Can I change my flight itinerary online for my American Airlines flight?

Yes, you can change your American Airlines flight itinerary online, provided you booked your flight online through American Airlines or its partner websites. If you booked through a travel agency or a third-party website, you may need to contact the agency or website directly to make changes to your itinerary.

To change your flight itinerary online, simply visit the American Airlines website and navigate to the 'Manage Reservations' section. You will need to provide your last name and booking reference number to access your reservation. From there, you can make changes to your flight dates, times, or even upgrade to a different class of service. Please note that any changes you make to your itinerary may be subject to change fees and fare differences.
