In anticipation of a strong winter storm heading toward the Northeast, airlines have canceled more than 2,000 flights for Friday, mostly from New York, Boston and Chicago airports.

The 2,004 cancellations for Friday are in addition to 475 flights canceled for Thursday and 454 canceled for Saturday, according to the flight-monitoring site FlightAware.

The National Weather Service has issued storm warnings and predicted blizzard conditions when two weather systems meet over the next 24 hours to "produce a major and potentially historic winter storm for the Northeastern U.S."

Because the storm is to cut through in the nation's busiest air space, airline passengers across the country will also feel some of the pain.

At Los Angeles International Airport, airlines have canceled 48 arriving and departing flights scheduled for Friday, according to FlightAware.

Many of the nation's largest airlines have announced they will waive the fees they normally charge to rebook a flight with a non-refundable ticket.
