Which city is represented by the airport code SFO?

The airport code SFO represents San Francisco, California. Each airport has a unique three-letter code assigned by the International Air Transport Association (IATA), and SFO is specifically designated for San Francisco International Airport. This code is based on the location's name, where "S" stands for San and "FO" stands for Francisco.

Understanding airport codes can help travelers easily identify airport locations and ensure smooth travel planning.
