In 1989, American implemented an expiration policy where miles would expire if there wasn’t any account activity over a three-year period. In 2012, American revised their policy by lowering the required activity timeframe to 18 months. Miles that were not previously subject to expiration were given a 25% bonus before adopting the new 18-month expiration policy. In March 2022, American again revised their expiration policy by increasing the timeframe for required activity to 24 months. Miles in members' accounts who are under 21 years of age are exempt from the account activity requirement. Expired miles cannot be used for award travel. To reactivate previously earned miles, AAdvantage plan members can pay a fee ranging from $200–$600. Of the three main legacy carriers in the United States, American is the only one that continues to maintain an expiration policy; Delta and United both relinquished such policies in recent years.
