Great overall experience and use of the Delta One lounge was amazing!
10.0 ExcellentAvery, Nov 2026
Great overall experience and use of the Delta One lounge was amazing!
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.
