Flight was operated by Virgin Atlantic and it was up to their usual high standard. Minor grips about some issues, but they are really first world issues and as a whole, was an excellent flight.

Flight was operated by Virgin Atlantic and it was up to their usual high standard. Minor grips about some issues, but they are really first world issues and as a whole, was an excellent flight.

I am extremely disappointed that delta internal pilot manuals now refer to the Gulf of Mexico as the “gulf of America”. You can bow down to the Orange turd on your own. I will never fly delta again

Delta One upgrade it would have been great if my tray extended (it was jammed and wouldn’t pull out), seatbelt had too much slack & my little cabin door didn’t close properly

I paid for a business class ticket on Delta. It was sourced to Virgin Atlantic. They changed out the aircraft which had fewer upper class tickets. Even though I'd checked into the lounge, was receiving alerts via kayak about the delay and changes; no one informed me that the seat would be changed - until I attempted to board and was told that I would have an economy seat or they could search to put me on another airline. Even the flight crew were informed of this change (10 passengers were bumped out of Upper Class) around 2 pm (1400) time. Hours would have helped to consider alternatives instead of making a last minute change. There needs to be compensation from both Delta and Virgin given this change in service/experience.

Wasn't a Delta issue I don't think, but seems there was a Delta flight at each of the 2 Dallas airports at the same exact time, both to Atlanta. I was evidently booked on the one at Love Airport, but the Carey transport shuttle took me to DFW instead and I ended up missing the flight by just a few minutes. Was able to book a Southwest flight from Love Airport, but was a big loss of time and an inconvenience.

Every single flight that we got on was delayed by several hours or more. I honestly didn’t think we would get out of Atlanta because our flight was supposed to leave at 7:59 and it kept getting kicked back further and further. Delta stands for Don’t Ever Leave The Airport!

Great. I had to modify a flight. That was easy and free. Thank You

I noticed that the planes seem to be outdated. There was no entertainment per se. Also, the waiting area did not have any working electrical outlets

Original flight was cancelled and when i was rebooked by the airline, they couldn't seat me in the same type of seat as I had originally booked (went from window/aisle to middle/middle and one was a bulkhead seat, and other wasn't in the same class)

Lady Pilot was perfect in every way wheels up to wheels down communication, professionalism, excellent on time departure and on time arrival, excellent communication! Fantastic job with Superb attitude!!

Very turbulent trip made it pretty bearable, plus the lack of refreshments served and the lack of any air conditioning before takeoff which took an hour or more.

Flight was late - I was downgraded from first class to coach

Not good - outbound flight was delayed and missed my connection even though I got to the gate after running through the airport - the agent would not let me on because the door was closed (flight had not left). There was no notification from United - overall experience was very disappointing. Additionally, I was downgraded from first class to coach on the alternative flight

The flight was on time. I generally don’t drink or eat on short flights and the seats were good and the flight attendants were friendly. That’s all I expect

Movie selection is good. Crew did not understand mileage program and were no help. Sick later. Food?

Staff on board was excellent. Positive upbeat helpful- like it used to be.

It was nice to have gotten up upgraded to first class with a meal on a three hour flight

For an expensive flight to another country, United has a lot of nerve serving pretzels and no meals (unless, of course, you want to buy something to eat). Unacceptable.

The food is terrible. The same pasta or chicken with bad taste and presentation

United have really come back. Airport and boarding process is clear and good, app and information also very good

The pilot greased the landing and the crew was fantastic.

I bought wifi and most of the flight could not even use it my apps would just spin. I couldn't even listen to music. super frustrating.

delayed due to weather. Could not communicate with family since the wifi was broken

Experience was good, however I had a delay due to weather happening and had to re purchase a seat on a new plane for a higher price (could be my own issue and misunderstanding) but other than that situation. First time flyer (by myself) was terrific!! The last from ORD to ALO didn't have wifi, but it was only 45 minutes so I'm sure that was part of the reason. Overall my experience was great! Next time I will remember to buy tickets with longer layovers. The delays really saved my overall anxiety. :)

Flight was on time is the only good thing. Person loading the plane called 1-6 to board at the same time, made it chaotic. Plane was too small for even putting backpacks in overhead. Seat for normal sized people were too small. The WIFI didn't work. When we landed had to wait because not enough ground crew.

Did not understand a single word the attendant said on the pa system. I was glad it was not an emergency.

Gate was overcrowded. Gate agents performed very well. Flight crew was top notch! Efficient & professional & courteous. Both meals not thermalized well. Dinner main dish was actually cold in the center. Almost inedible. Breakfast sandwich was lukewarm.

The boarding was as always, the crew tried their best but not enough. The food was a disaster I had dietary restrictions that were half met because the company did not loaded the food for the flight. The entertainment screen was fine but content was not and also they removed the free messaging option from the flight and they charged 30 dollars for that crappy bandwidth. This flight is not worth the cost and the company is going down on quality.

Awful. They won’t help me with anything. I booked on American but they abdicated to Iberia. The ticket was overpriced. Everything negative

it was fine, decent flight... dont get food besides cookies or pretzels so not sure why you ask about food. same for entertainment..
