Horrible. No AC. No Air inside the plane. We had to deplane twice! It is late almost 5 hrs in total. I almost passed out and about to call 911. I asked the crew to be honest and open the door. The lady next to me was lay down in the floor due to heat and no air inside the plane. I got headaches, can’t wait the replacement flight about midnight Dallas time. I end it up rebook for next day flight and stay overnight using my own pocket in a hotel nearby due to headaches and can’t breath. I still have a headache this morning. Still not decided yes how to file this issue to AA and/or FAA.

The flight was ok, i understand Houston-Dallas is a short distance. The plane is really small: no TV, no snacks, but other than that, all was good. We had a bid delay but luckily it did not affect my connection

Forced to check bags. Crew uninterested in collecting trash. Unclean seats.

There's nothing I liked about it. For first off I scheduled this trip two weeks in advance then they delayed my flight which messed up my whole trip. So I scheduled it for the following weekend thinking there won't be a delay and guess what as soon as I got to the airport we said in the airplane on the tarmac for an hour and a half. Not only was it delayed I missed my connecting flight meaning I had to stay the night at Dallas-Fort Worth airport sleeping on the floor. I will tell you this I will never fly American airlines ever again I have had nothing but horrible experience with them and I just throw money at them

They changed my seat from one that I had paid for as an upgrade to a regular seat at the last minute.

Very aggressive and unhelpful ground crew. Wanted to check my hand luggage for 3 flights. I had lots of delicate items and computer equipment. So the silly lady wanted to rebook 3 international flights because of a carry on. What nonsense. The baggage handler suggested I put it under my seat - so I did. And this was during the rebooking chaos of the Microsoft crash. She was the most arrogant annoying and aggressive ground staff member I’ve met in 20yrs. (AA flight out of Houston).

Left from gate 30 minutes before flight. Never been late to a flight ever. It says 15 minutes before explicitly on the ticket.

Was as expected. Good leg room on planes - much appreciated.

I know that there is nothing than can be done about rude customers. I did find a couple of them were very rude and inconsiderate In my case the guy who was sitting in the same row as I was in, was trying to watch a movie with no headphones, a crew member did ask him to turn it down or off (thumbs up for that.) Another thing, as we were about to land another young man must have taken his phone off airplane mode was talking with his friends and using fowl language which I found inappropriate to the ppl who were sitting in the same row as him and other ppl around him. I understand how no one wanted to address this person and not get involved. We all just wanted to get home safely with out any incident.

The food service was limited and not good. For a seven hour flight they could do better.
