Severe thunderstorms on July 23, 2026, disrupted more than 7,000 flights across the eastern United States, with over 2,000 cancellations and upwards of 5,000 delays, according to FlightAware. The storms affected flights operating within, into, and out of the region, causing operational setbacks in key metropolitan areas including New York City, Boston, Philadelphia, and Washington, D.C.
FAA Imposes Ground Stops at Major Airports
The Federal Aviation Administration (FAA) issued ground stops at multiple airports to manage aircraft movements amid hazardous weather conditions. Airports impacted by these ground stops included Baltimore/Washington International Airport (BWI), Boston Logan International Airport (BOS), Newark Liberty International Airport (EWR), Teterboro Airport (TEB), LaGuardia
Airport (LGA), Westchester County Airport (HPN), Philadelphia International Airport (PHL), Ronald Reagan Washington National Airport (DCA), Washington Dulles International Airport (IAD), and Toronto Pearson International Airport (YYZ) in Canada. John F. Kennedy International Airport (JFK) was not placed under a ground stop but experienced an average ground delay around four hours. In the New York City metropolitan area, close to 600 departing flights were cancelled and over 500 delayed.
Severe Weather Conditions Include Tornadoes and Flood Warnings
Flood warnings and tornado watches were issued across parts of the Northeast due to the severe thunderstorms. At least two tornadoes were confirmed: one in northeast Pennsylvania and another in northern
New Jersey. These extreme weather events contributed to the extensive travel disruptions reported across the affected regions.
Airlines Implement Flexible Policies for Affected Customers
JetBlue offered affected customers the option to rebook travel through Sunday or request refunds. United Airlines waived trip change fees and fare differences for eligible flights departing by July 23, 2026, allowing customers to reschedule without penalty provided the new itinerary matched the same cabin and cities as originally booked. American Airlines notified impacted customers via email and mobile app, requiring rebooking by July 22 with travel completed by July 24.
Continued Disruptions and Passenger Impact
FlightAware predicted that flight disruptions could increase as the storms moved across
the region. The combination of FAA ground stops, cancellations, and significant delays presented challenges for thousands of passengers attempting to adjust travel plans on short notice. Airlines continued to provide updates and assistance to passengers navigating the operational challenges caused by the weather.
