It was great with the exception of a rude desk member on the way back. And a terrible sandwich on the way back.

One of the best flights Ive had in a long time

My tray was broken and instead of being moved I was provided blue tape.

One hour delay. No Wi-Fi. Old aircraft. Nasty food

Was unable to check in online within 24 hours of departure

Overall, good flight and quiet cabin! Took the red eye home from Honolulu to LAX!

Couldn’t check in online. Unsure of terminal. Missed flight by minutes due to confusion and not being able to check in online pre flight.

Grumpy and rude gate attendant who was unwilling to help anyone who asked him for assistance. Too little leg room.

The food was lame for an almost 5 hour flight, but overall I had a good experience

VERY short notice (<24 hours) flight delay by 6 hours. Had to reschedule and pay more to book with another airlines.

Check in etc was very good. As for on the plane, it was like flying in a freezer. It was so cold, i have flown for years and never been so cold on a plane. Staff on board said its always cold when flying which is a load of rubbish. They wouldnt put any heating on and now i have the flu because of this .

I’ve had a couple flights this week on United that were delayed by an hour or more

Should have video screens Plane audio was poor and without wired connection hard to understand crew. Should serve more than just cups of water and pretzels on six hour flight. Did not see crew rest of flight. Fix charging sockets to retain charging blocks.

My bag was lost with my medicine and I am very inconvenienced. I don’t know what happened, however I want you to do a better job on getting people’s bag back

Generally good but there wasn’t any staff available when my luggage didn’t appear at baggage claim in Fresno. It took about half an hour to locate a staff member to open up the locked room where it was being kept.

Do not like the feeling of being in the basic economy. Everyone should feel good no matter what.

Our original business class flight was cancelled so we not only downgraded but we were also spread out across the plane not sitting together in separate middle seats. My poor kids were scared and couldn’t see me on the flight and the crew wasn’t sensitive to the situation and what the airlines did to us. Very dissatisfied with United airlines.

The WiFi didn’t work and the seats are too close together. Very uncomfortable.

So so. Terrible aircraft choice for that leg of the flight.

Our seat tv didn’t work All the rest was perfect
