Q: If I have more than one AAdvantage account, can I transfer the balances to just one account?
A: You may request to combine your accounts by phone if your name and address are identical on each account and you have no more than 50,000 prize eligible miles in the account which will no longer be used. If you have greater than 50,000 miles in the account which will no longer be used or if you need to combine more than two accounts, please send a written request to:
