(NECN: Alison King, Boston, Mass.) - Many airlines say rebooking flights could drag into Friday, in the wake of a powerful East Coast blizzard.
The major storm has left many people stranded at airports -- without a way to get home after the holidays.
Delta Air Lines says it canceled 700 flights for Monday. The world's second-largest airline company hopes to resume normal operations by early Tuesday.
Once flights resume normally, passengers could have a hard time finding open seats on later flights.
