How do I change my seat assignment on my American Airlines flight due to a medical condition?

If you have a medical condition that requires special seating accommodations on your American Airlines flight, you can request a seat change by following these steps:

• Visit the American Airlines website or mobile app and log in to your account
• Go to your reservation and click on the 'Seats' option
• Choose the new seat that meets your medical needs and click on it to select it
• Review your new seat selection and click on 'Confirm' to complete the process

If you are unable to change your seat assignment online, you can also contact American Airlines customer service by phone to request a seat change. Be sure to let them know about your medical condition so they can assist you accordingly. Additionally, it is always a good idea to bring any necessary medical documentation with you when you travel.
