The Federal Aviation Administration (FAA) implemented ground stops at nine Northeast U.S. airports on Thursday, August 6, 2026, due to severe weather conditions expected to include thunderstorms and damaging wind gusts in the region.
Flight Cancellations Concentrated at LaGuardia and Newark
Flight disruptions began Wednesday, August 5, and continued into Thursday. LaGuardia Airport recorded the highest cancellations worldwide on Wednesday with 37 departures and 27 arrivals canceled. As of early Thursday morning, LaGuardia had 43 cancellations, the most across all U.S. airports. Newark Liberty International Airport ranked second among U.S. airports with 27 cancellations on Wednesday.
Delta Air Lines Offers Waivers and Rebooking Options
Delta Air Lines issued warnings for nine Northeast hubs, including LaGuardia
and Newark, in response to the disruptions. The airline is waiving change fees for customers rebooking flights scheduled for August 6 and 7, 2026, if ticket changes are made by August 10, 2026. Rebookings must maintain the same cabin of service and destination to qualify for the fare difference waiver. Delta specified that fare differences may apply if the original booking class is not preserved in rebooking.
Traveler Delays and Operational Challenges at LaGuardia
Delta customers experienced lengthy delays at LaGuardia Airport, with some flights delayed over two hours due to air traffic control issues. A Delta passenger noted a delay on a typical Indianapolis (IND) to
LaGuardia (LGA) flight of more than two hours attributed to air traffic. Additionally, staffing shortages affected Delta flight DL2396 (LGA to Palm Beach International Airport, PBI) caused by the availability of only one pilot, further delaying the flight.
Causes: Severe Weather, Air Traffic Control Constraints, Staffing Shortfalls
The FAA cited the forecast for thunderstorms and potentially damaging winds in the Northeast throughout Thursday afternoon and evening as the primary cause for the ground stops. These weather conditions have exacerbated existing air traffic control delays at LaGuardia. Pilot shortages and other staffing challenges have compounded delays for specific flights.
Official Statements and Expert Commentary
Delta Airlines confirmed that the waiver applies to tickets changed on
or before August 10, 2026, in the same cabin and destination as originally booked. Aviation expert JonNYC observed that airlines, including Delta, are preparing for major air traffic delays in New York City on Thursday due to weather. He noted, “Delta: a NYC cancel package is in the works for tomorrow. The company is expecting weather conditions to drive significant ATC delays in NYC Thursday.”
Widespread Disruptions Expected to Continue
The FAA ground stops and severe weather are driving ongoing operational challenges across the Northeast, with major airlines like Delta Air Lines and JetBlue affected due to their high capacity in New York and Boston
hubs. Flight cancellations and delays are expected to increase as thunderstorms persist through the day, impacting passenger schedules and airport operations.
