Temporal configurations of European airline networks

The deregulation of the US domestic airline industry resulted in the reconfiguration of airline networks into hub-and-spoke systems. In contrast to the US airlines, airlines in Europe already operated spatially concentrated networks long before deregulation. This concentration at the national home-base was the outcome of bilateral traffic rights designated to the national carrier. With a few exemptions, however, most of these star-shaped networks were not coordinated in time. Transfer opportunities at most national airports only existed by accident. Only airports that were operated as gateways to Europe provided planned connectivity between intercontinental flights and European feeder services. The deregulation of the EU market stimulated a second phase of airline network restructuring. European airlines concentrated their networks by adopting or intensifying wave-system structures (‘banks’ to use the US term) in their flight schedules. This paper investigates these post-deregulation temporal concentrations in European aviation networks. The development and configuration of wave-system structures at European airline hubs is analyzed as well as the resulting transfer opportunities during the 1990s. It is found that a temporal concentration trend exists among European airlines with deregulation resulting in the adoption or intensification of wave-system structures by airlines. These wave-system structures, as well as overall traffic growth, have significantly stimulated the number of indirect hub connections. Airline hubs with wave-system structures generally perform better because of the increased indirect connectivity given the number of direct connections.     

Environmental sustainability,airport capacity and European air transport liberalization: irreconcilable goals?

The general aim of this paper is to discuss the apparently irreconcilable tensions that exist between policies for air transport liberalization in the European Union (EU), those directed at environmental sustainability, and the inadequacy of plans for additional airport capacity and modal shift to meet projected growth in air transport. The paper analyses the contradictory responses of the major stakeholders in the air transport industry to these problems, concentrating in particular on the environmentally incompatible strategies adopted by airlines in the competitive market-place. It concludes that environmentally driven capacity constraints at airports will effectively determine air transport's development within the EU, and that current laissez-faire attitudes of airlines and their regulators are unlikely to prevail as 'polluter pays' principles are more firmly implemented.     

EU/US Open Skies – Competition and change in the world aviation market: The implications for the Irish aviation market

The EU/US Open Skies agreement became operational on March 29th, 2008. The 23% increase in flights between Ireland and the US in 2008 under the agreement is the highest expected increase under the agreement and is almost three times greater than the expected overall increase in air travel between the EU and the US. Open Skies increases the number of routes between Ireland and the US by 3 to 10 and allows airlines to fly directly to and from Dublin without a compulsory stop at Shannon. There are very strong economic, investment, visitor, political and ethnic ties between Ireland and the US and air travel between the countries per head of population in Ireland is 5.6 times greater than the EU average. The benefits from Open Skies include lower fares, new routes and direct services reducing the need to backtrack over European hubs, in addition to the abolition of the requirement to stopover at Shannon.     

Airline competition on the route between Amsterdam and London

Although liberalization in European air transport business was formally completed with the implementation of the third package of the EU, today the free market effects of abandoning the bilateral system are not yet very manifest. The experiences in the United States indicate that it can last for over a decade before more or less stable competitive positions are set according to liberalized market conditions. The Amsterdam-London route was among the first routes which was liberalized on a bilateral basis. The development of airline competition on this route gives a rather good insight in what might be expected on other European routes the following years. In the ATRG paper, emphasis is laid upon the following competition characteristics: the number of airlines serving the London routes; the frequency offered by these airlines; the average aircraft size; the air fares charged. Special attention is paid to the relative attractiveness of the various airports in the Londen Area. Also the entrance of start-up carriers that offer no frills, no thrills services is covered.     

Including aviation emissions in the EU ETS: Much ado about nothing? A review

The European Community, motivated by the rapid growth of the aviation industry and related impacts on climate change, has decided to include aviation in the European Emissions Trading Scheme (EU ETS). Mitigation policies such as the EU ETS are considered to be necessary in order to change travel behaviour and induce operational and technological changes in the aviation industry that will result in lower environmental impacts. This paper reviews the available impact assessments of the proposed emissions trading scheme for airlines published between 2005 and 2009. It analyses the methods used and finds that the models used are often over-simplified, omitting important variables or that the reliability and robustness of the modelling results are reduced by linking models that are based on different assumptions. The paper also summarises the possible environmental (CO₂ emissions) and economic (air fares, demand for airline services, supply of airline services, competitiveness, GDP, carbon price) impacts in the studies reviewed for the year 2020. Overall, the effects are found to be small: for example, CO₂ emissions are expected to decline by a maximum of 3.8% and the maximum impact on GDP in the EU was found to be ?0.002%. The reasons for these insignificant impacts are analysed in this paper; it is also found that there are some positive aspects of including aviation in the EU ETS.     

Competition and cooperation between high-speed rail and air transportation services in Europe

New high-speed rail (HSR) lines may have an enormous influence on the provision of air services. The attention has been devoted to competition between both transportation modes but in some cases HSR services may also have an intermodal complementary role with air transportation. By taking a supply oriented empirical analysis, we study the impact of HSR on air service frequencies and seats offered by airlines in large European countries. We emphasize the distinction between routes with and without a hub airport as an endpoint and we also examine the influence of the location of the HSR station. We generally find direct competition between HSR and airlines, but we also provide some evidence that HSR can provide feeding services to long haul air services in hub airports, particularly in hub airports with HRS stations.     

Including aviation in the European emissions trading scheme: Impacts on the industry,CO2 emissions and macroeconomic activity in the EU

In July 2008, motivated by the expected high growth of aviation and the related impacts on climate change, the European Parliament adopted a directive to include airlines in the European Emissions Trading Scheme. This paper discusses possible impacts of this inclusion on the aviation industry in terms of CO₂ emissions and the macroeconomic activity in the EU. The analysis uses the Energy–Environment–Economy Model for Europe, a dynamic simulation model to investigate impacts of the European Emissions Trading Scheme on air transport. The impacts on air transport output and the macroeconomic effects are estimated to be small. This was robust to varying the carbon price. However, air transport CO₂ emissions were expected to decrease by up to 7.4%, which is more than that estimated previously and stems mainly from the supply-side reaction of the industry.     

Reinterpreting the role of primary and secondary airports in low-cost carrier expansion in Europe

This paper discusses the long-term effects of low-cost carrier (LCC) presence at European airports and identifies the airports that have benefited the most from LCC consolidation since 2001. The research uses ‘LCC Market Share’, in terms of seats, to measure the relative importance of LCCs within each airport; and introduces ‘EU LCA Rank’ as a normalised metric of the capacity share of every airport in the European low-cost segment. It evaluates the trends between 2001 and 2019 in all airports in Europe using OAG supply information (seats by carrier). Results show two different phases of LCC rise in Europe, 2001 to 2008 and 2009 to 2019, marked by the effects of the financial crisis of the Great Recession. The analysis highlights the role that LCCs have played in boosting the growth of both primary and secondary airports. Indeed, despite the fact that LCCs have put many smaller airports on the European map, during the second phase of the period of analysis growth has been more significant for major airports and for a few airports that were keen to support the earliest development of LCCs. In that sense, this paper contributes to a better understanding of the historical and contemporary dynamics in European LCCs choice of airports and, in particular, the long-term effects that this disruptive business model have had for airports. This is increasingly important in the context of a potential recovery path from the effects of the response to the Covid-19 pandemic. This paper also attempts to settle academic discussions that attach LCC development to secondary/regional airports disregarding the wide range of strategies used by airlines and airports.     

Exploring characteristics of passengers using traditional and low-cost airlines: A case study of Belgrade Airport

Low cost carriers entered the Serbian air travel market after Serbia joined the European Common Aviation Area (ECAA) in 2006, prompting the development of healthy competition among airlines and resulting in significant traffic increase at Belgrade Airport. The aim of this paper is to examine the characteristics of passengers traveling on low-cost carriers (LCC) in comparison with those traveling on traditional airlines by using cluster analysis, and to provide practical implications to airport management in tailoring their strategies to meet growing demand. A comprehensive passenger survey was recently conducted at Belgrade Airport on the routes where competition between traditional and LCC carrier exists. The results reveal that emigrants, primarily encouraged by favorable fares, constitute a substantial portion of LCC passengers. Affordable service offered by LCC has also been a positive stimulus for emigrants, who purchase tickets for their friends and relatives to visit them in their host countries. On the other hand, passengers using traditional airlines could be generally classified into two segments, those who fly on business and those who fly for leisure purposes, and each had specific needs when choosing their airline.     

EU network carriers,low cost carriers and consumer behaviour: A Delphi study of future trends

This paper uses a Delphi panel of 26 air transport experts to forecast the structure of air transport in the EU in 2015 in respect of network carriers, low cost airlines and passenger behaviour. Secondary research was used to construct a number of scenarios about the future structure and strategy of EU network and low cost airlines and also traveller behaviour. Consensus of opinions was sought amongst the panel in a two-round process. The consensus opinion of the Delphi experts was that; network carrier consolidation will reduce EU players to less than five, there will be only two or three large low cost carriers, Business Class products will disappear on short hauls, and leisure travellers will take an increasing number of multiple short-duration holidays.     

US open skies agreements and unlevel playing fields

We examine the relationship between ‘Open Skies’ agreements (OSAs) signed between the USA and various countries or regions and the existence of subsidies and other forms of protection that advantage one nation's airlines over those of co-signatories to an OSA. We argue that under an oligopoly market structure, strategic competition brought about by OSAs creates incentives to subsidize and/or protect domestic airlines. Such incentives are maintained or amplified by political lobbying efforts that bias civil aviation policies towards producer interests over wider measures of economic welfare. We report on financial aid and policies which have advantaged US airlines during the OSA period and which suggest that unlevel playing fields have been made more unlevel during the era of OSAs.     

How to regulate aviation's full climate impact as intended by the EU council from 2020 onwards

The EU Council intends to regulate air transport's full climate impact (i. e., CO₂ and NO_x, H₂O, SO_x, aerosols, contrails and contrail cirrus). A likely approach is the inclusion of all climate relevant species from aviation in the European Emissions Trading Scheme. We provide a proposal for this practice and analyze the economic impacts. Modelling results indicate that the cost effects of the EU-ETS addressing CO₂ and non-CO₂ emissions will be much larger than under the current scheme. This is because under the new approach, all climate relevant species are regulated and not just CO₂. The cost effects also depend on the length and altitude of the flight. Both have consequences for the competitive environment of the airlines under the scheme. Especially the full service network carriers will have to bear a competitive disadvantage compared to airlines offering just short- and medium-haul services. Remarkably, some cost effects are in opposition to the corresponding results for an ETS for the regulation of CO₂ alone.

Airport–airline interaction: the impact of low-cost carriers on two European airports

This paper uses case studies to look at the impact of low-cost airlines on two European airports. Low-cost airlines continue to exert an influence in air transport markets and small airports face pressures to compete for their business. The low-cost model motivates airlines to negotiate contracts that significantly reduce aeronautical revenues, leaving airports to compensate by seeking commercial revenues from the increase in passengers. This has consequences for the airports, their passengers and the relationship between the airport and its existing operators. It is found that it is important for airport management to see both passengers and airlines as customers and to understand the resultant revenue streams, before negotiating preferential contracts with low-cost carriers.     

European mobility cultures: A survey-based cluster analysis across 28 European countries

More targeted European policies promoting green travel patterns require better knowledge on differing mobility cultures across European regions. As a basis for this, we clustered the EU population into eight mobility styles based on Eurobarometer data. The mobility styles – including, for example, “green cyclists” and “convenience drivers” – differed not only in their travel-related variables but also in their socio-economic background, IT-affinity, and life satisfaction, with green cyclist showing the highest life satisfaction and two car-oriented styles having the highest socio-economic resources. In a second step, the 28 EU member countries were clustered into six country clusters based on their representation of mobility styles. The country clusters indicate the existence of considerably different mobility cultures across the EU. Sub-regions can be identified that have highly different positions on the path towards sustainable mobility and therefore different requirements towards European platforms and support measures, e.g. for ‘Sustainable Urban Mobility Plans’. The country clusters can provide a starting point for future communication and targeting of European efforts in sustainable mobility.     

Cost and revenue synergies in airline mergers – Examining geographical differences

Deregulation, privatization and shifting demand patterns in the airline industry, combined with the emergence of low-cost airlines and rising fuel prices have increased the competitive pressure on legacy airlines. Since alliances do not deliver sufficient benefits to counterbalance these trends, many airlines have engaged in mergers to seek for additional cost and revenue synergies. An extent body of literature investigates the synergy potential in mergers and alliances, but there is no study on how synergies differ among mergers and what potential influence factors cause these differences. This paper aims at explaining differences in synergy estimates and realized synergies in recent airline mergers and places a special focus on geographical influence factors.The research methodology uses a comparative case study comprising six large airline mergers between 2003 and 2012 from Europe, North America and Latin America. After analyzing the cases individually, the pre-merger situation of the merging airlines, the synergy estimates and the realized synergies of the cases were compared.The results show considerable geographical differences in pre-merger cost structures, synergy estimates, and synergy realization. The European mergers present lower synergy estimates but also lower integration costs than mergers in the Americas. Whereas European airlines estimate cost synergies higher than revenue synergies, both North and Latin American airlines expect more revenue synergies than cost synergies from airline mergers. Only one merger showed superior post-merger profitability which indicates that the achieved synergies in the broad majority of the cases are insignificant.     

A productivity comparison of the world's major airlines

This paper measures and compares productivity and unit cost of the world's 23 major airlines using yearly panel data (1986–1993). An extensive effort was expended to put together a reliable database. These data are then used to accomplish the following: first, unit cost per unit of aggregate output is measured and compared. The effect of input price changes on the unit costs are also examined. Second, the ‘gross’ Total Factor Productivity (TFP) is measured and compared. In order to compare true productive efficiency across airlines and over time, a ‘residual’ TFP index is computed after removing effects of the variables beyond managerial control such as average stage length and composition of outputs. Log-linear TFP level, and TFP growth rate regressions are used to accomplish this task. Our results show that:

1. (a) during the sample period (1986–1993), the major European carriers and the carriers in newly industrialized countries in Asia have achieved significantly higher productivity growth than their North American counterparts;

2. (b) as a result, the productivity gap between North American and other carriers have diminished significantly;

3. (c) however, on average, the North American carriers still enjoy higher productive efficiency than the carriers in Asian NICs and European carriers, but the gap is closing very rapidly; and

4. (d) it is observed that, over time, the productive efficiency of carriers competing in the same markets tends to converge.

Finally, Asian NIC carriers clearly enjoy unit cost advantages over other major carriers. Our results show that European aviation liberalization which began in 1987 appears to have produced substantial productivity gains.     

The impact on traffic,market shares and concentration of airline alliances on selected European—US routes

This paper examines the impact of airline alliances on traffic of the constituent airlines using an analysis of US Bureau of Transportation Statistics T-100 International Market Data on a monthly basis for five routes to the US from European hubs. The European hubs are Frankfurt and Paris. The period covered is January 1990–December 2003; a sufficiently lengthy period to enable the derivation of good time-series models before the ‘intervention’ of alliance formation and development. The alliances focussed on are Air France and Delta, part of the SkyTeam Alliance and Lufthansa and United Airlines, part of the Star Alliance. It is possible to distinguish code sharing agreements and then the subsequent immunity from US antitrust legislation. It is also possible to suggest some conclusions on the differences in alliance development in the more liberal open skies environments adopted by many European countries with the more traditional, stricter regulated bilaterals that exist in others such as the UK. Competition is examined using the Hirschman-Herfindahl Index so as to throw light on the impact of alliances on market concentration by route.     

Will the EU-ETS instigate airline network reconfigurations?

Based on the proposal of the European Commission on including the aviation sector into the European Emission Trading Scheme, a route-based analysis is conducted simulating cost and demand implications for selected airlines. For a scenario of €20/tons CO₂, results indicate that the EU-ETS CO₂-based cost increases for the airlines are between €9 and €27 per route and therefore, as an individual factor, are not high enough to instigate major route reconfigurations among European airlines.     

New Europe,new low-cost air services

Only a few years ago European low-cost service was almost exclusively focused on Western Europe. However, the enlargement of the European Union to East Central Europe has brought with it an expansion of the liberalised air space, thereby offering new opportunities for service to Community airlines. Low-cost air service has since diversified in favour of new west–east air links that represent almost 60% new routes that have opened up between Western and East Central Europe. The western low-cost airlines dominate the market rather than Eastern European ones. The new west–east routes reflect new forms of mobility: post-migration flows from the east by those who have gone to work in Western Europe, new tourist practices and undoubtedly new types of business as well.
