Abstract
Air carriers and aircraft manufacturers are investing in technologies and strategies to reduce fuel consumption and associated emissions. This chapter reviews related issues to assess airline fuel efficiency and offers various empirical evidences from our recent work that focuses on the U.S. domestic passenger air transportation system. We begin with a general presentation of four methods (ratio-based, deterministic frontier, stochastic frontier, and data envelopment analysis) and three perspectives for assessing airline fuel efficiencies, the latter covering consideration of only mainline carrier operations, mainline–subsidiary relations, and airline routing circuity. Airline fuel efficiency results in the short run, in particular the correlations of the results from using different methods and considering different perspectives, are discussed. For the long-term efficiency, we present the development of a stochastic frontier model to investigate individual airline fuel efficiency and system overall evolution between 1990 and 2012. Insight about the association of fuel efficiency with market entry, exit, and airline mergers is also obtained.

Abstract
This chapter provides a survey of alternative methodologies for measuring and comparing productivity and efficiency of airlines, and reviews representative empirical studies. The survey shows the apparent shift from index procedures and traditional OLS estimation of production and cost functions to stochastic frontier methods and Data Envelopment Analysis (DEA) methods over the past three decades. Most of the airline productivity and efficiency studies over the last decade adopt some variant of DEA methods. Researchers in the 1980s and 1990s were mostly interested in the effects of deregulation and liberalization on airline productivity and efficiency as well as the effects of ownership and governance structure. Since the 2000s, however, studies tend to focus on how business models and management strategies affect the performance of airlines. Environmental efficiency now becomes an important area of airline productivity and efficiency studies, focusing on CO2 emission as a negative or undesirable output. Despite the fact that quality of service is an important aspect of airline business, limited attempts have been made to incorporate quality of service in productivity and efficiency analysis.

Abstract
This chapter considers the productivity of 77 airlines between 1980 and 2013. We do so by estimating a stochastic frontier and decomposing the total factor productivity growth into efficiency, technical and scale efficiency change. Our results show that, on average, airlines increased productivity over the period but that, while efficiency and technical change improved, scale efficiency results indicate that the average airline moved away from the most productive scale size. This was especially so in the two decades after 1980. Comparisons between geographical areas, business models, networks and alliances are also made.

This paper aims to present the findings of an investigation into environmental reporting practice in the airline sector.
Abstract
Purpose
This paper aims to present the findings of an investigation into environmental reporting practice in the airline sector.
Design/methodology/approach
Evidence was gathered from an international survey of 272 IATA Airlines. Responses accounted 65 per cent of the world's scheduled passenger traffic. Reports were assessed against a framework developed by UK's Association of Chartered and Certified Accountants.
Findings
The paper demonstrates that, despite an increase in the availability of quantitative data and some consistency in the use of key performance indicators, comparing social and environmental performance across the airline sector is fraught with difficulties. Variations in the exact definitions of the indicators used and the suite of functions embraced by the term “airline” are identified as fundamental obstacles to effective sector benchmarking.
Practical implications
Insight into an understanding of some of the pros and cons of comparisons between airline environmental performance data.
Originality/value
The research highlights the limitations of inter airline comparisons regarding environmental data and confirms the need for environmental and social impacts to be reported in a more standardised manner in order to facilitate meaningful dialogue with stakeholders in communities adjacent to airports.

Abstract
Purpose
The objective of this paper is to review the latest management developments across the globe and pinpoint practical implications from cutting‐edge research and case studies.
Design/methodology/approach
This briefing is prepared by an independent writer who adds their own impartial comments and places the articles in context.
Findings
The paper finds that, with thousands of planes airborne every day, passengers tucking into their lunch at 35,000 ft as they cross continents, and some military aircraft stealthily getting up to 55,000 ft with the ability to reach anywhere in the world within a few hours, few are surprised that aviation is constantly reaching, metaphorically speaking, new heights. But what of the impact on the environment?
Practical implications
The paper provides strategic insights and practical thinking that have influenced some of the world's leading organizations.
Originality/value
The briefing saves busy executives and researchers hours of reading time by selecting only the very best, most pertinent information and presenting it in a condensed and easy‐to digest format.

Abstract
Purpose
The study compares the corporate social responsibility (CSR) actions of two sectors of hospitality, tourism and travel (hotels and airlines) by researching what Six Sense hotels (a hotel brand) and Air Canada (an airline company) have been doing in order to respond to the 17 Sustainable Development Goals (SDGs) and how they apply the concept of CSR in their operational activities. The article also considers how these activities align with quality-of-life (QoL) dimensions and contemporary CSR dimensions.
Design/methodology/approach
Provides a detailed comparative, case study analysis of the reported CSR practices of companies in different sectors of the hospitality and tourism industry based on competitive strategy; environmental protection; internationalization of CSR; and transparency and accountability. The impact of the varied initiatives on quality of work life (QWL) and QoL is also considered together with implications for the circular economy (CE).
Findings
Analysis of the two case study examples suggests that these companies' activities are designed to promote sustainability. The findings also suggest that there is a positive relationship between CSR activities and QoL that the case study companies are aware of this and are doing all they can to sustain this relationship given the benefits it yields.
Originality/value
Uses case study analysis of Six Senses Hotels Resorts & Spas and Air Canada to conduct a comparative analysis of the reported CSR practices of companies in different tourism sectors based on competitive strategy; environmental protection; internationalization of CSR; and transparency and accountability.

Abstract
Purpose
The purpose of this study is to propose a methodological approach for modeling catastrophic consequences caused by black swan events, based on complexity science, and framed on Feyerabend’s anarchistic theory of knowledge. An empirical application is presented to illustrate the proposed approach.
Design/methodology/approach
Thom’s nonlinear differential equations of morphogenesis are used to develop a theoretical model of the impact of catastrophes on international business (IB). The model is then estimated using real-world data on the performance of multinational airlines during the SARS-CoV-2 (COVID-19) pandemic.
Findings
The catastrophe model exhibits a remarkable capability to simultaneously capture complex linear and nonlinear relationships. Through empirical estimations and simulations, this approach enables the analysis of IB phenomena under normal conditions, as well as during black swan events.
Originality/value
To the best of the author’s knowledge, this study is the first attempt to estimate the impact of black swan events in IB using a catastrophe model grounded in complexity theory. The proposed model successfully integrates the abrupt and profound effects of catastrophes on multinational corporations, offering a critical perspective on the theoretical and practical use of complexity science in IB.
