More than 1,500 flights have been cancelled across the US on Monday and the cancellations are expected to continue due to bad weather.
A total of 4,800 flights have been cancelled across the country since Saturday with at least 15 states put under a wind chill advisory with warnings of sub-zero temperatures.
Heavy snowfall in places such as Dallas and Atlanta forced airlines to cancel more than 1,630 flights and delay another 3,850 flights, reported USA Today.
The Dallas/Fort Worth International Airport (DFW) was the worst hit with maximum disruptions. The airport cancelled 1,100 flights.
The airport said in a statement on Monday: "The airlines today have been utilising DFW Airport's aircraft deicing facilities for departing flights, and this is expected to continue through tomorrow morning.
"In all, the airlines proactively cancelled more than half of all flights scheduled from DFW Airport today in anticipation of the predicted ice and sleet. That amounted to more than 550 departing flights and almost as many arrivals."
An American Airlines plane taxiing to Terminal C at the DFW slid off the taxiway and got stuck in the grass due to the heavy snowfall.
All 63 passengers and five crew members onboard the flight from San Antonio were deplaned safely.
The airport's airfield operations crew has been working since then to keep runways open and clear the taxiways of ice.
