Yet another flight in which beverage and snack service was skipped. Other that that, firmly mediocre. Landed early, to gate late due to congestion at the gates. Airline's fault or airports fault: unknown.

Yet another flight in which beverage and snack service was skipped. Other that that, firmly mediocre. Landed early, to gate late due to congestion at the gates. Airline's fault or airports fault: unknown.

Both flights delayed. 2nd flight over 3 hours late mechanical issues

Flight was delayed 45 minutes because originating flight was coming from Newark. No complimentary snacks were offered on this 5+ hour flight. No screens for the flight, but movies offered if you had already downloaded the United app (which I hadn't on my ipad). No USB ports, only a flimsy plug-in port near the bottom of the seat that was hard to see and kept coming unplugged.

It was good but only meal served is very less. Meantime good to add rice and chicken in one of meal

Teeny tiny bathrooms, crew was not realistic about when we'd arrive.

On the way my flight entertainment wouldn’t work the screen went black and no matter how many times I tried to turn it on it wouldn’t. Food was surprisingly good but the tray tables were tiny so you couldn’t get anything else on the table. The seats hardly go back and are not overly comfortable. Wouldn’t fly United again.

Unbelievably poor service from flight attendants. They didn’t even do water service on a four hour flight. Just disrespectful.

Flight was late - I was downgraded from first class to coach

Movie selection is good. Crew did not understand mileage program and were no help. Sick later. Food?

United needs to step up their game. Delayed flight leaving Seattle, San Francisco. Older aircraft, not very comfortable.
