Passengers leaving SFO, July 2026
2.44 million passengers boarded flights out of SFO in July 2026, down 2.6% from a year earlier. 633,730 of them were on international flights, down 13.8%. Over the last twelve months departures averaged 2.21 million a month, against 2.35 million at the record, in the year to August 2018.
These are departures only, from the airlines’ own monthly reports to the federal government. The San Francisco International Airport’s headline passenger count adds arrivals, so it runs about twice these figures. A traveller connecting through SFO counts on the flight they leave on. Summer is the peak and winter the low every year, so compare a month with the same month a year earlier. The figures arrive about three months after the month they count.
