Airport efficiency in the dawn of privatization: The case of Greece

Until recently, all airports in Greece were owned and managed by the state; however, the recent economic crisis led the Greek government to privatize 14 regional airports. This paper evaluates the performance of the 38 Greek airports open to civil aviation just before the privatization was concluded. It also aims to highlight that the majority of airports with high efficiency were selected to be privatized. The analysis was performed applying Data Envelopment Analysis (DEA) and Malmquist Productivity Index (MPI) using 2011 and 2015 operational and financial data. Results showed that, despite the economic crisis, overall efficiency improved between 2011 and 2015, mainly due to the spectacular increase in incoming international passenger traffic. Changes in efficiency can be attributed by and large to exogenous factors such as operations of low-cost carriers and charter operators along with the seasonal operations of established carriers at individual airports. Findings confirm that the majority of high efficiency airports were offered to private investors.     

The effect of low-cost air transportation on the local economy: Evidence from Southern Italy

This paper investigates how the entry of low-cost carriers in Southern Italy has supported local and regional economic development in different ways: spreading the traffic demand during the year, increasing the rate of international tourism, generating new jobs and improving the income of the area. The evidence of traffic de-seasonality is quantified by an index, resulting in a decrease to all those airports specialized in low-cost services. Additionally, an assessment shows that the net impact driven by a low-cost route on the local economy is about €14.6 million per year.     

Spillover effects of the development constraints in London Heathrow Airport

In this article we assess the growth impact of London Heathrow’s development constraints on other airports in the UK. To test the relationship we use a two-stage methodology yielding an estimate of a congestion spillover effect. Our data are passenger traffic from 1990 to 2012 containing both intercontinental and European air traffic. For intercontinental air traffic, our results show high congestion spillover effect between Heathrow and Gatwick airports, and significant but lesser effect to Stansted airport. We also find significant congestion spillover effects from Heathrow to the spatially more distant Manchester and Birmingham airports, showing the extensive spatial impact of Heathrow’s development constraints. For European air traffic, controlling for low-cost air carrier growth, only two airports show significant congestion spillover effects: Gatwick and London City Airports. Illustrating that low-cost carriers do not operate from Heathrow, so its limitations cannot affect the predominant low-cost air traffic in other airports. The novel methodology we present in this paper can be applied to congestion research in general to assess regional and modal spills within networks.     

Observations of fundamental changes in the demand for aviation services

This paper addresses the seemingly inexorable decline in yield in the airline industry. The external shocks to the industry of the terrorist attacks of 9/11/2001, wars in Afghanistan and the Arabian Gulf and SARS all had downward impacts on the demand for air travel. However, these effects mask a more fundamental change in the demand for aviation services. The analysis uses published sources and a survey of 264 travellers to examine the fall in yields. The traffic mix of economy, business and first class passengers is shown to have changed over a 10 year period as proportionally more travellers choose to use economy class products. This combined with a fall in yield by a third in this cabin during the same period has lead to a significant fall in industrywide yields. Behavioural shifts in business travel and leisure demand are examined. Business travellers have switched from business class products as the difference between business class and leisure fares have increased significantly and as economy class and low-cost carrier products are increasingly viewed as acceptable for business traveller needs, particularly in short-haul markets. Leisure travel has increased as low-cost carriers have introduced low fares, generating new traffic and winning market share from scheduled and charter airline competitors alike.     

De-hubbing of airports and their recovery patterns

The paper analyzes cases of de-hubbing in air transport between 1997 and 2009. It initially addresses the conditions to be met for airports to be identified as de-hubbing cases. Second, it examines what happens after de-hubbing by clustering the cases into homogenous groups that show that, on average, airports that experienced de-hubbing did not recover their original traffic within five years and that de-hubbing is likely to be irreversible. When hub carriers were replaced at least partially by low-cost carriers, airports on average recovered faster. De-hubbing adversely affects the number of destinations served less severely than the seats offered by carriers.     

Measuring the LCC effect on charter airlines in the Spanish airport system

Using a robust transfer function model methodology, the present paper seeks to offer empirical evidence regarding the size and type of effects that low-cost carriers (LCCs) have had on traffic for charter carriers (CCs) in the Spanish airport system by geographic market. We show an unmistakable substitution relationship between CCs and LCCs in the latter's typical niche markets, national and European flights, while there is no reaction from the CCs in the segment of international flights outside the EU. Furthermore, substitution effects are smaller between CCs and LCCs on the domestic level than effects between LCCs and network carriers (NCs) and slightly larger on the European level. Lastly, CC traffic's different sensitivity to terrorist attacks, day of the week, air accidents and the economic crisis is also evident. CCs should therefore be considered an independent category that warrants individualized analyses.     

The impact of low cost carriers on Korean Island tourism

Given the mixed findings of extant research on the impact of low-cost carriers (hereafter LCC) on aviation markets (with some studies showing stimulation of new demand, other studies showing LCCs encroaching on the turf of full-service carriers), the emergence of LCCs in Korea raised an interesting question as to whether or not they actually contribute to overall growth in domestic air traffic. The literature has paid limited attention to this issue so far. Employing a multivariate regression analysis with monthly data from 2000 to 2009, the impact of LCCs on tourism demand to a popular destination in Korea, Jeju Island, is examined, focusing on two specific questions: Have LCCs generated new tourism demand and brought more tourism revenue into the island’s economy? Have LCCs mitigated tourism seasonality on the island? Controlling for the effects of a number of factors, results showed that LCCs have generated new demand in addition to existing tourist flows to the island. Korean LCCs accounted for 35% of total passengers in 2009, which indicates an average growth rate of 161.7% over the last 4 years, compared to a −0.3% growth rate for all full-service carriers in Korea. However, LCCs seem to have had little impact on reducing seasonal fluctuations in passenger traffic to Jeju Island. The findings of this study will be of interest to researchers, policy makers, and a variety of stakeholders in the tourism industry interested in the relationship between no-frills airlines and island economies.     

The impact of low-cost carriers on airport choice in the US: A case study of the Washington–Baltimore region

Previous research has shown that low-cost carriers (LCCs) may stimulate traffic at an airport by offering low fares. Using passenger survey data from the Washington–Baltimore region’s three airports, we find that the benefits of LCCs to airports extend beyond the traffic generated directly by the LCCs through their low fares. In addition, we find that the mere presence of an LCC at an airport can attract passengers, even to competing carriers. These “halo effects” from LCC presence increase the significance to airport managers of attracting LCCs in order to generate passenger demand.     

Mapping causalities of airline dynamics in long-haul air transport markets

The introduction of low-cost air transport services to short-haul routes has significantly shaped the structure of this market segment. Recent research investigates and discusses the transferability of the low-cost carrier business model to long-haul routes and identifies respective challenges such as lower cost advantages over the competing full-service network business model. Our paper complements the existing research with a review of airline dynamics in long-haul air transport markets and the subsequent development of a causal loop diagram of the transatlantic air transport market using systems thinking. The objective of this paper is to provide an overview of specific characteristics regarding airline operations in the transatlantic air transport market to investigate the market potential of long-haul low-cost carriers competing with full-service network carriers in this market. We implement these characteristics in a causal loop diagram which comprises the most important elements of and causalities within the long-haul air transport market that affect the development of these elements. These include the generation of transatlantic air transport demand, passenger choice, and airline ticket price and fleet development. The causal loop diagram serves as a framework for qualitative investigation of the market potential of long-haul low-cost services. The paper proves systems thinking to be a feasible approach to map causalities based on knowledge from scientific literature.     

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.     

Leisure travel in Europe and airline business models: A study of regional airports in Great Britain

Tourism and air transport are explicitly linked especially in the context of leisure traffic. This paper highlights this relationship by focusing on the impact of the three main airline business models (traditional scheduled, charter and low-cost) on regional airports using Britain as a case study. The panel data econometric results show that despite the current perception, low cost carriers are not the only ones to contribute significantly to airport aeronautical and non-aeronautical revenue. This observation has important policy implications and calls for transparency in airport subsidies as argued in the conclusion.     

Do low cost carriers have different corporate governance models?

In this paper, we investigate whether different business models in the same industry (passenger air transportation) lead to different corporate governance models. We found that low-cost carriers organise their boards differently from full service carriers to achieve lower costs and a faster decision-making process that is required by their business model. We also found that low-cost carriers and full service carriers solve their potential agency cost problems differently and that full service carriers have more board monitoring committees, and low-cost carriers have a closer coincidence of interests between shareholders and executive directors.     

Measurement of airlines’ capacity utilization and cost gap: Evidence from low-cost carriers

The aim of this paper is to evaluate the capacity utilization and cost gap between actual and global long-run minimum costs. Based on the data for thirteen low-cost carriers around the world for the year 2010, an input-oriented data envelopment analysis model is used to estimate the physical capacity utilization and cost gap between actual and global long-run minimum costs. The empirical results show that more than half of low-cost carriers should improve their capacity utilization, and all low-cost carriers should enhance their market efficiency and reduce their excess costs. Of the thirteen low-cost carriers, three should improve their technical efficiency, four should re-distribute the mix of variable inputs, all thirteen should pay lower prices for all variable inputs, and ten should enhance the utilization rate of their fixed factors.     

Economies of traffic density and scale in the integrated air cargo industry: The cost structures of FedEx Express and UPS Airlines

This paper examines the cost structures of the leading integrated air cargo carriers, FedEx Express and UPS Airlines. A total cost model is estimated for the two carriers using quarterly data on domestic operations and costs over a nine-year period (2003–2011). The estimated model indicates that the integrated industry exhibits increasing returns to traffic density and constant returns to scale. Accounting for carrier-specific differences in cost structure and network size, FedEx Express is found to be more cost-efficient than UPS Airlines. Looking at the carriers individually, UPS Airlines exhibits substantial economies of traffic density and constant returns to scale while FedEx Express' cost structure is characterized by weak economies of density and constant returns to scale. The combined effect of returns to density and returns to scale on the cost structures of integrated carriers is captured by economies of size. Both FedEx Express and UPS Airlines exhibit economies of size, indicating that carriers in the integrated industry can be more cost efficient by making appropriate adjustments to their network size as their output grows. Moreover, the relative cost-efficiencies of the carriers are reversed when their network-size differences are not controlled.     

Entry patterns of low-cost carriers in Hong Kong and implications to the regional market

This study aims to provide a better understanding of Asia's low-cost carriers (LCCs) by empirically analysing their route entry patterns in Hong Kong. Two alternative models have been tested, namely a standard probit model and a generalized least squares estimation. Consistent findings from the two models suggest that LCCs in Asia have a preference for large markets with big populations, high incomes and high traffic volume. On the other hand, the dominance of incumbent full service airlines (FSAs), fierce route competition and the lack of secondary airports are not critical to the growth of LCCs. However, government regulations and airport access are main impediment factors. Despite the adoption of long-distance low-cost models by the region's airlines, geographic distance still plays an important role in LCCs' entry decisions. For the growth of low-cost travel and associated benefits in the tourism industry and overall economy, it is important for governments in the region to liberalize aviation markets, provide sufficient airport capacity, and promote efficient allocation of airport slots.     

How the presence of low-cost carrier competition scheduling differentiation

This study explores the relation between airline market structure and schedule differentiation. Using a location theory framework applied to product differentiation over the time scale, the analysis relates the level of competition, and the presence of low-cost carriers in non-stop US markets to schedule clustering. As expected from theory, it is found that schedule clustering increases with competition, resulting in reduction in product differentiation. It is also found that this tendency is lower in the presence of low-cost carriers and when there is a strong hub effect where dominant hub airline own, rather than compete with their feeder subsidiaries.     

Determinants of airport cost flexibility in a context of economic recession

The recent economic downturn led to a significant contraction in the global demand for air travel and cargo. In spite of that, airports’ operating costs did not mirror the traffic trends and kept increasing during the same period, showing evident signs of lack of flexibility. With this background, this paper aims at identifying the drivers of airport cost flexibility in a context of economic recession. This is done by estimating a short-run stochastic cost frontier over a balanced pool database of 194 airports worldwide between 2007 and 2009. Using the total change in cost efficiency during the sample period as a proxy for cost flexibility, the impact of variables such as ownership, outsourcing, airline dominance, low-cost traffic, and revenue diversification is tested in a second-stage regression. Contrary to the existing literature, a higher level of outsourcing is shown to reduce cost flexibility. Results also indicate that low-cost traffic, diversification, and corporatization increase the airports’ ability to control costs. The negative impact of airline dominance suggests the need for more stringent regulations on slot allocation at congested airports in order to ensure optimal infrastructure usage.     

Legacy carriers fight back: Pricing and product differentiation in modern airline marketing

The adoption of the low-cost carrier business model has applied competitive pressure on established network or “legacy” carriers, by offering fares at prices that legacy carriers find it difficult to match and still cover their fixed costs. This paper reports how two medium-sized national airlines-Air New Zealand and Air Canada-have coped with the low-cost threat by, in effect, turning their fixed costs into profit centres. Features such as full regional networks, long-haul connections, frequent flyer programs, membership in global alliances, lounges and business class cabins can be bundled into products which can be marketed and sold profitably to business and even some leisure travellers, and which cannot be easily replicated by low-cost carriers. Although not panaceas, the innovations of Air New Zealand and Air Canada to the competition they face in their domestic and trans-border markets demonstrate the possibility of an effective legacy carrier response to the low-cost carrier business model.     

Price rivalry in airline markets: a study of a successful strategy of a network carrier against a low-cost carrier

In the post-liberalization period, competition has increased in airline markets. In this context, network carriers have two alternative strategies to compete with low-cost carriers. First, they may establish a low-cost subsidiary. Second, they may try to reduce costs using the main brand. This paper examines a successful strategy of the first type implemented by Iberia in the Spanish domestic market. Our analysis of data and the estimation of a pricing equation show that Iberia has been able to charge lower prices than rivals with its low-cost subsidiary. The pricing policy of the Spanish network carrier has been particularly aggressive on less dense routes and shorter routes.     

Perspectives on the Development of Low-cost Airlines in South-east Asia

Low-cost airlines are seen by some as one of the best things that have happened within contemporary travel. The clever business idea of offering significantly lower prices by taking out all the extras in a short-haul flight, along with innovative cost-cutting measures, was successful in the USA as early as 1973 when South-west Airlines flew her first low-cost flight. This paper asks whether this scenario has potential in Southeast Asia. According to many analysts, the environment in South-east Asia is simply not suitable for budget carriers. Governments are still very protective of their flag-carriers, there is a lack of cheap, secondary airports, South-east Asians are not wealthy enough to fly, and other cost-cutting measures like Internet distribution cannot easily be replicated. This paper argues that the opposite is true. There might not be 'open-skies' in South-east Asia, but the governments appear willing to nurture low-cost airlines to coexist with their flag-carriers. The number of airports that could serve as gateways for these airlines is more numerous than expected. The South-east Asian population is getting wealthy enough to fly and there also exists a significant market if the low-cost carriers can take advantage of it.
