Customer service at the gate in the flight was exceptional. On time. Aircraft and seat was decent. Thanks Delta. 💗

It was terrible, if they ran flights on time it would make a big difference.

Delta seems to be improving in many areas, except they are super bad with the food available. Bring back normal food service on long flights.

I actually received a notification from kayak on email but not one by text from Delta when my departure gait changed and I almost missed my flight

New boarding doesn't make sense. Filling front first is slow.

Delta flight was great from the check in all the way to arrival. However, I had a very bad experience. I requested a wheelchair and the wheelchair employee that went to pick me up from the plane in Boston to bring me to the baggage claims told me I have to pay him. I was under the impression that it was a free service and I usually give tips but the person forced me to pay and since I said no because I was upset with his demand when my daughter walked in to pick me up he demanded payment from my daughter who paid him thinking maybe now it is a charged service.

Horrible. Grateful to be alive but spent 13 hours at airport only to return back to my familys house and flight changed to next day. They tried to fix a part on plane, had no back up plane and after 10 hours , reattempted the flight and it STILL wasn't fixed. We got a meal voucher and rescheduled flight but there should be some other compensation for the 15 hours spent in airport

It was reported to the passengers that Delta failed to schedule the crew properly. This error caused the pilot to show up about 30 minutes late. All in all Delta's inability to take care of this basic function resulted in about an hour delay.

Canceled last minute. Also canceled another flight that my brother was supposed to be on. Delta is horrible now. Never flying them again.

My seat was changed at the last minute and I was moved to the last row, right next to the bathroom despite selecting my seat well in advance. I was also made to check my carry on due to space but when I got on the plane there was significant empty overhead space. Picking up my carry on from the luggage carousel added time to my trip which had already been extended due to delay.

Flight attendant walked away once they landed and we were forced to wait another hour after an already 3hr delay.

they should make XXL people buy two seats. sitting next to a person that was half on my seat and could not even buckle the seat belt, so I had to lean in the isle the whole trip.

Promised lounge access, gate agent didn't allow us entry.

The flight was great, and I have never ridden in first class previously so I don't have any practical knowledge of the norm. The flight out to DFW was delayed and I sat in economy which was as expected, not nearly as spoiled as I was in first class which had more general room but that is par for the course. I have no complaints and will wait until I fly American again before I can make a valid improvement. I will fly American again in the future.

The departing flight from Newark to Charlotte was fine. It was the returning flight from Charlotte to Newark that was awful. We had scheduled an 8:35pm return flight time. We got delayed TEN times all the way to 5am in the morning! We were told over 4 different excuses as to why the flight kept getting delayed. First it was the flight crew needed to rest, then it was something technical with the plane, then it was something with air traffic control, and finally it was because they couldn’t find a captain and had to wait until the morning so the captain could get some rest. It was terrible sleeping overnight in the airport. They offered a $12 meal voucher. That was it! And the only place open in the middle of the night was Dunkin’ Donuts who didn’t even accept the voucher. They should have cancelled the flight much earlier on in the evening instead of just stringing us along hour by hour with more delays. Not professional and unacceptable. There was no refund for inconvenience. I probably will not be flying American Airlines again.

This leg they tried and did well with what they had to work from.

Due to an issue with the plane. We waited almost 2 hours to take off. The service reps were great. We had a longer layover but was able to run for it and catch our flight. This also happened on our way out. Maybe the planes need a good look over. The people who work front desk and flight attendants are the best

Domestic airlines have really fallen from what they used to be.

The free internet access did not work, so we had to purchase 2 Internet packages. Flight attendants were not proactive in checking in with first class patrons

11h50m total delay. Had to switch to another flight that was still a 7h30m delay.
