It was good overall except from Omaha to Denver when flight a was a repeatedly delayed apparently due to some issue at Denver. Communications could have been handled better. I had to board then deboard with luggage and board again

It was good overall except from Omaha to Denver when flight a was a repeatedly delayed apparently due to some issue at Denver. Communications could have been handled better. I had to board then deboard with luggage and board again

Left an hour and a half after the listed time. Up side was it had TV screens on the seat.

No screens or meal options. Freezing cold. Dirty seats. Left late.

O’hsre taxi and deboarding took 40 minutes. Needed 20 minutes extra time between connecting flights to avoid running through terminal.

Seats very comfortable; service efficient and pleasant; flight was on-time; boarding organized.

Seats were not super comfortable and food was not good at all. If I had a chance I would definitely fly a different airline. Of course they are better than any budget airline, but not by much.

Overall a good experience, but no wifi available for free or for purchase and we got wet from condensation or other water source during descent.

Very friendly and helpful staff on board and United was excellent when I missed my onward flight due to the delay in London. Very well organised meant much less stress

Flew steerage class. Short on leg room unless you pay more. No window unless you pay more. Etc. United is trying to squeeze every cent from you. It doesn’t make for any loyalty.

Booked through Kayak Business, had a seat in middle and towards back due to booking rate, not comfortable.
