Boliviana de Aviación, legally incorporated as Empresa Pública Nacional Estratégica Boliviana de Aviación and commonly known as BoA, is the flag carrier airline of Bolivia and is wholly owned by the country's government. Founded in October 2007 and headquartered in Cochabamba, it operates most of its domestic network out of its primary hub at Jorge Wilstermann International Airport and maintains focus cities at El Alto International Airport and Viru Viru International Airport. Almost all international flights, including long-haul services to Madrid and Miami, operate out of Viru Viru airport in Santa Cruz de la Sierra due to the severe limitations of El Alto International Airport in La Paz, located over 4,000 metres (13,000 ft) above sea level.

A flag carrier is a transport company, such as an airline or shipping company, that, being locally registered in a given sovereign state, enjoys preferential rights or privileges accorded by the government for international operations.
