Airline deregulation refers to the process of removing entry and price restrictions on airlines. The United States led the way by passing the Airline Deregulation Act of 1978, which reduced regulations set by the Civil Aeronautics Board. This led to lower fares, more travel options, and the growth of frequent flyer programs. Deregulation in the US and Europe increased competition and route expansion. In Malaysia, deregulation allowed for growth of the low-cost carrier AirAsia alongside Malaysia Airlines, increasing competition and route options for consumers.
