The Airline Deregulation Act of 1978 was a transformative piece of legislation that shifted control of the aviation industry from the federal government to the free market. Prior to 1978, the Civil Aeronautics Board regulated routes, fares, and market entry, which kept ticket prices high and competition low. Following deregulation, airlines were free to set their own prices and fly wherever they chose, leading to the birth of the "hub-and-spoke" system and the rise of low-cost carriers like Southwest. For the travel and tourism industry, this meant a massive democratizing effect; flying was no longer a luxury reserved for the elite. As competition intensified, airfares dropped significantly in real terms, allowing millions more people to travel for leisure. This surge in passengers fueled the rapid expansion of hotel chains, car rental agencies, and theme parks across the United States. However, it also led to the consolidation of the industry, the disappearance of several legacy "flag" carriers, and a shift toward more crowded cabins and fewer "frills" as airlines prioritized cost-efficiency over passenger comfort to survive.
