The Airline Deregulation Act of 1978 has had a significant impact on the airline industry and its labor market. The structure of the airline labor market before the Act is examined in light of certain significant historical events including legislative intervention and regulatory practice. The Act and other coincident extraneous events are considered to show how deregulation and other unrelated economic and technological factors operated as a catalyst, sparking substantial short-term upheaval in the airline labor market. It is argued that in the longer term airline employees have little to fear from deregulation and that deregulation may eventually enhance labor’s position in view of the increased employment opportunities that an expanded market may bring and the abolition of the industry strike insurance scheme.
