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 helpful. Plenty of food although not great but ok. Good time.

This long-haul international flight was the most comfortable among any of the same kind of flight operated by an American-headquartered airline - second to none!

My requested wheelchair never appeared. So many entertainment choices yet, I found little of interest and no internet option to search on my own. Both were minor issues.

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!!

Delta is better for short flights and very low need for customer service. Avoid for longer flights

I notice that every time I fly delta or any American carrier, the staff seem tired, overworked, and not at the service level I’m accustomed to in Asia. They frequently crash into my arm when coming down the aisle. Food is shoved at my face with no greeting or verbal cue. The food portions seemed much smaller than usual and didn’t see much wine or beverage options. This is comfort plus? The plane was old and tired. The bathroom was dripping with mineral stains after a long lack of cleaning. The power socket did not work, although the USB output did. I really wonder why I’m flying Delta, I think it’s time to switch to ANA.

I was sitting at comfort +. One of the Asian male crew was so loud when he delivered service. When he asked questions or what food you need, he was shouting. He must be a prison guard before going Delta.

I was surprised to have such bad service since I feel Delta usually does a good job for long haul flights, but this experience was quite bad. Onboarding was chaotic, the flight was uncomfortable as the cabin temp swung from very cold to steaming hot, and the attendants were rude and inattentive.

Why, on an 11+ hour flight, is the food being served at a speed resembling a 90-minute flight? Flight crew practically threw our food at us, then cleaned it up before everyone was done. All, presumably, so that they could retreat away for the next 7 hours to be completely unavailable. No additional beverages were served for hours. Delta is supposed to be the premium American carrier, but on this flight, it made me wish I was flying someone else. Also, the “upgrade” to comfort+ is a joke. It was worse than Japan Airline’s lowest level economy class. Literally no comparison between these two airlines. I wouldn’t fly Delta from Tokyo again unless I absolutely had to. Very disappointing amenities and service!
