Yes, American Airlines allows you to change your passenger name, but with certain restrictions. Minor corrections, such as fixing spelling mistakes of up to three characters, are typically allowed without a fee. For major name changes, like those due to marriage or legal reasons, you will need to provide supporting documents (e.g., a marriage certificate or court order). There may be fees associated with more significant changes. It's important to request any name changes at least 48 hours before your flight. To initiate the process, contact American Airlines Customer Service for further guidance and to confirm the requirements.
