10.0 Wonderful
The power at the seat didn't work and the seat itself was difficult to adjust - this was a business class seat. Flight attendant gave me miles to compensate. The attendant was very professional and on top of his game the entire flight.
V
4.0 Mediocre
Terrible. Our first time back on United for 10 years, the seats in Polaris class are small and uncomfortable. They have squished too many people in to get more $$$. The staff are not friendly and not wanting to accommodate. I asked for two salads rather than a main meal and was advised no we wont do that. Then asked what I would like for breakfast and given something else anyway. I will not be flying United International anytime soon.
C
4.0 Mediocre
Airport experience at Newark was not great. Only one gate open at immigration for US passports when multiple international flights arriving at the same time. Then having to take a train and a bus to different terminal only to have to clear security again, after I had already gone through at my initial departure location. Older plane, no entertainment screens available, and for economy plus, seat was very uncomfortable. Crew was friendly and this leg of my flight was on-time, even though I arrived later than initially scheduled due to 1st flight being over 2 hours delayed and missing my original connection.

2.0 Poor
Same thing as flight from Pheonix to Newark. Uograded and Promised extra leg room and when I got to the seat it had none.
P
6.0 Okay
I upgraded my seat and was promised it would be next to the emergency door for extra leg room and they said it was premium plus but it was at the back of the plane...same thing happened from Newark to Dubai

10.0 Wonderful
Just magically good
A
2.0 Poor
Bad food, bad service, cold cabin with no additional blankets when asked for (they told me they don’t provide additional blankets). I’m a frequent traveler and this is one of the worst companies I traveled with (by the way I thought that I booked my ticket with Lufthansa but I didn’t see that the flights were handled by United).
