Flight was delayed…once landed at ORD, no gates were available so made us wait for 56 minutes after we landed to let us out of the aircraft!

Flight was late and boarding was confusing because gate changed and I didn’t get a notification

On Wednesday, July 30 we were in mid flight from Manchester to Charlotte and we turned around because the right engine was malfunctioning. That was the last flight out of Manchester that night. I was rebooked for Thursday, which became a weather event Friday. There were no seats left on the flight from Manchester to Charlotte. Consequently I didn’t leave Manchester until Saturday morning and we flew to Chicago so to say the least my scheduled flight and return to Iowa was three days off and it messed with my business schedule. Consequently cash flow. I would like some sort of acknowledgment of this event.

We had to turn around and head back to Manchester. Problem with a plane engine.

Was a normal flight but it was delayed, and there wasn't an explanation.

My initial flight to ORD was extended without reason. We circled the airport a few time and then drove on the ground for at least 20 minutes. These kinds of delays are annoying but somewhat expected… it would be nice if the crew would make an announcement to give updates on how long we could expect to be delayed.

Boarding was disorganized and delayed because they overbooked and wanted people to give up seats then further delayed due to an issue with the plane. They did not load my bag and it took a day for them to return it. Flight attendant was lovely and the only positive thing about this trip.

a321 business class not up to transcontinental & international flight standards

Seats are weirdly bent, I felt hunched the entire time.

I rarely vote ‘Excellent’ but this AA flight out of LGA was amazing. On time departure, early arrival, amazing crew, smooth flight, baggage came out quickly. It was the best airport/ flight experience that anyone could ask for/dream of. Highly recommend. I usually fly Delta but American Airlines really stepped up their game.
