Winter storm Fern unleashes historic chaos in U.S. flights

27-01-2026

The powerful winter storm known as Fern has battered large parts of the United States in recent days with extraordinary intensity, triggering one of the most disruptive weather events for air transport in recent years and having a profound impact on the daily lives of millions of people. The system, which has stretched from the South to the Northeast, has left behind a trail of mass flight cancellations, power outages, multiple fatalities, and extreme weather conditions that have prompted the mobilization of federal and state authorities.

From last Saturday and Sunday onward, the storm led to the cancellation of thousands of domestic and international flights at major U.S. airports, reaching totals that exceeded 10,000 cancellations in a single day—one of the highest volumes since the COVID-19 pandemic—with projections pushing the figure to more than 19,000 over the weekend as a whole. Key airports such as LaGuardia, JFK, and Newark in the New York area, Charlotte Douglas in North Carolina, and Dallas–Fort Worth in Texas experienced massive disruptions, with some operating at only a fraction of normal capacity due to heavy snow, ice on runways, and reduced visibility.
