Mitigation of airspace congestion impact on airline networks

In recent years European airspace has become increasingly congested and airlines can now observe that en-route capacity constraints are the fastest growing source of flight delays. In 2010 this source of delay accounted for 19% of all flight delays in Europe and has been increasing with an average yearly rate of 17% from 2005 to 2010. This paper suggests and evaluates an approach to how disruption management can be combined with flight planning in order to create more proactive handling of the kind of disruptions, which are caused by congested airspace. The approach is evaluated using data from a medium size European carrier and estimates a lower bound saving of several million USD.     

The impact of US–EU “Open Skies” agreement on airline market structures and airline networks

The gradual liberalization of international air transport has largely benefited the traveling public. Progress since the development of concepts such as “Open Skies” in the late 1970s as an alternative to the restrictive bilateral air service agreements that had effectively controlled most international air transport since the mid-1940s has been uneven and spasmodic. The recent move to open the North Atlantic more fully to competition has proved a particularly challenging task, and the agreement between the US and the European Union is still both partial and conditional. This paper offers an overview of the economics of the situation and provides insights into the reasons why it has developed in the way it has, the outcomes that we may expect from it, and some consideration of the wider, non-commercial, impacts that it may have.     

The impact of hubbing concentration on flight delays within airline networks: An empirical analysis of the US domestic market

This paper explores the relationship between hubbing activities and flight delays in the United States from an airline-specific network perspective. Airline hubbing is measured with the Hubbing Concentration Index. We estimate the impact of hubbing behavior on delays, using three measures of delay, two based on delay against schedule, and the third based on buffer-corrected excess travel times. A significant (and positive) influence of hubbing concentration can only be found for the latter delay indicator. We conclude that airlines use buffer times to mitigate passenger-perceived delays against schedule that would, without buffers, arise from more complex network operations.     

The impact of airline financial distress on US air fares: A contingency approach

This article investigates to what extent an airline’s financial distress impacts its pricing behavior. While prior research suggests that, on average, distressed airlines sell at lower fares, it is hypothesized that the magnitude of this effect may depend on certain firm and market specific contingencies. A large-scale empirical analysis using panel data from the US airline industry is conducted. The results indicate that firm financial distress and air fares are generally negatively related. It is further shown that the magnitude of the effect of distress on fares decreases with the magnitude of operating costs and firm’s market shares and increases with firm size and the level of market concentration. Implications for policy makers and managers are discussed.     

The impact of airline internal branding on work outcomes using job satisfaction as a mediator

Within the context of the airline industry, this study offers an integrated approach measuring the effects of internal brand communication, brand-centered training, transformational leadership, brand ideology, and internal brand communities on job satisfaction and work outcomes. It further explores the role of job satisfaction as a mediator between internal branding and work outcomes. Following an analysis of 485 responses, we find that leadership, ideology, and communities positively influence job satisfaction, which in turn affects intention-to-stay, team performance, and brand commitment. Job satisfaction is also found to mediate the relationships between internal branding (i.e., transformational leadership, brand ideology, and internal brand communities) and work outcomes. These findings highlight that appropriate branding strategies can enhance airline development through employee satisfaction.     

The strategic impact of airline group diversification: The cases of Emirates and Lufthansa

The airline industry is a diverse sector, requiring the support of a varied range of ancillary businesses such as maintenance, catering and travel agencies to carry out its activities. Many of these supporting businesses demonstrate the potential to drive wider profit margins despite generating lower revenues than the airlines themselves, making them attractive investment opportunities in a sector prone to volatile and often lacklustre trading. This study investigates two of the largest diversified airline groups, Germany's Lufthansa Group and Dubai's Emirates Group, each adopting a distinct approach towards diversification that may serve as a model for airline groups worldwide. The areas investigated were Cargo, Maintenance, Catering and Travel Services. The research found that whilst diversification may not always present the most attractive option financially, strategic factors can often outweigh such concerns. Business units studied were found to have variable prospects; particularly in the case of Catering, a sector on the rise – versus in-house Maintenance, which for airlines, is likely to see decline. The pursuit of third party revenue streams to offset weak internal trading and growth in competencies were found to be the key drivers of success. Interplay between segments was also apparent, showing that a well-organised diversification strategy can achieve robust cross-functional benefits and deliver significant value to the parent organisation.     

The impact of airline lease agreements on the financial performance of US hub airports

This paper employs benchmarking analysis to examine the financial implications of the different types of airline lease agreements used by US airports. Five key financial performance areas relating to cost effectiveness, revenue generation, commercial performance, financial profitability and capital investment are analysed using financial data from 2011/12 for 23 of the 29 large-hub airports. The results show that compensatory airports are the most financially efficient, particularly in terms of debt efficiency, revenue generation and profitability while the vertical airport airline relationship that is common at residual airports delivers higher levels of commercial performance and cost efficiency.     

The impact of airport parking fees on the tourist's airport/airline choice behavior

This paper analyzes the airport/airline choice behavior of tourists for Saxony/Germany. We employ flexible parametric choice methods (mixed logit) in order to test the effect of standard attributes on the choice probability. In addition we extend existing literature with the introduction of parking charges in the choice experiment. Our results show a significant and negative impact of parking charges on airport choice probability. Thus, we can compute high elasticities of parking charges for tourists. These results suggest, that airport managers have in form of parking policies a powerful policy instrument as they can directly affect the size of the airport catchment area.     

Low-cost carriers versus full service carriers in ASEAN: The impact of liberalization policy on competition

This study analyses the ASEAN Single Aviation Market (ASAM) policy to be introduced by the end of 2015. We conduct a scenario study to estimate the impact of low-cost carrier (LCC) network expansion under liberalized air transport policies in the ASEAN region. Establishing joint ventures is a possible way for foreign carriers to expand the network in this region, even after starting ASAM. This is unique as joint ventures are not only subsidiaries of the full-service carriers, as is the case in the United States and Europe. We also apply a quantitative air transport market model to estimate the policy impact of the entry of new LCCs on routes from three ASEAN hub airports to Manila airport, which covers the impact on the whole network. The model produces several significant results, including that the entry of one LCC on one route may affect the fare, frequency, and profitability of related competitive routes for the entire network.     

The impact of COVID-19 on airline passenger travel behavior: An exploratory analysis on the Chinese aviation market

China was the first airline market in the world to be hit hard by the COVID-19 pandemic. It has been gradually recovering as the pandemic is largely contained domestically. However, with the global pandemic spread and great uncertainty, there has been a remarkable change in airline passengers’ travel behavior. This paper collected air passenger-level data from TravelSky in the Chinese market. In addition to the analyses on aggregate passenger flow patterns, this paper explores changes in airline passenger travel behavior, such as ticket booking time, age distribution of passengers, refunds and ticket changes, and passenger arrival time at airports. This is one of the first studies to focus on micro-level changes in airline passenger travel behavior by using objective passenger-level data. The pandemic-induced psychological changes in air travelers are explored, providing useful managerial and policymaking implications for the normalization of the pandemic and the recovery of the airline market in the post-pandemic era.     

The impact of airline alliance terminal co-location on airport operations and terminal development

The notion of co-locating alliance carriers to their designated terminals in airports has gained significant interest in recent years. While benefits on the part of airlines are made clear by existing literature on alliance-hubbing, the tangible benefits to airport operators are less clear due to a lack of studies in the literature. This paper considers existing cases of London Heathrow, Paris Charles de Gaulle and Tokyo Narita Airport, and applies their operational practices to a medium-sized airport in Asia Pacific to evaluate the universal applicability of alliance member co-location. Although some operational and financial improvements are observed, the paper concludes that implementation of this concept should not be done through a one-size-fits-all approach.     

Estimating the impact of airport privatization on airline demand: A regression-based event study

This paper develops an empirical model of passenger demand for routes of airports subject to either imminent or recent privatization. We investigate whether the privatization process produces a sequential impact over traffic. By employing a regression-based event methodology and controlling for fixed effects, price endogeneity and sample selection, we perform an econometric analysis of pre-privatization and post-privatization dynamic patterns of demand to infer the demand consequences of the major change in airport governance. We examine recent Brazilian airport privatization experience as a case. The main results suggest that privatization produced an overall increase in airline demand and that the airport notably recognized with the greatest demand potential and with the largest market penetration of a fast-growing low cost newcomer had the highest estimated ceteris paribus effect of privatization on demand.     

A combined MCDM model based on DEMATEL and ANP for the selection of airline service quality improvement criteria: A study based on the Taiwanese airline industry

The aim of this study is to select airline service quality improvement criteria for the Taiwanese airline industry. Numerous factors such as low railway prices, the development of high-speed rail, increases in petroleum prices, increases in foreign airline competition, and the recent economic depression have led many airlines in Taiwan to encounter financial difficulties and even closure. Researchers have begun to identify critical service quality improvement criteria with the goal of increasing the competitive advantages of airlines. Most of the selected criteria, however, suffer from a major technical problem: all of the measurement dimensions are independent, leading to inadequate criteria for measuring service quality. Our calculations consider the interrelationships and effects among the evaluation dimensions and criteria to precisely rank and select criteria. The value of this study is that it provides airlines with a direction for measuring and improving their service quality with the goal of developing sustained competitive advantage over the long term.     

Quantifying the impact of the COVID-19 pandemic on US airline stock prices

This paper uses data at the trading day frequency and the method of local projections to quantify the dynamic responses of U.S. airline stock prices to a COVID-19 shock. We show that airline stock prices decline immediately by 0.1 percentage point in response to a 1% COVID-19 shock. In addition, the effect of the shock persists beyond the day on which it occurs, with most airline stock prices falling by as much as 0.6 percentage points after fifteen days. This negative response of airline stock prices to a COVID-19 shock is not explained by a COVID-19-induced increase in airlines’ variable costs, but rather by a COVID-19-induced decrease in air travel, which, in turn decreases revenues, profitability, and stock prices of U.S. airlines.     

A study on the impact of airline service delays on emotional reactions and customer behavior

This study is intended to identify the influence of service delays on emotional responses and customer behavior. For this research, a survey was conducted on airline passengers that experienced service delays. A total of 395 respondents were analyzed using structural equation modeling. According to the analysis results, service delays positively influenced negative emotions and negatively influenced repurchase intention. In addition, service delays positively influenced negative word-of-mouth. This study provides a basic knowledge on how airlines can develop their service strategies to make good use of the motivating effect of service delays on emotional responses and behavioral intentions.     

The impact of low cost airline entry on competition, network expansion, and stock valuations

We conduct event studies and statistical analysis to explore the impact of low cost carriers’ entry on legacy airline stock prices. Oligopoly structures, entry barriers, and high fixed costs make the airline industry highly susceptible to competitive and network expansion impact of low cost airlines’ entry. Positive stock returns are observed, which we interpret as the spillover effects of network expansion. Thus, rising passenger traffic and improved connectivity increase the revenues of legacy airlines to sufficiently offset the low cost carriers’ competitive threats.     

Study of the topology and robustness of airline route networks from the complex network approach: a survey and research agenda

Communication via air routes is an important issue in a world organized around a web city network. In this context, the robustness of network infrastructures, e.g. air transport networks, are a central issue in transport geography. Disruption of communication links by intentional causes (e.g., terrorist attack on an airport) or unintentional (e.g., weather inclemency) could be crucial for countries, regions and even the airlines affected themselves. Policymakers and the management of airlines and alliances should be able to reduce the effects of such interruptions in order to ensure good communication through air transport (i.e., maximize the robustness of their network at a reasonable cost). The literature review of the study of air transport route networks through an analysis of complex networks has highlighted a lack of contributions to the study of the topology and the robustness of such networks which contrasts, with advances undertaken for other transport networks or communication systems. This survey suggests areas in which research should be undertaken, based on the existing literature in other areas and from three different perspectives: global route networks, airline alliances, airlines and airports so as to help towards a better understanding of air traffic and, therefore, to be able to assess the potential damage of any airport being inoperative for a continent, country or airline.     

The impact of social media and offline influences on consumer behaviour. An analysis of the low-cost airline industry

This study analyses the impact of social media as well as offline environments upon tourist online purchase and recommendation behaviour of low-cost airline services. Drawing on the Theory of Reasoned Action (TRA), this research considers the effect of offline social influences (interpersonal and external influences) and analyses online Consumer-to-Consumer (C2C) information exchanges as a driver of customer attitude towards online purchases. We propose that these factors improve online repurchase intentions and positive word-of-mouth communication (WOM and e-WOM) in low-cost settings. Using structural equation modelling, the conceptual model is tested with a sample of 441 Spanish Internet buyers of low-cost airline services. Interpersonal offline influences (e.g. friends, relatives, and family) have a significant effect on online repurchase intentions and WOM but do not affect e-WOM. External offline influences (e.g. media and experts), however, only affect consumer intentions to recommend future purchases of low-cost airline services on social networking travel sites and have no effect on online repurchase intentions or WOM. Findings also show that online C2C information exchanges influence attitude which, in turn, has a significant effect on repurchase intentions WOM and e-WOM.     

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.     

Integrated recovery of aircraft and passengers after airline operation disruption based on a GRASP algorithm

This paper considers the integrated recovery of both aircraft routing and passengers. A mathematical model is proposed based on both the flight connection network and the passenger reassignment relationship. A heuristic based on a GRASP algorithm is adopted to solve the problem. A passenger reassignment solution is demonstrated to be optimal in each iteration for a special case. The effectiveness of the heuristic is illustrated through experiments based on synthetic and real-world datasets. It is shown that the integrated recovery of flights and passengers can decrease both the recovery cost and the number of disrupted passengers.
