• What is AAirpass?
AAirpass is a prepaid, fixed-rate travel account program, valid for one or more years, typically for individual or corporate flyers who book high fare tickets. AA has also offered lifetime AAirpass accounts in the past, although they are not currently available. AAirpass does not confer elite status directly, but does come with certain benefits, such as preferred check-in and boarding and complimentary Admirals Club membership.
