Gol Linhas Aéreas Inteligentes S.A is a Brazilian low-cost airline based in Rio de Janeiro, Brazil. According to the National Civil Aviation Agency of Brazil, between January and December 2019 Gol had 37.7% of the domestic and 3.8% of the international market shares in terms of passenger-kilometers flown, making it the largest domestic and third largest international airline in Brazil. Gol competes in Brazil and other South American countries primarily with LATAM Brasil, and Azul. It also owns the brand Varig, although now that name refers to what is informally known as the "new" Varig, founded in 2006, not to the extinct "old" Varig airline, founded in 1927. Gol operates a growing domestic and international scheduled network. Its main hubs are São Paulo–Guarulhos International Airport, Rio de Janeiro–Galeão International Airport and Tancredo Neves International Airport near Belo Horizonte. Gol also has focus operations at Rio de Janeiro-Santos Dumont Airport, São Paulo-Congonhas Airport, and Salgado Filho International Airport in Porto Alegre. Gol refers to itself as GOL Intelligent Airlines as a slogan. Wikipedia
