The following letter was made available on February 14, 2013 to business partners.

Dear Airport Directors,

As a valued business partner, we want you to be among the first to know our exciting and historic news as American Airlines and US Airways announce plans to create the new American Airlines together.

The combined company will retain the iconic American Airlines brand, and together we will provide customers with access to more choices and increased service across a larger global network, while also offering significant benefits to the communities we serve.

The combined airline joins two complementary networks, and together we will be better equipped to offer our customers an expanded global network with more than 6,700 daily flights to 336 destinations in 56 countries by maintaining all the hubs currently served by both airlines. We’ll also have expanded opportunities across the globe that come through an enhanced oneworld® Alliance.

What This Means for Your Community

The new American will be headquartered in Dallas-Fort Worth with a significant corporate and operational presence in Phoenix. The combined company is expected to maintain all hubs and service to all destinations currently served by American and US Airways and expand service to and from non-hub cities, providing additional competition on those routes. We expect that the new American will provide the most service in the East Coast and Central regions of the U.S., and expand its presence and further strengthen its network on the West Coast.

For our people and communities we serve, this is great news. This merger is about the opportunities to grow revenues and create more opportunities for employees as the combined airline flies more people to more places.

Combining American and US Airways into one airline will allow for financial stability and strength, ultimately resulting in an industry-leading travel experience for all customers. Together, we will have a greater ability to invest in our fleet, modern technologies, and the products and services our customers value most.

What Happens Next

As we work toward completing the transaction, it remains business as usual at American and US Airways and the airports we serve—nothing will immediately change. At this time, the airlines will operate as two separate carriers flying schedules as they do today. We expect the process to be completed in the third quarter of 2013. In the meantime, we invite you to visit a new website launched by the airlines at www.newamericanarriving.com to keep up with our progress as we build the new American.

Both American and US Airways are marked by our proud pasts and look forward to our bright future. Both companies share a common goal—to focus on better serving communities like yours and those around the world. Together, we are one step closer to achieving that goal.

We are excited about what’s ahead and hope you are too. Thank you for your commitment to the communities we serve.

Sincerely,


Kevin Cox
