Sfo Airport: What Does The Abbreviation Stand For?

San Francisco International Airport, also known as SFO, is the primary international airport for the San Francisco Bay Area in California. It is owned and operated by the City and County of San Francisco and is located 12-14 miles southeast of the city. SFO is the largest airport in the Bay Area and the second busiest in California. The airport's IATA code, SFO, is derived from the three-letter code distinctions established by the International Air Transport Association (IATA) in 1945. Prior to IATA, most airports were identified by the two letters used by the National Weather Service codes. As aviation advanced and more airports were established, IATA required airports to adopt three-letter codes, increasing the possible combinations from 650 to 15,600. SFO is a convenient abbreviation for San Francisco, with the 'O' likely added due to the city name ending with an 'O'.

SFO stands for San Francisco International Airport

The airport's history dates back to 1927 when the City and County of San Francisco leased 150 acres of land for a temporary and experimental airport project. The airport, then known as Mills Field Municipal Airport of San Francisco, was officially dedicated on May 7, 1927. The land was leased from the Mills Estate, with an agreement made with Ogden L. Mills, who oversaw the large tracts of property originally acquired by his grandfather, the banker Darius O. Mills. In 1930, San Francisco purchased the property and the surrounding area, expanding the site to 1,112 acres. The airport's name was officially changed to San Francisco Airport in 1931, with "International" added at the end of World War II as overseas service rapidly expanded.

Today, San Francisco International Airport (SFO) is the largest airport in the Bay Area and the second busiest in California, following Los Angeles International Airport (LAX). In 2023, it ranked as the 14th busiest airport in the United States and the 29th busiest in the world by passenger traffic. SFO serves as a hub for United Airlines and Alaska Airlines and is known for its extensive art program, with permanent and temporary exhibitions throughout the terminals.

The airport code SFO was established by the International Air Transport Association (IATA), which was formed in 1945. Before IATA, most airports were identified by two-letter codes used by the National Weather Service. As aviation advanced and more airports were established, the two-letter codes were no longer sufficient, and IATA required airports to adopt three-letter codes, increasing the possible combinations from 650 to 15,600. For San Francisco International Airport, the addition of the letter "O" to the city's initials, "SF," resulted in the unique airport code of SFO.
