As of 2026, American Airlines offers free cancellations and changes for most ticket types, but with specific conditions depending on the "Fare Class." For Main Cabin, Premium Economy, Business, and First Class tickets on domestic and most international routes, there are no change fees; if you cancel, you will receive a Flight Credit for the full value to use within one year. However, Basic Economy tickets are typically non-refundable and non-changeable after the initial 24-hour booking window, though American has recently tested allowing Basic Economy passengers to cancel for a small fee (around $99) to receive a partial credit. Regardless of the fare type, the "24-Hour Refund" rule still applies: if you book at least two days before departure, you can cancel any ticket for a full refund to your original payment method within 24 hours of purchase. For maximum flexibility, "Refundable" fares are still available for a higher price, allowing a cash refund at any time.
