Société Aigle Azur Transports Aériens is an airline with its head office in Tremblay-en-France, France, near Paris, it is currently the second largest airline in France, behind the Air France Group. It operates domestic scheduled passenger services and international services to Algeria, Mali, Portugal, Senegal and France. It also operates charter, cargo and wet lease services. Its main bases are Orly Airport, Paris. Aigle Azur is also accredited by IATA with the IATA Operational Safety Audit (IOSA) for its safety practices.

In April 1946, Sylvain Floirat established the original Aigle Azur as one of the first wholly privately owned, independent airlines in post-war France. Between 1946 and 1955, the airline operated a large fleet of Douglas DC-3s.

During the early 1950s, Aigle Azur began operating long-haul scheduled routes linking metropolitan France with Africa and the Asia-Pacific region. France's Ministry of Public Works and Transport had transferred Air France's traffic rights for these routes to the country's newly created independent airlines, including Aigle Azur.

In 1970, the airline was re-constituted as a regional airline named Lucas Aviation. The re-formed airline's corporate and operational headquarters was at Paris Pontoise Airport, located in Boissy l'Aillerie. Lucas Aviation initially traded as Lucas Air Transport and operated regional scheduled services, including a year-round operation linking Deauville with London Gatwick. The name subsequently changed once more to Lucas Aigle Azur.
