Airlines across the United States have canceled more than 1,500 flights scheduled on Dec. 26 and 27 because of winter storm Devin, which is set to cover the Northeast with bad weather.

As of writing, 1,508 flights arriving or departing from a destination in the Northeastern United States were canceled, which affects subsequent flights scheduled to use the same aircraft in different destinations. New York City’s three major airports were the top three in the country for canceled flights by origin and destination.

At John F. Kennedy International Airport, the worst affected nationwide, 34 percent of all inbound flights were canceled, and 23 percent of outbound flights were canceled, according to the website FlightAware.

At LaGuardia Airport, 35 percent of all inbound flights and 20 percent of all outbound flights were canceled.

At Newark Liberty International Airport in Newark, New Jersey—which serves the New York metropolitan area—25 percent of all inbound flights and 18 percent of all outbound flights were canceled.

The Federal Aviation Administration’s website indicated that a ground stop was possible at John F. Kennedy and LaGuardia airports until 9 p.m.

Across the United States, more than 6,000 flights were delayed. The aiport with the most delays, 307 at the time of writing, was Chicago O'Hare International Airport.

Most of the airports affected are in the Northeast of the country. Philadelphia International Airport, the Detroit Metropolitan Wayne County Airport, and Baltimore/Washington International Thurgood Marshall Airport have faced significant delays and cancellations. Lester B. Pearson International Airport in Toronto, Canada—which is tracked within the U.S. National Airspace System—is also highly ranked on those lists, with an average delay of nearly three hours.

Most of these disruptions to flights are attributable to winter storm Devin, which is set to hit the East Coast on Dec. 26.

“An impactful winter storm is ongoing for the Northeast this afternoon and will continue overnight,” wrote the National Weather Service in a news bulletin about the storm.

“Cold air damming is providing the right ingredients for observed freezing rain across the northern Mid-Atlantic, while areas from northern Pennsylvania to southern Connecticut will see heavy snowfall. Difficult travel conditions are ongoing for the area.”
