In 1967, Richard A. Henson joined with US Airways predecessor Allegheny Airlines in the nation's first codeshare relationship.[2] The term "code sharing" or "codeshare" was coined in 1989 by Qantas and American Airlines,[3] and in 1990 the two firms provided their first codeshare flights between an array of Australian cities and U.S. domestic cities. Code sharing has become widespread in the airline industry since then, particularly in the wake of the formation of large airline alliances.
