SAN FRANCISCO INTERNATIONAL AIRPORT is one of the United States’ oldest and most established airports. Once a single dirt strip in a cow pasture, SFO has grown into a major international gateway and a leader in airport services. Operated by the City and County of San Francisco, the airport has expanded its facilities and amenities over the decades to offer travelers much more than simple transit: from lounges and food courts to art installations, museum exhibits and guided experiences, SFO is a destination in its own right.
In 2017, SFO handled 55,814,906 passengers, capturing nearly 70 percent of the Bay Area’s airport market share. Domestic travel made up more than three-quarters of that traffic. The airport serves 62 airlines, with United Airlines operating the largest presence. Among domestic routes, Los Angeles remains one of the most popular destinations served from San Francisco.
Arriving at SFO early gives you plenty of options to fill your time. The airport offers a wide range of activities and quiet spaces so travelers are rarely bored while waiting to board. Self-guided exhibits, dedicated children’s play areas and spots for relaxation help make layovers and early arrivals pleasant and productive.
The Aviation Museum and Library provides a compelling view into San Francisco’s aviation history. Housed in a faithful recreation of SFO’s 1930s-era lobby, the museum features rotating exhibitions, research resources and educational programs that highlight the airport’s past and the broader story of flight in the region. For travelers seeking a quieter experience, the Berman Reflection Room offers a calm environment for meditation and contemplation, while the Christian Science Reading Room provides a peaceful spot to read and unwind.
For those who prefer active relaxation, SFO includes two yoga rooms and four XpresSpa locations distributed throughout the terminals. These facilities give weary travelers opportunities to stretch, relax or get a massage before the next leg of their journey.
Traveling with children is made easier by several play areas designed specifically for young visitors. These spaces combine hands-on activities with opportunities to burn off energy; some focus on art and natural science themes to keep kids engaged and entertained before boarding.
SFO’s commitment to service extends beyond amenities and into community engagement. The airport regularly hosts events and workshops that support employees and their families. For example, a recent free citizens workshop provided screening for citizenship eligibility, legal consultations and other assistance to those pursuing naturalization—an example of how the airport supports its community in practical ways.
The airport also invests in operational improvements to keep pace with demand and enhance the traveler experience. In mid-November, SFO unveiled a new automated security-screening process developed in collaboration with the TSA and United Airlines. The upgraded lanes feature larger bins to accommodate bigger items, wider countertops that allow multiple bins to be scanned simultaneously, automated conveyor systems and improved line-tracking technology. Together, these enhancements aim to streamline security checks and improve efficiency across the terminals.
From its historic roots to ongoing modern upgrades, San Francisco International Airport continues to evolve as a full-service hub that balances efficient operations with amenities that make travel more comfortable and engaging. Whether you’re passing through on a quick connection or arriving early to explore, SFO’s mix of history, services and thoughtful facilities offers something for every traveler.
