CASI was formed as the South-East Asia Division of Continental in April 1965 with operations starting in September 1965 using approximately 22, mainly STOL, aircraft. Continental formed CASI by paying over a million US dollars for BirdAir (Bird and Sons) and its 350 employees and 22 aircraft. CASI aircraft in Laos were registered as Air Continental. As of 1998 Continental Airlines still operated in the Pacific Islands. In 2010 Continental merged into United Airlines.
