Approximately 200 passengers evacuated the plane through emergency slides and some were seen running through the snow, away from the aircraft.

Atlanta-based Delta Air Lines canceled more than 370 flights Saturday, and long lines of travelers waiting to go through security stretched through Atlanta’s Hartsfield-Jackson International Airport’s domestic terminal and baggage claim areas.

Flight 2668 had 201 passengers onboard, who were evacuated from the plane via emergency slides and taken back to the terminal via ground transportation, according to officials.
