More than 1,000 flights were canceled and hundreds of others were delayed across the United States on Monday as a winter storm brought heavy snow and ice to much of the country.
As of 6:45 a.m. ET, a total of 1,339 flights were canceled and 606 were delayed, according to aviation tracking website FlightAware.
Southwest Airlines canceled 265 flights, the most of any airline, followed by American Airlines with 176, according to the data. Washington, D.C.'s Reagan National Airport canceled 234 flights, the most of any airport, accounting for 58% of all flights scheduled there.
Major U.S. airlines, including Delta Air Lines, American Airlines, United Airlines and Southwest Airlines, issued travel advisories from Saturday to Monday.
Winter storm warnings and advisories were issued for more than a dozen states, from Kansas and Missouri to New Jersey, as the storm moved toward the Mid-Atlantic region on Monday.
“The snowiest areas in the region could experience the heaviest snow in at least a decade,” the National Weather Service said.
Washington, D.C. Mayor Muriel Bowser declared a snow emergency until at least the end of Tuesday, and Maryland Gov. Wes Moore also declared a state of emergency and warned residents to avoid travel.
