More than a thousand flights have already been cancelled in the Northeast in anticipation of a winter storm that is expected to dump at least a foot of snow across the region this week.
According to FlightAware’s cancellation listing for March 13, hundreds of flights leaving Chicago — where the same storm system already touched down Monday — have been cancelled. The listing for March 14 shows that hundreds more flights down the East Coast have also been axed, most of which are coming from airports in New Jersey, New York City, Boston and the Baltimore-Washington D.C. area.
Southwest Airlines cancelled 884 flights scheduled for Tuesday, while JetBlue has cancelled more than 600. Since making it in and out of the Northeast in the next few days may be problematic, here’s what you should do if your flight is cancelled.
