Airline reviews

Both of my flights to and from JFK experienced significant delays. Most notably, my first flight was delayed by six hours due to crew members being affected by delays on a previous flight. While I understand that disruptions can occur, Delta’s staffing and operational planning should include sufficient contingency measures to handle situations like this rather than placing the full burden of those delays on customers. Additionally, the $12 meal voucher offered as compensation was inadequate, particularly given the high cost of food and beverages at the airport. Considering the length of the delay and the substantial inconvenience caused, I believe more meaningful compensation would have been appropriate.

Comfortable seats. Nice service online. Short flight, so not a lot of time to enjoy.

The flight was done by SkyWest only WIFI no entertainment center are available on the CRJ

Delta is always late. Ruined our first day of a short vacation. Timing is important. We pay to stay on an itinerary

We never made it on this flight because we missed our connection due to o delayed flight from Jackson.

We got stuck on the tarmac taxiing after landing early so we didn’t get off the plane until an hour later than we thought we would

It was okay. We were delayed for weather reasons, but the pilots and the flight control staff figured a way around the storm and were able to get us to Los Angeles safely. Not all the staff members were polite, but the entertainment on the flight was good.

I am a Diamond Medallion Delta traveller and this was a disappointing flight. They allowed half the flight to preboard before Delta One and Diamond Medallion. Once on the plane in my Delta Premium Select seat we were not given any welcome or greeting. Throughout the flight the flight attendant also did not make us feel any sort of special service or attention and even rushed us when she did bring us a snack to pick in the dark not even offering a light to look at what it was -- she was overall not helpful and not accommodating. for the extra cost of the seat it was honestly not a special experience this flight. heads up that even the warm cookies are now packaged. I ate nothing. There really was nothing that was special, stood out or exceptional. Luckily I mostly slept. But I was disappointed and question if I may try a different flight next time I go to Tokyo. The last few Delta flights have been less than great. which makes me very sad.

Crew was real good, flight was smooth and came in early.

Love me some Delta. One of the few airlines to recognize and support veterans. Easy boarding, flight was on time and arrived early and the flight attendants were excellent on this flight.
