American Airlines has policies in place to assist travelers who need to cancel their flights. If you cancel within 24 hours of booking, you’re in luck: American Airlines offers a full refund, no questions asked. Beyond the 24-hour window, cancellation fees may apply depending on the type of ticket you hold. Non-refundable tickets can often still be canceled, but the airline typically offers a flight credit for future use instead of a refund. Refundable tickets, on the other hand, can be canceled at any time without fees. To avoid complications, be sure to understand your ticket category and the policies that apply to it.
