What city is represented by the airport code SAN?

The airport code SAN represents San Diego, California. Each airport in the United States is assigned a three-letter code by the Federal Aviation Administration (FAA) that often reflects the name of the city it serves. In this case, SAN is derived from the initials of San Diego, making it the correct identifier for that city's airport.

San Antonio, Texas, while also starting with 'San', is identified by the airport code SAT, showing the distinction between cities with similar names. Similarly, Rochester, New York, and Roanoke, Virginia, have their own unique airport codes – ROC and ROA, respectively – which do not correspond to SAN. This identification system helps travelers easily recognize and distinguish between airports across the country.
