Since its inception and until 1970 the airline had its headquarters, main hub and maintenance center at Los Cerrillos Airport (ICAO: SCTI; IATA: ULC), in South-West Santiago. The restrictions imposed by the growing metropolitan area of Santiago and the need for modern, jet-era airport facilities that could safely accommodate both domestic and intercontinental flights, drove the need to relocate the Chilean capital's principal airport from Los Cerrillos in the denser south-west metropolitan region of Santiago to the more rural northwest metropolitan area. For this reason, Santiago International Airport in Pudahuel was built between 1961 and 1967, fully moving LAN-Chile's flights to this new airport in 1970.
