You might be phoning at a busy time or due to a cancelled or delayed flight, which brings us to our second possible explanation.

You can then choose between waiting or attempting to connect with the airline later. Additionally, there are other ways to reach American Airlines Customer Service than dialing. And if you are a member of the Elite group, make sure to contact the lines that have been set aside just for you.
