A deterministic model was developed to study the effects of inefficient scheduling on flight delays at hub airports. The model bases the delay calculation on published schedule data and on user-defined airport capacities. Data from the Official Airline Guide of May, 1977 and May, 1985 was used for the analysis. Twelve large airports were studied in the hopes of finding a correlation between airport delay due to congestion and hubs. Data for both time periods was analyzed for the twelve airports in order to find historical trends in the growth of hubbing. Among the airports studied, those that were hubs had significantly more delays due to inefficient scheduling than the non-hubs, even for an equivalent number of operations. Also, these relative inefficiencies were shown to exist from hub to hub. Delays at hubs of similar size differed by up to 200 percent.

This study examines hub-carrier scheduling and hub-airport congestion pricing using a simple hub-spoke network model incorporating both schedule delays and congestion delays. We find that in the short-middle run, where aircraft size is given exogenously, hub-airport congestion tolls are not needed at the social optimum if the (negative) congestion delay effect is more or less offset by the (positive) schedule delay effect. In the long run, where aircraft size is decided endogenously, at the social optimum, it is not necessary to impose congestion tolls via a per-flight charge or via per-passenger charges. This is in stark contrast to the results of existing literature. Interestingly, we further find that when the per-flight charge is weight related, a profit-maximizing (privatized) hub airport imposes schedule and congestion delay costs via per-flight charges, but there are no delay cost terms in the private optimal per-passenger charges. However, when the per-flight charge is movement related, it imposes schedule and congestion delay costs via both per-flight charges and per-passenger charges. These “private” optimal congestion-pricing rules provide useful insights into privatized, or profit-maximizing/emphasizing, hub airports.

I study delays and congestion patterns in U.S. hub airports during periods of high flight volume. I find that these periods are longer when the share of flights operated by the hub airline is greater, and these longer periods exhibit shorter delays. These results lend support to recent theoretical work on congestion, implying that hub-airlines take into account the impact of their scheduling decisions on the congestion that they bear. The results may suggest that congestion management solutions implemented at hub airports dominated by one airline could have only a limited impact on congestion in general.

Network Effects Congestion Externalities And Air Traffic Delays written by Christopher J. Mayer and has been published by this book supported file pdf, txt, epub, kindle and other format this book has been release on 2002 with Air traffic control categories.

"We examine two factors that might explain the extent of air traffic delays in the United States: network benefits due to hubbing and congestion externalities. Airline hubs enable passengers to cross-connect to many destinations, thus creating network benefits that increase in the number of markets served from the hub. Delays are the equilibrium outcome of a hub airline equating high marginal benefits from hubbing with the marginal cost of delays. Congestion externalities are created when airlines do not consider that adding flights may lead to increased delays for other air carriers. In this case, delays represent a market failure. Using data on all domestic flights by major US carriers from 1988-2000, we find that delays are increasing in hubbing activity at an airport and decreasing in market concentration but the hubbing effect dominates empirically. In addition, most delays due to hubbing actually accrue to the hub carrier, primarily because the hub carrier clusters its flights in short spans of time in order to maximize passenger interconnections. Non hub flights at hub airports operate with minimal additional travel time by avoiding the congested peak connecting times of the hub carrier. These results suggest that an optimal congestion tax would have a relatively small impact on air traffic delays since hub carriers already internalize most of the costs of hubbing and a tax that did not take the network benefits of hubbing into account could reduce social welfare"--National Bureau of Economic Research web site.

Over the past several decades, commercial air traffic has been growing at a far greater rate than airport capacity, causing airports to become increasingly congested. How can we accommodate this increased traffic and at the same time alleviate traffic delays resulting from congestion? The response outside the US has been to set a maximum number of slots and use administrative procedures to allocate these among competing airlines, with the most important consideration being 'grandfather rights' to existing carriers. The United States, on the other hand, has used administrative procedures to allocate slots at only four airports. In all other cases, flights have been handled on a first-come, first-served basis, with aircraft queuing for the privilege of landing or taking off from a congested airport. While recognizing the advantages of slot systems in lessening delays, economists have criticized both approaches as being sub-optimal, and have advocated procedures such as slot auctions, peak-load pricing and slot trading to better utilize congested airports. Edited by an international team of air transport economists and drawing on an impressive list of contributors, Airport Slots provides an extremely comprehensive treatment of the subject. It considers the methods currently used to allocate slots and applies economic analysis to each. The book then explains various schemes to increase public welfare by taxing or pricing congestion, and describes alternate slot-allocation schemes, most notably slot auctions. In addition, Airport Slots outlines the complexities involved in slot-allocation methods, including the requirement for multiple slots - a take-off slot at London Heathrow is useless unless there is a landing slot available at Frankfurt for a London Frankfurt flight. Finally, the book explores the economic pitfalls of slot-allocation schemes; for example, controls may not be required if external delay costs are internalized by a dominant carrier at its hub. Airport Slots provides a valuable contribution to the debate on how best to limit airport congestion. The book's comprehensive treatment of the subject matter provides the reader with a 'one-stop' volume to explore airport congestion and slot-allocation schemes, offering valuable insights to academics and practitioners alike.
