American Airlines generally does not allow you to change the name on a ticket once it has been issued. However, they may allow you to make minor corrections to the name (such as fixing a typo or adjusting the spelling), but these changes are typically limited to a small number of characters. For example, if there’s a mistake in the first or last name, you may be able to contact customer service to get it fixed. If you need to change the passenger's name entirely—such as transferring the ticket to another person—American Airlines typically does not permit that. In most cases, the only option would be to cancel the ticket (if it's refundable) and book a new one in the correct name.
