​JFK and LaGuardia: FAA thunderstorm stops hit Delta’s New York hubs as flood risk rises

On Friday 6 November 2026, the FAA posted thunderstorm ground stops and ground delay programs across the New York metro and Northeast corridor. John F. Kennedy (JFK) and LaGuardia (LGA) — Delta Air Lines’ two main New York passenger hubs — sat under active weather initiatives, with Newark (EWR) and Boston Logan (BOS) in the same storm band. The FAA Daily Air Traffic Report flagged thunderstorms and low clouds for BOS, JFK, LGA, EWR, Philadelphia (PHL) and the Washington area. Local coverage also warned of heavy rain and possible flooding in parts of New York. This is a new weather wave — not the 13 September JFK/LGA thunderstorm stops already covered.

What travellers saw

NAS Status showed rolling ground stops into the early afternoon at LGA and BOS (and earlier windows at JFK and EWR), then ground delay programs with average assigned arrival delays on the order of tens of minutes at LGA and well over an hour at EWR in midday snapshots, plus lengthy departure delays from weather metering and SWAP. FlightAware snapshots cited by TheTravel put delay counts in the high hundreds across JFK and LGA while cells moved through; Delta was among the carriers with dozens of delayed flights at each field. Check your carrier before leaving for the terminal: a short stop window does not clear residual bank delays.

If the schedule is critical

When JFK and LaGuardia are both held for storms, Northeast connections stack fast. If you cannot absorb another weather hold, a private jet or empty leg into another regional field may be workable once the cells clear. Rahizi qualifies the brief and returns partner options.
