The FAA said planes headed for Los Angeles were held at their originating airports starting at 11:42 a.m. Eastern time, causing delays averaging an hour and 40 minutes. The agency said it expected to lift the ground stop at 1:30 p.m. Eastern time but might continue to restrict traffic into LAX.

Staffing shortages also caused takeoff and arrival disruptions Sunday at New Jersey's Newark Liberty International Airport and Teterboro Airport and at Southwest Florida International Airport in Fort Meyers, Florida, according to the FAA.
