The media has been so focused on Metro NYC and Boston that I do not believe they realize the full magnitude of the situation.
UPDATE: Fifteen minutes ago from the New York Times:
Steven Gomez of Garfield, N.J., had been at the airport since 4 p.m. on Sunday for a flight to Chicago. “Now they’re telling me my flight is on the 30th,” he said. The trouble for airlines lies in finding new flights for delayed passengers. Airlines were running at record levels of capacity even before Sunday’s storm blanketed the city with 20 inches of snow during one of the busiest travel periods of the year. Through the first nine months of the year, domestic flights were fuller than at any similar period since the Department of Transportation began tracking.
With airlines flying fights so full, finding available space on new flights into and out of New York’s airports for nearly two day’s worth of passengers could take the better part of the next week.
“Flights are going out at a much slower pace than normal and there are crew availability issues as well,” said Allison Steinberg, a spokeswoman for JetBlue Airways. “Our goal is to resume as normal as possible by tomorrow. We’re doing all that we can.”
At this moment, average delays at Newark are 5+ hours and JFK 4+ hours. American Eagle's flights at LaGuardia cannot get to their gates and they have temporarily stopped takeoffs to LGA.
If you are stuck at one of the NYC airports, my suggestion: Take Amtrak home or go south on Amtrak or bus to Baltimore or D.C. where the snow is cleared and flights are operating more or less normally if the airline can give you a confirmed (in writing!) reservation and allows you plenty of time to get south.
