The non-CO2 aviation emissions (mainly contrails) can, in total, be up to twice as damaging for climate as the CO2 emissions associated to the use of kerosene. As the warming effect of the non-CO2 emissions depends strongly on metereological conditions, it is difficult to attribute the non-CO2...

Air transport is crucial for ensuring population mobility owing to time travel savings, especially in remote regions. Despite its benefits, air transport is still one of the most polluting industries worldwide. Under the European Green Deal, sustainable transport needs to be enhanced to promote...

Purpose - The research identifies the impact of the Russia-Ukraine war on the stock prices of six publicly traded European airlines and evaluates their ability to adapt to this situation. Research methodology - The dependence of the development of airline stock prices on the level of public and...

This paper estimates passenger benefits from airline flight frequencies, recognizing that this task is less straightforward for connecting trips than for nonstop travel. In doing so, the paper joins Yuan and Jia (2026) as the only other study in the literature that confronts the problem of...

The European Union Emissions Trading System is set to substantially increase the effective carbon price faced by airlines. To quantify the impact of this carbon regulation on the European airline industry, we estimate a two-stage model of airline competition with endogenous route entry, flight...

Sustainable aviation fuels (SAFs) are promising solutions for reducing carbon emissions in the aviation industry and achieving the 2050 net-zero target. Despite their environmental benefits, the adoption and deployment of SAFs remain significantly below expectations. This paper systematically...

Die Dekarbonisierung des Luftverkehrs stellt eine erhebliche Herausforderung dar und erfordert entschlossene politische Maßnahmen sowie starke Anreize für den Einsatz nachhaltiger Flugkraftstoffe (Sustainable Aviation Fuels, SAF). Derzeit kommen sowohl marktbasierte als auch regulative...

The COVID-19 pandemic profoundly disrupted global aviation networks, with long-haul connectivity particularly affected. This study assesses the evolving competitive positions of sixteen major hub airports in the Asia-Pacific region by analyzing their transfer-connectivity performance before and...

The aviation industry is facing pressure from stakeholders to transform towards greater sustainability. From a managerial and marketing perspective, not only the actual implementation and achievements of sustainability measures, but also their communication to stakeholders is likely to be...

Background: Defining the optimal fleet portfolio is a crucial process in airline planning. The published efforts in literature provide ways to anticipate the disruption effects on the passenger demand; however, the proposed solution in this paper provides visibility on the impact of sustainable...

The paper analyzes how aircraft acquisition structures - leased versus owned - affect airline performance. It considers the controlling role of business models, specifically low-cost carriers (LCCs) and full-service providers (FSPs). Using financial and operational data from 142 airlines...

Background: Air traffic control is a stressful job and vital to aviation safety. Although technological developments have been introduced to enhance and facilitate the tasks of air traffic control officers (ATCOs), ATCOs still experience high levels of job stress. This study explores the...

The primary motivation for this study is the recent growth and increased interest in artificial intelligence (AI). Despite the widespread recognition of its critical importance, a discernible scientific gap persists within the extant scholarly discourse, particularly concerning exhaustive...
