الخطوط الجوية الجزائرية
A joint venture between Air Algérie (49%) and Sonatrach (51%) in 1998 established the passenger airline company Tassili Airlines. Commercial services were launched on 8 April 1999 with a flight from Hassi Messaoud to Algiers. In 2005, Air Algérie withdrew its funds in the airline, which thus became wholly owned by Sonatrach. In 2006, Sonatrach gave Tassili Airlines permission to expand its domestic destinations and for the future opening of international routes.
