El Dorado International Airport (IATA: BOG, ICAO: SKBO) is an international airport serving Bogotá, Colombia and its surrounding areas. The airport is located mostly in the Fontibón district of Bogotá, although it partially extends into the Engativá district and the municipality of Funza in the Western Savanna Province of the Cundinamarca Department. In 2017, it served almost 31,000,000 passengers, 770,000 metric tons of cargo, and 304,330 aircraft movements. This makes El Dorado the third busiest airport in Latin America in terms of passenger traffic, the second busiest in terms of aircraft movements, and the busiest in terms of cargo. El Dorado is also by far the busiest and most important airport in Colombia, accounting for just under half (49%) of the country's air traffic. El Dorado is a hub for the Colombian flag-carrier Avianca, LATAM Colombia, Satena, Wingo, and a number of cargo companies.
