Flew first class so everything was great. But maybe because the flights were red eye, no meals were served, just chips. I flew Alaska Air 1st class at 9PM (2 hour flight) and they served beef short rib sliders!

Flew first class so everything was great. But maybe because the flights were red eye, no meals were served, just chips. I flew Alaska Air 1st class at 9PM (2 hour flight) and they served beef short rib sliders!

Had to change aircraft due to a faulty door. Surprisingly it only caused about an hour and a half of delay. Delta handled this situation as well as can be expected.

Awful. Flight was continuously getting delayed and gates kept changing without any reason. Flight was delayed for more then 3 hours

Paid premium for Delta only to be on safe but tired old 767 with ancient cabin in mediocre condition. Poor wifi and horrible inflight entertainment. Hardly a premium experience. Should have flown SW and had fun flight crew and no pretense

Our flight to Zurich was delayed by almost 3 hours, so we missed our next flight. There was no indication it would be delayed this much. We were told the gate had changed and then it apparently took over 2 hours to load the "catering" on the plane. We were not compensated in any way for the trouble.

Rated entertainment as Mediocre as there were major problems with the Infotainment system that took probably a half hour for them to fix.

Your crew could maybe answer the call bell at least one of the times I pressed it. I pressed it first time with 2.5 hours left in our flight bc my partner was hungry and wanted a sandwich. We finally got the sandwich with 40 mins left in the flight.

Delta crushed it. Flight attendant in first was attentive and just never stopped. Honestly one of the best domestic flights I’ve been on.

They were an hour late and they didn’t have my wheelchair for me

The Flight crew didn’t serve us until about 1.5 hours into the flight because of turbulence but after it ended it was fine to move around. They served us water only and snacks and then NEVER, NOT ONE TIME came through to collect trash until right before landing about 1.5 hours later. There was absolutely no need for that. They crew was just standing around talking and visiting with each other and really never tried to see if we might want something besides water or even try to come pick up trash. This is VERY unusual for a Delta flight but it was not what I would have expected for a 4 hour flight.

There was no screens on board AND the WiFi didn’t work. My seat was broken and couldn’t recline so I couldn’t even sleep. The flight attendants didn’t offer anything to make it more comfortable. It was such an old cramped plane, when the person in front of me reclined I couldn’t even open my tray table. All the United ads talk about guaranteeing everyone gets a screen!

I’ve had a couple flights this week on United that were delayed by an hour or more

Great! The plane was decently sized and comfortable. The staff was nice and there was great in flight entertainment

Last minute gate change nearly caused us to miss our flight. Change was not announced or displayed in the main board at the old gate. Terrible communication. When we landed we had to wait 20 minutes because there was another plane at the assigned gate. Not the crew’s fault, but adding 20 minutes to a 45 minute flight sucked.

delay several times and wait extra long to board. no entertainment service because there are problem for some rows. always encounter some delays for the last flight of the day.

The flight experience was very good! Especially the United Club!

I was not able to buy food in the flight. They refer to include your Credit card in the APP, and if you are not from USA (i have a credit card form Canada) it is not possible

The flight from Ottawa to Chicago took a lot longer due to DC in Ottawa. We got to Chicago and went to our gate to catch our flight. We only had nine minutes I found that very stressful.

Good boarding. Crew started quick with drinks and food. They came around several times for trash which I really liked. Other than turbulence due to storms in the area, flight was great.

The control panel for the seat back screen did not work at all after takeoff.

Good flights. Departure and arrivals were on time. DFW was a little problematic in that the Skytrain without prior notice bypassed the Echo terminal so that delayed my arrival at my connecting flight.

Because I can’t stand very long in one place, I was allowed to reword.

5 hour flight - full flight - not enough room to use my computer - slightly delayed - Admirals club was excellent quality food, drink made up for flight seating. No food offerred on flight, you ahd to prebook.

Excellent- plan was barely populated. I cannot remember a flight where I was able/encouraged to stretch out!

Great flight. Boarding was efficient and quick. On time departure and smooth flight. Flight arrived early at destination. Good experience.

Had technical issue which delayed the flight period. Flight crew knew there was 5 passengers that the connecting flight was within 15 minutes once at the gate. Rather than identify the 5 passengers to assure they got first. The flight attended mentioned it but didn't assist to assure passengers with connecting flights off first. This caused a hardship and our party of 3 missed the connecting flight.

I don't like that I have to pay if I want extra leg room. The seats are so expensive; I sit in normal seats and my legs and knees cramp the entire flight. I never feel comfortable on AA flights.

Flight was delayed at departure due to weather and the need for de-icing. The flight was smooth but there was a delay at arrival due to weather. We were in a hold for 20 minutes or more. The flight arrived more than 30 minutes late. Airlines have no control over the weather and I'm glad that they follow all safety procedures. Had to wait a long time for my checked luggage. Whole process was slow and the bags arrived wet due to the rain. The onboard wifi and entertainment access was spotty and the signal was dropped several times. Otherwise the crew was great and friendly. They tried to get everyone's bags stowed and seated so we could take off.

Regarding the boarding: it needs more efforts to make it more convenient

Deicing in Denver took forever and I almost missed my connection. De-ice faster! Not Americans fault.
