When you purchase a ticket on American Airlines, it is a binding contract between you and the airline. This means that even if you change your mind about traveling, you will need to pay your fare and any additional fees associated with your ticket. In some cases, you may be able to cancel your flight without penalty, but this will vary depending on the circumstances. If you have already boarded the plane, there may not be much you can do.
In general, American Airlines will only allow you to cancel your flight within 48 hours of the scheduled departure time, and you will likely need to pay for all of your travel expenses. If you have not boarded the plane, you may be able to cancel your flight without penalty and receive a full refund. It is important to understand the terms and conditions of your ticket before making any decisions. If you have any questions, please contact American Airlines customer service.
