Air travel in the Northeast expected to face continued cancelations, delays into Wednesday

Lingering snow and subfreezing temperatures mean that travel delays in the Northeast will extend through Wednesday, even if the storm wasn't as bad as expected.

Airlines have already cancelled more than 500 flights for Wednesday, according to FlightAware.com. But that's a reprieve after more than 7,500 U.S. flights got scrubbed and another 3,100 ran late on Monday and Tuesday, mostly in the blizzard's path.

New York was spared the worst of the blizzard, but Boston was hit with more than two feet of snow. By Tuesday afternoon, airlines had already canceled one-fourth of the flights that would normally depart from Boston's Logan Airport on Wednesday, and subfreezing temperatures will mean tedious de-icing of the planes that do take off.
