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

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.

The food for long haul was poor compared to Singapore airlines economy. Pasta plain with tomato sauce . Singapore airlines give me Hagen dash small ice cream cup it was great. The choices of dinner course Singapore air also much better The crew mostly friendly. The economy seat are as expected.

Was 4 1/2 hours delayed. No food options, poor entertainment and cramped seats made worse by people in front reclining while we could not as in back row.

Ok, but comfort was lacking as the seats were way to small

The stewardess was excellent. Very accommodating in a quiet way, which was appreciated. The only thing that could have been better was the choice of snacks. Chips, cookies, etc. weren't an ideal way to start my day on a 7:00 a.m. flight. Offering fresh fruit, yogurt, or other breakfast foods would be great. 😁
