What city is represented by the airport code SAL?

The airport code SAL corresponds to San Salvador, which is the capital city of El Salvador. Each airport code is uniquely assigned to help identify airports efficiently and reliably. The code SAL derives from the city's name, which includes "San" and a representation of "Salvador." This system helps distinguish airports across different countries and ensures clarity for travel planning and logistics.

In the context of other choices, while Santiago, San Jose, and San Antonio are also cities with respective airports, their codes are distinct: Santiago is represented by SCL, San Jose by SJO, and San Antonio by SAT. Understanding these codes is crucial for recognizing and navigating international flights and travel itineraries.
