The Federal Aviation Administration (FAA) issued a ground stop at six major airports in the Northeastern United States, including LaGuardia Airport, on September 5, 2026, due to severe thunderstorms impacting the region. This measure halted all departing flights from the affected airports.
Thousands of holiday flights were disrupted by the FAA action, with American Airlines experiencing the largest number of cancellations and delays among carriers operating in the Northeast. The suspension affected air travel across the six airports throughout the day.
