Combined with the Staggers Act , intermodal freight transport surged, expanding 70 percent between and Deregulation allowed manufacturers to reduce inventories, to move their products more quickly, and to be more responsive to customers. Consumers indirectly benefited from the more efficient, lower-cost transport of goods, according to a comprehensive study from the Department of Transportation. From Wikipedia, the free encyclopedia.

The Politics of Deregulation. Washington, D. Organization for Economic Cooperation and Development. International Conference. November Belzer, Michael H. Just 12 years after the debut of the seat in a typical two-class configuration B, the seat in a typical three-class configuration B made its maiden flight. However, by the s, the majority of the Bs were being retired and replaced by longer range and more fuel-efficient twin-engine aircraft such as the B, the A, the B and the A On transpacific routes, the , for instance has a fuel economy of about 39 passenger-kilometers per liter of jet fuel versus about 23 passenger-kilometers per liter for the Boeing ER.
The triumph of widebody twinjets is most evident in the transatlantic and transpacific markets. However, the A is facing a much more limited range of airports due to its technical requirements of longer runways and gate access. Air transportation is now overwhelmingly dominant in transcontinental and intercontinental travel and has become more competitive for shorter trips in many regional markets. Since then LCCs have proliferated across developed markets and more recently in emerging markets too.
In developing countries, the ascent of LCCs has been fueled in part by the poor quality of land transportation and at times security issues. Since the end of Concorde services, the fastest airliners in regular use have had cruising speeds about as fast as the Bs of the early s. However, the introduction of long-haul aircraft has produced new rounds of time-space convergence.
For instance, in , twenty US cities had nonstop services to at least one destination in Asia, up from 13 US cities in Boston had nonstop links to Tokyo, Beijing, Shanghai, and Hong Kong in whereas two decades earlier all of those markets would have required a time-consuming connection at a larger hub. Meanwhile perhaps the most significant improvement in aviation is the reduced the risks of accidents. If civil aviation had had the same accident rate per million departures as in the early s, there would have been about three fatal accidents somewhere in the world per day in Instead, there were nine fatal accidents worldwide for the whole year.
More generally, despite the expansion of long-haul flights and the increased globalization of the economy, short-haul flights predominate. Typically, air transportation is most important for time sensitive, valuable or perishable freight carried over long distances. Air cargo is also vital in emergencies when the fast delivery of supplies prevails over cost issues. Air transportation has transformed society on the ground at scales ranging from the local to the global.
Aviation has made the everyday life in many parts of the world faster, more interconnected, more varied, and more affluent; but those gains have come at the expense of significant environmental challenges. The acceleration of the material world. As the fastest mode for most kinds of traffic, air transportation has been associated with the speeding up of daily life.
This effect is most apparent with the astonishing delivery times for goods ordered online from sites such as Amazon.
In , Amazon offered two-day deliveries to the all of the US for millions of goods and next-day delivery for a narrower range of goods. In , Amazon began flying its own aircraft as Amazon Air in the United States, with flights operating nationwide. People too move at faster speeds. The Concorde was grounded in , but the multiplication of nonstop sectors means that, even at transonic speeds close to but not beyond the speed of sound the world is smaller for passengers; the number of unique city-pairs served by commercial airlines grew to 22, in , about twice the number of twenty years earlier.
The speed of human transportation has changed how people interact in ways that are both positive and negative. For instance, until the advent of low-cost air transportation, the principal means of traveling between Ho Chi Minh City and Hanoi was by a to hour rail journey on the Reunification Express or a similarly tedious bus journey. Now, for most people, the cities are just 2 hours apart, and the route has become among the most densely trafficked in the world, with 60 flights per day each way in On the other hand, the acceleration of people around the world has also sped up the diffusion of infectious disease.
Ultimately, cases were reported in more than two dozen countries over a matter of weeks, with airports becoming the key frontiers in trying to limit the spread of SARS. Before aviation became widespread, the sheer size of the world afforded a degree of protection from the development of pandemics.
But the world is, at least measured in terms of time, much smaller than a century ago. An interconnected world. At any given moment in , an estimated 1. At the global scale, increasingly long-haul nonstop services up to 18 hours in duration are both a response and a driver for globalization. Most of the nodes for such flights are world-cities, the command-and-control centers of the global economy.
Yet the links between globalization and the airline industry extend far beyond the main hubs.
Manufacturers, especially those producing high-value electronics, are heavily reliant upon air transport to tie together spatially disaggregated operations. For example, by , Zhengzhou, capital of Henan Province in China and the largest production base for Apple iPhones, was linked by numerous freighter aircraft flights each day to global markets, including a nonstop freighter flight by Cargolux to faraway Luxembourg.
In addition to the trade networks established by multinational corporations, there are also extensive social networks established by migrants involving recurring air travel. The flow of people between Ethiopia and Washington, DC is one strand in the larger tapestry of global connections expedited by air transportation.

A kaleidoscope of experience. Cheap air transport has enlarged the geographic scope of everyday life and in so doing has enriched the lives of many with unprecedented variety. Take first the variety of goods; by one common measure, the US imported more than four times the variety of goods in as in Much of the increase was attributable to the sharp reduction in transportation costs through containerized shipping, but lower cost air cargo has also played a role. These markets largely did not exist a few decades ago. Efficient and affordable air cargo has contributed to changes in diet by making available new products or products in seasons during which they would not be available, to changes in retailing, and correspondingly to changes in manufacturing.
Examples abound, such as fresh produce grown in the southern hemisphere available in the northern hemisphere during winter a phenomenon sometimes referred to as permanent global summertime — at least for affluent consumers. Likewise, air transport has been a catalyst to the emergence of an ever-greater variety of tourist destinations. The markets with the fastest growth in passengers between and were Egypt partly due to a recovery from an earlier terrorism-related fall in visitors , Togo, Vietnam, and Georgia.
All of these markets rely overwhelmingly on air arrivals. The ascent of affluence. Air traffic is correlated with per capita income, but the relationship works both ways: richer populations can more easily afford what is usually the most expensive mode, but aviation has also been catalytic to the growth of economies. In , airlines flew approximately 4. The total volume of air passengers equaled nearly 60 percent of the global population, but of course a much smaller share are actually air travelers as individuals who use air transportation usually do so several times per year.
The propensity to fly is therefore highly uneven, as observed in the passengers and freight markets. Alone, North America and Europe. Alone, flights originating in North America and Europe accounted for 47 percent of airline seat capacity in , a share that has been declining in light of the growth in other regions of the world. For instance, flights from China accounted for 14 percent of seat capacity in , up from 3 percent in At the same time, however, lower transportation costs — in terms of both time and money — have encouraged faster income growth.
The economic impact of air transportation is most strongly pronounced near air hubs, but the catalytic effect of air accessibility extends across the economy. Whole sectors of the economy are strongly dependent on aviation, logistics, advanced business services such as consulting and advertising, and tourism are among the industries for which air accessibility is vital.
The high costs of aviation. Yet the huge increase in traffic in Orlando and the more modest increase globally have not been cost-free. In particular, aviation externalities have risen with traffic volumes. The air transport sector accounted for about 2 percent of greenhouse gas emissions in , and that share is forecast to rise to 3.
Aviation is heavily dependent on fossil fuels and is likely to remain so after other modes have transitioned to more environmentally friendly fuel sources. Some airlines have experimented with biofuels, but their impact remains marginal so far. Between and , about , flights were partly powered by biofuels, but there were more than , flights per day powered solely by conventional fuels in Air transportation is overwhelmingly dominant in transcontinental and intercontinental travel and is becoming more competitive for shorter trips in many regional markets.

In the United States, for instance, air travel is the most important mode for trips more than about 1, kilometers. In developing countries low cost carriers are proliferating as well, bringing air fares lower and attracting more passengers, particularly because of the poor quality of land transportation and at times security issues.
Aviation also has significant impacts at the local level, including emissions of nitrogen oxides and particulate matter. As with greenhouse gasses however, emissions growth at least when measured per passenger-kilometer has been stemmed by rapid improvement in aviation technology — especially improvements in engine efficiency. The average fuel burn per passenger-kilometer by air transportation fell by 45 percent between and , and the introduction of a new generation of jet engines portends further gains. The most obvious externality at the local scale is aircraft noise, and again technology has brought impressive gains.
Still, the huge increase in traffic volumes partly offsets this and other technical improvements in aviation. Typically, air cargo relates to time sensitive, valuable or perishable freight carried over long distances.

Air cargo has also a niche market for emergency situations where the fast delivery of supplies prevails over cost issues. While the air travel time for an air cargo supply chain is usually about half a day, the ground processing can take about 5 days two and a half day at the airport of origin and two and a half day at the airport of destination. The air freight market is serviced by five types of operations:. Efficient and affordable air freight has contributed to changes in diet by making available new products or products in seasons during which they would not be available, to changes in retailing and correspondingly to changes in manufacturing.
Examples abound, such as fresh produces growth on the southern hemisphere available in the northern hemisphere during winter, or merchandises purchased online and shipped promptly by air transport or a computer manufacturer depending of the global shipment of various components in the manufacturing and assembly processes. The increased importance of time-based competition ensures that air cargo augurs well for the future growth of air transportation. Theoretically, air transport enjoys greater freedom of route choice than most other modes and so airline routes span oceans, the highest mountains chains, the most forbidding deserts, and other physical barriers to surface transport.
Yet while it is true that the mode is less restricted than land transport to specific rights of way, it is nevertheless much more constrained than what might be supposed. Weather events such as snowstorms and thunderstorms can temporarily create major disruptions that cascade through hub-and-spoke networks.
Volcanic eruptions may also impede air travel by releasing ash in the atmosphere, which can damage and even shut down turbofan engines. Fear of such calamities, forced the closing down of the airspace in much of Europe as well as the North Atlantic for nearly a week following an April volcanic eruption. The suspension of services represented the largest natural disruption of air travel in history.
Motor Carrier Act of 1980
On a more regular basis, meanwhile, aircraft seek to exploit or avoid upper atmospheric winds, in particular the jet stream , to enhance speed and reduce fuel consumption. Yet the limitations that structure air transportation are mainly human creations , especially internationally.
The Chicago Convention of established the basic geopolitical guidelines of international air operations, which became known as the freedoms of the air. First right to overfly and second right for a technical stop freedom rights are almost automatically exchanged among countries. The US, which emerged from World War II with by far the strongest airline industry in the world, had wanted third and fourth freedom rights the right to drop off passengers and cargo and the right to pick up passengers and cargo, respectively, in another country to be freely exchanged as well.
Instead, these and the other rights have been the subject of hundreds of carefully negotiated bilateral air services agreements ASAs. In an ASA, each side can specify which airlines can serve which cities with what size equipment and at what frequencies. ASAs often include provisions that also regulate fares and the sharing of revenue among the airlines serving a particular international route.
