The crew was dis respectful even in business class. I will not recommend AA to anyone and will also fly only when there is no choice

The gate agent in BNA got irritated with a lady for asking her about standby's and refused to hand out assigned standby tickets to ANYONE until Group 6 . She punished all standby passengers because of the one lady she did not like. When we boarded she said thank you to everyone as we scanned our boarding passes except the lady in front of me. Very petty and unprofessional

The flight from DFW to SAT started out with a 2 hour delay. It was a five hour delay with no real explanation as to why. In addition, the time of arrival kept changing from 10:00 pm to 11:00pm to sometime after midnight. Driver picking me up in SAT was as confused as I was. Flight attendants were patient thank goodness since folks were a bit upset about a 2 hour delay that stretched into 5 hours.

The boarding process, airplane, entertainment, beverages and crew were very good. But the food left a lot to be desired, especially for business class. I had a chicken breast that was tough and rubbery, with little flavor. It wasn't even up to the proverbial "banquet chicken" standards. Very disappointing. There was only one offering of bread, OK, not a huge deal, but it's a nice touch to be offered more. Similarly, other airlines' crews come by to offer more drinks, though the crew responded when asked. Good flight overall, but the food just wasn't up to the standards you'd expect.

No AC, no beverage service and no explanation from the captain. 4 flight legs in 2 days with no internet service.

The gate experience at LAX was abysmal (same for the arrival experience two days prior). Despite the LAX -> SAT schedule of two flights daily, our departure gate was at a smaller hub that we had to be bussed to from Terminal 4. Fortunately, I arrived at LAX extra early and had time to spare, but if I had not known, I might have missed my flight. I looked at the LAX airport map in the AA app and there was no indication of the additional boarding process. Lastly the gate area we were bussed to was crowded with limited food and beverage options. On flight, the fight attendant was hospitable and attentive, the flight was smooth, and AA's free (and working) wifi for AA members were all on the positive side.

Got home at 3am after deboarding the plane. No compensation offered by American

Awkward carry on process. Forced to check all carry on. No overhead space of worthiness. Left delayed, but made up the time. Crew was amicable.

Canceled flight for unknown reason after numerous delays and only available flight was the following day yet no compensation. No weather problem. Then had to fill out form to get refund. American used to be a quality airline - no more, very sad!

entertainment choice was excellent for both movies and audio. Food was quite good. Staff was excellent and flight was on time and smooth.
