A joint merger communication for employees of the new American

Creating a premier global carrier

Town Hall Talk

On the heels of last week’s senior leadership announcement, the new team gathered in Dallas-Ft. Worth to meet with 2,000 American Airlines employees at the company’s headquarters and at the airport. The new executives – Doug Parker, Scott Kirby, Elise Eberwein, Bev Goulet, Robert Isom, Steve Johnson, Derek Kerr and Will Ris – discussed the integration process and answered questions from employees at three different Q&A sessions. Maya

Leibman was also on hand in Phoenix to address questions from her colleagues in the IT department.

Above all, employees were curious about when other leadership announcements will be made, how the new team will influence the culture of the combined company through communication, and of course, what the combined company’s non-rev travel program will look like. We’ll have details on all this and more in the coming weeks, so keep an eye out for additional news!

Uniform Survey Results Are In!

Many of you recently participated in a survey to share your opinions about new uniforms for Pilots, Flight Attendants, Airport Agents, Premium Service Team

Members and Club representatives. We’re thrilled that so many of you – almost

24,000! – shared your thoughts with us.

We heard many diverse opinions, but identified several common themes across all workgroups and companies. However, there were other elements – such as color – where there was not an overall preference. We understand that your new uniforms are important, so we’ll continue to review our options with KAUFMANFRANCO before making decisions for those components. The graphic to the right highlights a few of the common themes.

We shared this feedback with KAUFMANFRANCO, and we’re confident they’ll use their expertise to create uniforms that look great, feel great and showcase the new American. We’ll unveil the initial sketches in the coming months, so stay tuned to new Jetnet and Wings for the latest uniform news.

Capitol-izing on Our Strengths

Doug Parker and American’s SVP and General Counsel Gary Kennedy paid another visit to the Senate this morning to expand on the benefits of our proposed deal. The hearing, before the Senate Subcommittee on Aviation Operations, Safety and Security, focused on the merger of American and US Airways. Doug and Gary were joined by more than 25 union representatives from both carriers. Here are a few choice words from their written testimonies.

“We will remain committed to extensive service to small- and medium-sized communities throughout our merged network and, where appropriate, we expect to increase such service and add destinations. The new American Airlines will therefore give passengers in small- and medium-sized communities better connecting options, and service to more places than ever before at more convenient times.”– Doug Parker

“The enthusiasm among our work groups for this merger will be a powerful driving force behind the new American for years to come. Our customers also stand to benefit greatly. The new American expects to win more business from passengers here at home and across the globe, and winning that business will allow the company to invest in its people and its products, all with the goal of restoring American’s position as one of the world’s great airlines.”– Gary Kennedy

An Update from the Integration Team

June 2013

Fellow Employees:

In keeping with our commitment to keep you informed, here is an update on work being done to integrate our two airlines. As you know, the 29 Integration Planning Teams are developing plans for how to integrate following closing our commercial, customer-facing, operations and corporate and staff functions, and several cross-functional taskforces are working on specific objectives.

All of the teams are making strong, steady progress, and we are on track to close the merger in late August or early September. We expect it will take approximately two years to fully integrate our two companies, and for most people, very little will change on Day One of the merger closing.

Right now, teams are laser-focused on ensuring a seamless customer and people experience on Day One. Top priorities include:

> Cross Planning Team Customer Integration – We know many of you are concerned that the merger will create some confusion for our customers. To alleviate that concern, teams are focused on working across organizations to ensure that all change events are bundled in the most logical way: changes must be user friendly, easy to communicate, and paced not to overburden our customers and employees. The team will be working with all 29 Integration Planning Teams to inform and train employees to handle anything that comes their way – ensuring that we deliver on our promises to customers.

> Airport Co-Location – The Facilities, Airport Operations and International Airport Operations Planning Teams are hard at work identifying all of the airports where American and US Airways have a presence, examining resources, and creating plans to move station operations together in a way that makes sense for customers and employees. This is a huge undertaking, but we should have a solid plan in place shortly to identify which stations will be able to operate side-by-side soon after close, and which stations will follow suit in a staged and careful manner with the least disruption.

> Crisis Response – As the saying goes, “By failing to prepare, you are preparing to fail.” The Crisis Response Planning Team is hard at work aligning the crisis response plans at each airline with the intent to conduct a joint drill before merger closing with employees at both American and US Airways.

> Codeshare – Much work is going on to allow American and US Airways customers to combine flights on a single itinerary. All eyes are on implementing codeshare capabilities as soon as possible after merger closing. This is an important part of the merger and we have all hands on deck working to deliver – not only for customers, but to provide training for customer-facing employees so they can easily explain the options available.

> Single Operating Certificate (SOC) – Work has already begun for American and US Airways to achieve a SOC from the FAA, which basically means the government officially views the two merger partners as one entity. The Single Operating Certificate Planning team has already outlined the implementation process, highlighting the development, approval and execution of a Transition Plan. The Team is working to achieve SOC in less than two years after legal close.

> “People Day One” – You will hear a lot about “merger close” or “Merger Day One,” but for many it will also be a “People Day One” experience. Some of our union employees will earn different pay and benefits as soon as the merger closes. The HR Planning Team is focused on meeting those contractual obligations by ensuring our HR systems are ready to handle those changes. It’s important to note that for many, if not most employees, nothing will change on Day One – we will continue to run two separate operations. We will communicate extensively as we get closer to legal close those things that are changing, and those that are staying the same. Stay tuned . . .

Please watch for regular updates from us as the work of the IMO continues. We encourage you to read each weekly edition of our joint merger newsletter Arrivals, which you can find on Jetnet or Wings, to learn more about what’s happening across both airlines.

While our integration planning teams continue their work, the biggest priority for all of our employees is running both airlines safely while maintaining a tremendous focus on our customers. Our continuing thanks for your hard work and commitment.

Sincerely,

Robert Isom Bev Goulet
