Airlines cancel over 7,000 flights so far

The latest data from FlightAware.com shows that US carriers cancelled 2,866 flights yesterday (Monday) in preparation for the storm.  For today (Tuesday), airlines have cancelled 4,615 flights, about 15% of all daily airlines flights in the United States.  Virtually all flights to/from New York (LGA/EWR/JFK), Philadelphia, and Boston are cancelled today. Although snow on the ground in New York City was not as significant as forecast, the mass transit needs to become operating so that airport and airline employees can get to the airport, then airlines need to resume flights to the affected airports before they can begin departures from
