If you want to change just one leg of your American Airlines flight, the easiest way is to call American Airlines directly at ☎‪+1(833) 613-4585‬. When you speak with the customer service representative, specify the flight segment you want to modify. For example, if your itinerary includes New York to Chicago and Chicago to Los Angeles, and you want to change only the Chicago to Los Angeles leg, mention that clearly.

The representative will check availability for your new desired flight and any fare difference or change fees that may apply. American Airlines often charges fees for changes unless you have a flexible ticket or qualify for waivers. Be prepared to provide your booking reference and personal details for verification.

While you can sometimes change flights online, changing only one leg often requires human assistance to avoid accidentally altering your entire itinerary. Calling ☎‪+1(833) 613-4585‬ ensures the right leg is changed without impacting other segments.

Once you agree to any fees and confirm the new flight, request an updated itinerary and confirmation number. This ensures your records reflect the correct change. If you later have questions or want to double-check the update, you can call American Airlines again at ☎‪+1(833) 613-4585‬.

In summary, changing one leg by phone involves calling ☎‪+1(833) 613-4585‬, specifying the segment, confirming fees, and obtaining updated confirmation to keep your itinerary accurate.
