An econometric analysis of domestic air traffic demand in regional airports: Evidence from India

The Indian aviation industry has a vast potential to grow to cater to its population and commerce through developing air transport services to the regional airports. This paper examines the possible determinants of domestic air traffic demand in Indian regional airports serving below three million passengers per annum. Using multiple regression analysis, we find that distance to the nearest airport and accessibility of the airport significantly affect traffic volumes in regional airports. This study also highlights the specificities of Indian regional airports.     

Do the regional growth effects of air transport differ among airports?

This paper empirically studies the contribution of air transport to regional economic development in Germany. We find that the scale and direction of output effects of air services and airport infrastructure differ among airports. These differences are driven by ‘opportunity costs’ of airport capital and by positive output effects from air transport connectivity. We argue that the latter impacts potentially depend on traffic characteristics.     

A systematic approach to assess the effectiveness of airport noise mitigation strategies

Regional airports are often located very close to the urban area they serve and the increasing traffic rate that many of them have experienced in the last years has produced several impacts on the communities living close to the airport area, mainly aviation noise. If not properly managed, noise impacts produced by airport operations can cut down significantly the development of airport air traffic with direct effects on the economic and territorial systems. Aeronautical noise has greatly reduced in the last decade, due to aircraft design technological improvements and more severe regulations. However, the noise reduction during a single event does not make the issue of the airport location – and then the whole noise impact – less significant. This paper proposes an assessment process to evaluate the effects of actions adopted to reduce airport noise impacts on populated areas. Both airport-related factors – such as number of take-off; day-evening-night distributions of movements; aircraft type; flying paths – and land-use characteristics have been considered and combined in a density index that synthesizes the impacts of airport noise on the territory. The assessment process has been tested on a real case, the airport of Bologna in Northern Italy. The predicted results, compared with available real data for the test case, are significant and encourage the use of the proposed assessment process as decision support system for the airport management.     

Air transport liberalisation and airport dependency: developing a composite index

Air transport liberalisation in Europe has produced some major changes to the networks operated by airlines and the services available at airports. Within this context the degree of airport dependency in terms of market, spatial and temporal concentration is important to know from an economic geography and risk management perspective. A composite index called the Airport Dependency Index (ADI) is developed to measure airport dependency based on the concept of the relative Gini coefficient. Liberalisation has had varying impacts depending on the size and type of airport and so a comparison is made of the degree of dependency at a large sample of European airports using the ADI. The ADI has the potential to provide insight on the sustainability and worthiness of financing airport projects, and on whether airports should diversify further their activities by investing in the growth and expansion of their network.     

The economic impact of aviation: A review on the role of market access

In recent decades, advancements in telecommunications and (air) transportation have driven globalisation processes. Consequently, policymakers and scholars view access to transportation as an essential prerequisite for economic development. For aviation, existing empirical studies have attempted to estimate the wider economic impacts from regional, country-level and global perspectives. However, no theoretical framework has yet been presented that comprehensively captures the full set of mechanisms by which aviation can contribute to economic development. Such a framework would cover both positive and negative regional impacts, as well as the mechanisms and spatial distribution behind them. In this paper, we use a New Economic Geography approach to comprehensively describe the impact mechanisms. We then apply this theoretical framework to an empirical study of metrics of air transport supply, which policymakers and researchers can use to assess how well airports and their surrounding regions are connected by means of the air transport network. The results of our analysis can inform scholars and policymakers on how air transport can shape economic geography and the productivity of economic systems. The results might also provide guidance for future empirical work on the wider economic impacts of air transportation.     

The role of London airports in providing connectivity for the UK: regional dependence on foreign hubs

In a context of ongoing debate about the future UK aviation policy and its implications for regional economic development, this paper discusses the role of London Heathrow and the South East airports in providing connectivity for the UK, with particular focus on the international markets that originate from regional UK airports. Using an MIDT dataset of worldwide passenger itineraries served by the European airport network during May 2013, we first establish whether London Heathrow can currently be considered the most important hub for the UK, in terms of traffic generation, connectivity, and centrality, while also measuring the dependence of UK regions on foreign airports and airlines to remain connected with the rest of the world. Results show that, despite the competition, London Heathrow benefits from its massive traffic generation to remain the most central gateway for overall UK air transport markets. However, when only regional markets are considered, significant dependence on foreign hubs appears in many destinations, particularly to Asia–Pacific or the BRIC countries where above 80% of passengers use transfer flights. These results fit nicely with the observed trends of seat de-concentration and hub-bypassing in the airline industry. While dependence on foreign hubs can be interpreted as a sign of vulnerability, there is also the argument that bypassing Heathrow allows regional airports to develop new markets and reduce the level of congestion in the London airport system.     

Is spatial dispersal the dominant trend in air transport development? A global analysis for 2006–2015

The economic performance of a city or region is considered to be intertwined with its air travel capability. It is thus important for planners and stakeholders to understand the changes in the global aviation network. This study investigates the global aviation network, taking 10 years worth's OAG data from the years 2006–2015 and examines whether a spatial dispersal trend dominates the development of the aviation industry. It considers the aviation network at the airport level, and the airport–city level, which may consist of one or more airports. After clarification of the various definitions of concentration, we find that there appears a trend toward a dispersal pattern in the global aviation network at the airport level. On the other hand, there appears a slight concentration at the airport–city level. Besides, there have been some major capacity expansions at airports in the Middle East and East Asia, while the capacities of some traditional hubs in Europe and North America have become increasingly constrained since the 2008 global financial crisis. Furthermore, our study provides further observations consistent with the phenomenon of bypassing of traditional hubs, especially mega-hubs. Competition for passengers among hubs and secondary airports, especially in multi-airport cities, is discussed.     

The role of regional airports and air services in the United Kingdom

This paper deals with the implications of the 1998 UK transport White Paper for regional airports and air services within the wider context of the promotion of an integrated and sustainable transport system. More specifically, the discussion initially addresses the political and business context of the development of air transport in the UK regions. Secondly, the recent trends defining that development are isolated, particular attention being paid to the increasing importance of supplier-led strategies in air transport and the segmented markets served by regional airports. Finally, the three, not easily reconciled, strands, which can be identified in the White Paper’s analysis of aviation are considered. These are: air transport's relationship with sustainable development; the integration of air transport with surface modes; and the contribution of air transport to regional economic growth.     

Large volcanic eruptions and their influence on air transport: The case of Japan

Our research purpose is to estimate the impact of large volcanic eruptions on air transport and discuss how to reduce their negative impact through emergency operations. In particular, we focus on East Asia, where ash from the eruptions impedes air transport. First, we use Collaborative Actions for Renovation of Air Traffic System (CARATS) Open Data that are provided by the Civil Aviation Bureau (CAB) of Japan and estimate how many flights will be affected by volcanic ash. Furthermore, we discuss the dispersal of the volcanic ash that was discharged by the large-scale eruptions of Mount Sakurajima. This crossed over the main part of Japan from west to east. Through a simulation, we found that a volcanic eruption that lasts 14 h would cause a substantial number of the airports, including the major gateway airports, in Japan to be shut down simultaneously. It would also cause half of the airports’ scheduled flights to be cancelled or diverted. Subsequently, based on the impact estimation, we discuss the possibility of provisionally parking aircraft outside the damaged areas. Our results suggest that the airports located in the northern Tohoku area and the New Chitose airport are the best to accept evacuation flights to avoid risks in aviation following a volcanic eruption.     

Business aviation in Germany: An empirical and model-based analysis

The primary role of large airports is to serve the general public with scheduled and charter air transport services, with a secondary role of providing direct air transport access to regional industry and to firms who operate their own fleets of aircraft. Because of the complexity of slot allocation procedures and increasing runway capacity problems at airports, there is a growing problem in realising this secondary function. Neighbouring regional airports could play a complementary role and cope with some of this growth in traffic. Here we quantify the distribution of growing business aviation demand between airports to explore potential ways of accommodating it at both major and nearby secondary facilities.     

Policy issues and planning of UK regional airports

The principal motivation for this paper is to examine the policy issues for UK regional airports within the air transport system with particular reference to airport airline relationships. The geography of airline route networks is considered a key factor that determines location of the pressure for infrastructure development. Regional airports policy is considered in this context. The problems of the resultant concentration of air traffic has largely been ignored up until now and so this paper seeks highlight the issues this presents to policy makers. The paper reviews the changing regional airport ownership patterns and examines a range of implications. It then explores the policy implications for the future regulation and development of the air transport system. The authors contend that regulation and the planning system are the only two remaining policy levers for government to guide privately owned airlines, privately owned airports and commercialised airports towards national policy goals.     

The implications of environmental costs on air passenger demand for different airline business models

Various environmental measures, including both regulations and fiscal instruments, have been used at airports globally to reduce the impacts of aircraft noise as well as aircraft engine emissions. Internationally, it is recognized that the costs of environmental and social externalities of air transport must be internalized and paid for by the aviation industry and its users. The use of noise related charges or taxes, which theoretically should be based on their respective social costs, has been proved to be effective at some European airports. This research aims to investigate the impacts of environmental costs, through environmental charges, on air passenger demand for different airline business models. The paper presents the mathematical models measuring the social costs of aircraft noise and engine emissions as a basis for setting up environmental charges. Six intra-European short-haul routes in two city pairs, namely London–Amsterdam and London–Paris, are selected for the empirical analysis. The environmental charges are then hypothetically applied to airlines with two different business models, full service carriers (British Airways and Air France-KLM) and low cost airlines (EasyJet). The results show that the potential percentages of demand reduction for both leisure and business passengers would be higher for Easyjet's markets, although with less environmental cost per passenger.     

Managing New Zealand's airports in the face of commercial challenges

This paper explores commercial issues surrounding managing airports in New Zealand. Airport managers face pressures from changing airport–airline relationships, low cost airlines, proposed new airports and the growing importance of non-aeronautical revenues in achieving commercial goals. New Zealand's airports have moved from an operating environment within which all the principal airports were owned and managed by central government to one where airports are run as commercial entities under a variety of ownership structures. New Zealand has a high dependence on air transport and for its size, a very developed regional airport network.     

Impact of pandemic control over airport economics: Reconciling public health with airport business through a streamlined approach in pandemic control

Rapid aviation commercialisation and upsurge in worldwide affluence created a new avenue for disease proliferation across countries at an unprecedented rate. Epidemic and pandemic occurrences over the last decade demonstrate airports' role in disease transmission; while also exhibiting their importance as containment nodes. Tremendous amount of resources and effort are necessary to achieve the latter but inevitably, disrupt normal operations. The contrasting objectives between public health authorities and airport authorities result in compromising measures for both parties. Broadly similar controlling measures were adopted by various airports during outbreaks in the last decade. Their effectiveness have been analysed in terms of disease control; economic impact to airports were, however, not quantified. This paper concludes that more efficient airport pandemic control plans cause less severe economic impact on airports during pandemic and recommends a streamlined approach that improves overall effect of pandemic control while minimising economic impacts to airport businesses.     

The Air Liberalisation Index as a tool in measuring the impact of South Africa's aviation policy in Africa on air passenger traffic flows

In Africa, the Yamoussoukro Decision (YD) to date remains the single most important air transport reform policy, the continent-wide implementation of which remains pending. This study employs the Air Liberalisation Index (ALI), developed by the Word Trade Organisation (WTO) Secretariat, to measure the impact of each of the seven quantifiable market access features of South Africa's aviation policy in Africa on air passenger traffic flows. A fixed one-way panel regression technique was applied to panel data, representing five air transport markets: intra-African, the SADC, East African, West African and North African over two time periods (2000–2010; 2006–2010). The results proved to be significant in three markets, intra-African, the SADC and East African and provide new insights into the relationship between air passenger traffic flows and aviation policy in the South African – intra-African and regional contexts.     

Airports in their urban settings: towards a conceptual model of interfaces in the Australian context

In Australia, airports have emerged as important sub-regional activity centres and now pose challenges for both airport operation and planning in the surrounding urban and regional environment. The changing nature of airports in their metropolitan context and the emergence of new pressures and problems require the introduction of a fresh conceptual framework to assist the better understanding of these complex roles and spatial interactions. The approach draws upon the meta-concept of interfaces of an ‘airport metropolis’ as an organising device consisting of four main domains: economic development, land use, infrastructure, and governance. The paper uses the framework to further discuss airport and regional interactions and highlights the use of sustainability criteria to operationalise the model. The approach aims to move research and practice beyond the traditionally compartmentalised analysis of airport issues and policy-making by highlighting interdependencies between airports and regions.     

Effects of competition and policy changes on Chinese airport productivity: An empirical investigation

This paper investigates the influence of competition and aviation policy reform (for example, the airport localization program and listing airports on stock markets) in China on the efficiency of Chinese airports. By using Data Envelopment Analysis, we estimate both the productivity level and its growth for 25 sample Chinese airports. After controlling for hub status and other airports' characteristics, we find that: (i) publicly listed airports are significantly more efficient than non-listed airports; (ii) airports with more competition are more efficient than their counterparts; (iii) the airports' efficiency and the technical progress are positively correlated with the airport localization program; and (iv) the impacts of open-skies agreements and airline mergers on the airports' efficiency are statistically insignificant.     

From hub to tourist destination – An explorative study of Singapore and Dubai's aviation-based transformation

The growth of air transport networks and deregulation have allowed small, low-populated places like Singapore and Dubai to become major international tourism destinations. Both have used tightly combined airline, airport and tourism strategies to help achieve this. Here we analyse developments in Singapore and Dubai by examining interactions between their airlines, airports, governments and tourism authorities, and how integrated management strategies leveraged their aviation traffic hubs to develop tourism destinations.     

Negotiate-arbitrate regulation of airport services: Twenty years of experience in Australia

Negotiate-arbitrate regulation has played a role in the economic regulation of airports in Australia since the introduction of a national access regime in 1995. Over a twenty year period there have been three cases where negotiate-arbitrate regulation (NAR) has been applied to airport services, two cases where a decision has been made to not apply negotiate-arbitrate regulation to services provided and a case where an airline has sought to apply NAR and then withdrawn its application. The experience of the application of NAR to airport services is examined against a background discussion on issues associated with countervailing power in airport services. Based on the experience, some observations are made which reflect advantages and disadvantages of the application of NAR to airport services. NAR has provided a targeted approach to economic regulation of airport services in Australia, involving negotiated outcomes and limited intrusion into the aviation markets.     

Japanese-airport benchmarking with the DEA and endogenous-weight TFP methods: testing the criticism of overinvestment in Japanese regional airports

As aviation demand increased constantly along with the rapid economic growth in Japan and surrounding East Asian countries over the last several decades, Japanese government promoted airport construction since 1950s. However, the recent change in the economic background has made rise to a criticism toward the inefficient public investment, especially the transportation infrastructure. In this criticism, it has been argued that some of the small regional airports are indeed suffering the issue of overinvestment. Thus this paper attempts to verify the validity of such criticism by statistically measuring the efficiency of Japanese airports and conducting comparative analysis. For this objective, the paper employs two distinct methods namely data-envelopment analysis and endogenous-weight TFP methods. The results from these methods consistently indicates that the efficiency of regional airports in mainland Japan are lower than others, and that those airports constructed in the 1990s are relatively inefficient.
