Delta always provides stellar service. I am always impressed and will try my best to travel via Delta if I can afford it.

The flights were on time; all went as expected which is a big positive! No delays! There was no food or drink service in any legs, which I understand due to the short flight time.

The Delta assistsed services were awesome for my aunt. So very helpful.

Probably not the fault of Delta but there was delay after delay after delay and I ended up getting home 4 hours later then I should have at 1:30 in the morning

Staff was exceptional! Everyone was kind, professional and friendly making the trip very pleasant. Thank you!

Very late arrival at PWM. Late jet getting to ATL. Equipment problem with aircraft - could not get enough water onto plane., Another delay getting FAA approval for flight with bottled H2O. Not the crew’s problem.

A little bumpy ride . No food was being provided due the the turbulence. That was ok it was a short flight to my standards.

Pretty standard flight. Delta has a good selection of movies.

The flight was so late that I had to change connecting flights, turning a five-hour trip into a fourteen-hour nightmare.

Despite being delayed, we would still give a high score for this flight experience. For the first time in quite some time we had excellent customer service throughout our entire round trip. The flight attendants were the most polite we have experienced in our last ten flights at least (non of which were Delta and include business class). The food offered was a better selection than most—we just didn’t have any of it. Overall, almost as good as flying used to be. Thank you to Delta.

Good, our flight was delayed but that was totally out of their control due to weather and a presidential visit.

I initially boarded in a very comfortable and large plane and was told there was a mechanical issue with a waste receptacle. We sat on the plan for a good few hours, then were told we can deplane and that we would take off shortly. Delays continued and four hours later my flight was cancelled, and I had to quickly rebook another. The flight I rebooked was also delayed, and I when we boarded, I wound up on a small plane in a middle seat for the 6-hour journey and it was extremely uncomfortable. No issues with the staff in any way, just the overall experience of the delays, cancellations, and downgrade in comfort on such a long flight. It is significantly impactful on how you feel post travel and I was exhausted and sore from the experience.

It was pretty good, they give a small blanket, neck pillow and earphones. The only bad thing was not big enough leg room for your bag and feet. They gave us a snack, dinner, and breakfast on flight and food was good considering it was on a plane

I bought this ticket for my daughter. She had to pay for her carry on bag to be checked. My understanding is that transatlantic flights included carry on and personal item The nickeling and diming fo legacy carriers has stooped to an all time low. So sad.

The flight was delayed by two de-icings. The seatbelt did not work correctly. It did not stay tight.

The seats on the aircraft are like sitting in a rock. During the boarding process they recognize Active Duty Military, why don’t they recognize Retired Military. I’ve always preferred Delta, this flight confirmed why I still prefer Delta.

It was literally one of the worst travel experiences ever. My flight got delayed by over an hour and there was no communication of this from the gate staff. I realized it by checking the screen periodically. Once on board the flight attendants continued to serve alcohol to a man who was clearly already drunk and that was making a bunch of commotion. Never again will I fly United!

At least the delays were short. Business class, even in the new planes is very crowded now with crappy tray tables

All good except paid for wifi that did not work

Flight cancelled due to fog. No other flights available for 36 hours. Directed by United to book passage on another carrier, and submit receipts for reimbursement. Did that. United now states they will not reimburse. Currently out 2 grand.
