When you need to adjust your trip by a few days or weeks, American Airlines makes the process seamless on standard fares. While change fees are $0, understanding fare differences is vital.

If your new flight is priced higher than your existing ticket, you pay the difference at the time of modification. If the new flight is cheaper, American Airlines automatically issues a Trip Credit for the leftover funds.
