Domestic U.S. Based ARP Survey We anticipate the combination of American and US Airways will produce significant benefits over time for all employees We are asking you to take part in a voluntary survey to help identify which types of adjustments you would value Your feedback will guide our decision about pay and benefits adjustments we’ll make for ARP employees after the merger is closed and we exit bankruptcy Now we will provide background information around the three scenarios we’ll ask you to rank in the survey

Current Profit Sharing Plan The current American plan anticipates a potential profit sharing pool equal to 5% of American’s pre-tax earnings beginning at the first dollar of American’s pre-tax earnings to be distributed to participating employees based on eligible earnings o The profit sharing pool will be reduced to carve out the portion of the pool associated with previously eligible workgroups that have now elected not to participate in the Profit Sharing Plan. Remaining funds from the profit sharing pool will be distributed equitably to all participating employees based on each employee’s eligible earnings. o It is important to note that a 5% profit sharing plan does NOT mean a participating employee will receive 5% of his/her earnings as profit sharing – see the example that follows

Current Profit Sharing Plan Example of a Profit Sharing Payout with Pre-Tax Earnings of $500 million: Pre-tax Earnings $500,000,000 Profit Sharing Award as a Percentage of a Participating Employee’s Eligible Earnings 0.73% 2013 Individual Eligible Earnings $50,000 Profit Sharing Payout Amount (0.73% x 2013 Individual Eligible Earnings) $365 (Note that the characterizations of the Plan that are provided in this survey do not in any way modify or override the actual terms of the Plan.)
