Airlines cancel hundreds of flights in Chicago

(AP) Hundreds of flights in Chicago have been canceled as a winter storm bears down on the Midwest.

Chicago aviation officials are reporting delays and more than 350 flight cancellations at O'Hare and Midway international airports.

Most of the weather-related slow-down Thursday was at O'Hare, where some delays stretched to more than two hours.

So far, the region is seeing high winds, rain and fog, which is reducing visibility.

Southwest Airlines has 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.

United Airlines and American Airlines are waiving fees for some travelers who want to change their plans.
