American Airlines has a comprehensive cancellation policy designed to accommodate various passenger needs, offering flexibility across different fare types and circumstances. The airline provides a 24-hour cancellation window for all ticket types, allowing passengers to cancel their flight within 24 hours of booking and receive a full refund, provided the departure is at least two days away. This policy applies to both refundable and non-refundable tickets, ensuring travelers can make changes without financial penalty during this period.

Refundable tickets, such as those in Main Cabin, Premium Economy, Business, or First Class, offer the most flexibility. Travelers can cancel these tickets at any time before departure and receive a full refund to the original payment method. Refunds are typically processed within seven business days for credit card payments.

For non-refundable tickets, American Airlines generally does not offer cash refunds. However, passengers may receive a travel credit for the value of the ticket if they cancel before departure. This credit is valid for one year from the original ticket issue date. Additionally, if a flight is canceled by the airline or significantly changed, passengers are entitled to a refund, even if the ticket was non-refundable.

Basic Economy fares have more restrictions. Typically, these tickets are non-refundable and non-changeable. However, American Airlines allows cancellations for a fee of $99, provided the passenger is an AAdvantage member and the travel is entirely within the United States. The refund in this case is issued as a travel credit.

In certain situations, such as the death of the passenger or a traveling companion, or if the passenger receives military orders, American Airlines may offer a refund on non-refundable tickets. Documentation is required to process such refunds.

Passengers can cancel their flights through the "Manage Trips" section on the American Airlines website or mobile app. It's important to note that cancellation policies may vary for tickets purchased through travel agencies or third-party websites; in such cases, contacting the seller directly is recommended.

Overall, American Airlines’ cancellation policy is designed to offer flexibility and support to passengers. Understanding the specifics of your ticket type and the associated policies can help ensure a smooth process if changes to your travel plans become necessary.
