More than 7,000 flights were disrupted across the eastern United States on July 24, 2026, as severe thunderstorms triggered extensive flight cancellations and delays. FlightAware reported over 2,000 flights canceled and more than 5,000 delayed across multiple airports in the region.
FAA Issues Ground Stops at Multiple Airports
The Federal Aviation Administration (FAA) imposed ground stops at several major airports to manage hazardous conditions caused by the storms. Airports affected by ground stops included Baltimore/Washington International Airport (BWI) in Maryland, Boston Logan International Airport (BOS) in Massachusetts, Newark Liberty International Airport (EWR) and Teterboro Airport (TEB) in New Jersey, LaGuardia Airport (LGA) and Westchester County Airport (HPN)
in New York, Philadelphia International Airport (PHL) in Pennsylvania, Ronald Reagan Washington National Airport (DCA) and Washington Dulles International Airport (IAD) in Virginia, as well as Toronto Pearson International Airport (YYZ) in Canada.
While John F. Kennedy International Airport (JFK) was not subject to a ground stop, it experienced significant operational slowdowns, with average ground delays of approximately four hours. The New York City metropolitan area saw nearly 600 departing flights canceled and over 500 delayed.
Severe Weather Conditions Across Northeast and Mid-Atlantic
The disruptions resulted from severe thunderstorms sweeping through the eastern United States. Weather warnings included flood warnings and tornado watches issued across parts of
the Northeast. Two tornadoes were observed during the storm: one in northeast Pennsylvania and another in northern New Jersey.
Airline Responses to Flight Disruptions
Airlines operating in the affected regions implemented measures to assist passengers impacted by cancellations and delays. JetBlue offered travel advisories and allowed customers with affected flights to rebook travel through Sunday or request refunds to their original forms of payment.
United Airlines waived trip change fees and fare differences for eligible customers rebooking flights departing between July 20 and July 23, 2026, provided travel was on United flights in the same cabin class and between the original cities. American Airlines communicated
with affected customers via email and its mobile app, requiring eligible travelers to rebook by Wednesday for travel scheduled by Friday.
Widespread Impact at Major Northeastern Airports
The combination of FAA ground stops, flight cancellations, and delays resulted in extensive operational challenges at some of the busiest airports in the eastern United States. Airports in New York City, Boston, Philadelphia, and Washington, D.C. experienced the largest scale of disruptions. FlightAware indicated the number of affected flights could increase as storms continued to move through the region.
Thousands of passengers faced adjustments to their travel plans amid ongoing weather hazards. Airlines continued to provide updates and flexible
options to travelers adjusting their itineraries due to the storm.
