THOUSANDS OF FLIGHTS CANCELED, DELAYED ACROSS US DUE TO WINTER WEATHER
United canceled 310 flights and another 392 were delayed as of 11 a.m. ET.
The snow, ice and freezing temperatures rolling across the Northeast, Midwest and mid-Atlantic have been creating a headache for travelers as the conditions led to thousands of flights being scrapped over the holiday weekend.
Southwest told FOX Business that it "continues to notify customers of adjustments to our published schedule."
"We are seeing challenges ranging from wintry precipitation and blizzards to frozen equipment and other airfield constraints beyond our control," the carrier said in a statement. "The persistent dangerous sub-zero windchill requires rotating ground crews to limit their exposure."
On Monday, total delays across the country reached 10,919, while cancellations racked up to 3,342, according to FlightAware data. Those figures were slightly higher than Sunday when total delays reached 8,898 and cancellations rose to nearly 1,600.
The inclement weather isn't expected to stop either, though conditions are expected to change throughout the week.
