In 1997, AGUNSA, together with other international investors, created the private company SCL Terminal Aéreo Santiago S.A., in order to respond to the international call for bids made by the Ministry of Public Works of the Chilean Government.

At present, AGUNSA participates in the partnership with 47.02% of the ownership, which is aimed at expanding, operating and maintaining the International Terminal Arturo Merino Benítez.
