Africa’s single aviation market: The progress so far

To promote the development of air transport at the continental level, several policies were introduced, leading to the Yamoussoukro Decision (YD) in late 1999, which had the liberalisation of the intra-African aviation spaces as its main objective. Even though notable progress has been achieved towards more market-oriented aviation policies, at the pan-African level some markets are still restrictive and inconsistent with the YD, particularly with respect to the granting of 5th freedom rights. This paper aims to examine recent developments in the aviation sector in Africa, with a focus on the implementation of the YD. The obstacles to liberalisation are discussed and several measures for facilitating Africa’s move towards multilateral open skies are investigated. These include, among others, a greater collaboration and co-operation among African airlines, as well as between African airlines and foreign ones; redefinition of the role and responsibilities of different institutions which are instrumental in implementing the YD and some further issues such as ownership guidelines.     

‘Africanisation’ of South Africa’s international air links, 1994–2003

In the first decade of democratic rule in South Africa scheduled commercial passenger flights across the country’s borders more than doubled. Additional flights served new African air passenger markets and secondary airports in established markets. Overseas flights increased more slowly, serving a diminishing number of overseas countries and cities. In 1994 the Republic was linked directly by air with more overseas than African countries and cities; within a decade the pattern reversed. The changing geography of South Africa’s international air links reflects developments in the international airline industry, and South Africa’s increasingly prominent political and commercial role in Africa.     

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.     

The causal relationship between air transport and economic growth: Empirical evidence from South Asia

This paper examines the causal relationship between air transport and economic growth in the South Asian context. Using panel data over a period of 42 years (1973–2014), we apply Pedroni/Johansen cointegration test methods, followed by Granger long-run and Wald short-run causality tests. To allow for spatial heterogeneity we then apply Time Series Cross Section (TSCS) Granger causality tests for each of the eight analysed countries separately. Our results confirm a long-run uni-directional Granger causality which runs from GDP to air passenger traffic and also to air freight volumes. Contrary to the existing literature we do not find a long-run bi-directional causality which confirms that spatial dimensions and context matter (i.e. low income and large populations). The absence of short-run causality and the identified time lags of 3–4 years should guide aviation firms and policy makers in the preparation of necessary infrastructure required to support the strong air transport growth potential.     

Connecting African urban areas: airline networks and intra-Sub-Saharan trade

Despite efforts to enhance the efficiency of the African air transportation sector through such actions the Yamoussoukro Decision, African represents less than 2% of the world’s air passenger kilometers. This is despite the fact that air transportation can act as a means of transporting traded goods directly (including the individuals that are the “product” of tourism) and provide complementary services of labor mobility for those engaged in the production of more bulky goods that are shipped by land and maritime modes. We examine the network of intra-Sub-Saharan African airline connections to highlight the differential access enjoyed by the region’s largest cities. Second, we develop a quantitative framework linking the availability of air connections to the main international trade flows in sub-Sahara Africa. Our findings suggest that, although there is a positive link between air transportation and economic development in Africa, the multilateral efforts at reducing institutional impediments to more open aviation markets have not produced significant results.     

Air transport policy and its impacts on passenger traffic and tourist flows

This paper attempts to derive policy indices to quantify the restrictiveness of the aviation regimes in the Asia-Pacific region, and use the indices to establish the relationship between people movement and liberalisation in policy. Australia and Singapore have the most liberalised environment in this region. Evidence has been found that passenger traffic between city-pairs has been hampered by the restrictive air transport policies. Restrictions on the air transport sector also have a substantial negative impact on bilateral tourist flows. Further liberalisation in this sector could help build up a stronger tourism industry.     

Air transport demand and economic development in sub-Saharan Africa: Direction of causality

Air transport may be a key tool to advance economic development. However, it is uncertain whether air transport boosts economic development, or vice versa. Both views have theoretical and empirical support. In some countries and regions, air transport is important for initiating development, for example by attracting foreign direct investment or granting access to lifelines. Elsewhere, economic development drives air transport demand. Establishing the direction of causality for regions/countries segmented by income level may inform pragmatic policy. This study analyzes the causal relationship between air transport demand and economic development for six sub-Saharan African countries for the period 1981–2018. Vector error correction and vector autoregression models are employed to identify long- and short-run causalities. The results reveal heterogeneous, context-specific causal relationships. In the long-run, for South Africa, Nigeria and Kenya, the direction of causality runs from economic development to air transport demand; for Ethiopia, causality runs in the opposite direction, with increased demand for air transport promoting economic development; and for Senegal and Angola, the relationship is too weak to infer causal directions. Possible explanations for this heterogeneity include differences in per capita income, low-cost carriers' share of national aviation markets, the presence of large home-based airlines, and comparative geographical advantage as a natural hub.     

Exploring causality in trade and air passenger travel relationships: the case of Asia-Pacific, 1980–2010

This paper explores the potential of heterogeneous Granger analysis in transport geography research by applying this method to a specific case of the often complex and potentially reciprocal linkages between the deployment of transport infrastructures and spatial economic development: the linkages between rising intra-regional volumes of trade and air passenger traffic in Asia-Pacific. Although conceptual and empirical linkages between both indicators can be assumed based on previous research, relatively little is known about the actual causality. Using heterogeneous Time Series Cross Section Granger causality analysis for the period 1980–2010, we explore the presence of four ‘causality scenarios’ amongst different country-pairs: (1) there is no co-evolution, implying that both patterns develop independently (e.g. Japan–Australia); (2) there is ‘real’ co-evolution in that both patterns influence each other through feedback loops (e.g. South Korea–Philippines); (3) air passenger traffic is facilitated by trade (e.g., South Korea–Philippines); or (4) trade is facilitated by air passenger traffic (e.g. Australia–Malaysia). Some tentative interpretations of this heterogeneity are offered.     

An empirical analysis of Canadian international air policy: effects of dual carrier designation and partial liberalization

This paper assesses the impact on air traffic of Canada's policy of allowing two Canadian flag carriers (dual-designation) to operate in select Canadian international markets. The secondary objective is to assess the effect of Canada's partially liberalized bilateral air services agreements. Using panel data covering Canada's 33 bilateral markets over the 1982–1994 period, we find the following results: (a) dual designation/operation of Canadian carriers in a country-pair market increases total traffic volumes in the market as well as increases the combined passenger volume and market share of Canadian carriers, and (b) Canada's partially liberalized bilateral air services agreements have significantly increased air traffic in those country-pair markets.Two policy implications follow from this research. First, Air Canada's recent merger with Canadian Airlines is expected to have a significant negative impact on total traffic volumes as well as on Canadian carrier traffic volumes and market shares on the country-pair markets both Air Canada and Canadian served previously. Second, not only the US style full liberal bilaterals or open skies, but also partial liberalization of bilateral markets Canada adopted appears to generate consumer welfare benefits.     

Supporting the needs of special assistance (including PRM) passengers: An international survey of disabled air passenger rights legislation

Passengers who require special assistance at airports and on aircraft represent one of the fastest growing demographics for aviation worldwide. At some airports, annual growth in PRM (persons with reduced mobility) traffic is six times greater than the overall rate of passenger growth yet barriers to accessible air travel remain and disabled passengers continue to exhibit a lower propensity to fly than other travellers. In an attempt to aid disabled passengers’ accessibility to air travel, countries have introduced dedicated air passenger rights and consumer protection legislation which seeks to specifically address the needs of disabled travellers. These regulations typically state minimum service standards and levels of service provision that must be provided by air transport operators to enable disabled travellers to access air travel on an equal basis to other passengers. These legal interventions, however, have been developed on a country-by-country basis and this has created a lack of international regulatory alignment. This paper reports on the findings of an international survey of disabled air passenger rights legislation in 47 countries covering 20 aviation markets (the single market in the European Union and 19 other States). It identifies the differences in regulatory frameworks, highlights their implications for consumers and ultimately concludes by recommending the formation of more harmonised global policy making to better support the needs of special assistance passengers and facilitate their greater mobility by air.     

The development of air transportation in Nigeria

This paper examines the development of the Nigerian civil aviation industry since its inception in the 1920s, but particularly since 1980, examining the institutional framework, partial deregulation, infrastructural provision and passenger traffic. The current crisis in Nigeria's civil aviation industry, following the decline and near collapse of Nigeria Airways, is blamed on the absence of a coherent air transport policy, excessive bureaucracy, bad management and a failure to adhere to business principles. Full deregulation might be a solution.     

Evolution of regional inequality in the global shipping network

Global shipping is a backbone of the global economy, and as such, it evolves alongside the development of trade and the elaboration of commodity chains. This paper investigates the evolution of regional inequality in the global shipping network by analyzing the changing positions of world regions during the period from 2001 to 2012. This was a period of both prosperity and recession in maritime shipping. Using data on inter-regional flow connections, the positions of seventeen regions in the global shipping network are analyzed in terms of their traffic development, centrality, dominance and vulnerability. The East Asian, Northwest European and Europe Mediterranean regions have consistently held the highest positions, while East African and North African regions have held the lowest positions. By commanding the largest flows in the network, East Asia assumes a dominant position. The Australasian, North American West Coast, Northwest European and Southern African regions show an increasing dependency on East Asia. The analysis also identifies a few emerging regions that have had the highest growth rates in total traffic volume and connectivity for the studied period, namely South American North Coast, South American East Coast, West Africa, Southern Africa and West Asia. The empirical results of this paper supplement existing research on global shipping network evolution. One implication of the analysis is that the traffic growth of East Asia does not imply that, there is an equivalent improvement in its position in the global shipping network. The paper also shows that indicators from network analysis may be used to provide a more nuanced understanding of port-regional development than existing measures based solely on total traffic volume.     

Introduction to the special issue: Air transport in the Global South

Research on the development and impacts of air transport has hitherto focused mainly on developed countries in the Global North, and relatively little on less developed countries in the Global South. The seven papers of this Special Issue of the Journal of Transport Geography aim to address this imbalance and encourage further research on air transport development in the Global South. In recent years, the Global South has witnessed significant changes in air transport networks and policies, with implications for economic growth, spatial development and airline business models. This Special Issue explores some challenges to air transport development in the Global South for countries in Africa, South America, the Middle East and Asia, including links between air transport and economic development, the evolution and key drivers of air transport growth and the spatial distribution of passenger airline networks, and the development and impact of low-cost carriers. It also identifies opportunities for future research in this growing area.     

Analysing passenger network changes: The case of Hong Kong

Passenger throughput at Hong Kong International Airport (HKIA) has shown steady growth since its opening. Various aspects relating to HKIA have been studied in prior literature. This paper investigated changes in HKIA's passenger network for the period of 2001–2012 and used the gravity model to examine the key factors explaining its passenger traffic flows. The findings suggested that HKIA's passenger network has changed significantly and expanded to many new different destinations. Two regions (East Asia and Southeast Asia) were the most important markets for HKIA, and most key destinations connected by Hong Kong showed healthy growth. Nine factors could explain passenger traffic flows between Hong Kong and its key destinations: Hong Kong GDP per capita, GDP per capita of destinations connected by HKIA, distance, airport hub status of the destination airport, tourist destinations connected by HKIA, numbers of passenger airlines in service, bilateral trade flows, speaking a common language and having strong cultural/colonial links with Hong Kong, and the route presence of Cathay Pacific.     

The growing influence of low-cost carriers in Northeast Asia and its implications for a regional single aviation market

This paper provides an overview of the development of the low-cost carrier (LCC) sector in China, Japan, and South Korea. It is the first paper that documents LCC contributions to the passenger traffic and cheaper fares in Northeast Asia (NEA)'s intra-markets. We argue that a single aviation market can facilitate the growth of the LCC sector, which in turn will make a significant contribution to the NEA connectivity, mobility, and integration. In addition, with a single aviation market, NEA countries can adopt a proactive, unified approach in negotiating air transport agreements with the major aviation partners to maximize the interests of this region as a whole, which will further provide valuable growth opportunities for the LCCs.     

Making the connections between transport disadvantage and the social exclusion of low income populations in the Tshwane Region of South Africa

To date, the majority of studies which consider transport from a social exclusion perspective have been conducted in the context of the developed world where both income poverty and lack of transport are relative rather absolute states. In a unique departure from these previous studies, this paper explores the relationship between transport and social disadvantage in the development context, the key difference being that income poverty is absolute and where there is much lower access to both private and public transportation generally. Thus, it seeks to explore whether the concept of social exclusion remains valid, when it is the majority of the population that is experiencing transport and income poverty compared with the minority who do so in advanced economies.The paper is based on a scoping study for the Republic of South Africa Department of Transport (RSA DOT), which primarily involved focus group discussions with a range of socially deprived urban and peri-urban population groups living in the Tshwane region of South Africa. In a second departure from previous studies which consider transport and social disadvantage in the development context, the study takes a primarily urban focus. The rationale for this is that theoretically low income urban settlements do not suffer from the lack of transport infrastructure and motorised transport services in the way that more remote rural areas do. The policy issue is therefore less a question of addressing a deficit in supply and more one of addressing particular aspects of public transit service failure, which are more readily amenable to relatively low cost, manageable, small-scale national and local policy interventions.A primary aim for the study was to reinvigorate cross-government debate of these issues in the hope of breaking South African government’s long-standing and persistent policy inertia in the delivery of equitable and socially sustainable urban transport systems.     

Regional aviation and economic growth: cointegration and causality analysis in Australia

Air transport is a critical link to regional, rural and remote communities in Australia. Air services provide important economic and social benefits but very little research has been done on assessing the value of regional aviation. This research provides the first empirical evidence that there is short and long run causality between regional aviation and economic growth. The authors analysed 88 regional airports in Australia over a period of 1985–86 to 2010–11 to determine the catalytic impacts of regional air transport on regional economic growth. The analysis was conducted using annual data related to total airport passenger movements – for the level of airport activity, and real aggregate taxable income – to represent economic growth. A significant bi-directional relationship was established: airports have an impact on regional economic growth and the economy directly impacts regional air transport. The economic significance of regional air transport confirms the importance of the airport as infrastructure for regional councils and the need for them to maintain and develop local airports. Funding should be targeted at airports directly to support regional development.     

Greenhouse gas emissions from flying can offset the gain from reduced driving in dense urban areas

Numerous studies have illustrated how denser urban forms lead to smaller greenhouse gas (GHG) emissions from passenger transport. Many of these studies have excluded aviation since the association between urban structure and air travel is not as intuitive as it is the case of ground travel. However, several recent studies have concluded that air travel is a significant contributor to the GHGs from passenger transport. Furthermore, even air travel habits depend heavily on lifestyles and socio-economic factors that are related to the urban form. Here we analyse the interactions between urban structure and different transportation modes and their GHG impacts in Finland. The study utilises the data from the Finnish Transportation Agency’s passenger traffic survey from May 2010 to May 2011, which includes over 12 000 people and over 35 000 trips. The survey is based on one-day travel diaries and also includes additional data on long-distance trips from a longer period. Methodologically, the study takes a traveller’s perspective to assess the GHG emissions from passenger transport. We found that (1) air travel breaks the pattern where GHG emissions decrease with increasing density of urban structures, and (2) in the metropolitan region there is a clear trade-off between car-ownership and air travel in the middle income class. The main policy implication of our study is that air travel must be included in GHG assessments and mitigation strategies targeting travel behaviour. In dense urban regions, the emissions of air travel have the potential to offset the gain from reduced private driving.     

Maintaining competitiveness of aviation hub: Empirical evidence of visitors to China via Hong Kong by air transport

Prior studies have not extensively researched and explored the key determinants (aviation and tourism attributes) that could affect Hong Kong’s competitiveness as a transit hub for international visitors using Hong Kong as a stopover to Chinese cities when travelling by air. This study adds to that knowledge to empirically investigate Hong Kong’s eight major tourist source markets (Germany, India, Japan, Singapore, South Korea, Taiwan, the UK, and the US), and also provides an insight to policy-makers in Hong Kong to help them understand the factors that influence Hong Kong’s aviation hub competitiveness and tourism development. The findings of the study suggest that increased air transport capacity from foreign countries and Hong Kong to China, trade volumes between China and its trading partners, air transport costs, and the global financial crisis are the key factors affecting the number of visitors to China by air passing through Hong Kong as their preferred stopover. The policy implications of the findings are discussed.     

Domestic air passenger traffic and economic growth in China: Evidence from heterogeneous panel models

This paper applies recent panel methodology to examine the short-run dynamics, the long-run equilibrium relationships and the Granger causal relationship between economic growth and domestic air passenger traffic. It is based on the quarterly panel data of 29 provinces in China from the period of 2006Q1 to 2012Q3. Tests for panel unit roots, cointegration in heterogeneous panels and panel causality are employed in a bi-variate panel vector error correction model (PVECM), which is estimated by the system generalized moment method (SYS-GMM). The results show evidence of a long-run equilibrium relationship between economic growth and domestic air passenger traffic. Specifically, 1% increase in the air passenger traffic is found to lead to an increase of 0.943% in real gross domestic product (GDP). A long-run and strong bi-directional Granger causal relationship is found between these two series. It is also found that there is a short-run uni-directional Granger causality running from the domestic air passenger traffic to the economic growth.
