To cancel your American Airlines flight for free, you need to act within their 24-hour cancellation window. This rule allows you to cancel any ticket, whether refundable or non-refundable, within 24 hours of booking without any fees, as long as the flight was purchased at least two days in advance. After this window closes, the cancellation fees will depend on your fare type. Refundable tickets remain eligible for free cancellations, while non-refundable tickets may incur fees or offer travel credits instead.
To cancel, simply log in to your American Airlines account, locate your booking, and select the cancel option. If you're still within the free cancellation window, you’ll receive a full refund. If not, any applicable fees will be deducted, and you may receive a travel voucher instead of a refund.
