Travelers are suffering through another difficult day as winter's icy grip causes airlines to delay and cancel more flights.
By late afternoon Monday, nearly 1,200 flights in the U.S. had been canceled and 3,000 more had been delayed, according to tracking service FlightAware.com.
Nearly half of the canceled flights are at Chicago's two big airports, O'Hare and Midway, where the forecast calls for snow into Monday night.
Through last week, airlines have canceled more than 75,000 domestic flights since Dec. 1, the highest total since the U.S. Department of Transportation started keeping track in the winter of 1987-1988.
