Delays experienced in boarding/take off due to incoming plane delayed. However, the boarding time/depart time in the app was significantly delayed in providing these updates. Usually not updated until an hour after we should have already boarded. Poorly managed.

Delays experienced in boarding/take off due to incoming plane delayed. However, the boarding time/depart time in the app was significantly delayed in providing these updates. Usually not updated until an hour after we should have already boarded. Poorly managed.

Plane was delayed for 6 hours, at first by weather, which is understandable, but was further delayed with NO given reason for 2 1/2 hours more. We had no clue when we were going to depart actually until they opened the ramp. VERY POOR to ZERO COMMUNICATION!!!

When I'm on a 5hr 22 minute flight I expect food to be purchased. Especially when American makes a very tight connection time where u have to run to make the long flight. Chips and nuts are unacceptable and being told you should be in first class to get a meal is also unacceptable. I didn't change the flight times American Airlines did.

At least it was a short flight. Greyhound with wings.

Flight attendants on American Airlines are rude very harsh with their time of voice. Nearly identical experience as spirit airlines. However, from Spirit Airlines, you expect this level of mediocre service. You do not expect this from the big three..

The plane had maintenance issues and didn't leave after 72 hours

The staff were very nice! However when our first flight got delayed an hour, the second connection flight was not delayed and the layover was only 40 minutes. When we rushed and made it to our gate for the connection flight, the gate said it had moved to another section of the airport. We barley made it to the connection flight, and overall we were very stressed. We asked about taking a later time for the second connection flight, but the other option was much later and we would have to wait at the airport for 9+ hours. I just wish American Airlines could have moved the second connection flight to a later time too for its customers, and thank you for taking the time to read my review.

Flight was canceled and then rescheduled on another flight. Paid for first class but moved to the back of the plane. Then put up in the worst/dirtiest hotel I’ve ever stayed in. American Airlines should be ashamed of putting their passengers/customers in a place that filthy.

Our flight got changed and/or delayed 8 times before we boarded.

The flight was on time, boarding process good. Good value flight.
