Yes, you can change someone's name on a flight ticket with American Airlines under specific guidelines. Minor corrections, such as fixing spelling errors of up to three characters, are typically allowed without a fee. For major changes, like legal name updates due to marriage, divorce, or other reasons, you’ll need to provide official documents, such as a marriage certificate or court order. It’s essential to initiate the name change at least 48 hours before the flight. Fees may apply depending on the nature of the change. For assistance, contact American Airlines Customer Service to ensure a smooth and accurate process.
