Missed connection flight because denver air connections plane was delayed a broke

The crew handed out candy snacks, and water, which was great. However, the airport and airline are terrible at flying. Multiple delays on our departure flight and on return flight it was delayed so long that we missed the connection flight and had to drive home. Terrible service and did not get any compensation. All of their equipment was broken and they never tested it before the plane landed. We were stuck in Ironwood Michigan for five hours.

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

Sitting on the runway after we land for almost two hours! Not sure if we should blame United or Just Dumpy Vance.

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

Crew seemed a bit cranky. No seatback screens. But boarding was efficient and on time and we arrived early.

See previous note about the passenger in Denver who threw my husband's bag out of the overhead bin in order to maker room for his own. And the flight attendant back up the new passenger.

Terrible. They wouldn't allow me on my flight on the 14th..

Impressed with the service despite turbulence because of the weather. Both flights arrived before their scheduled times.

Great experience…left a bit behind schedule but made up fir that in the air and landed 10 minutes early 😁

Electric plugs didn't work. Entertainment system wasn't working

The design of the light switch on the arm rest is ridiculous.

The gate attendant let me walk right by her with a bag too big for the overhead compartment
