AeroSur

AeroSur (legally incorporated as Compañía Boliviana de Transporte Aéreo Privado Aerosur, S.A.) was the second largest privately owned airline in Bolivia, headquartered in Santa Cruz de la Sierra. It operated a domestic and international flight network from its main hub at Viru Viru International Airport to major cities in Bolivia and destinations in South America, the United States and Spain. Founded in April 1992 taking advantage of the deregulation of Bolivia's air transport, it started flying on 24 August that year between Santa Cruz and Potosí. For most of its operational history, AeroSur's main fleet was the Boeing 727-200. The airline even operated the type for its services to Miami, requiring a refueling stop due to its range. They were gradually replaced with more modern Boeing 737 aircraft. Additionally, the airline operated single Boeing 747 and 767 aircraft for its long-haul destinations to North America and Europe. In 2008, AeroSur became Bolivia's flag carrier following the demise of the country's main airline, Lloyd Aéreo Boliviano, which ceased operations in 2010. In 2012, the airline declared bankruptcy and ceased operations shortly afterward; it had 1,200 employees at the time.
