My youngest didn't have a assigned seat until we biard6the plane.

Booked a premium seats weeks ago and got an email the night before that id instead be seated in the cabin. Only reason I booked this overnight flight was for the better seating. All they are doing to compensate is giving a $29 coupon to use on another flight. I won’t be booking this airline again.

It was all great all around. Will travel with Alaska next trip.

I got the last seat on the plane, in the back in the corner against the window, and I paid a competitive price for my ticket several weeks before the flight.

Everything was good. However, the selections of movies and TV shows were boring and unexciting. It was disappointing.

Long delay before boarding. By the time I was informed of the delay I was already at the gate.

There was no seating at the gate, no where to charge your devices, super crowded. Boarding in group F meant all luggage space was taken when it was time for me to board. The boarding crew was short with everyone and seemed irritated. The luggage space was insufficient, the seat was too small for me (6'4") and very uncomfortable trip. I was in a middle seat between a person snoring the whole trip and a person with very strong body odor. The flight crew was terse and unfriendly, seemed irritated and impatient. Yelled a lot at people with earbuds in, understandable. Finally, we arrived 10 minutes early, only to sit on the tarmac for 20 minutes and wait for a gate. Worst flight experience I've had in years.

I made a mistake. Read what I wrote in the flight from Dulles to SEA. The negative experience was from SEA to BOI. Total garbage. Wont do it again.

Flight 351 SEA to BOI was terrible. We got to cruising altitude and I needed to use the restroom but the fasten seatbelt sign never came off. There was no turbulence and I'd felt the plane level off so I stood up to use the restroom about 15 minutes after we leveled off. The stewardess went over the intercom and said I needed to be seated because the captain hadn't turned off the fasten seatbelt sign....Which... Fair.... But not five minutes later she went and used the bathroom. Felt very unprofessional to leave a paying customer with a burning urethra for the entire flight and bark at them to sit down and still use the bathroom yourself. They never did turn off the seatbelt sign.

For longer trips, snacks are puny, boring and don’t have ANY nutritional value.

A bit rush for transit. Food and entertainment are not available

Smooth boarding process. Early departure, smooth flight, early arrival. The entertainment package has very good recent movie options. The flight crew were friendly and professional.

My flight was scheduled for about 6:05 departure. There were 11 gate changes from 4-7pm and the flight was 3 hours delayed due to operational issues. The plane taxied around the airport for about half an hour before stopping to be de-iced. It would have been nice if we were alerted of the plan to de-ice prior to the 30 minute drive around the airport. The flight attendant was friendly, which was the only redeeming thing about this flight. As a former flight attendant for United, I was extremely disappointed.

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

Had a short delay once we boarded the aircraft in Chicago, but it was fixed in no time flat then we were on our way. The pilot was able to make up the time lost and we landed 5 minute later then schedualed . Great service

Our seats were all the way in back of the plane,

The seats on this flight were almost roomy enough to be the basic amount needed for human existence. I think my favorite part of this flight was it landed at an A gate, which was the most palatial part of Sea-Tac I've ever seen - a massive improvement from the S gates.

The seats on this flight were almost roomy enough to be the basic amount needed for human existence.

The flight attendants in First Class were mediocre at best. They did not take our tray away until we were about to land and only did so when I press the call button. The United person at the United Club was asked to get us our boarding pass since we missed the flight due in Chicago. She argued that we did not have seats on the flight given to us in Moline. Furthermore, she was adamant that we did not have a First Class ticket. After I spent much time with her trying to show we were correct, she reluctantly agreed. She was probably the most incompetent ticketing person I have ever met and I have traveled 3 million miles on United plus many additional miles with other carriers. United has definitely deteriorated in more than on way.

Short flight - no food understandable. Flight was delayed for over an hour. Overall, it was good.
