Over 1,900 flights have been cancelled because of the winter storm affecting the New York and Washington metro regions, according to the FlightAware flight tracking application and service.
The airlines with the most cancellation so far are ExpressJet, JetBlue and the American Airlines products. La Guardia is the most affected airport with 38 percent of arriving flights cancelled.
These cancellations will cause other delays and cancellations at airports not affected by this weather due to airlines being unable to get airplanes to the originating airports for those flights.
Some airlines are allowing passengers to change flights even if their flights have not been cancelled yet. For example, US Airways is allowing passengers to push their flights back to the 22nd, 23rd, and 24th. Prior to the storm, they were allowing passengers to move their flights a day earlier.
Travelers with cancelled flights should check the airline's website to see all options available. JetBlue is allowing passengers with cancelled flights to opt for a refund instead of a rescheduled flight.
While it will be powerful enough to cause massive disruptions today, the storm should pass quickly according to the Weather Channel.
