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.

I paid $380 for my one-way ticket from California to Minnesota. The fair did not include online check-in. I received instructions from their app to check in at a kiosk. At the kiosk, the boarding pass would not print until an actual person came to verify that I had a personal item and not a carry-on item, On the plane, the person next to me was drunk and allowed to continue to order alcohol. United is garbage I’d rather fly spirit.

The plane was dirty and the in seat air wasn't blowing as planes usually do.

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.

All flights were on time and boarding was issue free

Terrible! The plane was old and you are required to connect your own device to their Wi-Fi rather than have entertainment options in the back of the seat in front of you. The Wi-Fi went out during the flight and there was only one plug for the devices every two seats. Three out of five surrounding my family did not work. The seats and spaces under them were so small I could not fit my backpack, which I’ve always brought on flights and fit before no problem. The crew were unpleasant and patronizing.

Great! The plane was decently sized and comfortable. The staff was nice and there was great in flight entertainment

Water service would be great. The way they board is terrible. Slow passengers first😂😂 They need to smart up a bit

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.

Crew were fine, drinks and snacks were as well but we were delayed for around 2 hrs which made our entry into Mexico delayed as well with the influx of arrivals at the same time. Sort of wasted our first day of vacation. We left Pittsburgh at 630am and did not arrive in Mexico until late dinner time.

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
