航空放开管制 (Airline Deregulation)

What Is Airline Deregulation?

Airline deregulation refers to the dismantling of government controls over the commercial aviation market. In the United States, the Civil Aeronautics Board (CAB) had since 1938 controlled which airlines could fly which routes and what fares they could charge — a system that kept airfares high and service predictable but inefficient. The Airline Deregulation Act of 1978, signed by President Jimmy Carter on October 24, 1978, dismantled this framework, allowing market forces to determine routes, fares, and airline entry. The CAB itself was abolished in 1985.

Historical Context

The intellectual groundwork was laid by economists Alfred Kahn (who chaired the CAB during deregulation) and the work of the Brookings Institution, which demonstrated that intrastate carriers operating outside CAB jurisdiction — such as Southwest Airlines in Texas and PSA in California — offered fares 50–70% lower than comparable regulated routes. Senator Edward Kennedy held hearings in 1975 that built political momentum. The jet age had made aircraft productivity so high that artificially maintained fares represented a massive transfer from consumers to airlines and their unionized workforces.

Key Milestones

• October 24, 1978: Airline Deregulation Act signed into law (U.S.).
• 1981: Air traffic controllers' strike; Reagan's dismissal of PATCO reshapes labor relations.
• 1987: European Community begins liberalization; full EU single aviation market established by 1997.
• 1990s–2000s: Low-cost carriers — Ryanair, easyJet, Spirit — expand dramatically using models only viable under deregulation.

Legacy and Impact

Deregulation produced profound structural changes. The hub-and-spoke model emerged as the dominant network architecture: major carriers concentrated traffic through fortress hubs, enabling efficient connections but also market power. Ancillary revenue streams — baggage fees, seat upgrades, frequent flyer program sales — became essential to airline economics as base fares were competed down. The number of air travelers in the U.S. tripled between 1978 and 2000. Average inflation-adjusted airfares fell by over 40%. However, deregulation also produced waves of bankruptcies, mergers, and service withdrawals from smaller communities — a legacy that remains contested to this day.
