Air Tran
Credits are valid for 12 months after the date on which they were posted to the members’ account.
Alaska
If no mileage is credited to an account during the first nine months after it’s opened, or if an account is inactive for longer than three years, the Alaska Airlines Mileage Plan reserves the right to delete an account and reassign the number.
American

Mileage in a member’s account will not expire so long as the member generates accrual or redemption activity in the account. Unredeemed mileage accumulated in a member’s account will expire at the end of the second calendar year after the last accrual or redemption activity date. For example, mileage earned during the year 2006 is valid until December 31, 2008 unless the member has accrual or redemption activity in the interim.
