A powerful bomb cyclone all but shut down air travel in the Northeast late Sunday and early Monday, with thousands of flights canceled or delayed.
According to tracking website FlightAware, over 5,300 U.S. flights were canceled as of Monday morning, and over 800 were delayed. Almost all flights at New York-LaGuardia and Boston were called off, and JFK, Philadelphia, Newark, New Jersey, Hartford, Connecticut, and Providence, Rhode Island, saw over 80% of their daily schedules canceled. Also affected were Reagan National and Baltimore/Washington, though not quite as severely.
JetBlue, which has hubs at JFK and Boston, was hit harder than most U.S. carriers, with about 80% of all flights canceled, FlightAware data showed. United, Delta, and American hovered below 20%.
Arriving on Sunday, the storm has battered much of the Northeast with near hurricane-force winds and heavy snow. In some areas, over two feet of snow has fallen, and ground travel has been restricted in parts of New York, New Jersey, and New England due to near whiteout conditions.
Over 400,000 people in the region are reportedly without power.
As of Monday morning, the worst of the storm had moved to Rhode Island and parts of eastern Massachusetts, including Boston. About 40 million people remain under a blizzard warning.
