Aerolíneas Argentinas
Following the acquisition of Austral by the Argentine government in 1980, both Aerolíneas Argentinas and Austral became government-owned, to the extent that some routes were simultaneously operated, even using similar equipment. However, a state of continuous tension existed over salary differences between both companies that eventually led the Aerolíneas Argentinas' pilots to a three-week-long strike that started on 1 July 1986. During this strike, the government leased pilots from the Argentine Air Force to operate some aircraft. Other companies took advantage from this situation and gained the market share Aerolíneas Argentinas lost, as domestic routes were operated by Austral, LADE, and LAPA, and the government temporarily authorised foreign carriers to exploit the company's international routes.
