San Francisco International Airport (SFO) is one of the busiest and most advanced airports in the United States, serving as a major gateway to Northern California and the Pacific region. It is the second busiest airport in California, playing a key role in both domestic and international travel, especially across Asia and Europe.
History and Origins
SFO opened in 1927 as Mills Field Municipal Airport and gradually expanded alongside the growth of commercial aviation in the United States. Its strategic location on the West Coast made it a natural hub for transpacific routes.
Over the decades, SFO has evolved into a modern, sustainable airport, with major renovations completed in recent years—particularly the transformation of Harvey Milk Terminal 1, now one of the most innovative terminals in the country.
SFO is widely recognized for its focus on passenger experience, including art exhibitions, wellness spaces, and eco-friendly design.
Terminal Overview
SFO consists of four passenger terminals arranged in a circular layout known as the “Terminal Loop”:
- International Terminal (Boarding Areas A & G)
- Terminal 1 – Harvey Milk Terminal (Boarding Areas B & C)
- Terminal 2 (Boarding Area D)
- Terminal 3 (Boarding Areas E & F)
The International Terminal is the largest in North America and handles most long-haul flights.
The airport layout is intuitive if you follow the loop, you can easily locate any terminal without confusion.
