CHICAGO (AP) - About 1,000 flights have been canceled as a winter storm bears down on the Midwest.
The bulk of the flights are at Chicago's O'Hare and Midway international airports.
American Airlines canceled all of its O'Hare flights scheduled after 8 p.m. Thursday, saying it expected winds to make it "very difficult, if not impossible, to operate" out of the airport.
Southwest Airlines canceled all its Midway flights after 4:30 p.m.
Forecasters say rain will turn to snow by Thursday evening. The Chicago area could get 2 to 6 inches of snow in the Chicago area, with wind gusts up to 60 mph.
Airlines are waiving fees for some travelers who want to change their plans.
