AAdvantage members must have mileage earning or redeeming activity once every 18 months in order to retain their miles. Miles will first expire under this 18-month policy on December 15, 2007. If your account has no qualifying activity in any 18-month period, all miles in the account will expire except for those miles earned prior to July 1, 1989 in accounts established prior to January 1, 1989 whose mileage credit will not expire. Each qualifying activity extends the expiration date of all unexpired mileage credit in your account for 18 months from the date of the qualifying activity. Qualifying activity is defined as redeeming any AAdvantage award or accruing mileage credit on any eligible American, American Eagle®, AmericanConnection® or AAdvantage airline participant as well as accruing mileage credit with participating hotels, car rental companies, credit cards, telecommunication providers, and other service providers offering AAdvantage mileage credit.
