Increasingly air transport growth raises the question of its impact on the environment. Public authorities and researchers are relying more and more on high-speed trains (HSTs), whose efficiency is ...supposed to lead to a modal shift from airplanes. However, most transport studies focus on the evolution of demand rather than supply, although it is basically the latter that determines environmental damage. In light of this fact, this paper aims to compare the overall dynamics in the supply of air transport in Europe compared to the HST supply and to examine empirically five city-pairs. The development of high-speed rail remains limited compared to the increase of air services. For a given city-pair, the decline in the number of flights depends on various conditions, including length of the HST journey and the strategies adopted by the airlines. Some carriers reduce their supply in terms of the number of seats but increase the number of flights in order to compete more effectively with the HSTs. Moreover, the competition between low-cost airlines and HSTs should be kept in mind and re-examined in a few years.
► HSR remains spatially limited compared to the expansion in the supply of air transport. ► Travel time seems to remain a strong factor of intermodal competition. ► The decline in the number of flights depends on various conditions. ► HST services may face fierce competition from low-cost airlines. ► Results call for exhaustive multifactorial analysis of competition.
The transportation sector plays a major role in the rapid economic growth of developing countries. Since this sector requires large amounts of fossil energy resources, it has a very important impact ...on global warming and greenhouse gas emissions. As aviation has a significant contribution to carbon dioxide (CO2) emissions among different type of transportation, there is considerable interest in policies, regulations and research to mitigate the adverse effects of aviation on climate 1. This work investigates the role of air passengers and air freight on CO2 emissions from aviation for eight oil-producing countries in the middle east for the years 2013–2019. Maximum entropy bootstrap for time series and generalized maximum entropy estimation are used in this work, which represent two powerful techniques that lead to reliable and stable results in ill-posed models. The empirical results confirm the existence of a positive impact of air passengers on CO2 emissions from air transport in all the sample countries. But the connection between air freight and CO2 emissions from aviation is only confirmed for Iran and Qatar. The findings for the other countries regarding the impact of air freight on CO2 emissions from aviation depend on the significance levels considered.

Resilience is the ability of a system to withstand and stay operational in the face of an unexpected disturbance or unpredicted changes. Recent studies on air transport system resilience focus on ...topology characteristics after the disturbance and measure the robustness of the network with respect to connectivity. The dynamic processes occurring at the node and link levels are often ignored. Here we analyze airport network resilience by considering both structural and dynamical aspects. We develop a simulation model to study the operational performance of the air transport system when airports operate at degraded capacity rather than completely shutting down. Our analyses show that the system deteriorates soon after disruptive events occur but returns to an acceptable level after a period of time. Static resilience of the airport network is captured by a phase transition in which a small change to airport capacity will result in a sharp change in system punctuality. After the phase transition point, decreasing airport capacity has little impact on system performance. Critical airports which have significant influence on the performance of whole system are identified, and we find that some of these cannot be detected based on the analysis of network structural indicators alone. Our work shows that air transport system’s resilience can be well understood by combining network science and operational dynamics.
Air transport demand forecasting is receiving increasing attention, especially because of intrinsic difficulties and practical applications. Total passengers are used as a proxy for air transport ...demand. However, the air passenger time series usually has a complex behavior due to their irregularity, high volatility and seasonality. This paper proposes a new hybrid approach, combining singular spectrum analysis (SSA), adaptive-network-based fuzzy inference system (ANFIS) and improved particle swarm optimization (IPSO), for short-term air passenger traffic prediction. The SSA is used for identifying and extracting the trend and seasonality of air transport demand and the artificial intelligence technologies, including ANFIS and IPSO, are utilized to deal with the irregularity and volatility of the demand. The HK air passenger data are collected to establish and validate the forecasting model. Empirical results clearly points to the enormous potential that the proposed approach possesses in air transport demand forecasting and can be considered as a viable alternative.

The COVID-19 pandemic has affected the Airline Industry in many aspects. This has brought changes in many aspects of the lives both as service providers and service receivers in the air transport. ...Social distancing and other restrictions have significantly impacted the stakeholders in the airlines industry. In addition, several airlines faced more challenges after the reopening of the services and operations since adaptation of the new standards and procedures have set the limitations. Therefore, organizational planning and managing crisis are relevant. This research aimed to discuss relevant information in relations to e-service which could support the management levels to contribute to the crisis management strategic planning. The author adopted qualitative analysis by applying the in-depth interview. This research investigated how two airlines in Thailand had managed the disruptions and other disturbance caused by the COVID-19 pandemic. The respondents in the study were 8 managers working in two different airlines in Suvarnabhumi airport. This was conducted in April- May 2022 to study the relevant information in relations to the effectiveness of the strategy. The management in the Airline industry will benefit from this set of information and be able to help organizations in air transport to respond to current situations.
Information Technology is vital in all organizations especially in the air transport. This paper reviews how information technology (IT) impacts organizations in the aspect of customer service. The ...authors are interested in the implication of online service of 5 different airlines towards passengers’ behaviors. Many organizations in the Airline Industry see the importance of the e-service and aim to add the value in the Information Technology. This led the researcher to investigate ways fororganizations in the air transport to adapt quickly and grow rapidly. This is one of the vital tools for organizations in the air transport to increase customers satisfaction. Thus, this study was conducted to investigate the relationship of customer satisfaction and the information technology of airlines industry. The respondents were 88 passengers using e-service offered by 5 airlines in Thailand. The findings reported top 3 relevant factors affecting customer satisfaction that can set as guidelines for organizations in air transport.
This academic article reviews the air transport in Thailand, specifically the situation and the outlook. The authors surveyed and collect the data from secondary sources both internally and ...internationally including the public sector annual report, private, and academicians. The situation has been predicted into three phase cases including; best case scenario, moderate, and worst-case scenario. Additionally, the service quality, the reskills and upskills for employee acquiring new skills, the organization transformation, and the technology adaptation are required. More importantly, the health safety plan and policies of air carriers shall be implemented and communicate to the public to assure their safe journey. Meanwhile, the adoption of technology could also minimize the repetitive work and human contact but it could provide new air travel experiences. The earliest the air transport industry was revitalized; it means the socioeconomic improvement.
Drawing on an overarching framework of marketing theory, this study develops and tests an integrated model of service quality that explicates the affective mechanisms through which service quality is ...associated with price perception of service (e.g., monetary price and behaviour price), word of mouth (WOM) and revisit intention. In a sample of 484 low-cost airline passengers, we found service quality to be related to increased price perception of service as a result of increasing passengers' WOM, which also creates success in this regard by increasing their revisit intention. Moreover, it is not surprising that there was a positive relationship between service quality and WOM mediated by perceived value of monetary price. The theoretical and empirical implications of these results are discussed.

This paper examines the causal relationship between air transport and economic growth in the South Asian context. Using panel data over a period of 42years (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 3–4years should guide aviation firms and policy makers in the preparation of necessary infrastructure required to support the strong air transport growth potential.

This paper examines the impact of High-Speed Rail (HSR) on the domestic Chinese aviation passenger market. Our dataset comprises a panel of 642 air and HSR routes from 2007 to 2014. During rapid HSR ...expansion from 2010 to 2014, the number of air passengers per route grew 32% for destinations that did not compete with HSR, but fell 7% for routes that faced HSR competition. A difference-in-differences approach shows that the introduction of HSR leads to more than a 50% fall in air travel over two years. Increased frequency of daily HSR routes further contributes to economically large declines in air passengers. The negative effects of HSR introduction and additional daily service to air travel increase substantially over-time and the recent expansion of HSR to Central and Western regions in China dampens demand for air travel more than coastal regions. These factors point to future challenges for aviation as China plans to expand rapidly HSR service inland.
