Flight attendant in first class gave poor service (like he didn't want to be there) and food was awful. We sat waiting for gate upon arrival over 45 mins.

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

Terrible. Out flight was delayed for 21 (twenty one) hours. United is a joke.

I love United was disappointed we had a two hour delay, however the Pilot did say safety first.

Since when do I have to pay for my checked bag? I have a United Explorer mileage plus silver card and I was charged for my checked bags. This also is an international flight. So I would like an explanation to be clear before I choose an airline please?

Very good - being handicap it was very hard for me in a center aisle bulkhead seat that Zi was assigned think it was 29-G as I had a hard time opening the entertainment screen and tray table. 30-G would have maid it easier. I was assign 29-G as it was the only handicap seat without being charged even though I was handicap (disability)

Smooth flight. As always dinner could have been more generous. Breakfast was great.

AWFUL. I have had the experience of traveling with many airlines across the world, and hands down United Airlines is the worst. Not one flight was on time, and I don’t think I met one crew member or staff member who wasn’t rude.

The bag drop personal were not helpful. There was no food on the flight. Boeing aircraft, lousy as always. Everything else was fine.

After checking in online i called United to make sure I have special food ordered ( kosher option). Representative I spoke with on the phone with assured me that special meal was ordered. On the plane, during meal service I was informed that there is no note about it and no kosher meal was ordered for me. Flight attendant said she will check if maybe was a mix up and meal is somewhere. But never came back with any update. So entire flight with no food...
