Airlines care continuing to cancel flights in the Northeast as Hurricane Sandy moves up the coast.
The massive storm threatens to bring a near halt to air travel for at least two days in a key region for both domestic and international flights.
Major carriers such as American Airlines, JetBlue and Delta plan to cancel all flights into and out of three area airports in New York, the nation's busiest airspace. Delays are rippling across the U.S. and the Atlantic, affecting travelers in cities such as San Francisco, Chicago and Paris.
Cancellations are mounting. According to the flight-tracking service FlightAware, more than 6,800 flights had been canceled so far. Both Philadelphia International Airport and Newark International Airport, a hub for United Airlines, each had more than 1,200 cancelations for tonight and tomorrow.
The Port Authority of New York and New Jersey, which runs five airports in the area, says it expects all carriers to cease operations tonight. It advised passengers to check with their carriers before heading to the airport.
Passengers today were reporting multi-hour wait times at airline call centers.
