Changing your name on an American Airlines ticket depends on the reason for the change. Minor name corrections, like fixing a typo, can typically be made by contacting customer service. However, major name changes (e.g., due to marriage or legal reasons) are generally not allowed. If you need a significant change, you may be advised to cancel your current booking and rebook with the correct name, potentially incurring cancellation fees or fare differences. It's important to contact American Airlines directly to explain your situation, as they may offer flexibility in specific circumstances, such as legal name changes.
