More than 1,000 flights have been canceled as a fierce winter storm makes its way from Minnesota to Virginia, threatening to dump as much as 10 inches of wind-whipped snow in time for the evening commute.
Chicago is supposed to be hit the hardest, not so much in inches of snow but in the number of affected people. O'Hare International Airport grounded around 900 flights, whereas Chicago's second airport Midway canceled 240. Another 100 flights were held in Minneapolis, Minn.
Even Washington, D.C., where the snow is still hours away, is suffering from the storm's impact -- more than 250 flights from Reagan National, Dulles International and Baltimore-Washington International airports Wednesday have been canceled.
New York, Philadelphia and Boston, where the blizzard is supposed to hit Thursday, are expected to start canceling flights in the next 24 hours.
Airlines started issuing winter travel waivers, in anticipation of weather-related problems. Policies vary from airline to airline, but they often waive change fees or fare differences. Jet Blue lets travelers rebook trips from Tuesday through Saturday, and United Airlines drops fare differences and change fees for travel rescheduled by March 11.
