Effects[edit]
See also: Airline deregulation
A 1996 Government Accountability Office report found that the average fare per passenger mile was about nine percent lower in 1994 than in 1979. Between 1976 and 1990 the paid fare had declined approximately thirty percent in inflation-adjusted terms. Passenger loads have risen, partly because airlines can now transfer larger aircraft to longer, busier routes and replace them with smaller ones on shorter, lower-traffic routes.[citation needed]
However, these trends have not been distributed evenly throughout the national air transportation network. Costs have fallen more dramatically on higher-traffic, longer-distance routes than on shorter ones.
Exposure to competition led to heavy losses and conflicts with labor unions for a number of carriers. Between 1978 and mid-2001, eight major carriers (including Eastern, Midway, Braniff, Pan Am, Continental, Northwest Airlines, and TWA) and more than 100 smaller airlines went bankrupt or were liquidated—including most of the dozens of new airlines founded in deregulation's aftermath.[citation needed]
For the most part, smaller markets did not suffer the erosion of service predicted by some opponents of deregulation. However, until the advent of low-cost carriers, point-to-point air transport declined in favor of a more pronounced hub-and-spoke system. A traveler starting from a non-hub airport (a spoke) would fly into the hub, then reach the final destination by flying from the hub to another airport, the spoke. While more efficient for serving smaller markets, this system has enabled some airlines to drive out competition from their "fortress hubs." The growth of low-cost carriers such as Southwest Airlines has brought more point-to-point service back into the United States air transport system, and contributed to the development of a wider range of aircraft types that are better adaptable to markets of varying sizes.[citation needed]
In 2011, Supreme Court Justice Stephen Breyer (who worked with Senator Kennedy on airline deregulation in the 1970s) wrote:
What does the industry's history tell us? Was this effort worthwhile? Certainly it shows that every major reform brings about new, sometimes unforeseen, problems. No one foresaw the industry's spectacular growth, with the number of air passengers increasing from 207.5 million in 1974 to 721.1 million last year. As a result, no one foresaw the extent to which new bottlenecks would develop: a flight-choked Northeast corridor, overcrowded airports, delays, and terrorist risks consequently making air travel increasingly difficult. Nor did anyone foresee the extent to which change might unfairly harm workers in the industry. Still, fares have come down. Airline revenue per passenger mile has declined from an inflation-adjusted 33.3 cents in 1974, to 13 cents in the first half of 2010. In 1974 the cheapest round-trip New York-Los Angeles flight (in inflation-adjusted dollars) that regulators would allow: $1,442. Today one can fly that same route for $268. That is why the number of travelers has gone way up. So we sit in crowded planes, munch potato chips, flare up when the loudspeaker announces yet another flight delay. But how many now will vote to go back to the "good old days" of paying high, regulated prices for better service? Even among business travelers, who wants to pay "full fare for the briefcase?"[6]
