History

Historical Context

The Airline Deregulation Act of 1978 marked a pivotal shift in the U.S. airline industry by eliminating government control over fares and routes, fostering competition. This led to a wave of mergers, with airlines like American Airlines capturing over 40% market share. Current merger discussions, such as between Alaska Airlines and Hawaiian Airlines, reflect the ongoing impact of deregulation on market dynamics and consumer choices.
