The Denver International Airport (DIA) had to cancel flights yesterday due to blizzard conditions. It was just too difficult to keep runways and taxiways clear, so United canceled about 200 of its 400 flights departures and arrivals, and Frontier canceled 19 of its 155 departures. Passengers on flights that had been delayed find themselves waiting one to four hours.
As of yesterday afternoon, about a foot of snow had dropped since Tuesday evening. But the wind — with 20 to 40 mph gusts — is actually the greater threat, rather than the snow.
The two east-west runways have been closed, but the other four north-south runways remain open.
Anybody with a flight scheduled into or out of DIA should check their flight status before going to the airport.
