DALLAS — Before we claim that the US airline industry resembles an oligopoly, we must first understand what the term means.
An oligopoly is a market structure in which a small number of large companies work to dominate a specific market segment, either explicitly or implicitly. This is normally done through collusion, and due to the limited competition between these firms, each firm can influence the others through their actions.
Firms in oligopolistic markets set prices but do not compete on price; however, they use advertising to ensure that their products are uniquely identifiable (oligopolies are known for having undifferentiated products).
Products in an oligopoly typically provide the same benefit to consumers. Other characteristics of oligopolies include increased barriers to entry and maximized revenue. Economic and legal factors can create or destroy oligopolies.
In terms of the aviation sector, deregulation policies can be seen as the turning point for the industry and the precise point where the industry became an atypical oligopoly.

Consequences of the Airline Deregulation Act of 1978
The federal government took control of the economic underpinnings of the US airline industry in 1938, and thus the industry was considered a public utility, much like electric power companies.
The Civil Aeronautics Board (CAB) was established at the time as a governing agency responsible for regulating the economic aspects of airline operations. The CAB had five members with six-year terms, appointed by the president (with the consent of the Senate). With its 750 employees (on average), the CAB conducted its duties until its dissolution in 1984, after the deregulation act was passed.
On October 24, 1978, the Airline Deregulation Act of 1978 (ADA) was passed, and air travel in the United States was thus revolutionized.
The law did not completely erase regulatory measures in the industry. It reduced the regulatory blanket gradually over the years until 1984. By then, CAB’s standing functions had been transferred to the Department of Transportation (DOT).
In its reign, the CAB decided how many airlines and which airlines would conduct operations on a particular route. To enter the market, airlines had to gain certification from CAB outlining the routes that must be followed. The exit was also controlled, and it required the carrier to receive CAB approval before cutting services to a city.
This massive shift in the industry was mostly contained in the US, but by the mid-1980s, Canada and Western Europe began adapting these deregulation policies; the rest of the world joined this movement in the mid-1990s, but not without resistance by various governments and foreign airlines.
Despite the fact that the airlines were not subject to stringent government regulations, they faced the same financial and economic challenges as any other business. They include, among other things, managing staffing issues, cost analyses, leveraging financing instruments, and maintaining brand loyalty, which must still be considered.
As one example, apart from suffering from repeated instances of financial mismanagement, TWA failed because the airline couldn’t effectively compete with new competitors after the airline deregulation act of 1978. These new airlines would reside in a special economic environment, and these characteristics would end up labeling the industry as an atypical oligopoly.
