Adding a child to your American Airlines reservation is simple when you follow the steps below. Whether you're flying with an infant or a child under 12, you can make the necessary changes easily by phone. For fast assistance, call 1-833-341-5261.


Speak to a live agent who can help you add an infant (under 2 years) or a child to your existing booking.

Prepare your reservation confirmation number, travel dates, and your child's full name and birthdate.

Let the agent know if your child will be traveling as:
A lap infant (under 2, no seat required),
A child with a reserved seat, or
An unaccompanied minor (depending on age and travel rules).

Adding a child may involve:
Taxes or fees for lap infants (usually a percentage of the adult fare),
A full child fare for seat assignments,
Unaccompanied minor service charges (if applicable).

After changes are made, ask the agent to send you an updated itinerary.

For domestic flights, you may need to show proof of age (e.g., birth certificate); international flights may require a passport.
