American Airlines has a change flight policy that allows passengers to make changes to their flights, subject to certain conditions and fees. Here are the key details:

Changes can be made to American Airlines flights up to 24 hours before the scheduled departure time.

If you need to change your flight within 24 hours of the scheduled departure time, you may be eligible for a same-day flight change.

The cost to change your flight depends on several factors, including the fare type, destination, and the number of days before the flight.

If you purchased a non-refundable ticket, you may be charged a change fee in addition to any difference in fare.

If you purchased a refundable ticket, you may be able to make changes without paying a change fee, but you may still be subject to any difference in fare.

If American Airlines cancels your flight or changes it significantly, you may be able to change your flight without paying a fee.

You can make changes to your flight online, through the American Airlines app, or by calling customer service.

It's important to note that policies and fees are subject to change, so it's a good idea to check with American Airlines for the most up-to-date information before making any changes to your flight.
