(CNN) — More than 1,000 flights were canceled across the United States on Monday as wintry weather moves to the center of the country, with disruption expected to continue through Tuesday.
The most affected airports so far are Dallas Love Field, Dallas-Fort Worth International, Austin Bergstrom International and Houston Bush International in Texas.
Two other western airports, Harry Reid International in Las Vegas and Denver International in Colorado, are also experiencing significant delays.
As of 11 p.m. ET on Monday, just over 1,100 flights within, to or from the United States have been canceled, according to flight tracking site FlightAware, with more than 5,000 delays. More than 900 Tuesday flights have already been canceled.
Southwest Airlines did not immediately respond to a request for comment. As recently as Monday morning, CEO Bob Jordan was outlining fixes to prevent a repeat of the airline’s Christmas travel slump.
American Airlines and regional carrier SkyWest have also experienced numerous delays and cancellations.
Weather exemptions for travelers
Dallas Love Field tweeted Monday that its team “stands ready to treat and clean surfaces to enable safe operations.” DFW was also preparing for bad weather.
Both airports have urged travelers to check with their airlines for flight status before heading to the airport.
