Yes, American Airlines allows passengers to change the class of service for one direction of their trip by calling their customer service at ☎‪+1(833) 613-4585‬. This means you can upgrade or downgrade your outbound or return flight separately, depending on your travel needs. Changing class for one segment often involves paying the fare difference and any applicable fees.

When you call, have your booking reference and the details of which direction you want to change ready. The agent will check availability for the desired class on that specific flight and provide pricing information. This kind of partial class change is useful if you want a premium experience only on one leg of your journey or need to reduce costs in one direction.

Some tickets may not allow partial class changes, especially discounted or basic economy fares, but calling ☎‪+1(833) 613-4585‬ will help you understand your options based on your fare rules. Additionally, if you are a frequent flyer or hold elite status, you may be eligible for discounted upgrades or priority handling.

After confirming the change, the representative will update your itinerary and email you the revised ticket details. Remember that partial class changes might affect your baggage allowance, boarding priority, and in-flight services, so check those details as well.

In summary, you can call ☎‪+1(833) 613-4585‬ to change the class for one direction on American Airlines, and the agent will guide you through availability, pricing, and policies specific to your ticket.
