Santiago's Arturo Merino Benítez International opened in 1967 in the Pudahuel district west of the capital, replacing the hemmed-in Los Cerrillos airfield as Chile's principal gateway. It carries the name of Comodoro Arturo Merino Benítez, the visionary founder of both the Chilean Air Force and the national airline that became LAN Chile. A dedicated international terminal opened in 1994 as Chile's export-driven economy took off. The airport grew alongside LAN's transformation from state carrier to privatized regional powerhouse.
Because Chile is a ribbon of a country walled off by the Andes, almost all of its long-haul traffic funnels through Santiago. The airport became the hub of LATAM Airlines after LAN's 2012 merger with Brazil's TAM, as well as home to low-cost challengers Sky Airline and JetSmart.
A major concession-led expansion delivered the large new Terminal 2 for international flights, opened in stages during 2021 and 2022, roughly doubling the airport's capacity while the original building became a domestic terminal. Santiago now offers nonstop flights to North America, Europe, Oceania. The South Pacific, including the storied link to Easter Island, one of the most isolated scheduled destinations on the planet.
