The flight de-boarded after being informed of a 3 hour delay. The gate agent said we could go to lounge. The flight ended up boarding 20 minutes later and I missed it.

I love the e fact that the staff communicated swiftly when my flight was delayed and gate number changed

We had a mechanical delay which made us 90 minutes late (9:30 PM) then land and put into the penalty box because a plane was in our gate? What the hell! We should get priority.Damn American.

The seats were extremely cramped, with very little legroom or personal space. There was no room left in the overhead bins for a backpack, and the space under the seat in front was so limited that I could barely fit my bag underneath. Overall, the seating arrangement felt very uncomfortable and overcrowded.

weather delay of almost 2 hours then we landed and our gate wasn't available so we waited another 30 min

Delayed flight more than I hour. When boarding we spent some additional time on the plane before takeoff ....

The flight was delayed significantly and we sat on runway after landing for awhile. Best thing was the flight attendant, Jenny, in first class, who was very professional and attentive. She was excellent - the rest of the flight was not.

The flight attendants were extremely sourly and borderline rude. I did not feel appreciated as an AA customer once.

I had first class itinerary, yet they put me boarding group 5! I spoke with the gate agent though, and she let me board in Group 1 like I should have been assigned. Would've liked water

The entertainment box wasn’t working. The food was mediocre. The fruit was warm. The tiny salad was good. The champagne wasn’t cold. I really expected more from First Class.
