About 1,000 US flights canceled as winter weather snarls travel

Nearly 1,000 Monday flights have been canceled in the US as winter weather moves through the middle of the country.

Most of the cancellations so far are affecting Dallas Love Field and Dallas-Fort Worth International airports in Texas.

As of about 4:30 p.m. ET, about 990 flights within, into or out of the US had been canceled Monday, according to flight tracking site FlightAware, with more than 3,600 delays.

About half of those cancellations are Southwest Airlines flights. The Dallas-based airline, which had an operations meltdown over the holidays, had canceled about 12% of its Monday schedule – about 480 flights, according to FlightAware.
