We arrived early and finally made it to our gate almost an hour after.

We were delayed 3x and because I didn’t purchase my tickets directly from United Airlines I was told I Have to take care of it myself so I called Underpricer and they helped me but before I changed my flights I took the risk of sticking by what my tickets were and was lucky to have gotten on the original all flight with only 15 mins before take off. not sure if I will do this again

The flight was delayed so the people from a late connecting flight was able to still make the connection.

Everything good until we waited for jet bridge at SFO. Then pilot gets on speaker & said it won’t reach plane- too short, need to go to different gate. Then 5 min later, adjusted plane/jetbridge & all ok?!?

Was a pain having to leave the plane and reboard but glad the plane was fixed

We had to wait almost an hour for the wheelchair porter to be ready to pick up my mother. And when she arrived in Newark airport the porter was not there and she started walking with her cane and her poor mobility. When the Newark porter found her they didn't want to transfer her bags to the wheelchair for her.

My experience was medium staff where great I dislike flying in triple 7 seats very uncomfortable and no room on jet all the rest of the flights where great

Great onboard crew. Boarding was a zoo, I got in line before pre boarding in Group 2, still had my bag force checked. WiFi was glitchy all flight. Seat and bathroom are both tiny unless you pay $$$ for first class.

Staff was generally seeming stressed out and was a bit rude and slow. Plane left late. Pilot was very well-spoken.

Cabin was pitch black, even during meal service. The reading lights for seat 2E/F did not work, and seat 2E did not recline.
