The Federal Aviation Administration (FAA) implemented ground stops at nine airports across the U.S. Northeast region on August 18, 2026, in response to severe weather conditions forecasted to include thunderstorms and damaging wind gusts. These measures aim to safeguard air traffic amid deteriorating weather during the afternoon and evening hours.
Delta Air Lines Issues Travel Warnings and Rebooking Policy
Delta Air Lines has issued travel warnings related to the FAA ground stops and announced a flexible rebooking policy. The airline is waiving change fees for passengers rebooking flights at nine Northeast hubs, including New York City-area airports. This policy applies to travel originally scheduled for August 6 and August
7, 2026, with rebooking permitted through August 10, 2026. Passengers must rebook in the same cabin and to the same destination to qualify for the waived fare difference unless travel classes differ.
Flight Cancellations Peak at LaGuardia and Newark Airports
Flight cancellations have notably impacted LaGuardia Airport, where 43 cancellations were recorded in the early morning hours of August 18, 2026—the highest of any U.S. airport during this period. On August 17, LaGuardia had 37 departures and 27 arrivals cancelled amid ongoing disruptions. Newark Liberty International Airport ranked second with 27 cancellations. These numbers are expected to rise as thunderstorms intensify across the New York metropolitan area.
Air Traffic Control Delays and Staffing Issues Affect Delta Operations
On
August 17, travelers at LaGuardia faced air traffic control delays unrelated to weather, with some experiencing nearly three-hour waits. One Delta flight, DL2396 from LaGuardia to Palm Beach International, was delayed due to a staffing shortage, operating with only one pilot on board. Passengers reported frustration with these delays on social media platforms, highlighting the operational challenges beyond weather disruptions.
Continued Disruptions Expected as Storms Move In
Thunderstorms moving into the Northeast on August 18, 2026, are forecast to increase cancellations and delays through the afternoon and evening, affecting New York and New Jersey airports as well as other major hubs in the region, including JetBlue-operated airports
like Boston. Airlines with substantial Northeast operations, including Delta and JetBlue, are anticipated to face ongoing service interruptions due to these conditions and resultant FAA ground stops.
Delta reiterated in its official rebooking policy that fare differences will be waived for qualified changes made on or before August 10, 2026, as part of its effort to mitigate customer inconvenience amid the disruptions. Aviation experts have confirmed that the FAA’s ground stops represent a safety response to severe weather, with prior ground stops earlier in the week impacting seven major airports.
