Tassili Travail Aérien (TTA) is an Algerian aviation company specializing in aerial work and technical flight missions. Headquartered in Algiers, it is a wholly owned subsidiary of the state energy group Sonatrach.
The company serves as the primary tactical aviation provider for Algeria's oil and gas infrastructure, public health emergencies, and environmental protection. While its former parent company, Tassili Airlines (now known as Domestic Airlines), transitioned to Air Algérie in 2025 to handle scheduled domestic passenger travel, TTA was retained by Sonatrach to focus exclusively on industrial and utility operations.[1][2]
History
Tassili Travail Aérien was established as a separate legal entity in 2011 to consolidate the "aerial work" (travail aérien) activities previously performed by its parent company, Tassili Airlines. In April 2014, the company received its independent Air Operator's Certificate (AOC) from the Algerian National Civil Aviation Agency (ANAC).[3]
