More than 7,000 flights in the United States experienced disruptions on July 23, 2026, due to severe thunderstorms, including over 2,000 cancellations and more than 5,000 delays, according to FlightAware data.
Major Airports in Northeastern U.S. and Canada Affected
The Federal Aviation Administration (FAA) imposed ground stops at several key airports in the eastern U.S. amid the severe weather. Airports impacted 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, and Ronald Reagan Washington
National Airport (DCA) and Washington Dulles International Airport (IAD) in Virginia. Toronto Pearson International Airport (YYZ) in Canada was also subject to a ground stop. John F. Kennedy International Airport (JFK) did not have a ground stop but experienced an average ground delay around four hours during the afternoon despite the absence of an official hold.
Airline Flexible Policies for Affected Passengers
JetBlue, United Airlines, and American Airlines offered flexible options for passengers affected by the weather disruptions. JetBlue allowed rebooking through Sunday, July 26, or full refunds to original payment methods. United Airlines waived trip change fees and fare differences for customers adjusting flights with
departure dates between July 20 and July 23, 2026, if traveling on equivalent itineraries with the same cabin class. American Airlines required affected customers to rebook by Wednesday, July 28, for travel scheduled on or before Friday, July 30, 2026, providing notifications through email and their mobile app.
Severe Weather Conditions Including Tornadoes in the Northeast
Extreme thunderstorms led to flood warnings and tornado watches across parts of the Northeast U.S. Two tornadoes were confirmed: one in northeast Pennsylvania and another in northern New Jersey. The FAA’s ground stops aimed to restrict aircraft movement temporarily to maintain safety amid these conditions.
Passenger Impact and Operational Challenges in New York City Area
The New York City metropolitan area recorded
approximately 600 canceled departing flights and over 500 delayed on July 23, causing significant passenger disruption. JFK Airport’s average ground delay reached about four hours, the highest in the region, despite no official FAA ground stop there. This situation reflected the broader operational challenges faced across multiple hubs, including Boston, Philadelphia, Washington, D.C., and Toronto.
FAA and Airlines Manage Ongoing Disruptions
The FAA implemented multiple ground stops on July 23, 2026, to mitigate safety risks caused by severe storms. FlightAware noted that flight disruptions continued as the storm system moved through the region. Airlines maintained active communication with travelers and continued accommodating changes to travel plans
because of cancellations and delays arising from weather conditions and air traffic restrictions.
