Great Team on the flight. I was the only one in the exit row and the flight attendant just sat down and we had a talk about my responsibilities sitting in the exit row. It was very humorous. During the flight every time one of the flight team members made eye contact, they smiled. It was a small thing, but it was a friendly environment.

Great flight from Charlotte to Orlando. In flight wifi and entertainment was not working til 25 minutes were left in the flight would be my only complaint.

More room. International flight - by the time you put your purse and shoes under the seat in front of you, add in the pillow and blanket they give you- makes for tight fit.

Boarding can be more efficiently done by having the back row passengers board first. This way, the other people do the have to wait for front row passengers to load their luggage in the overhead cabins. Food is simply pathetic for the price I paid. Cleanliness is simply poor; my seat was full of crumps.

Overall good. Tight connection in DFW because of gate unavailability upon landing.

Airplane was cold. Flight attendants were rude. Phone charger did not work. No food available.

The flight was very smooth, crew were fantastic but food was lacking.

No food, no entertainment. But the flight was really short so maybe they had to skip drinks. I was able to board early ONLY because I am old and decrepit and they let me pre-board. I RESENT your dumping us into category 9 if we do not pay up. And when I paid for a seat I was STILL given 9. The pre-boarding helps. THIS flight was exceptionally smooth, please congratulate the pilots.

The best thing about AA is that the onboard entertainment allows me to watch on my iPad. This was not working. USB ports were not working and the flight attendant said they often don’t work. The flight attendants, one in particular, were uncaring. I was very disappointed.

I liked the onboard entertainment that allowed me to watch on my iPad.
