Seat was VERY uncomfortable. Flight was delayed and then boarded slowly. The crew was super helpful with boarding and supporting maximizing the luggage in the overhead.

Seat was VERY uncomfortable. Flight was delayed and then boarded slowly. The crew was super helpful with boarding and supporting maximizing the luggage in the overhead.

Crew at the gate was very crabby and not at all polite. The plane was very hot the entire flight. And the seat cushion was very worn out.

Incoming flight was delayed, delaying boarding. It then took 30 mins to take off. Took 20 mins to get to a gate because they changed the gate last minute, crew weren’t ready so there was no one staffed to work the jet bridge. Boarding was so disorganized as is usual with American because everyone just stands around the gate regardless of boarding group.

Early morning flight and no food in First Class except a "salmon" box. No thank you. Was informed before take off by Captain that the plane was not serviced before we boarded in Phoenix. How does that happen? Need more frequent additions/turn over on the Entertainment. Thanks

Moved to earlier flight which unexpectedly had maintenance issues initially indicated as quick fix to ultimately plane changes. Moved back to original flight, also delayed. In all cases customer updates and communication very unclear, no updates on drivers for delays.

Flight was delayed. No urgency by American Airlines team to assist those with connecting flights. It was basically you are on your own to run through the terminals to try and make your connection. Thanks, Mary

I have never been assaulted they way I was today in Charlotte - shame on American

One of our group members was struggling to walk. In Charlotte we asked for a wheelchair and she was accompanied by Desmond. I was impressed by his patience and attention. In Boston she received the same service. I didn’t get the name of the helper but she went above and beyond in assisting us. A great AA service

Delayed 24 hours. Should have called it much earlier They provided quality accommodations, food vouchers etc. FINALLY The issues started at 8 AM and they cancelled the flight at 11:30 PM, with no plans for a new flight.

Better snacks but flight and crew were amazing on this flight
