American Airlines offers a flexible cancellation policy to accommodate travelers’ changing plans. If you cancel a flight within 24 hours of booking, you are eligible for a full refund, regardless of the fare type, as long as the booking was made at least two days before departure. Beyond the 24-hour window, the policy varies depending on the fare type. Basic Economy tickets are generally non-refundable, while Main Cabin, Premium Economy, Business, and First-Class fares allow changes and cancellations, though fees may apply depending on the fare conditions. If you purchased a refundable ticket, you can cancel and receive a full refund at any time before departure. American Airlines also offers travel credit for some non-refundable tickets if you need to cancel but still plan to fly in the future.
