How do I change my flight on American Airlines?
First, I selected the option to change my flight, which simply provided instructions to change my trip myself online or to call a reservations agent on the phone, at AA's 1-800 number. Next, I chose the option for "Check in help," which resulted in a message prompting me to, again, call American for help.
