  • FAA

    Ground delay program

    The FAA is metering arrivals into SFO by assigning inbound flights a departure delay before they leave. That assigned delay is not the same thing as how late flights end up running.

  • Ground stop or delay program possible after 7 PM PT

    FAA's own wording, from the Operations Plan advisory issued 4:35 PM PT.

What this means

The FAA is metering arrivals rather than stopping them, so flights are moving, just slower than scheduled.

Individual flights can still be delayed or cancelled when the airport looks fine. Check your airline for your actual flight.

Usually at this time

77%

of SFO departures left on time on a typical Monday, across 21,961 flights. Monday evening is one of SFO's rougher stretches historically.

Historical departure punctuality from U.S. Bureau of Transportation Statistics, June 2025 – May 2026. This is a separate measurement from anything above: the FAA's delay figures describe traffic-management actions taken today, and averaging the two together would produce a number that means nothing. A ground stop is still a ground stop on an airport's best weekday.

Flying out soon?
