Airlines have canceled more than 1,000 combined flights scheduled for Saturday at DFW International Airport and Dallas Love Field ahead of a winter storm that is set to sweep through North Texas this weekend.

A massive winter storm stretching 2,300 miles across the United States has paralyzed air travel, forcing the closure of nearly two dozen airports and triggering a ground stop at one of the nation’s busiest hubs.

More than 10,000 flights canceled as bitter cold blankets the U.S. As a dangerously cold weather front plunges into the U.S., tens of millions across much of the country can expect heavy snow, sleet and freezing rain.
