After the 24-hour window, cancellation fees may apply depending on the fare class. For non-refundable tickets, you will receive a credit for future travel, minus the cancellation fee, if applicable. American Airlines has also introduced more flexible policies in recent years, especially for Main Cabin and higher classes, allowing for easier cancellations and changes without hefty penalties. Refundable tickets offer the most flexibility, as they can be canceled at any time for a full refund.
