This chapter reviews the key results obtained in previous studies of airline mergers. It is found that the effect of mergers on airfares is dependent on the network configurations of merging airlines. Fare increases are frequently observed on overlapped routes. However, if the networks of two merging airlines are complementary, the expanded network after the merger leads to cost savings, increase in travel options, and improvement in service quality. Therefore, in a deregulated market, with few entry barriers, relaxing merger regulations is likely to improve welfare. However, most welfare evaluations do not incorporate quality changes or dynamic competition effects. Empirical investigations are primarily ex post analysis of mergers that have already passed antitrust reviews. The relationship between market concentration and welfare might be nonlinear and market specific. Therefore, airline mergers and alliances should be reviewed case by case. Methodological improvements are needed in future studies to control for the effects of complicating factors inherent in ex post evaluations.

In this chapter, we will review the history, deregulation, policy reforms, and airline consolidations and mergers of the Chinese airline industry. The measurement of airline competition in China’s domestic market will also be discussed. Although air deregulation is still ongoing, the Chinese airline industry has become a market-driven business subject to some mild regulations. Then, we will review the impressive development of the high-speed rail (HSR) network in China and its effects on the domestic civil aviation market. In general, previous studies have found that the introduction of HSR services has a significant negative impact on airfare and air travel demand in China. The rapidly expanding network of HSR has important policy implications for Chinese airlines.

This chapter reviews the effects of air transport liberalization, and investigates the roles played by airport-airline vertical arrangements in liberalizing markets. Our investigation concludes that liberalization has led to substantial economic and traffic growth. Such positive outcomes are mainly due to increased competition and efficiency gains in the airline industry, and positive externalities to the overall economy. Liberalization allows airlines to optimize their networks, and thus may introduce substantial demand and financial uncertainty to airports. Vertical arrangements between airlines and airports may offer a wide range of benefits to the parties involved, yet such arrangements could also lead to airline entry barriers which reduce the effects of liberalization. Three approaches have been developed to model the effects of liberalization in complex market conditions, which include the analytical, econometric and computational network methods. These approaches should be selectively utilized in policy studies on liberalization.

Alliances between companies are an example of a collaborative strategy adopted in anticipation of highly uncertain markets. Since 1980, the commercial airline industry has been affected by a progressive liberalization worldwide. In this historical context, most airlines reacted with defensive movements in the face of high competition. In the case of airlines in the Spanish market, one of the largest in the world due to the weight of the tourism sector in its economy, airlines responded in various ways to the intensification of competition. Iberia, the main Spanish airline, established different defensive alliance policies. In the 1980s, alliances were mainly collaborative. Since 1998, airline alliances have become coopetitive in nature, as was the case with the creation of One World group (American Airlines, British Airways, Cathay Pacific, Qantas and Iberia). The partners began to interact in a more horizontal way, maintaining various agreements (code-sharing, handling, schedule coordination, shared sales, fleet maintenance) without renouncing their independence in the face of global competition. Iberia has subsequently modified the composition of its portfolio to move towards a more vertical collaboration with the integration into the IAG Group (Iberia, British Airways, Air Lingus and Vueling). This second phase is a quest to increase market power with deep changes in the nature of its alliances while maintaining coopetitive alliances.

With significant changes in the aviation industry, various airport–airline arrangements have been formed to achieve alternative objectives. However, no consensus has been reached on such arrangements’ economic effects and the associated optimal public policy. This chapter aims to provide an interpretive review of the common types of airport–airline arrangements, the different modeling approaches used and key conclusions reached by recent studies. Our review suggests that airport–airline arrangements can take diverse forms and have been widely used in the industry. They may allow the airport and its airlines to internalize demand externality, increase traffic volume, reduce airport investment risks and costs, promote capacity investment, enhance service quality, or simply are a response to the competition from other airport–airline chains. On the other hand, such vertical arrangements, especially for those exclusively between airports and selected airlines, could lead to collusive outcomes at the expenses of non-participating organizations. The effects of such arrangements are also significantly influenced by the contract type, market structure and bargaining power between the airport and airline sectors. While case by case investigations are often needed for important economic decisions, we recommend policy-makers to promote competition in the airline and airport segments whenever possible, and demand more transparency or regulatory reporting of such arrangements. Policy debates and economic studies should be carried out first, before intrusive regulations are introduced.

European air transport policy, emerged through the confluence of case law and legislation, in four broad areas: liberalization, safety and security, greening, and the external policy. Following the implementation of the single market for air transport, policy shifted to liberalizing and regulating associated services and in recent years to greening, the external aviation policy, and safety and security. Inclusion of air transport in the Environmental Trading Scheme of the European Union exemplifies the European Commission’s proactive stand on bringing the industry in line with emission reduction trajectories of other industries. However, the bid to include flights to third countries in the trading scheme pushed the EU into a controversial position, causing the Commission to halt implementation and to give ICAO time to seek a global multilateral agreement. The chapter also discusses how the nationality clauses in air services agreements breached the Treaty of Rome, and a court ruling to that effect enabled the EC to extend EU liberalization policies beyond the European Union, resulting in the Common Aviation Area with EU fringe countries and the Open Aviation Area with the USA. Another important area of progress was aviation safety, where the EU region is unsurpassed in the world, yet the Commission has pushed the boundary even further, by establishing the European Safety Agency to oversee the European Aviation Safety Management System. Another important area of regulatory development was aviation security, a major focus after the woeful events in 2001, but increasingly under industry scrutiny on costs and effectiveness. The chapter concludes by arguing that in the coming decade, the EU will strive to strengthen its position as a global countervailing power, symbolized in air transport by a leadership position in environmental policy and international market liberalization, exemplified in the EU’s external aviation policy.

This chapter reviews three main issues in the interactions between air transport and high-speed rail (HSR) in China, namely the interaction between low-cost carriers (LCCs) and HSR, HSR speed effect on airlines, and airline–HSR integration. Studies on these three aspects of airline–HSR interactions have yet been well reviewed, and our chapter aims to fill in this gap. In this chapter, we comprehensively survey literature on the topics, especially studies on Chinese markets that have recently witnessed major HSR developments (and have planned further large-scale HSR expansion in the coming years). Our review shows that, first, compared to full-service carriers, LCCs face fiercer competition from HSR. However, the expansion of HSR network in China can be better coordinated with LCC development. Second, HSR speed exerts two countervailing effects on airline demand and price (the “travel-time” effect and “safety” effect, respectively). Specifically, an HSR speed reduction can have a positive effect on airlines due to longer HSR travel time, but a negative effect on airlines due to improved perception on HSR safety. Third, airline–HSR integration can be implemented through cooperation between airlines and HSR operators and through co-location of airports and HSR stations and can have important implications for intermodal transport and social welfare.

This chapter uses airline data on fares, traffic, and flight characteristics to estimate a series of fare equations for international flights. The results are used to examine the role of international competition as a determinant of fares along international flights originating or departing from the United States. Findings suggest that actual and potential competition are important determinants of international airfares. We interpret these results as indicating that pricing behavior along US–international routes is consistent with the theory of imperfect contestability.

Looks at the world airline industry, from 1978 to 1998, from a strategy perspective. Traces the strategic developments and the strategy responses of the key airline players that have had a profound impact on the shape and direction of the industry. These include the deregulation of the industry, the nature and extent of competition, the emergence of brand/differentiation based competition, and airline alliance developments, strategies and their implications. Also provides a glimpse of what the future will hold for the world airline industry, including the prospects of increased global market concentration and the emergence of mega consortia, comprising lead airlines from key regions of the world, on the global stage. These global consortia, which will marginalise other players, will also compete against each other on the basis of branding/differentiation.

Following deregulation, the airline industry has dramatically changed. In addition to numerous mergers and bankruptcies, the industry has also seen an influx of small, “low-cost” carriers who offer differentiated competition to the traditional legacy carriers. These low-cost carriers traditionally avoided the hub-and-spoke networks of legacy carriers, offering point-to-point service often on adjacent routes. However, events of the past 10–15 years, including the terrorist attacks of 9/11, rising fuel prices, and economic recessions, have led to a shift in the operations of these airlines. The legacy carriers have unbundled many of their services, most notably through baggage fees, seeking to improve efficiency. Low-cost carriers have expanded services into major airports and have shifted to more direct route level competition with the legacy carriers as they use their cost efficiency advantages to their advantage. In this chapter, we examine airport and route choice decision to serve by legacy and low-cost carriers over time. Our descriptive and econometric models point to convergence of operations in terms of the airports and routes that low-cost and legacy carriers serve, with the implication that the current competitive atmosphere improves efficiency as the distinctions between legacy and low-cost carriers have become less obvious.
