As Northern California’s most prominent and busiest airport, San Francisco International Airport (SFO) is a gateway from the Bay Area to the world. The airport is one of the few worldwide with two sets of parallel intersecting runways and boasts wonderful terminal and ramp views. Few other airports offer consistently visible parallel approaches and departures all day long – a fantastic perk for planespotters as San Francisco is one of the largest international gateways in the United States.
