The Federal Aviation Administration (FAA) issued ground stops at 10 U.S. airports across the Northeast on September 3, 2026, halting all departures amid severe thunderstorms. These stops affected major hubs including LaGuardia Airport, Newark Airport, and John F. Kennedy International Airport (JFK), as storm activity disrupted air travel for a third consecutive day.
Delays Across Major Northeast Airports
During the thunderstorms on September 3, LaGuardia Airport reported average ground delays of 45 minutes while Newark Airport experienced peak delays averaging two hours. Boston Logan International Airport led the nation with 19 flight delays linked to the severe weather. The ongoing storm system had caused disruptions
on September 1 and 2 as well, marking a rare multi-day weather event impacting air traffic.
Geographic Scope and Impact on Air Traffic Network
Thunderstorms affected airports across the tri-state area, extending beyond New York to Boston, Philadelphia, and Washington. The FAA implemented ground-delay programs at Newark, JFK, and LaGuardia to manage arrivals amid the storm. The persistent thunderstorm coverage in the Northeast and Mid-Atlantic regions created restrictions that cascaded through the national air traffic network, leading to widespread cancellations and delays.
Traveler Impact and Airline Response
Passengers at LaGuardia and other Northeast airports faced flight restrictions and delays due to the ground stops. Airlines responded by issuing travel waivers, allowing customers to
rebook affected flights without penalty. These waivers apply to changes made as a result of the weather-related disruptions experienced on September 3.
Context of Unusual Multi-Day Storm Disruptions
The multi-day thunderstorm event spanning September 1 through 3 is unusual for the region. Severe thunderstorms have increasingly disrupted East Coast aviation during summer and early fall months. This event follows Tropical Storm Edouard’s landfall in Louisiana in late August, a precursor to intensified weather activity. Occurring during the Labor Day weekend, the weather disruptions compounded travel challenges amid high passenger volumes. Ground stops at multiple hubs caused cascading operational delays as crews and aircraft were unable to
reach scheduled destinations timely.
