Widespread storm creates single worst travel day of winter

Airlines on target for record setting day

Yet another storm swept across a large swath of the United States on Thursday, dumping heavy, wet snow that crippled travel options for millions of people. More than 6,500 flights had been canceled by midafternoon, making it the worst single travel day this winter, according to data from masFlight.

This current storm has so far caused more than 11,600 cancellations, compared with 9,700 during last week's weather incident from Feb. 2 through 6, said masFlight, a data company specializing in airline operations.

"I think this has a bigger effect because it's up and down the coast," said Michael Benjamin, CEO of FlightView, a flight tracking site.

By 3 p.m. EST, more than 6,500 flights were canceled and an additional 4,600 were delayed. Airports in Washington, D.C., Philadelphia, Atlanta, North Carolina, New York, Virginia, and Boston were among the locations with the most cancellations, according to FlightAware, a tracking service.
