The food not that great. Did not like the fact that we could not purchase upgrade at the airport

We paid for business class, and my seat did not work at all. Each time I wanted to adjust the position, an attendant had to come to physically force the seat into its new position. They tried to fix it by fiddling with the electronics (military reset, for example), to no avail. Also, the food was just mediocre. We were at the end of a serving section, so they ran out of several choices. (This was on the flight from Los Angeles to Munich.)

The crew was the best I’ve ever encountered. Business class was spacious, immaculate, and very modern.

The plane was very clean. The bathroom was clean as well. The land crew were very polite and informative and helpful. They informed me that there is a long way and challenging to go from international terminal to national terminal and in addition to getting my suitcases and going through customs and dropping them again for my second leg of trip which was San Francisco to Los Angeles . I have left knee issue and had a recent fall with aching muscles all over, the land crew suggested wheelchair help for me, God bless her. If I did not have help, I could not make it to my last terminal. Thank you UNITED AIRLINE!

I like the service and the efficiency. I am lactose intolerant and the lactose intolerant meal in business class was not astounding. Also, the business class fully reclining seats are not that comfortable.

Food was great but they didn't clear my meal tray for 3 hours. You'd think they could check though the cabin now and then.

Upon arriving at IAH, it was informed that the luggage had not arrived. Still waiting to hear back when it will be delivered.

I wasn’t allowed to board with my children. I was charged outrageous costs for basic carry on size luggage. The entertainment screens were outdated and not user friendly.

I was very happy with everything, thank you for the smooth flight ✈️

helpful and friendly. The Lufthanza people I dealt with before my holiday were so unhelpful by comparison.
