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

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
