the seat has a problem. the back had a hole.

The back to back mechanical delays from Denver to San Diego and then on my return flight from Denver to Great Falls it added extra time both ways

Really old place. Not as clean as it should be, tray tables needed better cleaning. The items, trays and some other items need to b6 engineered. Anything task you or crew may do is incredibly load, seriously engineer for quiet smooth, easy. Just opening and closing the tray table is actually dangerous and can easily injure a finger. I'm sure it happens as it happened to me! First time I used United and likely will be the last!

Like the fact that the boarding was expedited. But the delay and chaos around the onboarding was not appreciated.

Flight was 2.5 late. Maybe not United’s fault but late none the less. We were late as well on the first leg. WiFi quit working with an hour left.

Old 757 with poor entertainment system. United no longer partners with United for free text and email. O'Hara an absolute disaster! Limited gates clauses two hour delay. Unfortunately this appears to be the norm.

The flight to America was freezing. The overnight flight back to the UK was boiling hot and the cabin stank of toilet or occasionally perfume, even though I was several rows back from either bathroom. Food was tiny portions. Two small pieces of tough and dry beef in random gravy with pretend mashed potato raking up most of it. Very little veg. Salad was ok. Wooden cutlery broke within minutes of using. Lots of old films for entertainment. Some new ones. Generally a bit rubbish.

It was a good experience, unfortunately my checked baggages were come late and not arrived on time.

Very stressful to locate United Airline boarding area, delayed flight, changing boarding area again to another location with all tiredness 😩. But flying was fine.

Flight staff and all was fine. Food always sucks on planes so nothing new.
