Flight was delayed at airport with large backlog and WiFi was spotty

Flight was delayed from San Diego due to being overweight for weather conditions. We missed our connecting flight to our final destination due to the delay, as well as the connecting flight leaving before the scheduled departure time. We missed the connection within 10 - 15 minutes. We were booked on a later flight arriving 7 hours later. There were 7 passengers sharing the same originating and connecting flight.

Horrible, mismanaged ground issue resulting in a long delayed, next flight left early, waiting extra 7 hours in the airport, screen did not work

The internet on these planes stinks. Need to get starlink

Very good flight. Crew was great. No issues and we even arrived early.

Loved the crew! Sucks that we went from 1 hour and 8 minute layover to a 3 hour layover. But weather sucks like that.

Delayed flight (1hour) plus a long layover after an overnight flight with no backup plane available.

Crew was excellent. Comfort seats not as nice as other kinds of planes.

Most aspects were good however if they assign boarding zones they ought to enforce them or why bother? My luggage from SAN-JFK-MAD was lost in NY so I without my main bag for two days upon arrival in Spain. They were helpful in tracking it and eventually delivered it to my hotel. The flub was because of a delay upon arrival in NYC. I had booked 2 1/2 hours between flights but we had to hold on the taxiway for an hour after landing while waiting for a clear gate which likely caused the baggage error.

Delta flight was great from the check in all the way to arrival. However, I had a very bad experience. I requested a wheelchair and the wheelchair employee that went to pick me up from the plane in Boston to bring me to the baggage claims told me I have to pay him. I was under the impression that it was a free service and I usually give tips but the person forced me to pay and since I said no because I was upset with his demand when my daughter walked in to pick me up he demanded payment from my daughter who paid him thinking maybe now it is a charged service.

Flight was on time, clean, etc. Despite connecting to your wi fi I was unable to use your app to watch entertainment.

The back to back mechanical delays from Denver to San Diego and then on my return flight from Denver to Great Falls it added extra time both ways

Service was professional and quick. Premium economy seat was comfortable given the class

The staff was extremely helpful and friendly at all times! They went above and beyond to get us into an earlier flight in San Diego to make our connection in SFO possible, because our original flight did actually not make it! I did so much appreciate the UA team and how they made this possible. We also didn’t have seats together on the long flight to Singapore, but they found us seats together last moment with no additional cost! Nobody sat next to us, so that we were able to sleep! Thanks to UA for improving their service and Underpricer for booking this trip! Please be careful: 1,5 hrs for transfer in San Francisco might not be enough time in the future

Over 2.5 hour maintenance delay on first morning flight with no acknowledgement, compensation or even gesture of good will. Aircraft had overnighted at airport so issue should have been addressed prior to boarding. Over 3.5 hours before first slow and deliberate beverage service.

Complimentary light meal would be appreciated. But great flight crew service on all legs

The food was terrible this time. Otherwise pleasant, quiet, on-time.

I was in first class. The outlets at my seat did not work. The plane was shabby and run down. I had prepurchsed a day subscription for internet that was not redeemable. I had to repurchase the internet for my flight and then it didn’t work anyway. Quite disappointed in what was supposed to be the launch of a great vacation.

As usual, United scheduling is completely misleading. A 54-minute layover at O’Hare is too short to make a lot of connections, especially since the flight landed “on time” but had to wait on the taxiway 15 minutes for a gate to open up. Then it takes another 10 minutes to exit the plane before one can run to another concourse to catch a connecting flight.

Flight was ok. Unfortunately it was a Boeing 737, which is a cramped / tight airplane. I prefer the Airbus as they are a more comfortable flight experience.
