Nonrevs Beware...DEN.

A powerful blizzard swept through Colorado on Saturday, dumping at least 2 feet (61 cm) of snow in some parts of the state and forcing the cancellation of most of the scheduled flights at the Denver airport, officials said. United Airlines canceled all of its flights to and from Denver International Airport, the airport said in a statement. All told, more than 800 flights were grounded on Saturday, or more than 65 percent of all scheduled take-offs and landings at the airport, the FlightAware airline tracking website showed.
