Cubana de Aviación S.A., commonly known as Cubana, is a national airline based in Cuba, as well as the country's largest airline. It was founded in October 1929 (1929-10), becoming one of the earliest airlines to emerge in Latin America. It has its corporate headquarters in Havana, and its main base is located at José Martí International Airport. Originally a subsidiary of Pan American World Airways and later a private company owned by Cuban investors, Cubana has been wholly owned by the Cuban government since May 1959 and celebrated its 80th anniversary in 2009.
