Close to 10,000 total flights have been canceled since the beginning of a holiday blizzard that blanketed much of the U.S. northeast with snow and left thousands stranded. Airline representatives from AirTran, American, Continental, Delta Air Lines, JetBlue, United, U.S. Airways, Spirit and Southwest reported a total of at least 9,726 trips were called off due to weather since Saturday. Of those, at least 1,335 flights were canceled on Tuesday as major airports across the region slowly got back to normal. "With all the cancellations and delays, it'll be two to three days before the airlines are at a regular schedule," said Thomas Bosco, general manager of New York's LaGuardia Airport.
