It was a red-eye, but the flight felt surprisingly quick. The seats were very comfortable, and that made resting much easier. I also want to thank the gentleman seated next to me, who graciously moved so my mom could sit beside me. We slept almost the entire way. The cabin crew was respectful in not disturbing us, while also being courteous and professional throughout. Thank you, United.

Packed in plane small uncomfortable seats elbow to elbow nobody wants to be in that situation for the money they paid

It was a more comfortable seat don't get stuck in middle, makes for uncomfortable situation

Business class would have been better , poor quality blanket , services

First time flying with UA and it was a great experience. Thank you

Overall flight was ok. Flight attendant was receptive to assisting passengers with tight connections.

Checking in united could not figure out my star alliance gold. Baggage did not get marked priority and didn't receive boarding passes. When got to SFO lounge personal fixed everything Immediately

Meals were poor and service rendered on return flight was mediocre as compared to the flight we took to Germany earlier where the attendants were more attentive, energetic, and mindful of passengers' needs. Thumbs up to crew of UA 58. Thumbs down to UA 59..

Very comfortable flight, snacks and drinks were good, good communication from crew. Could have used a little more information on timing of boarding for group 5

Great flight. Got to watch a movie. Smooth flight and early arrival at ORD.
