Air Inter (Lignes Aériennes Intérieures) was a semi-public French domestic airline.
Air Inter was incorporated in 1954. It operated its first commercial flight in 1958. However, it was 1960 when the airline started regular commercial services. The company established its operational and engineering base at Paris-Orly Airport. Air France and SNCF, the state railway company, were Air Inter’s two largest public sector shareholders. UTA was its largest private sector investor.
In 1990 Air Inter, with UTA and Air France, became part of an enlarged Air France group, which in turn became a subsidiary of Groupe Air France. Air Inter changed to Air France Europe following a merger with Air France and UTA. In 1997, it was absorbed into Air France.
