What city is represented by the code SFO?

The city represented by the code SFO is San Francisco, California. Airport codes, known as IATA codes, are typically three-letter designations used to identify specific airports around the world. SFO is derived from the first letters of San Francisco's name, making it an easily recognizable indicator of the city and its airport (San Francisco International Airport).

In contrast, the other options refer to different cities that have their own unique codes. Los Angeles, for example, is designated by LAX, while Boise is abbreviated as BOI, and Juneau's code is JNU. This distinction is crucial for travelers when booking flights or navigating airport logistics, as every airport has its own distinct code that reflects its geographic location.
