June 10, 2013 > Issue 17 Special Edition Arrivals A joint merger communication for employees of the new American New Leadership Arriving Creating a premier global carrier Today we announced the senior leadership team that will lead the new American Airlines once we are ready to take off as one company. Not only does today’s announcement signify a key milestone in making our vision of becoming the world’s greatest airline a reality, but it also means that our company will benefit from the unparalleled industry experience of senior leaders from both American and US Airways. As you know, Tom Horton and Doug Parker will serve as Chairman of the Board and CEO, respectively, of the new American. The leaders we announced today will come together to form the most experienced and most talented team in the aviation industry. While these individuals have unique backgrounds and come from two different companies, they share a love for aviation and a commitment to our team members, customer service and safety. “We will engage, motivate and respect the more than 100,000 hard-working team members of the new American. Our job is to support all of you – give you the tools and information you need to do your jobs and then let you do it as the exceptional and experienced group of aviation professionals you are. This team was built to do just that.”—Doug Parker “As we bring the restructuring to a close, the new American is strong, renewed and positioned for a successful merger. American’s leaders will continue to work very closely with their counterparts throughout the merger planning to build upon the momentum everyone has worked so hard to create.”—Tom Horton As we reach this milestone, we do so with incredible momentum. We continue to make progress on the planning efforts that are key to a successful integration following the close of the merger, which we continue to expect to occur in the third quarter of 2013. We will be one team soon! Leading the New American CEO Doug Parker will lead the new senior leadership team and company, and has selected the following individuals to join the new leadership team: • Scott Kirby — President • Elise Eberwein — EVP, People and Communications • Bev Goulet — Chief Integration Officer • Robert Isom — Chief Operating Officer and CEO of US Airways, Inc. post-close • Stephen Johnson — EVP, Corporate Affairs • Derek Kerr — Chief Financial Officer • Maya Leibman — Chief Information Officer • Will Ris — SVP, Government Affairs Mergers unfortunately result in departures, and there are some on both teams. “I want to take this opportunity to specifically thank some of the outstanding senior executives at American,” said Doug. “The American restructuring is far and away the most successful in aviation history and it would not be possible without the exceptional and dedicated work of people like Dan Garton, Bella Goren, Gary Kennedy, Denise Lynn, Jim Ream, Jon Snook and Virasb Vahidi. We are grateful for their phenomenal work and dedication and are committed to building on the foundation they have put in place.” Check out www.newAmericanarriving.com for key materials related to the announcement, including the press release, expanded bios of the executive team and letters from Tom and Doug. 1 corp.comm@aa.com Send us your questions! corporate.communications@usairways.com

Organizing for Success Collaboration has been a hallmark of the American and US Airways leadership teams and it will continue to be key to the success of the new American. The new airline will be structured to ensure that team members making decisions about our network are working daily with team members responsible for operating the airline. Dan Garton will step down as President and Chief Executive Officer of American Eagle Airlines later this year. A successor will be named prior to Dans departure. Building our New Team A Note from the People Dept. Dear Team Members of the New American Airlines, With our new senior leadership team named, integration planning of our airlines and team members is now front and center. Understandably, the question everyone has is: Whats going to happen to me It may not be that direct, but the questions ultimately come back to how this merger will impact us as individuals, what opportunities we may have and when we can feel certain about our individual futures. Our joint Human Resources integration team is working hard to enable a smooth transition as we approach legal close, as well as planning the next steps to full airline integration. We are taking the time to understand the respective airlines people policies, processes and programs to ensure that we select the right approach to talent, rewards and HR operations for the new American Airlines. Because we have two separate airlines and employee groups to continue to support during the transition, we have hired some of the best talent in the business Aon Hewitt to work with our teams to help set us up for success. While were hesitant to rely on too many consultants, we also know we need outside expertise to help us with the complex integration work that lies ahead. While many things will remain the same in the near future, we are committed to keeping you updated on the critical people decisions as they are made and implemented after the merger closes. We are working with the integration teams to gain a deeper understanding of how the two organizations are currently structured. We are working with Bev Goulet and the Integration Management Office to continue this gap analysis and lay the new structure out in a way that doesnt cause disruption and allows both airlines to continue to operate reliably with our customers and team members in mind every step of the way. Our new senior leaders are reviewing their organizations to decide what team structure makes the most sense for the new airline. They are also meeting with the next level of officers at both airlines to understand each individuals capabilities and experiences and to discuss their potential roles and interests. We know that the selection of the new American officer team is among the most critical decisions we will make as a combined airline, and we are committed to making informed leadership selections that ensure the best opportunity for a successful and growing business for everyone. As Doug relayed today, we intend to have these officers selected by the day the merger transaction closes. Given the scope and scale of the organization and talent of managers at both airlines, our joint HR integration team is developing a talent selection/staffing process for the next levels of our organization, and we know this is the information everyone wants next. Our goal is to continue to make objective and informed talent decisions, and please know we will provide guidance soon on this next step. For now, we need everyone to continue to run two great airlines and work collaboratively as we begin to integrate later this year. Thanks for continuing to take care of our customers, and for continuing to support the frontline team members at both airlines as summer travel heats up. —Elise 2 corp.comm@aa.com Send us your questions! corporate.communications@usairways.com
