United Airlines canceled more than 2,000 flights and over 5,000 others were delayed across the United States on July 22, 2026. The Federal Aviation Administration imposed ground stops at eight US airports, including key hubs in the New York City metropolitan area, Boston, Philadelphia, and Washington, D.C. The disruptions also extended to Toronto Pearson International Airport in Canada. In total, close to 7,000 flights were affected nationwide during the day.
Weather Conditions Trigger Widespread Disruptions
Severe thunderstorms with flood warnings and tornado watches struck the Northeast region on July 22, 2026, causing the extensive delays and cancellations. At least two tornadoes were reported—one in northeast
Pennsylvania and another in northern New Jersey—prompting the FAA’s ground stop orders to manage air traffic safely. The severe weather conditions spread operational disruptions across multiple major airports rather than confining the impact to a single location.
New York City Area and Major Hubs See Significant Delays
Nearly 600 departing flights were canceled in the New York City metropolitan area alone. John F. Kennedy International Airport experienced an average ground delay of about four hours in the afternoon despite not being under a ground stop at that time. Unlike ground stops, which halt departures completely, ground delays add wait time for flights already in the queue, contributing to extended travel
disruption for passengers at JFK and surrounding airports.
Airports in Boston, Philadelphia, and Washington, D.C., were similarly affected by the FAA ground stops and resultant flight cancellations and delays. The authority’s interventions aimed to balance safety with the expected gradual, flight-by-flight recovery as the storm system moved through the Northeast corridor.
