S.C. Code Ann. § 61-6-1555

Notwithstanding any other provision of law, an airline company may purchase beer, wine, and alcoholic liquor directly from a wholesaler licensed pursuant to the provisions of Section 61-4-520(3) or Section 61-6-100(2). A wholesaler may sell and deliver beer, wine, and alcoholic liquor to an airline company for use on the company's airplanes. A person other than an airline passenger who uses beer, wine, or alcoholic liquor purchased pursuant to the provisions of this section for another purpose other than the sale or use by the airline company on its airplanes is guilty of a misdemeanor and, upon conviction, must be fined not more than one thousand dollars or imprisoned not more than six months, or both. Each violation of this section constitutes a separate offense.
