Over the summer I wrote a guide to the mind-numbingly complicated differences between an American Airlines trip credit, travel voucher, flight credit and gift card, including a helpful internal grid that the carrier’s employees use:
American has been replacing paper vouchers with ‘trip credits’ which allow payment towards an adult passenger fare on American and American Airlines codeshares only. These can be used as partial payment towards a ticket (topped off with a credit card) or partially used towards full payment of a ticket, with residual amounts emailed to the passenger. Trip credits can also be used to book yourself an extra seat.
Eventually they will become combinable with other forms of payments (eVouchers, gift cards, flight discounts and towards award ticket taxes and fees), for multiple passengers in the same booking and for multiple passenger types.
American Airlines has now converted many old ‘flight credits’ into ‘trip credits’. Update: it’s been pointed out to me I should underscore that this process isn’t complete and won’t be for awhile.
These credits have been rolled out not quite ready for prime time. They don’t have full functionality. They can’t even be used for international tickets yet, which seems sort of insane. Eventually they should work as intended, however.
