Adding a child to an American Airlines reservation depends on the child’s age and the time of booking. The kids aged 2 years and older need their own ticket and seat. However, infants under 2 years may travel as lap children on eligible flights. Further, if traveling with children on separate reservations, American Airlines can also link the bookings upon request.
