American Airlines’ cancellation policy allows passengers to cancel their flights within 24 hours of booking without any fees if the flight was booked at least two days before departure. For non-refundable tickets, a cancellation fee may apply depending on the fare type, and the remaining balance is issued as a travel credit. Refundable tickets can be canceled anytime, with a full refund issued. Basic Economy fares are typically non-refundable and non-changeable. In case of flight disruptions or cancellations by the airline, passengers are eligible for rebooking on a new flight or a refund. Policies may vary based on the route and fare class.
