Creating a Premier Global Carrier March 6, 2013 Issue 3 Merger Takes the Stage in New York Conference The American Airlines-US Airways merger was the talk of the Street on Monday at the annual JP Morgan Aviation, Transportation and Defense Conference, where US CEO Doug Parker was invited as keynote speaker. The conference provides the investment community with an opportunity to gain insight into a select group of companies in the aviation industry and other industries. On stage in front of industry leaders and experts, Doug discussed the numerous benefits of a merger for the millions of people affected by the airline business, from employees to passengers to communities throughout the world. Audio playback of Doug’s presentation, “Creating A Premier Global Carrier,” can be found on usairways. com (Company info >> Investor relations >> Webcasts). “We now have a network that is as strong as Delta and United, so we can pay people the same as Delta and United pay. And that is what this plan calls for. That’s why we got the support of the employees on both sides, because they know that a strong airline is good for employees, and they wanted to support the chance to have a stronger airline.” – Doug Parker Union unity Our merger continues to receive support from US Airways’ and American Airlines’ labor unions. Last Thursday, US Airways flight attendants, represented by the Association for Flight Attendants – CWA, voted by an overwhelming margin to ratify a new contract that provides immediate pay increases and opens negotiations with their future colleagues at American Airlines under a merger scenario. At the JP Morgan conference on Monday, Keith Wilson, president of the Allied Pilots Association, said, “We are pleased to be here in support of the new American Airlines and its new management team. The combination of American and US Airways is transformational for the entire industry and beneficial for our respective employees. We are gratified that investors recognize the tremendous value that will be created by putting these two great airlines together.” From left to right, Industry Analysis Chairman, Allied Pilots Association, Dennis Tajer; President, Allied Pilots Association, Keith Wilson; US CEO Doug Parker; President, US Airline Pilots Association, Gary Hummel; US CFO Derek Kerr and Business Intelligence Comittee Chairman, US Airline Pilots Association, John Owens.
