Severe winter storms swept across large portions of the United States on Friday, severely disrupting peak holiday travel and prompting airlines to cancel more than 1,300 flights while delaying thousands more. Hazardous weather conditions affected key travel corridors from the Great Lakes to the Northeast, straining operations at some of the nation’s busiest airports.

According to flight-tracking website FlightAware, as of 2:15 p.m. ET a total of 1,382 flights had been canceled and 4,685 delayed nationwide. The disruptions came as millions of Americans attempted to travel during one of the busiest periods of the year, heightening congestion at major hubs and compounding passenger frustration.

The National Weather Service (NWS) issued winter storm warnings related to storm system Devin, cautioning that it would create dangerous travel conditions from the Great Lakes through the northern Mid-Atlantic and into southern New England through Saturday morning. Forecasts indicated significant snowfall, with 4 to 8 inches expected from upstate New York to the Tri-State area, including New York City and Long Island, late Friday into the night.

Major airports in the Northeast, including John F. Kennedy International Airport, Newark Liberty International Airport and LaGuardia Airport, warned travelers via social media of potential delays and cancellations. More than half of all flight disruptions nationwide were concentrated at these three airports, underscoring the storm’s impact on the New York metropolitan area.

Airlines moved quickly to adjust schedules and offer flexible rebooking options. JetBlue Airways led cancellations with 225 flights, followed by Delta Air Lines with 186, Republic Airways with 155, American Airlines with 96, and United Airlines with 82 cancellations. Airports in other affected regions, such as Detroit Metropolitan Wayne County Airport, also reported operational challenges as snow and ice conditions worsened.

Beyond the Northeast, the NWS also flagged additional weather threats, including a slight risk of flash flooding in southern California and strong winds and thunderstorms along parts of the West Coast, complicating travel nationwide.

With winter storm and ice warnings remaining in effect across the Northeast, airlines cautioned that further disruptions were possible through the weekend. Travelers were advised to monitor flight status closely, allow extra time for airport procedures, and take advantage of flexible change policies as severe winter weather continues to test the resilience of US holiday travel.
