It is 4 nmi (7.4 km) east of the central business district of San Marcos, a city that is mostly in Hays County. The airport is owned by the City of San Marcos and operated by Texas Aviation Partners.[1] It is located east of the border of Caldwell County and Hays County.[2] Before it was operated as a civilian airport it was known as Gary Air Force Base.
