The head rest is too big and cannot be placed differently/removed. Causes one head to tilt forward and increase back pain

The head rest is too big and cannot be placed differently/removed. Causes one head to tilt forward and increase back pain

We sat on the hot plane for ours with very conflicting messages. Some (most?) of this may be due to the flight control staff, but we were also repeatedly getting "we are leaving"/"we are not" messages. It was very uncomfortable

It was terribly delayed with zero support from united airlines. I reached at 1 am in the night. They did not provide any option to change the flights.

It was perfect! United Airlines staff was extremely caring, super friendly and professional

UA28 was good service and meals. UA is upgraded, I would like to book for next flight by UA Thanks Liao

Food is very bad and entertint not too many options ... flight attendet service is not good

For a 17 hour flight, they kept us well feed. The music selection could be better curated. The entertainment selection was about what is expected. The crew was fantastic.

The male air hostess was rude and didn’t provide good customer service. Didn’t even offer me a drink

I forgot to pre order gluten free on a 16 hour flight and I am pretty sure the crew raided their own lunches and first class to keep me fed.

This trip was a Christmas gift to our family. We were flying from Lexington to Palm Springs. When we were checking in the ticket agent said one bags was over weight by 4 LBS. We were flying first class which has baggage weight of 70 LBS per bag, one bag was 54LBS. We then had to take items from one bag to another. The agent also saw we had a dog with us. Once on the plane we were seated with the dog in the carrier. The United ticket agent came in the plane with two other people, I believe one was TSA and the other some security officer. The United agent said we had not paid for the dog ticket. We had paid for the ticket when we purchased our tickets. She did not give me time to find the email receipt. She then threatened all three of us with either I come with her or she would have all three of physically removed from the plane. I left the plane to pay for another ticket. She had to take my credit back to where we checked in. She acted as if it needed to be done immediately. She said we had 3 minutes. We then sat at the gate for approximately another 45 minutes. This was so embarrassing…to be threatened to be removed from a plane that we paid for all tickets including the dog. The flight attendance on the next leg of our trip were not very attentive to the passengers. On the plus side all the flights were on time. All in all, this was a miserable way to start a holiday vacation. United Airlines showed no compassion towards the whole incident. I feel we were purposely neglected.
