers seek lower-cost substitutes for air travel. If we are unable to adjust rapidly in the event the basis of competition in our markets changes, it could have a material adverse effect on our business, results of operations and financial condition.

Risks Related to Our Business

Increased labor costs, union disputes, employee strikes and other labor-related disruption may adversely affect our business, results of operations and financial conditions.

Our business is labor intensive, with labor costs representing approximately 19.1%, 19.6% and 22.0% of our total operating costs for 2012, 2011 and 2010, respectively. As of December 31, 2012, approximately 54% of our workforce was represented by labor unions and thereby covered by collective bargaining agreements. We cannot assure you that our labor costs going forward will remain competitive because in the future our labor agreements may be amended or become amendable and new agreements could have terms with higher labor costs; one or more of our competitors may significantly reduce their labor costs, thereby reducing or eliminating our comparative advantages as to one or more of such competitors; or our labor costs may increase in connection with our growth. We may also become subject to additional collective bargaining agreements in the future as non-unionized workers may unionize.

Relations between air carriers and labor unions in the United States are governed by the Railway Labor Act, or the RLA. Under the RLA, collective bargaining agreements generally contain “amendable dates” rather than expiration dates, and the RLA requires that a carrier maintain the existing terms and conditions of employment following the amendable date through a multi-stage and usually lengthy series of bargaining processes overseen by the National Mediation Board, or the NMB. This process continues until either the parties have reached agreement on a new collective bargaining agreement, or the parties have been released to “self-help” by the NMB. In most circumstances, the RLA prohibits strikes; however, after release by the NMB, carriers and unions are free to engage in self-help measures such as lockouts and strikes.

Our flight operations were shut down due to a strike by our pilots beginning on June 12, 2010 and lasting until we and the union representing our pilots reached a tentative agreement for a new contract. Under a Return to Work Agreement, we began to resume flights on June 17, 2010 and resumed our full flight schedule on June 18, 2010. On August 1, 2010, we and the pilots’ union executed a five-year collective bargaining agreement. This shutdown had a material adverse effect on our results of operations for 2010. Please see “Management’s Discussion and Analysis of Financial Condition and Results of Operations—June 2010 Pilot Strike.”

Our collective bargaining agreement with our flight attendants became amendable in August 2007, and we are currently engaged in negotiations with the union representing our flight attendants. Our collective bargaining agreement with our dispatchers became amendable in July 2012. The outcome of our pending collective bargaining negotiations cannot presently be determined and the terms and conditions of our future collective bargaining agreements may be affected by the results of collective bargaining negotiations at other airlines that may have a greater ability, due to larger scale, greater efficiency or other factors, to bear higher costs than we can. In addition, if we are unable to reach agreement with any of our unionized work groups in current or future negotiations regarding the terms of their collective bargaining agreements, we may be subject to work interruptions or stoppages. Any such action or other labor dispute with unionized employees could disrupt our operations, reduce our profitability, or interfere with the ability of our management to focus on executing our business strategies. Our business, results of operations and financial condition may be materially adversely affected based on the outcome of our negotiations with the union representing our flight attendants.

We have a significant amount of aircraft-related fixed obligations that could impair our liquidity and thereby harm our business, results of operations and financial condition.

The airline business is capital intensive and, as a result, many airline companies are highly leveraged. All of our aircraft are leased, and in 2012 and 2011 we paid the lessors rent of $140.8 million and $116.6 million, respectively, and maintenance deposits net of reimbursements of $31.6 million and $36.8 million, respectively. As of December 31, 2012, we had future operating lease obligations of approximately $1.2 billion. In addition, we have significant obligations for aircraft and spare engines that that we have ordered from Airbus and International Aero Engines AG, or IAE, (or any other engine manufacturer for future deliveries) for delivery over the next nine years. Our ability to pay the fixed costs associated with our contractual obligations will depend on our operating performance, cash flow, and our ability to secure adequate financing, which will in turn depend on, among other things, the success of our current business strategy, whether fuel prices continue at current price levels and/or further increase or decrease, further weakening or improving in the U.S. economy, as well as general economic and political conditions and other factors that are, to some extent, beyond our control. The amount of our aircraft related fixed obligations could have a material adverse effect on our business, results of operations and financial condition and could:


•	require a substantial portion of cash flow from operations for operating lease and maintenance deposit payments, thereby reducing the availability of our cash flow to fund working capital, capital expenditures and other general corporate purposes;


•	limit our ability to make required pre-delivery deposit payment, or PDPs, including those payable to Airbus or IAE for our aircraft and spare engines on order;


•	limit our ability to obtain additional financing to support our expansion plans and for working capital and other purposes on acceptable terms or at all;


•	make it more difficult for us to pay our other obligations as they become due during adverse general economic and market industry conditions because any related decrease in revenues could cause us to not have sufficient cash flows from operations to make our scheduled payments;


•	reduce our flexibility in planning for, or reacting to, changes in our business and the airline industry and, consequently, place us at a competitive disadvantage to our competitors with less fixed payment obligations; and


•	cause us to lose access to one or more aircraft and forfeit our rent deposits if we are unable to make our required aircraft lease rental payments and our lessors exercise their remedies under the lease agreement including cross default provisions in certain of our leases.

A failure to pay our operating lease and other fixed cost obligations or a breach of our contractual obligations could result in a variety of adverse consequences, including the exercise of remedies by our creditors and lessors. In such a situation, it is unlikely that we would be able to cure our breach, fulfill our obligations, make required lease payments or otherwise cover our fixed costs, which would have a material adverse effect on our business, results of operations and financial condition.

We are highly dependent upon our cash balances and operating cash flows.

As of December 31, 2012, we had access to lines of credit from two counterparties to our jet fuel derivatives and our purchase credit card issuer aggregating $36.6 million. These credit facilities are not adequate to finance our operations, and we will continue to be dependent on our operating cash flows and cash balances to fund our operations and to make scheduled payments on our aircraft related fixed obligations. Although our credit card processors currently do not have a right to hold back credit card receipts to cover repayment to customers, if we fail to maintain certain liquidity and other financial covenants, their rights to holdback would be reinstated, which would result in a reduction of unrestricted cash that could be material. In addition, we are required by some of our aircraft lessors to fund reserves in cash in advance for scheduled maintenance, and a portion of our cash is therefore unavailable until after we have completed the scheduled maintenance in accordance with the terms of the operating leases. Based on the age of our fleet and our growth strategy, these maintenance deposits will increase over the next few years before we receive any significant reimbursement for completed maintenance. If we fail to generate sufficient funds from operations to meet our operating cash requirements or do not obtain a line of credit, other borrowing facility or equity financing, we could default on our operating lease and fixed obligations. Our inability to meet our obligations as they become due would have a material adverse effect on our business, results of operations, and financial condition.

A deterioration in worldwide economic conditions may adversely affect our business, operating results, financial condition, liquidity and ability to obtain financing or access capital markets.

The general worldwide economy has experienced a downturn due to the effects of the European debt crisis, unfavorable U.S. economic conditions and slowing growth in certain Asian economies, including general credit market crises, collateral effects on the finance and banking industries, concerns about inflation, slower economic activity, decreased consumer confidence, reduced corporate profits and capital spending, adverse business conditions and liquidity concerns. The airline industry is particularly sensitive to changes in economic conditions, which affect customer travel patterns and related revenues. A weak economy could reduce our bookings, and a reduction in discretionary spending could also decrease amounts our customers are willing to pay. Unfavorable economic conditions can also impact the ability of airlines to raise fares to help offset increased fuel, labor and other costs. We cannot accurately predict the effect or duration of any economic slowdown or the timing or strength of a subsequent economic recovery.

In addition, we have significant obligations for aircraft and spare engines that we have ordered from Airbus and IAE (or any other engine manufacturer for future deliveries) over the next nine years, and we will need to finance these purchases. We may not have sufficient liquidity or creditworthiness to fund the purchase of aircraft and engines, including payment of PDPs, or for other working capital. Factors that affect our ability to raise financing or access the capital markets include market conditions in the airline industry, economic conditions, the perceived residual value of aircraft and related assets, the level and volatility of our earnings, our relative competitive position in the markets in which we operate, our ability to retain key personnel, our operating cash flows, and legal and regulatory developments. Regardless of our creditworthiness, at times the market for aircraft purchase or lease financing has been very constrained due to such factors as the general state of the capital markets and the financial position of the major providers of commercial aircraft financing.

Our liquidity and general level of capital resources impact our ability to hedge our fuel requirements.

As of December 31, 2012, we had fuel hedges using U.S. Gulf Coast jet fuel collars in place for approximately 5% of our 2013 anticipated fuel consumption. While we intend to hedge a portion of our future fuel requirements, there can be no assurance that, at any given time, we will be able to enter into fuel hedge contracts. In the past, we have not had and in the future we may not have sufficient creditworthiness or liquidity to post the collateral necessary to hedge our fuel requirements. Even if we are able to hedge portions of our future fuel requirements, we cannot guarantee that our hedge contracts will provide any particular level of protection against increased fuel costs or that our counterparties will be able to perform under our hedge contracts, such as in the case of a counterparty’s insolvency. Furthermore, our ability to react to the cost of fuel, absent hedging, is limited, because we set the price of tickets in advance of knowing our fuel costs at the time the tickets are flown. Our ability to pass on any significant increases in aircraft fuel costs through fare increases could also be limited.

We rely on maintaining a high daily aircraft utilization rate to implement our low cost structure, which makes us especially vulnerable to flight delays or cancellations or aircraft unavailability.

We maintain a high daily aircraft utilization rate. Our average daily aircraft utilization was 12.8 hours, 12.7 hours and 12.8 hours for 2012, 2011 and 2010, respectively. Aircraft utilization is the average amount of time per day that our aircraft spend carrying passengers. Our revenue per aircraft can be increased by high daily aircraft utilization, which is achieved in part by reducing turnaround times at airports, so we can fly more hours on average in a day. Aircraft utilization is reduced by delays and cancellations from various factors, many of which are beyond our control, including air traffic congestion at airports or other air traffic control problems, adverse weather conditions, increased security measures or breaches in security, international or domestic conflicts, terrorist activity, or other changes in business conditions. A significant portion of our operations are concentrated in markets such as South Florida, the Caribbean, Latin America and the Northeast and northern Midwest regions of the United States, which are particularly vulnerable to weather, airport traffic constraints and other delays. In addition, pulling aircraft out of service for unscheduled and scheduled maintenance, which will increase as our fleet ages, may materially reduce our average fleet utilization and require that we seek short-term substitute capacity at increased costs. Due to the relatively small size of our fleet and high daily aircraft utilization rate, the unavailability of one or more aircraft and resulting reduced capacity could have a material adverse effect on our business, results of operations, and financial condition.

Our maintenance costs will increase as our fleet ages, and we will periodically incur substantial maintenance costs due to the maintenance schedules of our aircraft fleet.

As of December 31, 2012, the average age of our aircraft was approximately 4.6 years. Our relatively new aircraft require less maintenance now than they will in the future. Our fleet will require more maintenance as it ages and our maintenance and repair expenses for each of our aircraft will be incurred at approximately the same intervals. Moreover, because our current fleet was acquired over a relatively short period, significant maintenance that is scheduled on each of these planes will occur at roughly the same time, meaning we will incur our most expensive scheduled maintenance obligations, known as heavy maintenance, across our present fleet around the same time. These more significant maintenance activities result in out-of-service periods during which our aircraft are dedicated to maintenance activities and unavailable to fly revenue service. In addition, the terms of some of our lease agreements require us to pay supplemental rent, also known as maintenance reserves, to the lessor in advance of the performance of major maintenance, resulting in our recording significant prepaid deposits on our balance sheet. We expect scheduled and unscheduled aircraft maintenance expenses to increase as a percentage of our revenue over the next several years. Any significant increase in maintenance and repair expenses would have a material adverse effect on our business, results of operations, and financial condition. Please see “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Critical Accounting Policies and Estimates—Aircraft Maintenance, Materials and Repair Costs and Heavy Maintenance Amortization” and “—Maintenance Reserves.”

Our lack of marketing alliances could harm our business.

Many airlines, including the domestic traditional network airlines (American, Delta, United and US Airways) have marketing alliances with other airlines, under which they market and advertise their status as marketing alliance partners. These alliances, such as OneWorld, SkyTeam and Star Alliance, generally provide for code-sharing, frequent flier program reciprocity, coordinated scheduling of flights to permit convenient connections and other joint marketing activities. Such arrangements permit an airline to market flights operated by other alliance members as its own. This increases the destinations, connections and frequencies offered by the airline and provides an opportunity to increase traffic on that airline’s segment of flights connecting with alliance partners. We currently do not have any alliances with U.S. or foreign airlines. Our lack of marketing alliances puts us at a competitive disadvantage to traditional network carriers who are able to attract passengers through more widespread alliances, particularly on international routes, and that disadvantage may result in a material adverse effect on our passenger traffic, business, results of operations and financial condition.

We are subject to extensive and increasing regulation by the Federal Aviation Administration, the Department of Transportation, and other U.S. and foreign governmental agencies, compliance with which could cause us to incur increased costs and adversely affect our business and financial results.

Airlines are subject to extensive and increasing regulatory and legal compliance requirements, both domestically and internationally, that involve significant costs. In the last several years, Congress has passed laws, and the DOT, FAA and TSA have issued regulations, relating to the operation of airlines that have required significant expenditures. We expect to continue to incur expenses in connection with complying with government regulations. Additional laws, regulations, taxes and increased airport rates and charges have been proposed from time to time that could significantly increase the cost of airline operations or reduce the demand for air travel. If adopted, these measures could have the effect of raising ticket prices, reducing revenue and increasing costs. For example, the DOT finalized rules, effective on April 29, 2010, requiring new procedures for customer handling during long onboard tarmac delays, as well as additional reporting requirements for airlines that could increase the cost of airline operations or reduce revenues. The DOT has been aggressively investigating alleged violations of the new rules. In addition, a second set of DOT final rules, which became effective in August 2011 and January 2012, addresses, among other things, concerns about how airlines handle interactions with passengers through advertising, the reservations process, at the airport and on board the aircraft, including requirements for disclosure of base fares plus a set of regulatorily dictated options and limits on cancellations and service charges for changes and cancellations. Failure to remain in full compliance with these rules may subject us to fines or other enforcement action, including requirements to modify our passenger reservations system, which could have a material effect on our business. The DOT has a pending notice of proposed rulemaking addressing additional accommodations required for passengers with certain disabilities and on December 21, 2011 announced a new final rule related to flight crew duty and rest requirements. We cannot assure you that compliance with these new rules will not have a material adverse effect on our business.

On August 3, 2010, the Airline Baggage Transparency and Accountability Act was introduced in the United States Senate. This legislation, if enacted, would increase disclosure regarding fees for airline ticket sales, impose federal taxes on charges for carry-on and checked baggage, authorize the DOT’s Aviation Consumer Protection Division to oversee lost and stolen baggage claims, and require data collection and the public release of collected data concerning airline handling of lost, damaged and stolen luggage. More recently, the United States Senate passed an amendment to the FAA reauthorization bill that, if enacted, would impose federal taxes at a rate of 7.5% on charges for carry-on baggage. If the Airline Baggage Transparency and Accountability Act, the Senate amendment to the FAA reauthorization bill or similar legislation were to be enacted, it is uncertain what effect it would have on our results of operations and financial condition.

We cannot assure you that these and other laws or regulations enacted in the future will not harm our business. In addition, the TSA mandates the federalization of certain airport security procedures and imposes additional security requirements on airports and airlines, most of which are funded by a per ticket tax on passengers and a tax on airlines. The federal government has on several occasions proposed a significant increase in the per ticket tax. The proposed ticket tax increase, if implemented, could negatively impact our financial results.

Our ability to operate as an airline is dependent on our maintaining certifications issued to us by the DOT and the FAA. The FAA has the authority to issue mandatory orders relating to, among other things, the grounding of aircraft, inspection of aircraft, installation of new safety-related items and removal and replacement of aircraft parts that have failed or may fail in the future. A decision by the FAA to ground, or require time consuming inspections of or maintenance on, our aircraft, for any reason, could negatively affect our business and financial results. Federal law requires that air carriers operating large aircraft be continuously “fit, willing and able” to provide the services for which they are licensed. Our “fitness” is monitored by the DOT, which considers factors such as unfair or deceptive competition, advertising, baggage liability and disabled passenger transportation. While the DOT has seldom revoked a carrier’s certification for lack of fitness, such an occurrence would render it impossible for us to continue operating as an airline. The DOT may also institute investigations or administrative proceedings against airlines for violations of regulations.

International routes are regulated by treaties and related agreements between the United States and foreign governments. Our ability to operate international routes is subject to change because the applicable arrangements between the United States and foreign governments may be amended from time to time. Our access to new international markets may be limited by our ability to obtain the necessary certificates to fly the international routes. In addition, our operations in foreign countries are subject to regulation by foreign governments and our business may be affected by changes in law and future actions taken by such governments, including granting or withdrawal of government approvals and restrictions on competitive practices. We are subject to numerous foreign regulations based on the large number of countries outside the United States where we currently provide service. If we are not able to comply with this complex regulatory regime, our business could be significantly harmed. Please see “Business—Government Regulation.”

We may not be able to implement our growth strategy.

Our growth strategy includes acquiring additional aircraft, increasing the frequency of flights and size of aircraft used in markets we currently serve and expanding the number of markets we serve where our low cost structure would likely be successful. Effectively implementing our growth strategy is critical for our business to achieve economies of scale and to sustain or increase our profitability. We face numerous challenges in implementing our growth strategy, including our ability to:


•	maintain profitability;


•	obtain financing to acquire new aircraft;


•	access airports located in our targeted geographic markets where we can operate routes in a manner that is consistent with our cost strategy;


•	gain access to international routes; and


•	access sufficient gates and other services at airports we currently serve or may seek to serve.

Our growth is dependent upon our ability to maintain a safe and secure operation and requires additional personnel, equipment and facilities. An inability to hire and retain personnel, timely secure the required equipment and facilities in a cost-effective manner, efficiently operate our expanded facilities or obtain the necessary regulatory approvals may adversely affect our ability to achieve our growth strategy, which could harm our business. In addition, expansion to new markets may have other risks due to factors specific to those markets. We may be unable to foresee all of the risks attendant upon entering certain new markets or respond adequately to these risks, and our growth strategy and our business may suffer as a result. In addition, our competitors may reduce their fares and/or offer special promotions following our entry into a new market. We cannot assure you that we will be able to profitably expand our existing markets or establish new markets.

Some of our target growth markets in the Caribbean and Latin America include countries with less developed economies that may be vulnerable to unstable economic and political conditions, such as significant fluctuations in gross domestic product, interest and currency exchange rates, civil disturbances, government instability, nationalization and expropriation of private assets and the imposition of taxes or other charges by governments. The occurrence of any of these events in markets served by us and the resulting instability may adversely affect our ability to implement our growth strategy.

In 2008, in response to record high fuel prices and rapidly deteriorating economic conditions, we modified our growth plans by terminating our leases for seven aircraft. We incurred significant expenses relating to our lease terminations, and have incurred additional expenses to acquire new aircraft in place of those under the terminated leases as we expand our network. We may in the future determine to reduce further our future growth plans from previously announced levels, which may impact our business strategy and future profitability.

We rely heavily on technology and automated systems to operate our business and any failure of these technologies or systems or failure by their operators could harm our business.

We are highly dependent on technology and automated systems to operate our business and achieve low operating costs. These technologies and systems include our computerized airline reservation system, flight operations system, financial planning, management and accounting system, telecommunications systems, website, maintenance systems and check-in kiosks. In order for our operations to work efficiently, our website and reservation system must be able to accommodate a high volume of traffic, maintain secure information and deliver flight information. Substantially all of our tickets are issued to passengers as electronic tickets. We depend on our reservation system, which is hosted and maintained under a long-term contract by a third-party service provider, to be able to issue, track and accept these electronic tickets. If our reservation system fails or experiences interruptions, and we are unable to book seats for any period of time, we could lose a significant amount of revenue as customers book seats on competing airlines. We have experienced short duration reservation system outages from time to time and may experience similar outages in the future. For example, in November 2010, we experienced a significant service outage with our third-party reservation service provider on the day before Thanksgiving, one of the industry’s busiest travel days. We also rely on third-party service providers of our other automated systems for technical support, system maintenance and software upgrades. If our automated systems are not functioning or if the current providers were to fail to adequately provide technical support or timely software upgrades for any one of our key existing systems, we could experience service disruptions, which could harm our business and result in the loss of important data, increase our expenses and decrease our revenues. In the event that one or more of our primary technology or systems’ vendors goes into bankruptcy, ceases operations or fails to perform as promised, replacement services may not be readily available on a timely basis, at competitive rates or at all and any transition time to a new system may be significant.

In addition, our automated systems cannot be completely protected against events that are beyond our control, including natural disasters, computer viruses or telecommunications failures. Substantial or sustained system failures could cause service delays or failures and result in our customers purchasing tickets from other airlines. We have implemented security measures and change control procedures and have disaster recovery plans; however, we cannot assure you that these measures are adequate to prevent disruptions. Disruption in, changes to or a breach of, these systems could result in a disruption to our business and the loss of important data. Any of the foregoing could result in a material adverse effect on our business, results of operations and financial condition.

We are subject to cyber security risks and may incur increasing costs in an effort to minimize those risks.

Our business employs systems and websites that allow for the secure storage and transmission of proprietary or confidential information regarding our customers, employees, suppliers and others, including personal identification information, credit card data, and other confidential information. Security breaches could expose us to a risk of loss or misuse of this information, litigation, and potential liability. Although we take steps to secure our management information systems, and although multiple auditors review and approve the security configurations and management processes of these systems, including our computer systems, intranet and internet sites, email and other telecommunications and data networks, the security measures we have implemented may not be effective, and our systems may be vulnerable to theft, loss, damage and interruption from a number of potential sources and events, including unauthorized access or security breaches, natural or man-made disasters, cyber attacks, computer viruses, power loss, or other disruptive events. We may not have the resources or technical sophistication to anticipate or prevent rapidly evolving types of cyber attacks. Attacks may be targeted at us, our customers and suppliers, or others who have entrusted us with information. In addition, attacks not targeted at us, but targeted solely at suppliers, may cause disruption to our computer systems or a breach of the data that we maintain on customers, employees, suppliers, and others.

Actual or anticipated attacks may cause us to incur increasing costs, including costs to deploy additional personnel and protection technologies, train employees, and engage third-party experts and consultants, or costs incurred in connection with the notifications to employees, suppliers, or the general public as part of our notification obligations to the various governments that govern our business. Advances in computer capabilities, new technological discoveries, or other developments may result in the breach or compromise of technology used by us to protect transaction or other data. In addition, data and security breaches can also occur as a result of non-technical issues, including breaches by us or by persons with whom we have commercial relationships that result in the unauthorized release of personal or confidential information. Our reputation, brand, and financial condition could be adversely affected if, as a result of a significant cyber event or other security issues: our operations are disrupted or shut down; our confidential, proprietary information is stolen or disclosed; we incur costs or are required to pay fines in connection with stolen customer, employee or other confidential information; we must dedicate significant resources to system repairs or increase cyber security protection; or we otherwise incur significant litigation or other costs.

Our processing, storage, use and disclosure of personal data could give rise to liabilities as a result of governmental regulation.

In the processing of our customer transactions, we receive, process, transmit and store a large volume of identifiable personal data, including financial data such as credit card information. This data is increasingly subject to legislation and regulation, typically intended to protect the privacy of personal data that is collected, processed and transmitted. More generally, we rely on consumer confidence in the security of our system, including our website on which we sell the majority of our tickets. Our business, results of operations and financial condition could be adversely affected if we are unable to comply with existing privacy obligations or legislation or regulations are expanded to require changes in our business practices.

We may not be able to maintain or grow our non-ticket revenues.

Our business strategy includes expanding our portfolio of ancillary products and services. There can be no assurance that passengers will pay for additional ancillary products and services or that passengers will continue to choose to pay for the ancillary products and services we currently offer. Further, regulatory initiatives could adversely affect ancillary revenue opportunities. Failure to maintain our non-ticket revenues would have a material adverse effect on our results of operations and financial condition. Furthermore, if we are unable to maintain and grow our non-ticket revenues, we may not be able to execute our strategy to continue to lower base fares in order to stimulate demand for air travel. Please see “—Restrictions on or increased taxes applicable to charges for ancillary products and services paid by airline passengers and burdensome consumer protection regulations or laws could harm our business, results of operations and financial condition.”

Our inability to expand or operate reliably or efficiently out of our key airports where we maintain a large presence could have a material adverse effect on our business, results of operations and financial condition.

We are highly dependent on markets served from airports where we maintain a large presence. Our results of operations may be affected by actions taken by governmental or other agencies or authorities having jurisdiction over our operations at airports, including, but not limited to:


•	increases in airport rates and charges;


•	limitations on take-off and landing slots, airport gate capacity or other use of airport facilities;


•	termination of our airport use agreements, some of which can be terminated by airport authorities with little notice to us;


•	increases in airport capacity that could facilitate increased competition;


•	international travel regulations such as customs and immigration;


•	increases in taxes;


•	changes in the law that affect the services that can be offered by airlines in particular markets and at particular airports;


•	restrictions on competitive practices;


•	the adoption of statutes or regulations that impact customer service standards, including security standards; and


•	the adoption of more restrictive locally-imposed noise regulations or curfews.

In general, any changes in airport operations could have a material adverse effect on our business, results of operations and financial condition.

We rely on third-party service providers to perform functions integral to our operations.

We have entered into agreements with third-party service providers to furnish certain facilities and services required for our operations, including ground handling, catering, passenger handling, engineering, maintenance, refueling, reservations and airport facilities as well as administrative and support services. We are likely to enter into similar service agreements in new markets we decide to enter, and there can be no assurance that we will be able to obtain the necessary services at acceptable rates.

Although we seek to monitor the performance of third parties that provide us with our reservation system, ground handling, catering, passenger handling, engineering, maintenance services, refueling and airport facilities, the efficiency, timeliness and quality of contract performance by third-party service providers are often beyond our control, and any failure by our service providers to perform their contracts may have an adverse impact on our business and operations. For example, in 2008, our call center provider went bankrupt. Though we were able to quickly switch to an alternative vendor, we experienced a significant business disruption during the transition period and a similar disruption could occur in the future if we changed call center providers or if an existing provider ceased to be able to serve us. We expect to be dependent on such third-party arrangements for the foreseeable future.

We rely on third-party distribution channels to distribute a portion of our airline tickets.

We rely on third-party distribution channels, including those provided by or through global distribution systems, or GDSs, conventional travel agents and online travel agents, or OTAs, to distribute a portion of our airline tickets, and we expect in the future to rely on these channels to an increasing extent to collect ancillary revenues. These distribution channels are more expensive and at present have less functionality in respect of ancillary revenues than those we operate ourselves, such as our call centers and our website. Certain of these distribution channels also effectively restrict the manner in which we distribute our products generally. To remain competitive, we will need to successfully manage our distribution costs and rights, and improve the functionality of third-party distribution channels, while maintaining an industry-competitive cost structure. Negotiations with key GDSs and OTAs designed to manage our costs, increase our distribution flexibility, and improve functionality could be contentious, could result in diminished or less favorable distribution of our tickets, and may not provide the functionality we require to maximize ancillary revenues. Any inability to manage our third-party distribution costs, rights and functionality at a competitive level or any material diminishment in the distribution of our tickets could have a material adverse effect on our competitive position and our results of operations. Moreover, our ability to compete in the markets we

serve may be threatened by changes in technology or other factors that may make our existing third-party sales channels impractical, uncompetitive, or obsolete.

We rely on a single service provider to manage our fuel supply.

As of December 31, 2012, we had a single fuel service contract with World Fuel Services Corporation to manage the sourcing and contracting of our fuel supply with our third-party vendors. A failure by this provider to fulfill its obligations could have a material adverse effect on our business, results of operations and financial condition.

Our reputation and business could be adversely affected in the event of an emergency, accident or similar incident involving our aircraft.

We are exposed to potential significant losses in the event that any of our aircraft is subject to an emergency, accident, terrorist incident or other similar incident, and significant costs related to passenger claims, repairs or replacement of a damaged aircraft and its temporary or permanent loss from service. There can be no assurance that we will not be affected by such events or that the amount of our insurance coverage will be adequate in the event such circumstances arise and any such event could cause a substantial increase in our insurance premiums. Please see “—Increases in insurance costs or significant reductions in coverage could have a material adverse effect on our business, financial condition and results of operations.” In addition, any future aircraft emergency, accident or similar incident, even if fully covered by insurance or even if it does not involve our airline, may create a public perception that our airline or the equipment we fly is less safe or reliable than other transportation alternatives, which could have an adverse impact on our reputation and could have a material adverse effect on our business, results of operations and financial condition.

Negative publicity regarding our customer service could have a material adverse effect on our business.

In the past we have experienced a relatively high number of customer complaints related to, among other things, our customer service, and reservations and ticketing systems. In particular, we generally experience a higher volume of complaints when we make changes to our unbundling policies, such as charging for baggage. In addition, in 2009, we entered into a consent order with the DOT for our procedures for bumping passengers from oversold flights and our handling of lost or damaged baggage. Under the consent order, we were assessed a civil penalty of $375,000, of which we were required to pay $215,000 based on an agreement with the DOT and our not having similar violations in the year after the date of the consent order. Our reputation and business could be materially adversely affected if we fail to meet customers’ expectations with respect to customer service or if we are perceived by our customers to provide poor customer service.

We depend on a limited number of suppliers for our aircraft and engines.

One of the elements of our business strategy is to save costs by operating a single-family aircraft fleet - currently Airbus A320-family, single-aisle aircraft, powered by engines manufactured by IAE. If Airbus or IAE (or any other engine manufacturer for future deliveries) becomes unable to perform its contractual obligations, or if we are unable to acquire or lease aircraft or engines from other owners, operators or lessors on acceptable terms, we would have to find other suppliers for a similar type of aircraft or engine. If we have to lease or purchase aircraft from another supplier, we would lose the significant benefits we derive from our current single fleet composition. We may also incur substantial transition costs, including costs associated with retraining our employees, replacing our manuals and adapting our facilities and maintenance programs. Our operations could also be harmed by the failure or inability of aircraft, engine and parts suppliers to provide sufficient spare parts or related support services on a timely basis. Our business would be significantly harmed if a design defect or mechanical problem with any of the types of aircraft or components that we operate were discovered that would ground any of our aircraft while the defect or problem was corrected, assuming it could be corrected at all. The use of our aircraft could be suspended or restricted by regulatory authorities in the event of any actual or perceived mechanical or design problems. Our business would also be significantly harmed if the public began to avoid flying with us due to an adverse perception of the types of aircraft that we operate stemming from safety concerns or other problems, whether real or perceived, or in the event of an accident involving those types of aircraft or components. Carriers that operate a more diversified fleet are better positioned than we are to manage such events.

Reduction in demand for air transportation, or governmental reduction or limitation of operating capacity, in the South Florida, Caribbean, Latin American or Northeast U.S. markets could harm our business, results of operations and financial condition.

A significant portion of our operations are conducted to and from the South Florida, Caribbean, Latin American or Northeast U.S. markets. Our business, results of operations and financial condition could be harmed if we lost our authority to fly to these markets, by any circumstances causing a reduction in demand for air transportation, or by governmental reduction or limitation of operating capacity, in these markets, such as adverse changes in local economic or political conditions, negative

public perception of these destinations, unfavorable weather conditions, or terrorist related activities. Furthermore, our business could be harmed if jurisdictions that currently limit competition allow additional airlines to compete on routes we serve. Many of the countries we serve are experiencing either economic slowdowns or recessions, which may translate into a weakening of demand and could harm our business, results of operations and financial condition.

Increases in insurance costs or significant reductions in coverage could have a material adverse effect on our business, financial condition and results of operations.

We carry insurance for public liability, passenger liability, property damage and all-risk coverage for damage to our aircraft. As a result of the September 11, 2001 terrorist attacks, aviation insurers significantly reduced the amount of insurance coverage available to commercial air carriers for liability to persons other than employees or passengers for claims resulting from acts of terrorism, war or similar events (war risk insurance). Accordingly, our insurance costs increased significantly and our ability to continue to obtain certain types of insurance remains uncertain. While the price of commercial insurance has declined since the period immediately after the terrorist attacks, in the event commercial insurance carriers further reduce the amount of insurance coverage available to us, or significantly increase its cost, we would be adversely affected. We currently maintain commercial airline insurance with several underwriters. However, there can be no assurance that the amount of such coverage will not be changed, or that we will not bear substantial losses from accidents. We could incur substantial claims resulting from an accident in excess of related insurance coverage that could have a material adverse effect on our results of operations and financial condition.

We have obtained third-party war risk insurance, which insures against some risks of terrorism, through a special program administered by the FAA, resulting in lower premiums than if we had obtained this insurance in the commercial insurance market. If the special program administered by the FAA is not continued, or if the government discontinues this coverage for any reason, obtaining comparable coverage from commercial underwriters could result in substantially higher premiums and more restrictive terms, if it is available at all. Our business, results of operations and financial condition could be materially adversely affected if we are unable to obtain adequate war risk insurance. The FAA war risk hull and liability insurance policy is effective from October 1, 2012 through September 30, 2013.

Failure to comply with applicable environmental regulations could have a material adverse effect on our business, results of operations and financial condition.

We are subject to increasingly stringent federal, state, local and foreign laws, regulations and ordinances relating to the protection of the environment, including those relating to emissions to the air, discharges to surface and subsurface waters, safe drinking water, and the management of hazardous substances, oils and waste materials. Compliance with all environmental laws and regulations can require significant expenditures and any future regulatory developments in the United States and abroad could adversely affect operations and increase operating costs in the airline industry. For example, climate change legislation was previously introduced in Congress and such legislation could be re-introduced in the future by Congress and state legislatures, and could contain provisions affecting the aviation industry, compliance with which could result in the creation of substantial additional costs to us. Similarly, the Environmental Protection Agency issued a rule that regulates larger emitters of greenhouse gases. Future operations and financial results may vary as a result of such regulations. Compliance with these regulations and new or existing regulations that may be applicable to us in the future could increase our cost base and could have a material adverse effect on our business, results of operations and financial condition.

Governmental authorities in several U.S. and foreign cities are also considering or have already implemented aircraft noise reduction programs, including the imposition of nighttime curfews and limitations on daytime take-offs and landings. We have been able to accommodate local noise restrictions imposed to date, but our operations could be adversely affected if locally-imposed regulations become more restrictive or widespread.

If we are unable to attract and retain qualified personnel or fail to maintain our company culture, our business, results of operations and financial condition could be harmed.

Our business is labor intensive. We require large numbers of pilots, flight attendants, maintenance technicians and other personnel. The airline industry has from time to time experienced a shortage of qualified personnel, particularly with respect to pilots and maintenance technicians. In addition, as is common with most of our competitors, we have faced considerable turnover of our employees. We may be required to increase wages and/or benefits in order to attract and retain qualified personnel. If we are unable to hire, train and retain qualified employees, our business could be harmed and we may be unable to implement our growth plans.

In addition, as we hire more people and grow, we believe it may be increasingly challenging to continue to hire people who will maintain our company culture. Our company culture, which we believe is one of our competitive strengths, is important to providing high-quality customer service and having a productive, accountable workforce that helps keep our costs

low. As we continue to grow, we may be unable to identify, hire or retain enough people who meet the above criteria, including those in management or other key positions. Our company culture could otherwise be adversely affected by our growing operations and geographic diversity. If we fail to maintain the strength of our company culture, our competitive ability and our business, results of operations and financial condition could be harmed.

Our business, results of operations and financial condition could be materially adversely affected if we lose the services of our key personnel.

Our success depends to a significant extent upon the efforts and abilities of our senior management team and key financial and operating personnel. In particular, we depend on the services of our senior management team, including Ben Baldanza, our President and Chief Executive Officer. Competition for highly qualified personnel is intense, and the loss of any executive officer, senior manager or other key employee without adequate replacement or the inability to attract new qualified personnel could have a material adverse effect on our business, results of operations and financial condition. We do not maintain key-man life insurance on our management team.

Ownership by our principal stockholders could adversely affect our other stockholders.

As of February 11, 2013, entities affiliated with Indigo Partners, or Indigo, a private equity firm, beneficially owned approximately 16.6% of our outstanding common stock. As a result of its ownership positions, Indigo is able to exert a significant degree of influence or actual control over our management and affairs and over matters requiring stockholder approval, including the nomination and election of directors, a merger, consolidation or sale of all or substantially all of our assets and other significant business or corporate transactions. Indigo's ownership interest may limit the ability of other stockholders to influence corporate matters and, as a result, we may take actions that our other stockholders do not view as beneficial. For example, this substantial ownership stake could have the effect of delaying or preventing a change in control or otherwise discouraging a potential acquirer from attempting to obtain control of us, which in turn could cause the market price of our common stock to decline or prevent our stockholders from realizing a premium over the market price for their common stock.

The requirements of being a public company may strain our resources, divert management’s attention and affect our ability to attract and retain qualified board members.

As a public company, we incur significant legal, accounting and other expenses that we did not incur as a private company, including costs associated with public company reporting requirements. We also have incurred and will incur costs associated with the Sarbanes-Oxley Act of 2002, as amended, the Dodd-Frank Wall Street Reform and Consumer Protection Act and related rules implemented or to be implemented by the SEC and the NASDAQ Stock Market. The expenses incurred by public companies generally for reporting and corporate governance purposes have been increasing. We expect these rules and regulations to increase our legal and financial compliance costs and to make some activities more time-consuming and costly, although we are currently unable to estimate these costs with any degree of certainty. These laws and regulations could also make it more difficult or costly for us to obtain certain types of insurance, including director and officer liability insurance, and we may be forced to accept reduced policy limits and coverage or incur substantially higher costs to obtain the same or similar coverage. These laws and regulations could also make it more difficult for us to attract and retain qualified persons to serve on our board of directors, our board committees or as our executive officers and may divert management’s attention. Furthermore, if we are unable to satisfy our obligations as a public company, we could be subject to delisting of our common stock, fines, sanctions and other regulatory action and potentially civil litigation.

We are required to assess our internal control over financial reporting on an annual basis, and any future adverse findings from such assessment could result in a loss of investor confidence in our financial reports, significant expenses to remediate any internal control deficiencies and ultimately have an adverse effect on the market price of our common stock.

Pursuant to Section 404 of the Sarbanes-Oxley Act of 2002, as amended, our management is required to report on, and our independent registered public accounting firm to attest to, the effectiveness of our internal control over financial reporting. The rules governing the standards that must be met for management to assess our internal control over financial reporting are complex and require significant documentation, testing and possible remediation. Annually, we perform activities that include reviewing, documenting, and testing our internal control over financial reporting. During the performance of these activities, we may encounter problems or delays in completing the implementation of any changes necessary to make a favorable assessment of our internal control over financial reporting. In connection with the attestation process by our independent registered public accounting firm, we may encounter problems or delays in completing the implementation of any requested improvements and receiving a favorable attestation. In addition, if we fail to maintain the adequacy of our internal control over financial reporting we will not be able to conclude on an ongoing basis that we have effective internal control over financial reporting in accordance with Section 404. If we fail to achieve and maintain an effective internal control environment, we

could suffer material misstatements in our financial statements and fail to meet our reporting obligations, which would likely cause investors to lose confidence in our reported financial information. This could harm our operating results and lead to a decline in our stock price. Additionally, ineffective internal control over financial reporting could expose us to increased risk of fraud or misuse of corporate assets and subject us to potential delisting from the NASDAQ Global Select Market, regulatory investigations, civil or criminal sanctions and class action litigation.

The market price of our common stock may be volatile, which could cause the value of an investment in our stock to decline.

The market price of our common stock may fluctuate substantially due to a variety of factors, many of which are beyond our control, including:


•	announcements concerning our competitors, the airline industry or the economy in general;


•	strategic actions by us or our competitors, such as acquisitions or restructurings;


•	media reports and publications about the safety of our aircraft or the aircraft type we operate;


•	new regulatory pronouncements and changes in regulatory guidelines;


•	changes in the price of aircraft fuel;


•	announcements concerning the availability of the type of aircraft we use;


•	general and industry-specific economic conditions;


•	changes in financial estimates or recommendations by securities analysts or failure to meet analysts’ performance expectations;


•	sales of our common stock or other actions by investors with significant shareholdings;


•	trading strategies related to changes in fuel or oil prices; and


•	general market, political and economic conditions.

The stock markets in general have experienced substantial volatility that has often been unrelated to the operating performance of particular companies. These types of broad market fluctuations may adversely affect the trading price of our common stock.

In the past, stockholders have sometimes instituted securities class action litigation against companies following periods of volatility in the market price of their securities. Any similar litigation against us could result in substantial costs, divert management’s attention and resources, and harm our business or results of operations.

If securities or industry analysts do not publish research or reports about our business, or publish negative reports about our business, our stock price and trading volume could decline.

The trading market for our common stock depends in part on the research and reports that securities or industry analysts publish about us or our business. If one or more of the analysts who cover us downgrade our stock or publish inaccurate or unfavorable research about our business, our stock price would likely decline. If one or more of these analysts cease coverage of our company or fail to publish reports on us regularly, demand for our stock could decrease, which might cause our stock price and trading volume to decline.

Our anti-takeover provisions may delay or prevent a change of control, which could adversely affect the price of our common stock.

Our amended and restated certificate of incorporation and amended and restated bylaws contain provisions that may make it difficult to remove our board of directors and management and may discourage or delay “change of control” transactions, which could adversely affect the price of our common stock. These provisions include, among others:


•	our board of directors is divided into three classes, with each class serving for a staggered three-year term, which prevents stockholders from electing an entirely new board of directors at an annual meeting;


•	actions to be taken by our stockholders may only be effected at an annual or special meeting of our stockholders and not by written consent;


•	special meetings of our stockholders can be called only by the Chairman of the Board or by our corporate secretary at the direction of our board of directors;


•	advance notice procedures that stockholders must comply with in order to nominate candidates to our board of directors and propose matters to be brought before an annual meeting of our stockholders may discourage or deter a potential acquirer from conducting a solicitation of proxies to elect the acquirer’s own slate of directors or otherwise attempting to obtain control of our company; and


•	our board of directors may, without stockholder approval, issue series of preferred stock, or rights to acquire preferred stock, that could dilute the interest of, or impair the voting power of, holders of our common stock or could also be used as a method of discouraging, delaying or preventing a change of control.

The value of our common stock may be adversely affected by additional issuances of common stock or preferred stock by us or sales by our principal stockholders.

Any future issuances or sales of our common stock by us will be dilutive to our existing common stockholders. Indigo (and its affiliates) hold approximately 12.1 million shares of our common stock or 16.6% of our common stock outstanding as of February 11, 2013, and are entitled to rights with respect to registration of such shares under the Securities Act. Sales of substantial amounts of our common stock in the public or private market, a perception in the market that such sales could occur, or the issuance of securities exercisable or convertible into our common stock, could adversely affect the prevailing price of our common stock.

Our corporate charter and bylaws include provisions limiting voting by non-U.S. citizens and specifying an exclusive forum for stockholder disputes.

To comply with restrictions imposed by federal law on foreign ownership of U.S. airlines, our amended and restated certificate of incorporation and amended and restated bylaws restrict voting of shares of our common stock by non-U.S. citizens. The restrictions imposed by federal law currently require that no more than 25% of our stock be voted, directly or indirectly, by persons who are not U.S. citizens, and that our president and at least two-thirds of the members of our board of directors and senior management be U.S. citizens. Our amended and restated bylaws provide that the failure of non-U.S. citizens to register their shares on a separate stock record, which we refer to as the “foreign stock record,” would result in a suspension of their voting rights in the event that the aggregate foreign ownership of the outstanding common stock exceeds the foreign ownership restrictions imposed by federal law.

Our amended and restated bylaws further provide that no shares of our common stock will be registered on the foreign stock record if the amount so registered would exceed the foreign ownership restrictions imposed by federal law. If it is determined that the amount registered in the foreign stock record exceeds the foreign ownership restrictions imposed by federal law, shares will be removed from the foreign stock record in reverse chronological order based on the date of registration therein, until the number of shares registered therein does not exceed the foreign ownership restrictions imposed by federal law. We are currently in compliance with these ownership restrictions.

As of February 11, 2013, based on our foreign stock registry, non-U.S. citizens own, in the aggregate, 14.8 million shares of common stock (approximately 20.4% of our common stock outstanding). As of February 11, 2013, there are no shares of non-voting common stock outstanding. When shares of non-voting common stock are outstanding, the holders of such stock may convert such shares, on a share-for-share basis, in the order reflected on our foreign stock record as shares of common stock are sold or otherwise transferred by non-U.S. citizens to U.S. citizens.

Our amended and restated certificate of incorporation also specifies that the Court of Chancery of the State of Delaware shall be the exclusive forum for substantially all disputes between us and our stockholders.

We do not intend to pay cash dividends for the foreseeable future.

We have never declared or paid cash dividends on our common stock. We currently intend to retain our future earnings, if any, to finance the further development and expansion of our business and do not intend to pay cash dividends in the foreseeable future. Any future determination to pay dividends will be at the discretion of our board of directors and will depend on our financial condition, results of operations, capital requirements, restrictions contained in current or future financing instruments, business prospects and such other factors as our board of directors deems relevant.

* Table reflects deliveries net of contractual lease returns. Table excludes five A320 NEO aircraft for which the Company has signed a Letter of Intent with International Lease Finance Corporation (ILFC), however delivery dates are contingent upon the engine type selection which has not yet been determined. Actual fleet count may differ depending on future fleet decisions, including actual lease retirements.

We also have a contractual purchase commitment for three spare V2500 IAE International Aero Engines AG engines scheduled for delivery from 2013 through 2015.

Ground Facilities

We lease all of our facilities at each of the airports we serve. Our leases for terminal passenger service facilities, which include ticket counter and gate space, operations support areas and baggage service offices, generally have a term ranging from month-to-month to 20 years, and contain provisions for periodic adjustments of lease rates. We also are responsible for maintenance, insurance and other facility-related expenses and services. We also have entered into use agreements at many of the airports we serve that provide for the non-exclusive use of runways, taxiways and other facilities. Landing fees under these agreements are based on the number of landings and weight of the aircraft.

As of December 31, 2012, Ft. Lauderdale/Hollywood International Airport (FLL) remained our single largest airport served, with over 20% of our capacity operating to or from FLL during 2012. We operate primarily out of the international terminal, Terminal 4, with occasional use of a gate in Terminal 3. We currently use up to ten gates at Terminal 4. We have preferential access to seven of the Terminal 4 gates, common use access to the remaining three Terminal 4 gates, and common use access to Terminal 3 gates. FLL is planning a Terminal 4 concourse replacement and expansion project, which would expand the number of gates at Terminal 4 to 14. Other airports through which we conduct significant operations include McCarran International Airport (LAS), Chicago O'Hare International Airport (ORD), Dallas-Fort Worth International Airport (DFW), Detroit Metropolitan Wayne County Airport (DTW), Atlantic City International Airport (ACY), and LaGuardia Airport (LGA).

Our largest maintenance facility is currently located in a leased facility at FLL under a lease that expires in January 2015. We also conduct additional maintenance operations in leased facilities in Detroit, Michigan; Atlantic City, New Jersey; Dallas, Texas; and Las Vegas, Nevada.

Our principal executive offices and headquarters are located in a leased facility at 2800 Executive Way, Miramar, Florida 33025, consisting of approximately 56,000 square feet. The lease for this facility expires in January 2015. We also have a training center located in a leased facility at 1100 Lee Wagener Boulevard, Fort Lauderdale, Florida 33315, consisting of approximately 10,000 square feet, under a lease that expires in January 2015.

ITEM 3. LEGAL PROCEEDINGS

We are subject to commercial litigation claims and to administrative and regulatory proceedings and reviews that may be asserted or maintained from time to time. We believe the ultimate outcome of pending lawsuits, proceedings and reviews will not, individually or in the aggregate, have a material adverse effect on our financial position, liquidity, or results of operations.

ITEM 4. MINE SAFETY DISCLOSURES

ITEM 5. MARKET FOR REGISTRANT'S COMMON EQUITY, RELATED STOCKHOLDER MATTERS, AND ISSUER PURCHASES OF EQUITY SECURITIES

Market Price of our common stock

Our common stock has been listed and traded on the NASDAQ Global Select Market under the symbol SAVE since May 26, 2011 when our IPO priced at $12.00 per share. Prior to that time, there was no public market for our common stock. The following table shows, for the periods indicated, the high and low per share sales prices for our common stock on the NASDAQ Global Select Market.



	High		Low
Fiscal year ending December 31, 2011
Second Quarter (from May 26, 2011)	$	12.33	$	11.11

Third Quarter	23.13		15.85
Fourth Quarter	18.00		15.64

As of February 11, 2013, there were approximately 23 holders of record of our common stock. Because many of our shares are held by brokers and other institutions on behalf of stockholders, we are unable to estimate the total number of stockholders represented by these record holders.

The information under the caption “Equity Compensation Plan Information” in our 2013 Proxy Statement is incorporated herein by reference.

Dividend Policy

We have never declared or paid, and do not anticipate declaring or paying, any cash dividends on our common stock. Any future determination as to the declaration and payment of dividends, if any, will be at the discretion of our board of directors and will depend on then existing conditions, including our financial condition, operating results, contractual restrictions, capital requirements, business prospects and other factors our board of directors may deem relevant.

Our Repurchases of Equity Securities

The following table reflects our repurchases of our common stock during the fourth quarter of 2012. All stock repurchases during this period were made from employees who received restricted stock grants. All stock repurchases were made at the election of each employee pursuant to an offer to repurchase by us. In each case, the shares repurchased constituted the portion of vested shares necessary to satisfy minimum withholding tax requirements.

During the first three quarters of 2012, we repurchased and retired 46,718 shares for a total of $0.9 million. All stock repurchases were made at the election of each employee pursuant to an offer to repurchase by us. In each case, the shares repurchased constituted the portion of vested shares necessary to satisfy withholding tax requirements. We did not make any open market stock repurchases during the fourth quarter of 2012.

Stock Performance Graph

The following graph compares the cumulative total stockholder return on our common stock with the cumulative total return on the NASDAQ Composite Index and the NYSE ARCA Airline Index for the period beginning on May 26, 2011 (the date our common stock was first traded) and ending on the last day of 2012. The graph assumes an investment of $100 in our stock and the two indices, respectively, on May 26, 2011, and further assumes the reinvestment of all dividends. The May 26, 2011 stock price used for our stock is the initial public offering price.

(1)

We estimate that the 2010 pilot strike had a net negative impact on our operating income for 2010 of approximately $24 million consisting of an estimated $28 million in lost revenues and approximately $4 million of incremental costs resulting from the strike, offset in part by a reduction of variable expenses during the strike of approximately $8 million for flights not flown. Additionally, under the terms of the pilot contract, we also paid $2.3 million in return-to-work payments during the second quarter, which are not included in the strike impact costs described above.


(2)	Aircraft fuel expense is the sum of (i) “into-plane fuel cost,” which includes the cost of jet fuel and certain other charges such as fuel taxes and oil, (ii) settlement gains and losses and (iii) unrealized mark-to-market gains and losses associated with fuel hedge contracts. The following table summarizes the components of aircraft fuel expense for the periods presented:



	Year Ended December 31,
	2012		2011			2010			2009			2008 (*)
	(in thousands)
Into-plane fuel cost	$	471,542	$	392,278		$	251,754		$	181,806		$	359,097
Realized losses (gains)	175		(7,436		)	(1,483		)	750			(69,876		)
Unrealized losses (gains)	46		3,204			(2,065		)	(1,449		)	9,873
Aircraft fuel expense	$	471,763	$	388,046		$	248,206		$	181,107		$	299,094



(*)	In July 2008, we monetized all of our fuel hedge contracts, which included hedges that had scheduled settlement dates during the remainder of 2008 and in 2009. We recognized a gain of $37.8 million representing cash received upon monetization of these contracts, of which a gain of $14.2 million related to 2009 fuel hedge positions on these contracts.

(3)

Special charges (credits) include: (i) for 2008 and 2009, amounts relating to the early termination in mid-2008 of leases for seven Airbus A319 aircraft, a related reduction in workforce and the exit facility costs associated with returning planes to lessors in 2008; (ii) for 2009 and 2010, amounts relating to the sale of previously expensed MD-80 parts; (iii) for 2010 and 2011 amounts relating to exit facility costs associated with moving our Detroit, Michigan maintenance operations to Fort Lauderdale, Florida; (iv) termination costs in connection with the IPO during the three months ended June 30, 2011 comprised of amounts paid to Indigo Partners, LLC to terminate its professional services agreement with us and fees paid to three individual, unaffiliated holders of our subordinated notes; and (v) for 2011 and 2012, a $9.1 million gain related to the sale of four permanent air carrier slots at Ronald Reagan National Airport (DCA) offset by legal, accounting, printing, and filing fees connected with the 2012 secondary offerings. For more information, please see “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Our Operating Expenses—Special Charges (Credits).”


(4)	Substantially all of the interest expense recorded in 2008, 2009, 2010 and 2011 relates to notes and preferred stock held by our principal stockholders that were repaid or redeemed, or exchanged for shares of common stock, in connection with the Recapitalization in 2011 that was effected in connection with the IPO. Interest expense in 2012 primarily relates to interest on pre-delivery deposits.


(5)	Interest attributable to funds used to finance the acquisition of new aircraft, including PDPs is capitalized as an additional cost of the related asset. Interest is capitalized at the weighted average implicit lease rate of our aircraft.


(6)	Gain on extinguishment of debt represents the recognition of contingencies provided for in our 2006 recapitalization agreements, which provided for the cancellation of shares of Class A preferred stock and reduction of the liquidation preference of the remaining Class A preferred stock and associated accrued but unpaid dividends based on the outcome of the contingencies.


(7)	Net income for 2010 includes a $52.3 million net tax benefit primarily due to the release of a valuation allowance resulting in a deferred tax benefit of $52.8 million in 2010. Absent the release of the valuation allowance and corresponding tax benefit, our net income would have been $19.7 million for 2010.

ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

You should read the following discussion of our financial condition and results of operations in conjunction with the financial statements and the notes thereto included elsewhere in this annual report.

2012 Year in Review

The year 2012 proved to be one of the most successful years on record for the Company. We reported profitability for the sixth consecutive year, earning $108.5 million ($1.49 per share, diluted), compared to net income of $76.4 million ($1.43 per share, diluted) in 2011. Our continuous effort to preserve our low cost structure and to offer separately a range of optional services allowed us to offer low base fares which drove strong customer demand during 2012. In addition, our ability to adjust our capacity and routes in response to changing market conditions allowed us to increase our profitability year over year.

We achieved a 13.2% operating profit margin on $1.3 billion in operating revenues, despite an estimated $25 million in lost revenues caused by operational disruptions related to Hurricane Sandy. Our traffic grew by 20.7% as we continued to stimulate demand with low fares, evidenced by our ability to reduce our average ticket revenue per passenger flight segment by $5.86 or 7.2% to $75.11. In addition to the effect of the storm during 2012, we also experienced increases in energy prices as well as additional maintenance costs as a result of our seat maintenance program. Our fuel expense increased $83.7 million, or 21.6%, to $471.8 million during 2012 as compared to 2011 mainly as a result of our increased flight volume of 19.9% coupled with increases in fuel cost per gallon of 3.8% year over year. During 2012, we introduced and completed a new seat maintenance program which added $6.8 million in one-time start-up costs to maintenance expenses.

Our operating cost structure has been a primary area of focus since 2007, when we decided to compete solely on the basis of fare price and implemented our ULCC business model. Spirit's unit operating costs continue to be among the lowest of any airline in the Americas. During 2012, we expanded our fleet of Airbus single-aisle aircraft from 37 to 45. Our high-density seating configuration allows us to be the "greenest" major airline in the United States, because we burn less fuel per passenger than our competitors. We grew our capacity in 2012 by 21.3%, expanding into five new destinations - Phoenix/Mesa, Arizona; Denver, Colorado; Houston, Texas; Minneapolis/St. Paul, Minnesota; and Los Cabos, Mexico. In 2012, we announced the opening of crew and maintenance bases in Las Vegas, Nevada and in Dallas/Fort Worth, Texas to help support the expansion of our operation to destinations in the Western United States, and drive overall lower operating costs.

Driving increased ancillary revenue also continues to be a primary focus. In 2012, we increased our average non-ticket revenue per passenger flight segment by 14.7%, or $6.60, to $51.39. Our total non-ticket revenue increased by 40.4%, or $154.1 million, to $535.6 million in 2012. In late 2011, we increased our domestic passenger usage fee, while decreasing many of the corresponding base fares, which drove much of the increase in non-ticket revenue per passenger segment and the decrease in ticket revenue per passenger segment in 2012. In addition, we restructured our bag charges in an effort to encourage customers to pre-pay for bags on the website rather than at the airport or the gate. We also continued to grow non-ticket revenues by offering travel-related options such as hotels and rental cars for sale through our website, through our $9 Fare Club, and other options to enhance our customers' travel experience.

During 2012, our unit operating costs excluding fuel and special charges (credits) (Adjusted CASM excluding fuel) increased by 4.9% to 6.00 cents. The increase on a per-unit basis is primarily due to increases in maintenance costs, depreciation and amortization, and certain costs within other operating expenses. The increase in maintenance costs is due primarily to the one-time start-up costs of our seat maintenance program. The increase in depreciation and amortization is related to the increase in scheduled heavy maintenance events on our aircraft. We use the deferral method of accounting for scheduled heavy maintenance checks, and therefore, once the event is performed, we capitalize the associated costs and amortize the expense over time until the earlier of the end of the remaining lease term or until the next scheduled heavy maintenance event. Many of the markets we added in 2012, as well as the run-rate effect of those added during 2011, have higher average operating costs which, in addition to contributing to increases in other rents and landing fees, drove increases in station-related costs that are accounted for under other operating expenses. In addition, prior to our crew base openings in Las Vegas, Nevada and Dallas, Texas in 2012, our network scope changes drove higher crew-related expenses as result of increased hotel volumes at higher average rates. We also experienced higher passenger re-accommodation expenses associated with flight cancellations during 2012.

On December 2011, we signed a new agreement with Airbus for the delivery of 75 Airbus A320 aircraft. As of December 31, 2012, our firm order with Airbus (including under our old purchase agreement) and a third party consisted of 106 A320 family aircraft scheduled for delivery through 2021. Our plan calls for growing the fleet by 21.5% in 2013.

2011 IPO

On June 1, 2011, we completed our initial public offering of common stock, or IPO, which raised net proceeds of $150.0 million after repayment of debt, payment of transaction expenses and other fees. In connection with the IPO, we effected a recapitalization, which we refer to as the 2011 Recapitalization, that resulted in the repayment or conversion of all of our notes and shares of preferred stock into shares of common stock.

2010 Pilot Strike

On May 13, 2010, the NMB released us and the pilots’ union from mandatory supervised mediation, which commenced a 30-day “cooling off” period as provided in the RLA. On June 12, 2010, following several negotiation sessions with the pilots’ union during the cooling off period that did not result in an agreement, our pilots declared a strike, and we were forced to suspend all flight operations. The parties reached a tentative agreement on June 16, 2010 under a Return to Work Agreement, and a full flight schedule was resumed on June 18, 2010. On July 23, 2010, the pilots ratified a five-year collective bargaining agreement that became effective on August 1, 2010.

The results of operations for 2010 were materially adversely affected by the pilot strike. The pilot strike resulted in reduced bookings in the period leading up to the strike as our customers became aware of the impending end of the cooling off period, and lost revenues while flight operations were shut down and while we recovered from the strike. We also experienced additional expenses related to the strike, including costs to reaccommodate passengers, offset by reduced variable expenses, such as reduced fuel consumption and employee costs for flights not operated. We estimate that the strike had a net negative impact on our operating income for 2010 of approximately $24 million, resulting from an estimated $28 million in lost revenues and approximately $4 million of incremental costs, offset in part by a reduction of variable expenses during the strike of approximately $8 million for flights not flown. The strike resulted in a reduction of approximately 145.8 million ASMs from our scheduled flying that was suspended during the five-day strike period. Additionally, under the terms of the pilot contract, we also paid $2.3 million in return-to-work payments during the second quarter of 2010, which are not included in the strike impact costs described above.

The agreement with our pilots increased our pilot labor costs by approximately 11% in 2011 compared to the estimated cost of the previous collective bargaining agreement and includes additional pay rate increases and modified work rules, which will increase the productivity of our pilots. We believe the five-year term is valuable in providing stability to our labor costs, and that the other terms will also provide us with competitive pilot labor costs compared to other U.S.-based low-cost carriers.

Our Operating Revenues

Our operating revenues are comprised of passenger revenues and non-ticket revenues.

Passenger Revenues. Passenger revenues consist of the base fares that customers pay for air travel, which fares include government-imposed taxes and fees.

Non-ticket Revenues. Non-ticket revenues are generated from air travel-related charges for baggage, bookings through our distribution channels, advance seat selection, itinerary changes, hotel travel packages, and loyalty programs such as our FREE SPIRIT affinity credit card program and $9 Fare Club. Non-ticket revenues also include revenues derived from services not directly related to providing transportation such as the sale of advertising to third parties on our website and on board our aircraft.

Substantially all of our revenues are denominated in U.S. dollars. Passenger revenues are recognized once the related flight departs. Accordingly, the value of tickets sold in advance of travel is included under our current liabilities as “air traffic liability,” or ATL, until the related air travel is provided. Non-ticket revenues are generally recognized at the time the ancillary products are purchased or ancillary services are provided. Non-ticket revenues also include revenues from our subscription-based $9 Fare Club, which we recognize on a straight-line basis over 12 months. Revenue is generated from the FREE SPIRIT credit card affinity program through the sale of FREE SPIRIT miles, card acquisitions, ongoing use of the FREE SPIRIT credit cards, milestone payments in connection with the achievement of specific usage and user volumes, and renewals, which we currently recognize in accordance with the criteria as set forth in Accounting Standards Update ASU No. 2009-13. Please see “—Critical Accounting Policies and Estimates—Frequent Flier Program”.

We recognize revenues net of certain taxes and airport passenger fees, which are collected by us on behalf of airports and governmental agencies and remitted to the applicable governmental entity or airport on a periodic basis. These taxes and fees include U.S. federal transportation taxes, federal security charges, airport passenger facility charges, and foreign arrival and departure taxes. These items are collected from customers at the time they purchase their tickets, but are not included in our

revenues. We record a liability upon collection from the customer and relieve the liability when payments are remitted to the applicable governmental agency or airport.

Our Operating Expenses

Our operating expenses consist of the following line items.

Aircraft Fuel. Aircraft fuel expense is our single largest operating expense. It includes the cost of jet fuel, related federal taxes, fueling into-plane fees and transportation fees. It also includes realized and unrealized gains and losses arising from any fuel price hedging activity.

Salaries, Wages and Benefits. Salaries, wages and benefits expense includes the salaries, hourly wages, bonuses and equity compensation paid to employees for their services, as well as the related expenses associated with employee benefit plans and employer payroll taxes.

Aircraft Rent. Aircraft rent expense consists of monthly lease rents for aircraft and spare engines under the terms of the related operating leases and is recognized on a straight-line basis. Aircraft rent expense also includes that portion of maintenance reserves, also referred to as supplemental rent, paid to aircraft lessors in advance of the performance of major maintenance activities that is not probable of being reimbursed to us by the lessor. To the extent we had any return condition obligations which we believe are probable, those would be considered contingent rent and would be included within aircraft rent expense. Aircraft rent expense is net of the amortization of gains and losses on sale and leaseback transactions on our flight equipment. Presently, all of our aircraft and spare engines are financed under operating leases.

Landing Fees and Other Rents. Landing fees and other rents include both fixed and variable facilities expenses, such as the fees charged by airports for the use or lease of airport facilities, overfly fees paid to other countries and the monthly rent paid for our headquarters facility.

Distribution. Distribution expense includes all of our direct costs to sell, including the cost of web support, our third-party call center, travel agent commissions and related GDS fees, and credit card transaction fees, associated with the sale of our tickets and other products and services.

Maintenance, Materials and Repairs. Maintenance, materials and repairs expense includes all parts, materials, repairs and fees for repairs performed by third-party vendors directly required to maintain our fleet. It excludes direct labor cost related to our own mechanics, which is included under salaries, wages and benefits. It also excludes the amortization of heavy maintenance expenses, which we defer under the deferral method of accounting and amortize on a straight-line or usage basis until the next estimated overhaul event.

Depreciation and Amortization. Depreciation and amortization expense includes the depreciation of fixed assets we own and leasehold improvements. It also includes the amortization of heavy maintenance expenses we defer under the deferral method of accounting for heavy maintenance events and recognize into expense on a straight-line or usage basis until the next overhaul event.

Loss on Disposal of Assets. Loss on disposal of assets includes the net losses on the disposal of our fixed assets, including losses on sale and leaseback transactions.

Other Operating Expenses. Other operating expenses include airport operations expense and fees charged by third-party vendors for ground handling services and food and liquor supply service expenses, passenger re-accommodation expense, the cost of passenger liability and aircraft hull insurance, all other insurance policies except for employee health insurance, travel and training expenses for crews and ground personnel, professional fees, personal property taxes and all other administrative and operational overhead expenses. No individual item included in this category represented more than 5% of our total operating expenses.

Special Charges (Credits). Special charges (credits) include termination costs, restructuring costs, secondary offering costs, and the gain on the sale of take-off and landing slots.

In June 2012, we transferred four permanent air carrier slots at Ronald Reagan National Airport (“DCA”) to another airline for $9.1 million. Due to FAA regulations, the gain of $9.1 million was fully deferred at the time of the sale. The Company recognized the $9.1 million gain within special charges (credits) in the third quarter of 2012, the period in which the FAA operating restriction lapsed and written confirmation of the slot transfer was received by the buyer from the FAA.

On July 31, 2012, certain stockholders affiliated with Oaktree Capital Management ("Oaktree") sold an aggregate of 9,394,927 shares of common stock in an underwritten public offering. The Company incurred a total of $0.7 million in costs

during the year ended December 31, 2012 related to this offering. Upon completion of this secondary offering, investment funds affiliated with Oaktree owned no shares of our common stock.

Previously, on January 25, 2012, certain stockholders of the Company, including affiliates of Oaktree and Indigo Partners, LLC ("Indigo") and certain members of the Company's executive team, sold an aggregate of 12,650,000 shares of common stock in an underwritten public offering. The Company incurred a total of $1.3 million in costs between 2011 and 2012 related to this secondary offering, offset by reimbursements from certain selling shareholders of $0.6 million in accordance with the Fourth Amendment to the Second Amended and Restated Investor Rights Agreement.

The Company did not receive any proceeds from either of these secondary offerings.

In the second quarter of 2011, we incurred $2.3 million of termination costs in connection with the IPO comprised of amounts paid to Indigo to terminate its professional services agreement with us and fees paid to three individual, unaffiliated holders of our subordinated notes.

Our Other Expense (Income)

Interest Expense. Paid-in-kind interest on notes due to related parties and preferred stock dividends due to related parties account, on average, for over 80% of interest expense incurred for the years 2011 and 2010. Non-related party interest expense accounted for the remainder of interest expense in these periods. All of the notes and preferred stock were repaid or redeemed, or exchanged for common stock, in connection with the 2011 Recapitalization. Interest expense in 2012 primarily relates to interest on pre-delivery deposits.

Capitalized Interest. Capitalized interest represents interest cost to finance purchase deposits for future aircraft and the opportunity cost (interest) incurred during the acquisition period of an aircraft that theoretically could have been avoided had we not made PDPs for that aircraft. These amounts are recorded as part of the cost of the aircraft upon delivery. Capitalization of interest ceases when the asset is ready for service.

Our Income Taxes

We account for income taxes using the liability method. We record a valuation allowance to reduce the deferred tax assets reported if, based on the weight of the evidence, it is more likely than not that some portion or all of the deferred tax assets will not be realized. Deferred taxes are recorded based on differences between the financial statement basis and tax basis of assets and liabilities and available tax loss and credit carryforwards. In assessing the realizability of the deferred tax assets, we consider whether it is more likely than not that some or all of the deferred tax assets will be realized. In evaluating the ability to utilize our deferred tax assets, we consider all available evidence, both positive and negative, in determining future taxable income on a jurisdiction by jurisdiction basis.

Immediately prior to the IPO, we entered into the Tax Receivable Agreement and thereby distributed to the Pre-IPO Stockholders the right to receive such stockholders’ pro rata share of the future payments to be made by us under the Tax Receivable Agreement. Under the Tax Receivable Agreement, we are obligated to pay to the Pre-IPO Stockholders an amount equal to 90% of the cash savings in federal income tax realized by us by virtue of our future use of the federal net operating loss, deferred interest deductions and alternative minimum tax credits held by us as of March 31, 2011, which we refer to as the Pre-IPO NOL. “Deferred interest deductions” means interest deductions that have accrued as of March 31, 2011, but have been deferred under rules applicable to related party debt. Cash tax savings generally will be computed by comparing our actual federal income tax liability to the amount of such taxes that we would have been required to pay had such Pre-IPO NOLs not been available to us. Upon consummation of the IPO and execution of the TRA, the Company recorded a liability with an offsetting reduction to additional paid in capital.

The term of the TRA will continue until the first to occur of (a) the full payment of all amounts required under the agreement with respect to utilization or expiration of all of the Pre-IPO NOLs, (b) the end of the taxable year including the tenth anniversary of the IPO or (c) a change in control of the Company. The amount and timing of payments under the TRA will depend upon a number of factors, including, but not limited to, the amount and timing of taxable income generated in the future and any future limitations that may be imposed on the Company's ability to use the Pre-IPO NOLs. The Company paid $27.2 million, or 90% of the tax savings realized from the utilization of NOLs in 2011, including $0.3 million of applicable interest in 2012 related to the TRA. As of December 31, 2012 an estimated remaining cash benefit of $8.0 million is expected to be paid in 2013 to our Pre-IPO Stockholders under the terms of the TRA.

Trends and Uncertainties Affecting Our Business

We believe our operating and business performance is driven by various factors that affect airlines and their markets, trends affecting the broader travel industry, and trends affecting the specific markets and customer base that we target. The

following key factors may affect our future performance.

Competition. The airline industry is highly competitive. The principal competitive factors in the airline industry are fare pricing, total price, flight schedules, aircraft type, passenger amenities, number of routes served from a city, customer service, safety record and reputation, code-sharing relationships, and frequent flier programs and redemption opportunities. Price competition occurs on a market-by-market basis through price discounts, changes in pricing structures, fare matching, target promotions and frequent flier initiatives. Airlines typically use discount fares and other promotions to stimulate traffic during normally slower travel periods to generate cash flow and to maximize unit revenue. The prevalence of discount fares can be particularly acute when a competitor has excess capacity that it is under financial pressure to sell.

Seasonality and Volatility. Our results of operations for any interim period are not necessarily indicative of those for the entire year because the air transportation business is subject to significant seasonal fluctuations. We generally expect demand to be greater in the second and third quarters compared to the rest of the year. The air transportation business is also volatile and highly affected by economic cycles and trends. Consumer confidence and discretionary spending, fear of terrorism or war, weakening economic conditions, fare initiatives, fluctuations in fuel prices, labor actions, changed in governmental regulations on taxes and fees, weather and other factors have resulted in significant fluctuations in revenues and results of operations in the past. We believe demand for business travel historically has been more sensitive to economic pressures than demand for low-price travel. Finally, a significant portion of our operations are concentrated in markets such as South Florida, the Caribbean, Latin America and the Northeast and northern Midwest regions of the United States, which are particularly vulnerable to weather, airport traffic constraints and other delays.

Aircraft Fuel. Fuel costs represent the single largest operating expense for most airlines, including ours. Fuel costs have been subject to wide price fluctuations in recent years. Fuel availability and pricing are also subject to refining capacity, periods of market surplus and shortage, and demand for heating oil, gasoline and other petroleum products, as well as meteorological, economic and political factors and events occurring throughout the world, which we can neither control nor accurately predict. We source a significant portion of our fuel from refining resources located in the southeast United States, particularly facilities adjacent to the Gulf of Mexico. Gulf Coast fuel is subject to volatility and supply disruptions, particularly in hurricane season when refinery shutdowns have occurred in recent years, or when the threat of weather-related disruptions has caused Gulf Coast fuel prices to spike above other regional sources. From time to time, we use fuel hedges using NYMEX WTI and U.S. Gulf Coast jet fuel collars as the underlying commodity to attempt to mitigate price volatility. Additionally, during peak hurricane season (August through October), we may enter into jet fuel swaps to protect the refining price risk between the price of crude oil and the price of refined jet fuel. Historically, we have protected approximately 70% of our forecasted fuel requirements during peak hurricane season using jet fuel swaps. Our fuel hedging practices are dependent upon many factors, including our assessment of market conditions for fuel, our access to the capital necessary to support margin requirements, the pricing of hedges and other derivative products in the market and applicable regulatory policies. As of December 31, 2012, the Company had agreements in place to protect $7.8 million gallons or approximately 5% of its 2013 anticipated fuel consumption. As of December 31, 2012, we purchased all of our aircraft fuel under a single fuel service contract. The cost and future availability of jet fuel cannot be predicted with any degree of certainty.

Labor. The airline industry is heavily unionized. The wages, benefits and work rules of unionized airline industry employees are determined by collective bargaining agreements, or CBAs. Relations between air carriers and labor unions in the United States are governed by the RLA. Under the RLA, CBAs generally contain “amendable dates” rather than expiration dates, and the RLA requires that a carrier maintain the existing terms and conditions of employment following the amendable date through a multi-stage and usually lengthy series of bargaining processes overseen by the NMB. This process continues until either the parties have reached agreement on a new CBA, or the parties have been released to “self-help” by the NMB. In most circumstances, the RLA prohibits strikes; however, after release by the NMB, carriers and unions are free to engage in self-help measures such as strikes and lockouts.

We have three union-represented employee groups comprising approximately 54% of our employees at December 31, 2012. Our pilots are represented by the Airline Pilots Association, International, or ALPA, our flight attendants are represented by the Association of Flight Attendants, or AFA-CWA, and our flight dispatchers are represented by the Transport Workers Union of America, or TWU. Conflicts between airlines and their unions can lead to work slowdowns or stoppages. In June 2010, we experienced a five-day strike by our pilots, which caused us to shut down our flight operations. The strike ended as a result of our reaching a tentative agreement under a Return to Work Agreement and a full flight schedule was resumed on June 18, 2010. On August 1, 2010, we entered into a five-year collective bargaining agreement. We believe the five-year term is valuable in providing stability to our labor costs, and that the other terms will also provide us with competitive pilot labor costs compared to other U.S.-based low-cost carriers.

In addition, our CBA with our flight attendants became amendable under the RLA in 2007, and we are currently engaged in negotiations with the AFA-CWA. The outcome of our collective bargaining negotiations cannot presently be determined and

the terms and conditions of our future CBAs may be affected by the results of collective bargaining negotiations at other airlines that may have a greater ability to bear higher costs under their business models. If we are unable to reach agreement with any of our unionized work groups in current or future negotiations regarding the terms of their CBAs, we may be subject to work interruptions or stoppages, such as the strike by our pilots in June 2010. A strike or other significant labor dispute with our unionized employees is likely to adversely affect our ability to conduct business.

Maintenance Expense. Maintenance expense grew through 2012, 2011 and 2010 mainly as a result of the increasing age of our fleet (approximately 4.6 years on average at December 31, 2012) and growing fleet. As the fleet ages, we expect that maintenance costs will increase in absolute terms. The amount of total maintenance costs and related amortization of heavy maintenance expense is subject to many variables such as future utilization rates, average stage length, the size and makeup of the fleet in future periods and the level of unscheduled maintenance events and their actual costs. Accordingly, we cannot reliably quantify future maintenance expenses for any significant period of time. However, we believe, based on our scheduled maintenance events, current maintenance expense and maintenance-related amortization expense in 2013 will be approximately $90 million.

As a result of a significant portion of our fleet being acquired over a relatively short period of time, significant maintenance scheduled on each of our planes will occur at roughly the same time, meaning we will incur our most expensive scheduled maintenance obligations across our current fleet around the same time. These more significant maintenance activities will result in out-of-service periods during which our aircraft will be dedicated to maintenance activities and unavailable to fly revenue service. In addition, management expects that the final heavy maintenance events will be amortized over the remaining lease term rather than until the next estimated heavy maintenance event, because we account for heavy maintenance under the deferral method. Please see “—Critical Accounting Policies and Estimates—Aircraft Maintenance, Materials, Repair Costs and Related Heavy Maintenance Amortization.” This will result in significantly higher depreciation and amortization expense related to heavy maintenance.

Maintenance Reserve Obligations. The terms of some of our aircraft lease agreements require us to pay supplemental rent, also known as maintenance reserves, to the lessor in advance of and as collateral for the performance of major maintenance events, resulting in our recording significant prepaid deposits on our balance sheet. As a result, the cash costs of scheduled major maintenance events are paid well in advance of the recognition of the maintenance event in our results of operations. Please see “—Critical Accounting Policies and Estimates—Aircraft Maintenance, Materials, Repair Costs and Related Heavy Maintenance Amortization” and “—Maintenance Reserves.”

Critical Accounting Policies and Estimates

The following discussion and analysis of our financial condition and results of operations is based on our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amount of assets and liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities at the date of our financial statements. Note 1 to our financial statements provides a detailed discussion of our significant accounting policies.

Critical accounting policies are defined as those policies that reflect significant judgments or estimates about matters that are both inherently uncertain and material to our financial condition or results of operations.

Revenue Recognition. Revenues from tickets sold are initially deferred as ATL. Passenger revenues are recognized when transportation is provided. An unused non-refundable ticket expires at the date of scheduled travel and is recognized as revenue for the expired ticket value at the date of scheduled travel.

Our most significant non-ticket revenues include revenues generated from air travel-related services paid for baggage, bookings through our call center or third-party vendors, advance seat selection, itinerary changes and loyalty programs, and are recognized at the time products are purchased or ancillary services are provided. These revenues also include commissions from the sales of hotel rooms, trip insurance and rental cars recognized at the time the service is rendered.

Customers may elect to change their itinerary prior to the date of departure. A service charge is assessed and recognized on the date the change is initiated and is deducted from the face value of the original purchase price of the ticket, and the original ticket becomes invalid. The amount remaining after deducting the service charge is called a credit shell which expires 60 days from the date the credit shell is created and can be used towards the purchase of a new ticket and the Company’s other service offerings. The amount of credits expected to expire is recognized as revenue upon issuance of the credit and is estimated based on historical experience. Estimating the amount of credits that will go unused involves some level of subjectivity and judgment.

Non-ticket revenues include revenues from our subscription-based $9 Fare Club, recognized on a straight-line basis over

12 months. Revenues generated from the sale of FREE SPIRIT miles and credit card renewals are currently recognized on a straight-line basis over 16 months based on expected customer usage of miles. We make assumptions on the future use of customer miles based on historical customer behavior. To the extent that customer behavior changes as a result of, among other factors, economic conditions, perception of travel, and the number of miles to earn awards, a corresponding adjustment would be made to the period in which we recognize revenue generated from the FREE SPIRIT miles and credit card renewals, resulting in either a smaller or larger liability. Also included in non-ticket revenues are milestone payments in connection with the achievement of specific usage and user volumes, which we recognize when received from the FREE SPIRIT credit card provider.

Frequent Flier Program. We accrue for mileage credits earned through travel, including mileage credits for members with an insufficient number of mileage credits to earn an award, under our FREE SPIRIT program based on the estimated incremental cost of providing free travel for credits that are expected to be redeemed. Incremental costs include fuel, insurance, security, ticketing and facility charges reduced by an estimate of amounts required to be paid by the passenger when redeeming the award.

We also sell mileage credits to companies participating in the FREE SPIRIT program (or affinity card program). Under our original affinity card program, funds received from the sale of mileage credits were accounted for as a multiple-element arrangement and allocated to a marketing component and a transportation component (mileage credits) using the residual method. The fair value of the transportation component was deferred and recognized ratably as passenger revenue over the estimated period the transportation was expected to be provided. The difference between the funds received and the fair value of the transportation component was recognized in non-ticket revenue at the time of sale as non-ticket marketing revenue. The marketing component represented our compensation for, among many items, use of our trademark, customer lists and placement of marketing materials to encourage application for credit cards. Because there were no undelivered elements other than the mileage credits, we recorded the revenue from the marketing component when funds were received. We also received bonuses from companies participating in the FREE SPIRIT program that are driven by the volume of the usage of our co-branded credit cards. We recognized these bonuses as non-ticket revenue when payment is received (milestone method) as the milestones were substantive.

During the fourth quarter of 2010, the Company determined not to renew its agreement with the administrator of the FREE SPIRIT affinity credit card program at the scheduled expiration in February 2011. We entered into a new affinity card program that became effective April 1, 2011 for the marketing of a co-branded Spirit credit card and the delivery of award miles over a five-year period. At the inception of the arrangement, we evaluated all deliverables in the arrangement to determine whether they represent separate units of accounting. We determined the arrangement had three separate units of accounting: (i) travel miles to be awarded, (ii) licensing of brand and access to member lists, and (iii) advertising and marketing efforts. At inception of the arrangement, we established the relative selling price for all deliverables that qualified for separation, as arrangement consideration should be allocated based on relative selling price. The manner in which the selling price was established was based on the applicable hierarchy of evidence. Total arrangement consideration was then allocated to each deliverable on the basis of the deliverable's relative selling price. In considering the hierarchy of evidence, we first determined whether vendor-specific objective evidence of selling price or third-party evidence of selling price existed. We determined that neither vendor-specific objective evidence of selling price nor third-party evidence existed due to the uniqueness of our program. As such, we developed our best estimate of the selling price for all deliverables. For the selling price of travel, we considered a number of entity-specific factors including the number of miles needed to redeem an award, average fare of comparable segments, breakage, restrictions, and other charges. For licensing of brand and access to member lists, we considered both market-specific factors and entity-specific factors, including general profit margins realized in the marketplace/industry, brand power, market royalty rates, and size of customer base. For the advertising and marketing element, we considered market-specific factors and entity-specific factors including, our internal costs (and fluctuations of costs) of providing services, volume of marketing efforts, and overall advertising plan. Consideration allocated based on the relative selling price to both brand licensing and advertising elements is recognized as revenue when earned and recorded in non-ticket revenue. Consideration allocated to award miles is deferred and recognized ratably as passenger revenue over the estimated period the transportation is expected to be provided which is currently estimated at 16 months. We used entity-specific assumptions coupled with the various judgments necessary to determine the selling price of a deliverable in accordance with the required selling price hierarchy. Changes in these assumptions (e.g., cost of fare, number of miles to redeem awards, marketing plan, and approval rate of credit cards) could result in changes in the estimated selling prices. Determining the frequency to reassess selling price for individual deliverables requires significant judgment. For additional information, please see “Notes to Financial Statements—1. Summary of Significant Accounting Policies—Frequent Flier Program”.

Aircraft Maintenance, Materials, Repair Costs and Related Heavy Maintenance Amortization. We account for heavy maintenance under the deferral method. Under the deferral method the cost of heavy maintenance is capitalized and amortized as a component of depreciation and amortization expense until the earlier of the next estimated heavy maintenance event or the aircraft's return at the end of the lease term. Amortization of engine and aircraft overhaul costs was $9.1 million, $2.6 million,

and $1.3 million for the years ended December 31, 2012, 2011, and 2010, respectively. If heavy maintenance costs were amortized within maintenance, material and repairs expense in the statement of operations, our maintenance, material and repairs expense would have been $58.6 million, $38.1 million, and $29.5 million for the years ended December 31, 2012, 2011, and 2010, respectively. During the years ended December 31, 2012, 2011, and 2010, we capitalized $61.6 million, $22.1 million, and $5.2 million of costs for heavy maintenance, respectively. The timing of the next heavy maintenance event is estimated based on assumptions including estimated usage, FAA-mandated maintenance intervals and average removal times as suggested by the manufacturer. These assumptions may change based on changes in our utilization of our aircraft, changes in government regulations and suggested manufacturer maintenance intervals. In addition, these assumptions can be affected by unplanned incidents that could damage an airframe, engine, or major component to a level that would require a heavy maintenance event prior to a scheduled maintenance event. To the extent our planned usage increases, the estimated life would decrease before the next maintenance event, resulting in additional expense over a shorter period. Heavy maintenance events are our 6-year and 12-year airframe checks (HMV4 and HMV8, respectively), engine overhauls, and overhauls to major components. Certain maintenance functions are outsourced under contracts that require payment based on a performance measure such as flight hours. Costs incurred for maintenance and repair under flight hour maintenance contracts, where labor and materials price risks have been transferred to the service provider, are accrued based on contractual payment terms. Routine cost for maintaining the airframes and engines and line maintenance are charged to maintenance, materials and repairs expense as performed.

Maintenance Reserves. Some of our master lease agreements provide that we pay maintenance reserves to aircraft lessors to be held as collateral in advance of our performance of major maintenance activities. These lease agreements provide that maintenance reserves are reimbursable to us upon completion of the maintenance event in an amount equal to the lesser of (1) the amount of the maintenance reserve held by the lessor associated with the specific maintenance event or (2) the qualifying costs related to the specific maintenance event. Substantially all of these maintenance reserve payments are calculated based on a utilization measure, such as flight hours or cycles, and are used solely to collateralize the lessor for maintenance time run off the aircraft until the completion of the maintenance of the aircraft. We paid $31.6 million, $38.3 million and $35.7 million in maintenance reserves, net of reimbursement, to our lessors for the years ended December 31, 2012, 2011, and 2010, respectively.

At lease inception and at each balance sheet date, we assess whether the maintenance reserve payments required by the master lease agreements are substantively and contractually related to the maintenance of the leased asset. Maintenance reserve payments that are substantively and contractually related to the maintenance of the leased asset are accounted for as maintenance deposits. Maintenance deposits expected to be recovered from lessors are reflected as prepaid maintenance deposits in the accompanying balance sheets. When it is not probable we will recover amounts currently on deposit with a lessor, such amounts are expensed as supplemental rent. Because we we are required to pay maintenance reserves for our operating leased aircraft, and we chose to apply the deferral method for maintenance accounting, management expects that the final heavy maintenance events will be amortized over the remaining lease term rather than over the next estimated heavy maintenance event. As a result, our maintenance costs in the last few years of leases could be significantly in excess of the costs in earlier periods. In addition these late periods could include additional costs from unrecoverable maintenance reserve payments required in the late years of the lease. We expensed $2.0 million, $1.5 million, and $0.0 million of maintenance reserves as supplemental rent during 2012, 2011, and 2010, respectively.

As of December 31, 2012, 2011, and 2010, we had prepaid maintenance deposits of $198.5 million, $168.8 million and $132.0 million, respectively, on our balance sheets. We have concluded that these prepaid maintenance deposits are probable of recovery primarily due to the rate differential between the maintenance reserve payments and the expected cost for the related next maintenance event that the reserves serve to collateralize.

These master lease agreements also provide that most maintenance reserves held by the lessor at the expiration of the lease are nonrefundable to us and will be retained by the lessor. Consequently, we have determined that any usage-based maintenance reserve payments after the last major maintenance event are not substantively related to the maintenance of the leased asset and therefore are accounted for as contingent rent. We accrue contingent rent beginning when it becomes probable and reasonably estimable we will incur such nonrefundable maintenance reserve payments. We make certain assumptions at the inception of the lease and at each balance sheet date to determine the recoverability of maintenance deposits. These assumptions are based on various factors such as the estimated time between the maintenance events, the cost of future maintenance events and the number of flight hours the aircraft is estimated to be utilized before it is returned to the lessor. Maintenance reserves held by lessors that are refundable to us at the expiration of the lease are accounted for as prepaid maintenance deposits on the balance sheet when they are paid.

RESULTS OF OPERATIONS

In 2012, we achieved a 13.2% operating margin, down by 0.3 points compared to 2011, mostly driven by approximately

$25 million in lost revenues from the impact of Hurricane Sandy in the fourth quarter of 2012. In 2012, we generated pre-tax earnings of $174.6 million and net earnings of $108.5 million on operating revenues of $1,318.4 million. For 2011, we generated pre-tax earnings of $122.8 million and net earnings of $76.4 million on operating revenues of 1,071.2 million and achieved a 13.5% operating margin. Cash and cash equivalents increased by 73.5 million in 2012 compared to the prior year, and as of December 31, 2012, we had cash and cash equivalents of $416.8 million.

The increase in operating income in 2012 over 2011 of $29.6 million, or 20.5%, is mainly due to a 23.1% increase in revenue partially offset by increased fuel and other expenses. Revenue increased year over year as a result of a 21.3% increase in capacity and a 1.9% improvement in average yield. Fuel costs increased by $83.7 million during 2012 compared to 2011, primarily driven by an 18.1% increase in consumption. Operating expenses increased primarily due to our growth in capacity resulting from the addition of eight aircraft to our fleet and our route network expansion.

In 2011, we improved our liquidity position with the completion of an IPO in June, whereby we retained $150.0 million of net proceeds, after paying off debt, fees and costs associated with the offering. We recorded operating income in 2011 of $144.4 million on $1,071.2 million of operating revenues. Capacity growth and increased load factor in 2011 drove the increase in revenue over 2010 and was partially offset by increased fuel prices and increases in various other operating costs.

Net income for 2010 of $72.5 million includes a $52.3 million net tax benefit primarily due to the release of a valuation allowance resulting in a deferred tax benefit of $52.8 million in 2010. Absent the release of the valuation allowance and corresponding tax benefit, our net income would have been $19.7 million for 2010. In 2010, we recorded operating income of $68.9 million on $781.3 million of operating revenues. The results of operations for 2010 were adversely affected by an increase in fuel prices and the effects of our June 2010 pilot strike.

Total revenue per passenger flight segment	$	126.50	0.6%	$	125.76	11.9%	$	112.39

Non-ticket revenues comprise 40.6% of our total revenue for fiscal 2012 due to the effect of unbundling our fares and the introduction of new services beyond the sale of a ticket for transportation.

2012 compared to 2011

Operating revenue increased by $247.2 million, or 23.1%, to $1,318.4 million in 2012 compared to the prior year period as we increased traffic by 20.7% and improved our yield by 1.9% to 13.64 cents.

Our results for the year ended December 31, 2012 were driven by growing capacity 21.3% compared to the prior year period while maintaining a high load factor of 85.2% and a network reorientation in mid-2011 that added capacity in Dallas-Fort Worth, Chicago and Las Vegas. In October 2012, we canceled 136 flights, or 19.9 million available seat miles, as a result of adverse weather conditions and airport closures in connection with Hurricane Sandy. The negative impact of the storm on 2012 revenue was approximately $25 million. We generated greater demand in 2012 by lowering our average ticket revenue per passenger flight segment to $75.11, or by 7.2% compared to the prior year period, while increasing our non-ticket revenue per passenger flight segment from $44.79 to $51.39, a 14.7% increase compared to the prior year period. Total revenue per passenger flight segment increased 0.6% from $125.76 in 2011 to $126.50 in 2012.

We experienced a 40.4% increase in non-ticket revenues in 2012 compared to 2011, reflecting the continued development and optimization of ancillary revenues and a 22.4% increase in passenger flight segments. During the fourth quarter of 2011 and continuing into 2012, we further standardized our passenger usage fee across all markets and fare classes, which drove much of the increases in non-ticket revenue in 2012 compared to 2011. Non-ticket revenue represented 40.6% of total revenue in the year ended December 31, 2012 compared to 35.6% in the same period of 2011.

2011 compared to 2010

Operating revenues increased by $289.9 million, or 37.1%, to $1,071.2 million in 2011 compared to $781.3 million in 2010. Our capacity in terms of ASMs increased 15.2% during 2011 compared to 2010, primarily driven by the addition of Airbus 320 aircraft, five of which were delivered during 2011, and the full-year effect of our four 2010 deliveries. Our traffic as measured in terms of RPMs increased by 20.1% during 2011 compared to 2010. Our aircraft operated an average of 12.7 hours daily with 85.6% of the seats full during 2011 compared to an average of 12.8 hours daily with 82.1% of the seats full during 2010.

Within operating revenues, passenger ticket revenue increased by 28.2% to $689.7 million in 2011 compared to $538.0 million in 2010. This increase was driven primarily by a 22.5% increase in passenger segments in 2011 compared to 2010.

Non-ticket revenues increased by $138.2 million in 2011 compared to 2010, a 56.8% increase primarily driven by the 22.5% increase in passenger flight segments and price enhancements on non-ticket services. During the first quarter of 2011, we reduced the weight threshold for overweight baggage from 50 pounds to 40 pounds and increased the amount charged to customers for modifying or canceling their reservations. During the second quarter of 2011, we increased bag rates purchased at check-in on the web, the airport, and at the kiosk. During the second half of 2011, we began our efforts to standardize our passenger usage fee across all markets and fare classes. As a result of experienced continued growth in revenue from many previously adopted non-ticket revenue initiatives, our non-ticket revenue per passenger flight segment increased 28.0% to $44.79 for 2011 from $35.00 for 2010.

Effective April 1, 2011, we entered into a new five-year affinity card program for the issuance of our FREE SPIRIT credit cards with a new administrator. During 2010, we determined not to renew our agreement with the former administrator of our FREE SPIRIT affinity credit card program at the scheduled expiration in February 2011. In connection with that non-renewal, we entered into an agreement with the former administrator regarding the transition of the program to the new provider and the remittance to us of compensation due to us for card members obtained through our marketing services in the amount of $5.0 million, of which $0.4 million was recognized in the first quarter of 2011 and $4.6 million was recognized in the fourth quarter of 2010.

Operating Expenses

Since adopting our ultra low-cost model, we have continuously sought to reduce our unit operating costs and have created what we believe is one of the lowest cost structures in our industry in the Americas. The table below presents our operating expenses, as a percentage of operating revenue for the last three years, as well as unit operating costs (CASM).

Includes special charges (credits) of $(8.5) million ((0.07) cents per ASM) in 2012, $3.2 million (0.03 cents per ASM) in 2011 and $0.6 million (less than 0.01 cents per ASM) in 2010. Special charges (credits) for 2012 primarily include a $9.1 million gain related to the sale of four permanent air carrier slots at Ronald Reagan National Airport (DCA), offset by $0.6 million in secondary offering costs. Special charges (credits) for 2011 include $2.3 million of termination costs in connection with the IPO comprised of amounts paid to Indigo Partners, LLC to terminate its professional services agreement with us and fees paid to three individual, unaffiliated holders of our subordinated notes and in the fourth quarter include legal, accounting, printing, and filing fees connected with the secondary offering which was consummated on January 25, 2012. Special charges (credits) for 2010 include exit facility costs associated with amounts relating to the sale of previously-expensed MD-80 parts and exit facility costs associated with moving our Detroit, Michigan maintenance activities to Fort Lauderdale, Florida. Please see “—Our Operating Expenses—Special Charges (Credits).”

2012 compared to 2011

Operating expense increased by $217.6 million for 2012 compared to the prior year period mostly due to increases in fuel and labor costs, which were primarily driven by our 21.3% capacity growth, in addition to increases in other operating costs.

Our adjusted CASM ex fuel for 2012 increased by 4.9% as compared to the same period in 2011. During 2012, we incurred higher other operating expenses driven by higher costs associated with passenger re-accommodations related to slightly higher flight cancellations. Additionally, overall increased rates at the airports resulted in increased variable operating costs such as ground handling expenses and travel and lodging expense. During 2012, we also incurred an increase in maintenance costs related to our seat maintenance program and an increase in deferred heavy aircraft maintenance events, which in turn resulted in higher heavy maintenance amortization expense. Our average stage length for 2012 decreased by 1.3%, contributing to the year-over-year increase in adjusted CASM ex fuel.

Aircraft fuel expenses includes both into-plane expense (as defined below) plus the effect of mark-to-market adjustments to our portfolio of derivative instruments, which is a component of aircraft fuel expenses. Into-plane fuel expense is defined as the price that we generally pay at the airport, or the “into-plane” price, including taxes and fees. Into-plane fuel prices are affected by world oil prices and refining costs, which can vary by region in the United States and the other countries where we operate. Both fuel consumption and prices increased during 2012. Into-plane fuel expense approximates cash paid to the supplier and does not reflect the effect of our fuel derivatives. Because our fuel derivative contracts do not qualify for hedge accounting, we recognize both realized and unrealized changes in the fair value of our derivatives when they occur as a component of aircraft fuel expense.

We evaluate economic fuel expense, which we define as into-plane fuel expense excluding the cash we receive from or pay to counterparties for hedges that we settle during the relevant period, including hedges that we terminate early during the period. The key difference between aircraft fuel expense and economic fuel expense is the timing of gain or loss recognition on our hedge portfolio. When we refer to economic fuel expense, we include net settlement gains or losses only when they are realized through a cash payment from our derivative contract counterparties for those contracts that were settled during the period. We believe this is the best measure of the effect that fuel prices are currently having on our business because it most closely approximates the net cash outflow associated with purchasing fuel for our operations. Accordingly, many industry analysts also evaluate airline results using this measure, and it is frequently used in our internal management reporting.

Aircraft fuel expense increased from $388.0 million in 2011 to $471.8 million in 2012, representing 41.2% of our total operating expenses for that 2012 period. The increase was primarily due to an 18.1% increase in fuel gallons consumed as well as a 3.8% increase in fuel prices.

The difference between aircraft fuel expense and economic fuel expense and the elements of the changes are illustrated in the following table:



	Year Ended December 31,					Percent Change
	2012		2011			Percent Change
	(in thousands, except per-gallon amounts)
Into-plane fuel expense	$	471,542	$	392,278		20.2	%
Cash received from settled derivatives, net of cash settlements paid	175		(7,436		)	(102.4	)%
Economic fuel expense	471,717		384,842			22.6	%
Impact on fuel expense from unrealized (gains) and losses arising from mark-to-market adjustments to our outstanding fuel derivatives	46		3,204			(98.6	)%
Aircraft fuel expense (per Statement of Operations)	$	471,763	$	388,046		21.6	%
Fuel gallons consumed	142,991		121,030			18.1	%
Economic fuel cost per gallon	$	3.30	$	3.18		3.8	%
Into-plane fuel cost per gallon	$	3.30	$	3.24		1.9	%

Fuel gallons consumed increased 18.1% as a result of increased operations, as evidenced by an 18.8% increase in block hours. Our average daily aircraft utilization in 2012 increased slightly compared to the prior year period. We estimate the fuel savings related to the 136 flights cancellations due to Hurricane Sandy were approximately $0.6 million.

Total net loss recognized for hedges that settled during 2012 was $0.2 million, compared to a net gain of $7.4 million in the prior year period. These amounts represent the net cash paid (received) for the settlement of hedges.

Labor costs in 2012 increased by $37.2 million, or 20.5%, compared to 2011, primarily driven by a 22.4% increase in our pilot and flight attendant workforce as we increased our fleet size by 21.6%, or eight aircraft, during 2012. During 2012, we incurred an incremental $3.8 million of share-based compensation recorded within salaries, wages and benefits, driven primarily by the commencement of the Performance Share Awards program in 2012.

During 2012, aircraft rent increased $27.1 million, or 23.3%, mainly due to the delivery of eight Airbus A320 aircraft subsequent to the fourth quarter of 2011. All aircraft were financed through operating leases. The increase of aircraft rent expense on a per-ASM basis is primarily due to the fact that we incurred $2.5 million of additional aircraft rent during 2012 related to a short-term lease agreement with a third-party provider (wet-leased aircraft) to maintain desired capacity during the summer months.

Landing fees and other rents for 2012 increased by $15.6 million, or 29.5%, compared to 2011 primarily due to a 19.9% increase in departures. On a per-ASM basis, the increase in landing fees and other rents of 7.1% during 2012 as compared to the prior year period is due to increased volume at higher-cost airports, including the addition of six new airports served in 2012, which on average are higher-cost airports than the system average.

The increase in distribution expense of $5.3 million, or 10.4%, in 2012 compared to 2011 was primarily due to increased volume and an increase of approximately 4.1 percentage points year-over-year in the percentage of sales from third-party travel agents, which are more expensive than sales directly through our website. This shift in distribution mix did not materially affect operating income because the revenues received from sales through third-party travel agents are designed to at least offset the associated incremental costs. The decrease on a per-unit basis is primarily due to a decrease of approximately 14% in credit card fee rates period over period.

The following table shows our distribution channel usage:



	Year Ended December 31,
	2012		2011		Change
Website	64.2	%	66.3	%	(2.1	)
Third-party travel agents	27.2		23.1		4.1
Call center	8.6		10.6		(2.0	)

Maintenance, materials and repair costs increased by $15.4 million, or 45.4%, in 2012. The increase in maintenance costs is primarily due to $6.8 million in one-time start-up costs of the seat maintenance program, which was introduced and completed in 2012. We do not expect the ongoing expense of our seat maintenance program to have a material impact on our overall future maintenance cost outlook. The average age of our fleet increased to 4.6 years as of December 31, 2012 from 4.5 years as of December 31, 2011. Maintenance expense is expected to increase significantly as our fleet continues to age, resulting in the need for additional repairs over time.

Depreciation and amortization increased by $7.5 million, or 96.6%, primarily due to deferred heavy aircraft maintenance events, which in turn resulted in higher amortization expense recorded in 2012 compared to the prior year period.

Other operating expenses in 2012 increased by $36.7 million, or 40.3%, compared to 2011 primarily due to an increase in departures of 19.9%. Overall increased rates at the airports we serve resulted in increased variable operating costs such as ground handling expenses and travel and lodging expense in 2012 compared to the prior year. The increase on a per-ASM basis of 17.7% is primarily due to a shift in our route network to include higher volumes at the higher-cost airports we serve. In addition, we experienced increases in travel and lodging costs driven by both volume and hotel rate increases associated with increased training and scope of operations, as well as higher passenger re-accommodation expenses associated with slightly higher flight cancellations during 2012. We also incurred additional expenses related to the implementation of an Enterprise Resource Planning (ERP) system.

Special charges (credits) for 2012 primarily include a $9.1 million gain related to the sale of four permanent air carrier slots at Ronald Reagan National Airport (DCA), offset by $0.6 million in secondary offering costs. Special charges (credits) for 2011 relate to termination costs of $2.6 million in connection with our IPO, including $1.8 million paid to Indigo Partners, LLC to terminate its professional services agreement with us and $0.5 million paid to three individual, unaffiliated holders of our subordinated notes.

2011 compared to 2010

Our operating expenses increased by $214.4 million, or 30.1%, for 2011 compared to the corresponding period in 2010. The increase is primarily related to a 56.3% increase in fuel costs, 16.2% increase in labor cost, and a 14.9% increase in aircraft rent.

Aircraft fuel expense for 2011 increased $139.8 million, or 56.3%, compared to the prior year period due to a 35.3% increase in the average price of aircraft fuel per gallon and a 13.5% increase in gallons consumed. Aircraft fuel expense represented 41.9% of our total operating expenses for 2011.

The difference between aircraft fuel expense and economic fuel expense and the elements of the changes are illustrated in the following table:



	Year Ended December 31,						Percent Change
	2011			2010			Percent Change
	(in thousands, except per-gallon amounts)
Into-plane fuel expense	$	392,278		$	251,754		55.8	%
Cash received from settled derivatives, net of cash settlements paid	(7,436		)	(1,483		)	401.4	%
Economic fuel expense	384,842			250,271			53.8	%
Impact on fuel expense from unrealized (gains) and losses arising from mark-to-market adjustments to our outstanding fuel derivatives	3,204			(2,065		)	(255.2	)%
Aircraft fuel expense (per Statement of Operations)	$	388,046		$	248,206		56.3	%
Fuel gallons consumed	121,030			106,628			13.5	%
Economic fuel cost per gallon	$	3.18		$	2.35		35.3	%
Into-plane fuel cost per gallon	$	3.24		$	2.36		37.3	%

Labor costs for 2011 increased by $25.3 million, or 16.2%, compared to 2010, primarily due to increased headcount and increased pilot rates. Our pilot and flight attendant headcount increased 10% and 16%, respectively, as we increased our fleet size by 15.6% via the addition of five aircraft during 2011. The increase in labor costs was also driven by the increase in pilot labor rates by approximately 11% during 2011.

Aircraft rent expense for 2011 increased by $15.1 million, or 14.9%, compared to 2010 mainly due to taking delivery of five Airbus A320 aircraft which were financed via operating leases. In addition, approximately $1.5 million in maintenance reserves were expensed as supplemental rent in 2011 as it was deemed they would not be reimbursed.

Distribution expense for 2011 increased by $10.2 million, or 24.7%, compared to 2010, primarily due to increased credit card fees driven by the 37.1% increase in revenue. Additionally, there was a shift in the percentage of bookings made from our website to more expensive third-party distribution channels (GDSs), which increased to approximately 23.1% in 2011 from approximately 15.1% in 2010. This shift also drove the increase in distribution expense on a per unit basis, along with the increase in credit card fees per unit due to the growth in revenues outpacing the growth in units year over year. The following table shows our distribution channel usage:

	2011		2010		Change
Website	66.3	%	75.2	%	(8.9	)
Third-party travel agents	23.1		15.1		8.0
Call center	10.6		9.7		0.9

Maintenance, materials and repair costs for 2011 increased by $7.0 million, or 25.8%, compared to 2010. This increase was primarily due to a 31.7% increase in flight-hour-based maintenance expenses driven by higher flight hours. Non-flight-hour based maintenance increased 16.3% as a result of the timing of scheduled maintenance events and the aging fleet. As the fleet ages, we expect that maintenance costs and related out of service time to complete the maintenance will increase.

The increase in capacity during 2011 resulted in increased landing fees and other operating expenses in 2011 compared to 2010.

Other operating expenses for 2011 increased by $7.4 million, or 8.9%, compared to 2010 and are generally driven by the increase in capacity, new stations start-ups, and increases in rates. We experienced notable increases in ground handling and crew travel and lodging cost partly due to increased flights and the changes in route mix. These increases in cost were offset by a decrease in costs incurred to accommodate displaced passengers due to the aggressive management of cost and strict adherence to our accommodation policy.

Special charges (credits) for 2011 increased by $2.6 million, or 412.7%, compared to 2010 due to termination costs incurred in connection with the IPO during the second quarter of 2011, comprised of $1.8 million paid to Indigo Partners, LLC

to terminate its professional services agreement with us and $0.5 million paid to three individual, unaffiliated holders of our subordinated notes.

Other (income) expense, net

2012 compared to 2011

Other (income) expense, net decreased by $22.1 million to $0.6 million net income for 2012 from $21.6 million net expense for 2011. Interest expense and corresponding capitalized interest in 2012 and 2011 primarily relates to interest on pre-delivery deposits and interest related to the TRA.

2011 compared to 2010

Other (income) expense, net decreased by $27.1 million to $21.6 million net expense for 2011 from $48.7 million net expense for 2010. The decrease is primarily related to interest on debt for only five months in 2011 compared to a full year in 2010 as a result of the elimination of our debt in conjunction with the IPO in June of 2011. Related-party interest expense incurred during 2011 and 2010 was $21.0 million and $44.6 million, respectively, and consisted primarily of paid-in-kind interest on notes and preferred stock dividends due to related parties. Non-related party interest expense during 2011 and 2010 was $3.8 million and $5.7 million, respectively.

Income Taxes

As of December 31, 2012, the Company has fully utilized an alternative minimum tax (“AMT”) credit carryforward of approximately $3.2 million and federal net operating losses (“NOLs”) of approximately $20.8 million against federal taxable income. In addition, as of December 31, 2012 and 2011, we had state NOLs of approximately $2.2 million and $9.1 million, respectively, which can be used to offset future state taxable income. State net operating losses begin to expire in 2017. The effective tax rate for 2012 was approximately 37.9% compared to 37.8% in the prior year period.

At December 31, 2009, we had recorded a full valuation allowance against existing net deferred tax assets. As of September 30, 2010, we determined that, under generally accepted accounting principles, the valuation allowance should be reduced by $53.5 million, which we recognized as a deferred tax benefit.

Immediately prior to the IPO, we entered into the Tax Receivable Agreement and thereby distributed to the Pre-IPO Stockholders the right to receive a pro rata share of the future payments to be made under such agreement. These future payments to the Pre-IPO Stockholders will be in an amount equal to 90% of the cash savings in federal income tax realized by us by virtue of our future use of federal NOL, deferred interest deductions and certain tax credits held by us as of March 31, 2011. Please see “Certain Relationships and Related Transactions—Tax Receivable Agreement.”
