Flight was extremely hot and they made us check our bags when the space was nowhere near full

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.

It was the most un-special flight experience in my life.

The flight changed gates multiple times and flight had to be delayed multiple times

AA is flying sub par aging 787's to Tokyo. I fly other 787's long haul and these are at the bottom. Seats don't work well, tray tables don't work well and were dirty. The flight was great, the plane was not.

Where do I start!! I was delayed with my flight from Dallas to Tampa. On the way back from Tampa to Dallas the flight was delayed over 4 hours+. I was put on another flight that was also delayed but not as long. Traveling on American Airlines is becoming exhausing.

Meals were not so good. Snack between the meals was very bad. Like Japan Airlines, they could eliminate the snack and make the second meal much better.

Crew was clearly not loving their jobs at any point of the entire trip. Flight back from Mexico, I asked if they had food for sale for the 2.5+hr flight and they did not have any. The business class trip to Mexico also had noted that the catering company forgot to load food. The last leg of trip back had a similarly unhappy crew, a broken toilet, and my seat was broken (reclining would not lock which made landing a crossfit like event). This was a bad week for AA.

American airlines suck they delay the flights all the time made me sleep in an airport because my flight was delayed and I miss my connecting flight

We arrived 4 hours early and still almost missed the flight because they weren’t able to access one of the boarding tickets. They then sent hour bags late and we were all of our without clothing and eventually had to take an expensive cab back and forth to the airport as they wouldn’t deliver the bag which arrived late at night that day and we would have to wait until noon the began day (messing up a second day of plans). Also, all the food has dairy or pork. No vegan or even vegetarian option in the flight—even for purchase.
