They did the one thing that really matters - got to Chicago early.

I liked the snacks and the flight attendants were friendly.

The flight was delayed for 1:30 hours for maintenance issues. They should give more information about connecting flights. For a Business Cabin the Crew was mediocre.

Very turbulent trip made it pretty bearable, plus the lack of refreshments served and the lack of any air conditioning before takeoff which took an hour or more.

Flight was late - I was downgraded from first class to coach

Not good - outbound flight was delayed and missed my connection even though I got to the gate after running through the airport - the agent would not let me on because the door was closed (flight had not left). There was no notification from United - overall experience was very disappointing. Additionally, I was downgraded from first class to coach on the alternative flight

The flight was on time. I generally don’t drink or eat on short flights and the seats were good and the flight attendants were friendly. That’s all I expect

Movie selection is good. Crew did not understand mileage program and were no help. Sick later. Food?

Staff on board was excellent. Positive upbeat helpful- like it used to be.

It was nice to have gotten up upgraded to first class with a meal on a three hour flight
