At least eight planes were diverted from Denver to Colorado Springs on Friday because of weather, and some passengers were left sitting on the tarmac for hours.

One of those flights, from Kansas City, Missouri, kept passengers on the plane for more than six hours.

Passengers on Flight 4934, operated by Republic Airlines, asked to be let off the plane, but were kept on the tarmac. They were later taken by bus to Denver International Airport.

According to KOAA-TV, officials at the Colorado Springs Airport say they aren't sure why the airline didn't dock the planes at the gate to let the passengers off. It would have cost the airline $73.

Republic Airlines says the plane had to stay on the ground because of lightning and weather disruptions at DIA.
