Flight was delayed three hours waiting for the flight crew, even though the plane was at the gate for the scheduled departure

It was a good flight. Of course it was full, but it went well.

We sat on the plane for 1 hour because the airline was short handed could not be unloading.

Seats in coach aren't padded enough for a 6 hour flight

We are gluten free, there were not any available complimentary gluten free options.

Flight delayed 3 times. We were directed to go to a gate across from our gate. The plane wasn't there yet so we had to wait for it to arrive, then deplane everyone and then wait again for the plane to be cleaned. After 45 minuites we were allowed on the plane. The first plane had mechanical issues. The 2nd plane must have had bathroom issues because we did not have any food service whatsoever. No snack or beverage. That made for a long time not to have anything considering that we had just made it to the original gate and we had no time to stop to get food or a drink. Then we didn't want to leave the gate to get food because we wouldn't know how much longer the delay would be. Then the next gate change. Had we been told that the total time would have been aprox 45 min later we would have left to get food and a beverage. We had to wait again for the okay to the pilot to take off so we were on the runway for another 20 min. Overall, we were delayed over 2 hours which felt like 4 hours.

Lots of weather delays that were poorly communicated and managed. I get there are weather delays but they didn’t make it clear what was happening or comfortable on the plane

Let me start by saying our connecting flight was cancelled for a maintenance issue but American airlines blamed it on the weather. When rebooking my flight the lady said it was because of maintenance. Our incoming flight wasn't delayed at that time. So we could fly into bad weather but not fly out of bad weather??? Doesn't seem realistic to me. Then our incoming flight was delayed 3 different times. No meal vouchers for lunch or dinner. Just to be on the hottest plane I have ever been on and they didn't serve water or snacks. Never again! Take this warning do not fly AA ever. There are over 3,000 people at the Miami airport due to 27 cancellations. The flight attendants and pilots should be fired.

Me and my husband experienced very bad in American Airlines. We missed our flight going to Doha. The American Airlines was delayed we arrived already 10:27pm. Supposed to be 9:40 pm. So what they did they rebooked our flight and they gave us a hotel. When we arrived at the hotel the front desk said it was fully booked already. Oh my gosh! I said why did you accept the booking if it's fully booked. The guy said that's American Airlines they just book even it's already full. That's 2am already, we have nothing to do so, we decided to go another hotel. We pay the room, food and taxi. Pls give an action on this matter. Refund our expenses and give us more compensation. Not only our room, food, taxi but also our efforts, tiredness looking for a room that can accommodate us.

Horrible. Flight was delayed and very bumpy. I was super unhappy
