More than 7,000 flights were disrupted across the eastern United States on Tuesday, July 21, 2026, with over 2,000 flights canceled and more than 5,000 delayed. Airports servicing the New York City metropolitan area, Boston Logan International Airport (BOS), Philadelphia International Airport (PHL), and Washington, D.C., including Ronald Reagan Washington National Airport (DCA) and Washington Dulles International Airport (IAD), saw significant operational impacts throughout the day.
Severe Weather Conditions Including Tornadoes and Flood Warnings
The disruptions followed severe thunderstorms sweeping the region, accompanied by flood warnings and tornado watches affecting parts of the Northeast. Two tornadoes were confirmed—one in northeast Pennsylvania and another in northern New Jersey—contributing to
the hazardous weather environment that affected air traffic and airport operations.
FAA Ground Stops and Airport Impact
In response to unsafe weather conditions, the Federal Aviation Administration (FAA) implemented ground stops at multiple airports, including Baltimore/Washington International Airport (BWI) in Maryland, Boston Logan International Airport (BOS), 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), Ronald Reagan Washington National Airport (DCA), and Washington Dulles International Airport (IAD). Toronto Pearson International Airport (YYZ) in Canada also received a ground stop.
John F. Kennedy International Airport (JFK) was not under
a ground stop but experienced an average ground delay of approximately four hours as reported by FlightAware. The New York City metropolitan area reported nearly 600 departing flight cancellations and over 500 delays related to the storms.
Airline Responses to Disruptions
JetBlue has provided assistance to travelers impacted by consecutive rounds of severe weather, allowing rebooking of affected flights through Sunday, July 26, 2026, or refunds to the original form of payment. United Airlines announced a waiver of trip change fees for eligible customers who reschedule flights departing by Thursday, July 23, 2026, offering rebooking within the same cabin and routes without fare difference
fees.
American Airlines is notifying affected passengers through email and its mobile app, requiring rebooking by Wednesday, July 23, 2026, with new travel permitted through Friday, July 24, 2026. These flexible travel arrangements are aimed at mitigating the disruption caused by the storms across the region.
Traveler Impact and Ongoing Disruption
The combination of FAA ground stops, flight cancellations, and delays has disrupted travel plans for thousands of passengers. Airports serving some of the country’s busiest hubs encountered substantial operational challenges. FlightAware indicated that the number of affected flights could rise as storms continue moving through the Northeast region. Airlines remain engaged in assisting customers
with itinerary changes amid ongoing severe weather conditions.
