From Wikipedia, the free encyclopedia.
Japan Air System (JAS, 日本エアシステム) was the smallest of the Big 3 Japanese airlines. Unlike competitors JAL and ANA, it flew only domestically. Its IATA designator was JA.
The company was originally formed as TOA Domestic Airlines (TDA) in a merger between TOA Airways and Japan Domestic in 1971. In 1988 the current name Japan Air System (JAS) was taken up.
On October 2, 2002, Japan Air System merged with Japan Airlines to form a new holding company entitled Japan Airlines System (日本航空システム). The merger was officially completed on April 1, 2004 with the retirement of all JAS flight codes, check-in desks and plane liveries.
