miles expiration

Miles expiration refers to the deadline by which frequent flyer miles must be used before they become invalid. Airlines typically set a time limit—such as 12 or 24 months—after the last qualifying activity like earning or redeeming miles. If you don’t use or update your miles within this period, they expire and can no longer be redeemed for flights or rewards. To prevent expiration, travelers often need to maintain account activity, such as earning or redeeming miles, within the designated timeframe. Always check your airline’s specific policies, as expiration rules vary.
