Filed by AMR Corporation

Commission File No. 1-8400

Pursuant to Rule 425 Under the Securities Act of 1933

And Deemed Filed Pursuant to Rule 14a-6

Under the Securities Exchange Act of 1934

Subject Company: US Airways Group, Inc.

Commission File No. 001-8444

The following are posts that will be made on AMR Corporation’s intranet site on June 19, 2013.

 

  1. American Airlines CARE team or Trauma Response team is made up solely of management personnel. What is US Airways’ trauma response team as far as employee involvement, and which type will the new company adopt?

US Airways has a similar approach to its trauma response, including a “Care Team,” comprised of employees from various departments throughout US Airways, such as Airport Customer Service employees, Flight Attendants, Fleet Service employees and all non-contract employees. The team was established in September 2009 and currently has more than 1,300 active members. Like American’s CARE team, its aim is to facilitate the immediate needs of those affected by an aircraft incident, communicate information, and represent the airline.

The specific structure and details of the new American’s trauma response team, and the involvement of our people, is still being determined as part of the integration process. We expect to be able to communicate additional details by merger closing.

 

  2. Is there anywhere I can purchase items like stickers, hats and patches with the new logo?

You can purchase items featuring the new logo in-person or online from the C.R. Smith Museum Gift Shop, and on aabranded.com after a simple registration process. You can also receive a free Launch Day poster featuring our new livery through the American Airlines Material Ordering System (AAMOS), which also requires a brief registration process. Once you are logged in, you can order the poster by searching the AAMOS database for Item No. 22490.

 

  3. How will seniority be integrated for the Agent, Rep and Planner group?

Under the McCaskill-Bond Amendment, American is obligated to ensure that the seniority integration process is “fair and equitable.” Once the merger and the Plan of Reorganization have been approved, we expect that a seniority integration committee made up of elected Agents and Representatives will begin meeting with a committee for US Airways passenger service agents.

 

  4. Will the new American re-staff fleet service clerks to some stations?

American’s staffing will continue to be driven by the staffing formula included in the current AA/TWU collective bargaining agreement until the integration is complete and the US Airways and American Fleet Service Clerks are integrated and under one collective bargaining agreement.

 

  5. When we merge with US Airways, will the base pay of their fleet service clerks increase to match American fleet service clerks’ pay?

Pay for American and US Airways Fleet Service Clerks will continue to be driven by their individual collective bargaining agreements until the integration is complete and the US Airways and American Fleet Service Clerks are integrated and under one collective bargaining agreement.
