Changing the name on an American Airlines ticket is generally not allowed, as the airline's policy states that tickets are non-transferable. However, there are some exceptions. If there's a minor spelling error or if the name change is due to legal reasons like marriage or divorce, American Airlines may allow modifications. In such cases, you’ll need to provide documentation to support the change. For more significant name changes, such as transferring the ticket to another person, you typically need to cancel the existing booking and rebook under the new name, often incurring additional fees. Always check with customer service for specific details.
