Like the fact that the boarding was expedited. But the delay and chaos around the onboarding was not appreciated.

Like the fact that the boarding was expedited. But the delay and chaos around the onboarding was not appreciated.

The flight crew were very helpful. The seats were very close together. There was barely room to sit without touching the person next to you.

I’m an EP on AA every year for more than a decade but this was a very pleasant and surprising experience. Clean and sizable plane for HOU to CHI. 5 row first class. And excellent food in first class the steak option was really good. Your flight attendants even better. Seat 5A

Gluten free snack options and meals that offer both gluten free and dairy free.

Not a bad flight but a long delay boarding and taking off due to the pilot not arriving on time.

I would have preferred a flight voucher and to hop on a different flight. Delayed over 6 hours.

I almost missed my connection in Chicago due to having to wait on a gate to be open I am assuming. Having to run from E terminal to C terminal and I barely made it there before they closed the door. This may not be the actual airline's fault it's crazy how there is so little time between flight especially when they are placed so far apart in the airport.

The Wi-Fi did not work, so you weren't able to watch entertainment on your own device. They did not have wired headphones so you couldn't watch it on the in-seat entertainment screen either. There was plenty of time to do a drink and snag service but the flight attendants chose not to.

The flight was significantly delayed. The inbound flight from EWR was delayed departing because of mechanical problems. My original departure from CLT was 5:28 pm but due to the delay of the inbound flight, after arrival, deplaning, cleaning, boarding, we did not push back from the gate until 9:00 pm. Once in the air, the flight was smooth and what was originally supposed to be an arrival in ORD at 7:30 pm local time turned out to be 9:35 pm.

After the morning frenzy of 35 min wait through CLT security at 4;30 AM, it was nice to have a smooth pleasant boarding experience. This 6:30 AM flight was not full. We were able to get seated swiftly and took off promptly. Nice touch they distributed the old fashioned headsets with 8 mm jacks. Snacks were decent and arrival was uneventful.

Delays and cancellations. Mechanics weren’t on site. Replacement plane took hours to arrive although it should have arrived within 90 minutes. Flight back was cancelled. Ended up driving over 12 hours and wasting 3 days between everything.

Had to wait for a gate for a long time, then waited on the run way for a long time before leaving. The actual flights part was good.

Awful. They won’t help me with anything. I booked on American but they abdicated to Iberia. The ticket was overpriced. Everything negative

I had a positive experience on American. I'm blind and traveling with a guide dog and the flight attendants were so kind, friendly, and helpful towards us. They checked in on us during the flight and they made us feel comfortable and welcomed. There was an hour delay before depature, but overall the flight was a smooth ride. I appreciate that there were no issues on this long flight back home.

Flight was delayed. Staff at the gate effectively and proactively communicated about the delay.

It was late, then the bathroom was inoperable plus it was very hot as well. Plane was very old

the food choice of packaged chips and popcorn was utterly ridiculous for first class

Our flight left on time and we arrived a few minutes early. Great service!

Overall, I had a great flight on American Airlines. The only compliant that I have is that my gate changed 30 minutes before boarding the flight. This was annoying because I had a connection in Charlotte and it's a very big airport.

Our flight was delayed 45 minutes and we missed our connection, while we were able to get a flight the following day the voucher for food did not work.
