Lufthansa was great from Lisbon to Frankfurt. The United Airlines flight from Frankfurt to Denver was very cramped. In that tight space, when the seat in front was fully declined I could barely move. I'm a fairly small person, I can't imagine what a larger person would feel like.

Lufthansa was great from Lisbon to Frankfurt. The United Airlines flight from Frankfurt to Denver was very cramped. In that tight space, when the seat in front was fully declined I could barely move. I'm a fairly small person, I can't imagine what a larger person would feel like.

There was no food available for this red eye... one little waffle cookie for a 6+ hour flight... thank God I was able to sleep some

This is for UA2274 from Houston to Sacramento. The flight was delayed arriving due to mechanical issues so we left about 3 hours later than scheduled. When boarding the plane the temperature inside was excessive - likely close to 100. Pilot apologized and said it was going to improve at altitude, which it did. But before that I honestly thought there might have been more delays removing passengers made ill from the heat. We were delayed leaving due to another mechanical issue. There was not water on the plane due to a panel that was not secured. They did that quickly, but the combination of mechanical issues was rather disturbing and did not reflect well on United.

I found the staff to not be very attentive at all. When paying for Business Class you expect a certain type of service and that was not found. They were almost rude even

Evidently, my seat had the only broken TV. I couldn’t plug it in, get it to come on, or watch anything, and of course, no one could fix it while we were on the plane. The service was good and the boarding was quick

The boarding of took of late.The presentation of the food was horrable as was the tast of the food was cold and tastless.

So far so good but food and entertainment are not available for this flight

Stewardess spilled orange juice on my clothes/seat no help no apology just threw napkins at me to clean the mess up. Not Happy.

Compared with other carriers business class for an overnight was not worth the extra expense.

Mostly the experience was good except for the flight changes made by UA which meant longer layover in DC
