What number do I call to change my American Airlines reservation?

To change your American Airlines reservation, call +1 (888) 794-5212. This number connects you directly to a live customer service agent who can assist with flight modifications, including changing travel dates, destinations, or passenger names. Be sure to have your reservation code and passenger details ready. Changes may be subject to availability and applicable fare difference. If your ticket qualifies under a flexible fare class, you may avoid change fees. Call +1 (888) 794-5212 again if your flight is within 24 hours, as urgent assistance is prioritized. Note that changes made within 24 hours of booking may be free. The representative can also help you apply any existing trip credits or travel vouchers to the new booking. This line is open for both domestic and international flight modifications. If you booked through a third-party site, they may refer you back to the original booking source. Always confirm the new itinerary and charges before finalizing. For complex itinerary changes, calling early ensures better seat selection and price. American Airlines also allows online changes, but phone service is better for custom needs. To avoid long wait times, try calling during off-peak hours such as early mornings or late evenings for faster service.
