The seats on this flight weren’t as comfortable as we had expected. Even leaned back these seats left us feeling crappy in our backs. Also we had to use our own tablets for movies, but nothing in the seats in front of us to hold the tablets up.

The seats on this flight weren’t as comfortable as we had expected. Even leaned back these seats left us feeling crappy in our backs. Also we had to use our own tablets for movies, but nothing in the seats in front of us to hold the tablets up.

I was fully checked in the prior night and i was unchecked and then didn’t have a seat when I boarded. Instead of an aisle seat, I was out in the middle seat of the very last row of the plane.

Having a long layover, I was very appreciative of the ability to stand by for an earlier flight. Other airlines like Delta have refused this to me in the past, just to be mean (because my ticket class wasn't high enough). United went out of their way to help me get to my destination early, which I really appreciated given that it was the third leg of a 24+ hour journey for me.

Survey sent before we actually left. Delay after delay. Now a crew problem.

Not really their fault, but a 4.5 hour delay is pretty brutal

we were delayed going into and out of Newark Airport by 3-4 hours each way. Excuses/reasons given were misleading. Weather was cited at first when there was NO weather issue. Turns out Newark had a shortage of staff and runway construction. United knew this and should have NOT scheduled flights when they know we would be delayed so long. I will avoid United and EWR airport at all cost going forward. Delta never looked so good.

Late out of the gate, late to takeoff. No screens on plane. Uncomfortable window seat.

The staff was very friendly. The seats seemed quite small. Overall the flight was pleasant.

Crew did their best but the plane configuration is too tight if you're bigger than an average sardine. Controls for the entertainment system didn't all work. The aircraft hadn't been cleaned in awhile.

Going through customs and having a connecting flight is impossible in Chicago.
