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. The FAA said in March that it would impose new safety restrictions at SFO that would end up limiting certain landings and lead to some delays.
The FAA says that a ground stop is declared when aircraft that meet a specific criteria need to remain on the ground. “The criteria may be airport specific, airspace specific, or equipment specific; for example, all departures to San Francisco, or all departures entering Yorktown sector, or all Category I and II aircraft going to Charlotte. GSs normally occur with little or no warning. Since GSs are one of the most restrictive methods of traffic management, alternative initiatives must be explored and implemented if appropriate,” it explains.
