Old 757 with poor entertainment system. United no longer partners with United for free text and email. O'Hara an absolute disaster! Limited gates clauses two hour delay. Unfortunately this appears to be the norm.

Old 757 with poor entertainment system. United no longer partners with United for free text and email. O'Hara an absolute disaster! Limited gates clauses two hour delay. Unfortunately this appears to be the norm.

It was a good experience, unfortunately my checked baggages were come late and not arrived on time.

Very stressful to locate United Airline boarding area, delayed flight, changing boarding area again to another location with all tiredness 😩. But flying was fine.

It was hot and not as comfortable as the flight to Chicago. Must have been a different plane that needs to be worked on or replaced.

The SFO lounge closes at 12 midnight. My flight took off at 2AM

It was extremely hot in the cabin the entire flight, vent air was worn

Have not had a flight out or returning to Norfolk that has not required maintenance, and a gate delay. Properly staff the crew so maintenance can be performed without last minute emergencies on each flight and there is enough staff to have gates prepared for inbound flights. Staff to ensure the safety and on time service vs. profit.

My original flight was cancelled and that affected my trip and my plans and I got no compensation and customer service was hard to reach as well

The flight was delayed by a hour and I wish they had communicated it sooner. No issues on the plane, it did take a while for food to come.

Delays took 2hours and thirty minutes making me miss my connecting flight and make me sit in the Chicago airport for 9 hours

gate crew was courteous and helpful, flight attendant was nice and friendly once we got going. But we pushed off from the gate relatively on time, then sat there like 10 ft away, for an hour, with no announcement or explanation. Taxiing then took forever, and I get that there was runway congestion, but would be helpful to keep us posted on whats going on

The power outlets were not working for my row. Also felt like the seats have gotten smaller. I was in the window seat and felt like suffocated, as the two passengers next to me were tall and wide.

Terrible. The flight I booked had a convenient departure time. Quick layover. And an arrival timed that worked for the people who had to pick me up. Thanks to delays and rebooking I got none of those things

I had my flight of Cedar Rapids. THen Chicago to Boston. Flight out of Cedar rapids was delayed by 12 hrs. Had to drive to Chicago to catch my flight

Long delays to board due to mechanical issues with plane.

Flight was delayed, boarded, sat at the gate for more than 30 minutes, left the gate then waited on the pad for another 30 to 60 minutes then returned to the gate, deboarded and was cancelled... alternative flight was not booked automatically. Waited in line for 30 minutes but fortunately an alternate flight to a different destination was found ... no thanks to the travel agent used by kayak

The flight from Milwaukee to Dallas was great the staff absolutely amazing. After that EVERYTHING WENT DOWN HILL!!! ABSOLUTELY HORRIBLE!!! WILL NOT FLY THIS AIRLINE AGAIN

I was very unhappy with the lack of communication from the cockpit. It took close to a half an hour before we took off after the doors were closed, and we got no announcements as to progress. It would be nice to get some acknowledgement of the situation and updates as to when we are taking off.

We were upgraded to First Class and it was a great flight

We loved the steward on the plane. He made the night enjoyable
