If you need to speak to a human being at American Airlines, your best bet is to call customer service. American Airlines does not have a live chat feature, so you will need to speak with a customer service representative.
You can reach customer service by calling 1-800-237-4141 from anywhere in the United States, or by using the American Airlines website. American Airlines also offers a phone app for customers who want to make calls from their mobile device.
If you need to speak to a supervisor or a manager, you will need to go to the American Airlines ticket counter and request to speak to a supervisor. You will need to provide your name, the issue you are experiencing, and your contact information.
The supervisor will be able to help you resolve the issue.
