The Charleston County Aviation Authority (CCAA) owns and operates the Charleston International Airport (CHS), Charleston Executive Airport (JZI) on Johns Island and the Mount Pleasant Regional Airport (LRO). Chartered in 1970 by the State of South Carolina as a special purpose district, it is responsible for managing, operating and developing all public airports in the Charleston County Airport District. The Aviation Authority coordinates its activities with the Federal Aviation Administration and the South Carolina Aeronautics Commission. The Aviation Authority District is governed by a 11-member board. The South Carolina House and Senate delegations representing Charleston County each nominate three members (approved by the governor) and one member is jointly appointed by the Charleston County Council and the Charleston City Council. The mayors of the City of Charleston, City of North Charleston and Town of Mount Pleasant, the chairman of Charleston County Council and the chairman and vice chairman of the Charleston County Legislative Delegation serve as ex-officio board members. The appointed members serve four-year terms.
