Delta Air Lines cancels hundreds of flights due to winter storm Lines cancels hundreds of flights due to winter storm

The Atlanta-based airline said a wintry mix was to blame for lengthy delays on de-icing planes. By Friday evening, the carrier had canceled 625 flights from Atlanta.

The early winter storm is expected to move northward along the eastern seaboard leaving a trail of snow and slush along major airline routes, including the New York area and Boston.

Even relatively small storms can pose a big headache for airlines, which can end up with millions of dollars of lost revenue from costly cancellations and delays.

Delta, United Airlines and American Airlines have issued change fee waivers for customers flying out of potentially affected airports.
