Airport hub · SFO
San Francisco International climbed back to 54.1 million passengers in fiscal 2025 (+5.5%) — 54.53 million in calendar 2025, +4.3% — with international enplanements up 5.9% and nonstop service to 58 international and 86 domestic airports. Yet the airport remains roughly 5% below its 2019 peak of 57.5 million: the Bay Area’s business-travel base rebounded slower than the nation’s leisure-led recovery, and SFO’s recovery is a study in high-value traffic rather than volume.
SFO’s passenger mix explains the city’s tourism economics better than any hotel report. Domestic traffic (37.97 million in FY2025, 70.4%) is still rebuilding its business component; international (15.99 million) punches far above its share, with Asia and the Middle East at 12.7% of total traffic, Europe at 7.8% and the South Pacific at 1.8%. Top international gateways by seats: Taipei, London, Seoul, Vancouver and Hong Kong — a list that maps the Bay Area’s tech, finance and diaspora ties rather than its leisure demand.
The airport’s operational recovery runs ahead of its passenger one: 416,288 aircraft movements in calendar 2025 (+7.7%) on 7,226 weekly flights, with departing seats up 7.3% year-on-year while Oakland and San Jose shrank — SFO consolidated the Bay Area’s air capacity even as its total stayed below 2019.
The 5% gap to the 57.5 million peak is concentrated where the city lost office commuters and the Chinese outbound market, both of which carry low yields. Meanwhile the metrics that pay airport bills are at records: cargo tonnage +3.7%, international enplanements +5.9%, and monthly records through summer 2025 (July 5.28 million passengers, the busiest month in the airport’s history).
The TIO framing: SFO is a quality-recovery airport. Compare it with volume-first hubs and it lags; compare revenue per passenger and it leads. The strategic watchpoint for 2026 is the World Cup test: six matches at Levi’s Stadium in June–July put SFO in the unusual role of event-gateway for Santa Clara — the airport’s ability to process 300,000–500,000 match-day visitors is the dress rehearsal for the next transpacific growth cycle.
The TIO Read: SFO is the most misunderstood airport in the series. The headline — still below 2019 — sounds like underperformance; the composition says the opposite. International up 5.9%, cargo at records, a July 2025 all-time monthly high and a seat share consolidating from Oakland and San Jose. This is an airport repricing toward long-haul, high-yield traffic while shedding the low-value commuter volume the region has not fully restored. Watch two numbers: transpacific seat growth (Taipei, Seoul, Hong Kong tell the Asia story) and international share during the World Cup window. If both climb while the total stays near 54 million, SFO’s “shortfall” is the best kind — smaller, richer, and ready for the next cycle.
