The helpful attitude of the staff, and being a wheelchair passenger everyone was helpful and understanding. The trip was made comfortable by the upgraded seat which was given without my request, that was a great surprise. Thank you Delta.

The helpful attitude of the staff, and being a wheelchair passenger everyone was helpful and understanding. The trip was made comfortable by the upgraded seat which was given without my request, that was a great surprise. Thank you Delta.

Everything went well with the flight. But one of the flight attendants had on inappropriate pants. She had on an old worn out pair of sweat pants. The back seam was unrivaled and should not have been worn for work. If I had not seen her in the airport with the standard type of luggage, I certainly would not have thought she was working for Delta. Not a good look at all for representation.

Great!! I haven’t had a bad experience with them.

The plane was one hour late cause they were doing some reparations with us on the plane no mention I was in the first seat and the door was open the entire time with 8 degrees! The plane was totally dirty no mention old ! The staff was nice but no put together, the attention to details and passenger experience is missing and i always travel first !!! Is better the lounge than the plane! KLM/air France every details is taken care maybe you need a creative creator or experience client need asap was terrible and not memorable for the price that I payed very dissatisfied

Boarding super slow with people allowed to linger in aisles

We flew early evening on New Year's Eve. Our plane was less than half full... Great for the passenger experience -- not so much for the airline lol. Comfortable, spacious, smooth flight -- and early arrival!

First time travel in economy and the worst experience I ever had ! Shame on paying 600 dollars to be in a tuna can ! Service was terrible no even water no even class no even matters your flight attendants were lazy and sloppy very bad experience! After all these years traveling in first and once I try this cause I need to go to a destination for an emergency wow shame on you !

1st flight had mechanical issues after we boarded and almost took off. They tried to fix on runway but couldn’t do we went back to the gate. They couldn’t fix it there either. So we had to deplane and board another plane 2 hrs later. All in all our flight was delayed 4 hrs so we had to cancel some business meeting we had in London for the morning since we were supposed to arrive at 7am and did not arrive until 11:45am. Also, the 2nd plane had mechanical issues as well but fortunately they were able to fix on runway.

The captain was amazing and kept us informed throughout that there would be some rough air. The flight also got delayed but we were able to actually leave on time, which was great.

Flight boarded and didn’t take off on time. No worjing entertainment or power socket one side of the plane.

It got me where I needed it to; not much more. It had no competition so that was why I chose it.

Plane didn’t even make it off the ground. We all had to get off and walk to a different terminal (lots of confusion) to get on a different plane. Landed fairly late, connections missed.

Crowded flight, but upbeat and kind crew. Pilot greeted us at door, flight attendant thanked a number of “special” passengers for their business, another addressed an eight-year old boy as “young man.” United obviously trying to up their game, but though all of that is nice and notable, flying still feels like moving along a human assembly line, being herded into one small space after another (boarding areas with too few seats, planes with limited personal space, shuttles (IAD) packed too full.

It was ok until we got to DC and I wanted to use my United Club pass and the snobbish receptionist said that they don’t take one pass. It took me everything itch of patience not to tell her off

Food choice was poor and we had to buy on board snacks.

We were offer chocolate cookies , not everyone eat chocolate. Thank you

Lost luggage again. Our second trip to Mykonos, and 2nd time no luggage.

Flight was well orchestrated, made up time despite circling a bit all good on United. Travelers can just be so into themselves that common courtesy has gone out window for some, but that’s not on United.

Loading was quick and efficient. The bate and switch with discount tickets were you are forced to pay for bag.

Good flight, comfortable seats and very quick passage through Heathrow. Boarding in Washington was cramped and not well organized, but the rest was perfect.
