The FAA says it's slowing flights into John F. Kennedy International Airport, LaGuardia Airport, Newark Liberty International Airport, and Philadelphia International Airport because of weather and staffing constraints at the air traffic control facility that handles flights at these airports.
Newark was under a ground stop due to thunderstorms.
Ground delays and stops are expected on and off throughout the evening at these airports.
A ground stop means some or all flights departing for that airport are held at their origin until the ground stop is lifted. A ground delay means flights can still depart for the specific airport, but they are delayed departing their origin and are issued a specific takeoff time to keep planes spaced out. It prevents traffic jams in the air and keeps planes from circling as they wait to land.
You can find the latest flight delays and cancellations on the Flight Aware website, and the latest FAA advisories and ground stops on their website.
