Sao Paulo/Guarulhos International Airport opened in January 1985 on the grounds of the Cumbica air force base, built to relieve the overwhelmed Congonhas airport in the city center and Viracopos far to the west. Locals still routinely call it Cumbica.
The airport was later officially named for Andre Franco Montoro, a former governor of Sao Paulo state. From the start it took over Brazil's intercontinental traffic, growing with the country's economy to become the busiest airport in Brazil and the leading international gateway of South America.
Two terminals from the original design were progressively expanded. The transformative moment came in 2012, when the airport was concessioned to the private GRU Airport consortium. In 2014, when the modern Terminal 3 opened just in time for the FIFA World Cup hosted by Brazil.
Guarulhos became the principal hub of LATAM Brasil and a major base for Gol, while nearly every global long-haul carrier serving Brazil lands there. Today it combines dense domestic trunk routes with the continent's richest long-haul network. Its cargo terminal ranks among the most important in Latin America.
