For an American Airlines ticket, name changes are limited. American usually allows minor corrections, like fixing a typo or updating a legal name after marriage, as long as it’s the same traveler. You can check this in “Manage Trips” on their website or app. Full name changes to transfer the ticket to another person aren’t allowed. If the system won’t let you edit the name online, contacting American Airlines customer service is the best option. It’s a good idea to fix any name issues as soon as you notice them to avoid trouble at the airport.
