A DOB correction becomes more urgent when your departure is approaching.

American Airlines allows travelers to access their reservations online using information such as their last name and date of birth, along with a confirmation code or ticket number.

What Information Should You Have Ready?

Before requesting a correction, gather your six-character confirmation code, ticket number, passenger name, correct date of birth, and the government-issued identification you intend to use for travel. Providing accurate information can help the airline or booking agency determine what needs to be corrected. If you purchased your ticket through a travel agency, the agency may need to make the appropriate reservation data correction.

What If the DOB Is Wrong on Your AAdvantage Account?

A reservation and an AAdvantage account can contain passenger information that needs to remain consistent. American Airlines advises AAdvantage members to keep their account information up to date, and its guidance notes that incorrect information can affect the check-in process. If your account information is incorrect, as well as your reservation, ask American Airlines what needs to be updated and in which system. For assistance, you may contact 1-877-898-7186, 1-888-510-9636, and 1-866-381-5038.

What Documents May Be Needed?

For a DOB correction, be prepared to provide information from the government-issued identification or passport that you will use for the journey. The information should accurately reflect your legal identity and travel documents. American Airlines emphasizes that passenger information used for Secure Flight and passport data should be accurate. Therefore, do not provide an approximate birth date simply to make a reservation work.
