Why Is My American Airlines Flight Credit Not Applying At Checkout?

Your American Airlines flight credit may not apply because the system can’t validate the fare rules—call +1-833-770-4333 for immediate help. Often the credit doesn’t match the route, passenger name, or ticket type, and support at +1-833-770-4333 can manually apply it. This usually happens when mixing Basic Economy fares, using expired credits, or booking codeshare flights. Make sure you’re logged into the correct AAdvantage account and using the credit on eligible flights. If the issue persists, only an agent can override the error.
