A ground stop was in place for San Francisco International Airport in California, the U.S Federal Aviation Administration said in an advisory on Sunday, June 7.
The ground stop applied to flights involving some Western U.S. air traffic control centers, an FAA notice that listed the duration of the ground stop as 9:53 p.m. to 11:15 p.m. PDT (0435 to 0615 GMT on Monday) revealed.
However, it was lifted slightly before the end of that period.
The ground stop was declared when aircraft that meet a specific criteria need to remain on the ground. The FAA said it would impose new safety restrictions at SFO that would end up limiting certain landings and lead to some delays.
More than 54 million passengers traveled through SFO in 2025, its website says. Various airlines operate from the airport, which is a United Airlines hub and offers many international flights to and from Asia in particular.
