Everything was fine except the entertainment was not working for half of the flight.

No one fussed at me about my pap machine as a 3rd pice on the plane. Boarding was pleasant and smooth. The boarding agent in Anchorage was a fun character- he could be in a movie. :~) The on-board crew were downright pleasant. No militant attitudes on Delta. Like all planes these days the seats are too narrow for standard Americans and at 5’2” there is barely enough leg room. I don’t know how tall people fold themselves into the seats. But that’s nothing specific to Delta

I want to single out flight attendant Mitch who was in the Premium Economy section. When my wife’s hearing aide dropped through the cushion under the seat he was able to locate it and return it to her. Food was a different matter. Dinner was fine. Breakfast was another matter. They had a yogurt dish that the ran out of and the alternative was not very good according to those we talked to.

Excellent flight, the planes were newer, they did a nice job with boarding, great service overall.

5 hours of delay that could've been much shorter if Delta had taken the 1 hour delay they imposed on the flight before boarding to run any of the plane checks required for flight to find the hydraulic issue that required nearly 3 hours to fix. $24 of meal credit buys a sandwich and a soft drink. Poor communication within the terminal about what gate we'd be re-boarding from and when we'd be re-boarding.

Great flight! Only complaint I had was that I didn’t get breakfast that morning because I don’t eat eggs for breakfast.. I ate an energy bar I bought in the airport which I had never done before. Otherwise, another great Delta flight!

Delta is a premier airline so my expectations are most always met.

Seats are much much more comfortable than United, which is what I usually fly

Logan airport construction meant that boarding was chaotic crowded and delayed

Everything was good except when we're on a 6 hour flight at dinner time and all they offer as part of the fare are little bags of junk food, it's disappointing. Bring back food service without an added price.

I liked the choice of lemon ginger tea. I think stewardesses can be more considerate of older people needs.

It was great, I’m very grateful for the pilots and crew flight attendants for everything.

Everything was great. Only thing that could’ve made it better was buy on board options for hot food, but the snacks were decent. The flight attendants were great. I had no complaints. I was able to make it to my destination safely

Overall it was good. I missed my connection but I was put on another flight.

The attendant were friendly. I suggest you have a medical attendant on board every flight so that in case someone is sick , he/she will help them.

The woman gate agent in Phoenix was none too sympathetic about my check-in process as I am relatively new with using apps. I almost did not get on because she said I did not check-in. I thought I had via Kayak where I purchased a very expensive ticket. Lesson learned but to be told I may not get on as a matter of factly was difficult to hear.

Overall a very poor experience - booked premium economy tickets but due to last minute flight delays , all my itinery went for a toss and had to fly economy class with no access to lounge or any compensation by united airlines to make up for the flight delays . i had expected better experience than that from united.

Boarded plane and then delayed 1.5 hours while on the plane

Survey sent before we actually left. Delay after delay. Now a crew problem.

I love flying with United. Unfortunately, I flew on an older plane with minimal upgraded technology (no Bluetooth functionality or handy charging ports). Otherwise, the flight was great and even arrived early.
