2 runways closed at Denver International Airport; Frontier, United cancel some flights

Frontier, United cancel flights due to snow

DENVER — The snow storm moving across Colorado is causing headaches for airport travelers.

Frontier Airlines said they canceled 19 flights in and out of Denver International Airport on Thursday because the airport has been unable to keep enough runways and taxiways open. The airline also said some flights have delayed by as much as four hours.

United Airlines, the dominant carrier at DIA, canceled about half of its flights. Spokesman Charlie Hobart said the move keeps delays and cancelations from spilling over into the next day.

Airport spokesman Chuck Cannon says DIA crews are keeping up with snow removal.

Two east-west runways are closed and the remaining four are open.
