Denver air is great flight times and connections a little rough

Communication with delays. Failed to make a connection I ng flight in Chicago.

Excellent, from check Iin to arrival. I was apprehensive about flying a small plane between Ironwood and Chicago, but the flight and service was great. I noticed, after boarding , that my cell phone had little battery left. The flight attendant kindly lent me a charging device to keep me connected with my contact in Chicago upon landing. I will always remember that kindness.

Great snacks and friendly people for check in at Pierre SD!

The connecting flight came in 45 min late but everything else was great

Absolutely easy travels and no cost cutting by the airline.

Their snacks and hospitality was amazing. They offered full sized snacks. Im talking full sized water bottles, full sized snickers bars, gold fish, full sized canned sodas, what ever you wanted they took care of it for FREE. The crew was really nice and hospitable. I was honestly shocked

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

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

United have really come back. Airport and boarding process is clear and good, app and information also very good

Flight was delayed 8 times. We were sitting at the airport for 14 hours. We got 2 hours of sleep (if that) on what was not meant to be a red-eye.

After a delay at the gate, C3, at Ohare on Sunday, I left my Blk ski coat on the bench at the gate, lost! Please review my lob claim, thx.

Very bad! They kept delaying my flight and wouldn’t do anything about it

They brought an empty plane to the gate. Then a flight delay was announced for maintenance and waiting on a part. I was then put on a flight to San Francisco instead with a connecting flight to my final destination. Arrived at my final destination 2 hours late.

The only downside was my cell phone charger wouldn’t work in the charging port but everyone else’s would work in them all. My cell phone cable works fine in my hotel room in Frankfurt.

Flight team stood out for perzonal attention, kindness at bright cheery attitudes at 8am. Very helpful.

Ot was overall fine. Left on time and had basic snacks. Weather was finicky but that’s not the airlines fault.
