Loved the easy process to board and the experience overall was smooth

Set on the plane for two hours before pushing off the gate due to the power source issue being fixed which was known before letting people board the plane. On top of that it was very hot as AC was not working properly. Terrible experience and limited communication provided by the crew on the status of the issue. They should let people deplane while issue is addressed instead of frying them and glued to the seats.

I am United’s newest fan. The planes are clean, the staff is so friendly and snacks are more than just old pretzel crumbles. The captain came and said hello! Truly amazing experience

1 person checking us as we boarded, left gate on time, 12.30 we are told we were held for 15 mins as other flights were waiting to take off, captain due to rain … they were having a longer gap between take offs , 3pm we took off , they went land route via New Orleans in to Florida landed at 5.45pm offered coffee and a biscuit

Service was slow Flight was very loud at back of plane

There was no internet on the flight. As an executive flying during prime business hours, having internet is critical for a smooth experience. This impacted productivity and time that will need to be spent later to do the work I could have done on flight.

Terrible boarding - 4 flights boarded from the same gate. Chaos there; long ramps to the plane.

Fine except from Chicago to moline three different gate changes and flight times

Why wasn't this flight departure scheduled eith another crew so that it could leave on time? When we arrived in Denver we had so little time between flights we had run to the connecting flight. We should received some credit for the inconvenience.

My flight was 3 hours late, which caused me to miss my connection in Denver. Further, this connecting flight was then Later canceled. This required me to stay another night an hour and a half away, and rent the rental car for an additional Night. I am still waiting for United Airlines to reimburse me for the inconvenience and Expense of having to extend my rental Car for An additional Day.
