AA delayed the flight for 3 hours and 50 minutes, but delayed the last 2 hours, 30 minutes at a time, so if we knew before, could have stayed at home and worked instead of being at the airport wasting time... The plane's crew was excellent, not their fault.

AA delayed the flight for 3 hours and 50 minutes, but delayed the last 2 hours, 30 minutes at a time, so if we knew before, could have stayed at home and worked instead of being at the airport wasting time... The plane's crew was excellent, not their fault.

After arriving in Dallas, the aircraft taxied for an unusually long time and was unable to park at the gate, which caused a significant delay and made me miss my connecting flight. I then had to wait in a very long line to be rebooked, and I was told that no hotel or meal accommodations would be provided. What is even more unacceptable is that my luggage was mishandled and has still not been located. My suitcase contains important medications that I urgently need, and I have been unable to access them due to the airline’s mishandling. This situation has caused me considerable stress and inconvenience, and I need this issue to be resolved immediately.

RIC Staff was not enough. Elderly passengers had to wait 30 minutes to deplane, so we could board and still had to walk as no chairs were provided. And, passenger in front of my seat assignment rammed seat against my legs entire flight time. Was mildly bruised and left thigh still sore.

Liked that it was on time. Staff professional and friendly.

Things were delayed a little. But that didn’t affect my plans. It was fine. I was surprised it was so full thanksgiving day. The crew were friendly and professional.

I appreciated that it was on time, safe and professional. I didn’t like that I wasn’t in a place where I had a window at my window seat. It would have been nice to know that in advance. If it was mentioned in the ticketing, I didn’t notice it.

My flight was delayed about three hours. I got home at 3:30 in the morning very bad experience.

I like that the crew kept us informed but we moved back and forth from gate to gate before the aircraft arrived.

The flight was delayed multiple times, again no fault of American but again the extra cost, for everything makes it feel like a cheap airline! Especially when flights are outrageously expensive already

Horrible. Both legs of my flight were delayed more than 6 hours. No compensation, no screens on the plane, and the plane was not clean.
