Flightstats.com has this breakdown of flight cancelations today caused by what the terrific flight-delay site unfortunatelty refers to as "winter storm Nemo," adopting the marketing stunt created by the Weather Channel to market snowstorms.
Alas, much of the media, especially the television ones, took the bait.
Anyway, flight schedules today are disrupted in the Northeast and, per usual, it will take many days for ther air travel system -- which is operating at virtual capacity routinely -- to sort itself out.
From Flightstats.com: "As of 4:00 AM EST, the storm has caused 2,074 flights to be cancelled for Saturday, February 9th at North American airports. Yesterday there were, 4,136 flights cancelled in North America.
