Flight was late. Club was full. Experience is exactly what I expected.

Flight was late. Club was full. Experience is exactly what I expected.

Inflight entertainment stopped working as we taxi to runway and never worked again until landing and taxi to gate. Grrrr

The seat could use more support or cushion. I'm in my 50's and have back issues so the seats are a bit hard for longer flights.

Delta flight overall it was goodT!the crew could do more and the food could be better.

This flight was supposed to land at 10:55 pm on January 14th. Instead, it landed at 3:20 am on Monday, January 15th, resulting in a completely lost day due to not going to bed until 5:00 am.

Airline stewardess service is good. The check-in attendant had a bad attitude and was unprofessional. We did not complete the trip as originally planned. Very dissatisfied☹️

Crew was wonderful, very professional and pleasant. On time performance. Excellent flights,smooth. Thank you!

Fast boarding and exit. Different snacks other than almonds and sun chips.

The flight was overbooked and the staff at the gate started calling for volunteers to drop out and offering incentives. That delayed the flight

Update the cabin with tv screens or at least music sources.

The flight and boarding were easy peasy. I was traveling with my 4-year-old, so a smooth boarding experience was especially appreciated. My only piece of feedback is really about where our gate was in O'Hare. They've shoved four gates into a tiny corner of the B terminal and there isn't early enough room or seating for everyone. Not United's problem, but did dent the overall experience.

Dinner was okay but the breakfast was not eatable on the flight San Francisco to Zurich.

There was no screens on board AND the WiFi didn’t work. My seat was broken and couldn’t recline so I couldn’t even sleep. The flight attendants didn’t offer anything to make it more comfortable. It was such an old cramped plane, when the person in front of me reclined I couldn’t even open my tray table. All the United ads talk about guaranteeing everyone gets a screen!

The Wi-Fi was unavailable on this flight for some reason.

On time take off…US cabins look tired and need of refresh!

Fantastic. Smooth boarding with an infant. Never experienced it with any other carriers.

This was a Lufthansa flight, not United. The CSA at the counter, Ashley, was not only incompetent, but quite rude. Me and two other PAX waited over 7 minutes standing in front of her and another CSA and they ignored us. We joked that we must have accidently taken invisibility pills. She could have at least said "I'll be with you in a moment, I'm currently....". I could go on about how rude she and the other CSAs were (whispering, not communicating with me, blaming the situation on others, etc.). She would not work for me. Then, she gave me literally the worst seat on the plane. the worst. My seat kept getting bumped (rammed twice by the crew with their carts and about every 5 minutes by someone using the bathroom), listening to the bathroom all night, crowded seat, etc.

My seat was broken. WiFi didn’t work. Gate crew at HOU were rude and condescending. Treated all the passengers badly. Bad experience, United.

First flight of the day… MINIMUM FUEL! 15 minute landing delay at HOU due to fog turned into a 2+ hour delay! Rather than circle, they had to divert to another city to refuel! Sat on tarmac at Austin to refuel. We ALL missed our connections! The crew, including pilots, were clueless. Crew was really a mess. At HOU, Untied employees were exceedingly rude to all. It was pitiful.

An hour and a half late is UNACCEPTABLE. The negative impact to our family is unconscionable. And for the price we were forced to pay...

I am upset with the hidden fees for bringing on an overhead carryon onto flight and also having to pay for my seat selection. This should all be part of the original price of the ticket. Very poor customer service

Well we did not realize at first it was a ground transfer, but we really enjoyed it and would definitely recommend to friends and family. Our driver was awesome and the ride was wonderful. A bathroom on board would have been nice, but at least we were warned that there wasn't one so we went ahead of time.

We were on a fairly long flight and they offered nothing for a snack (unless you paid) and then quickly gave you a drink and were never to be seen again. I would have loved a refill on my water but that was not an option. The flight attendants were standing on ther phone when we boarded and left and never even greeted us. Any other flight I have been on they would have welcomed us on the plane and again greeted us as we got off. Our landline transfer from MSP to Rochester on the other hand was FANTASTIC! We would highly recommend!

Took forever to get the plane loaded and unloaded. Longest I have ever had. I was in the middle of the plane and it almost took a hour after landing to get off of the plane.

Our flight was delayed and there was no communication at the airport.

Very hard to get comfortable in seat since they are too crowded. One of our suitcases was destroyed on the flight and is unusable now. No one at ticket counter when we arrived and no indication on when they would be in service. When we finally got into the airport past the TSA, all restaurants were closed.

Very hard to get comfortable in seat since they are too crowded. One of our suitcases was destroyed on the flight and is unusable now.

The plane boarded on time (at a gate next to Delta which was 2 hours late). No compatible headphones for me to purchase.

Crew was courteous. Flight was late arriving which made us late. Very cramped seating.

Flight attendants could have been more engaged in the passengers. They were more interested in talking to each other
