Freeze Cancels Thousands Of Flights

(Undated) -- Looks like air travelers can count on a lot of frustration today. The deep freeze that's locking down the Midwest and Deep South has resulted in thousands of flights being canceled. The flight tracking website says nearly 27-hundred flights have already been canceled today. Atlanta's Hartsfield-Jackson International Airport leads the way with over 400 flights wiped out. Houston's Bush International Airport is next with just over 300 flights cancelled. Regional carriers are most effected by the cold weather, with Delta and Express Jet both cancelling over 600 flights so far today.
