Charleston International Airport (CHS) serves Charleston, United States, and lies approximately 12 miles from the city center. The airport sits at an elevation of 46 feet above sea level, a low coastal setting typical of the region it serves.

The available route information for CHS points to domestic connectivity within the United States, linking Charleston with major hub cities served by large national carriers. This pattern suggests an airport oriented primarily toward serving domestic business and leisure travel, connecting the region to key metropolitan centers elsewhere in the country rather than functioning as an international gateway. Travelers using CHS should expect a network built around single-carrier domestic routes to significant U.S. hubs, supporting onward connections across the national air system. The low elevation and coastal proximity mean that weather patterns typical of the southeastern United States, including humidity and coastal weather systems, can be a relevant factor for those planning travel through this airport.
