Airline reviews

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.

We sat on the runway for over an hour before departure. That was unwelcome.

Flight delayed four separate times. I’m now one hour hours late to landing.

worst flight ever from Delta, it got delayed and kept on delaying..

Everything went smoothly, although the usual gripes about airline travel were still present: the boarding process is inefficient, the snack selection is limited, and so on. Since there was extra space on the flight, the gate agent rearranged many people's seats to put people on the aisles and windows, leaving the middle seats empty, as much as possible, which was pretty great.

While they turned off most cabin lights to allow people to sleep, I was bothered by how bright the side lights still were. It was still quite bright for me in a window seat, when I wish I could have slept!

One of the flight attendants was a little cranky. I appreciated the free wifi and plug to charge my laptop

WiFi didn’t work most of the time. The usb chargers would work only occasionally for 5 mins and wouldn’t charge after that. Had to keep trying repeatedly at each of the seats in the row.
