This study explores perceived accessibility specific to air transportation in the Dutch context through a focus group study. Five focus group sessions were held with a total of 24 participants with air travel experience within the past five years. Online focus groups were held during the period that the COVID-19 pandemic travel restrictions were in effect, specifically around 12 months after the travel restrictions were implemented globally. In terms of the importance of activities accessible by flight, we observe that travelers particularly attach importance to visiting family and relatives, while the importance attached to the business and recreational activities accessible by flight varies among participants. As far as the transport component of accessibility is concerned, we find that, in addition to conventional variables in air transportation research, such as cost and travel times, unconventional variables such as uncertainty during flight schedule disruptions or the mood of staff and other passengers contribute to perceived accessibility by air transportation. Based on the results, we further discuss characteristics specific to perceived accessibility by air transportation, directions for further qualitative and quantitative research regarding perceived accessibility by air transportation, and implications for policy and planning.

Air transportation is a mode of transport developed specifically to provide access to long-distance destinations that may otherwise be infeasible or at least more difficult to reach. Accordingly, there are distinct aspects of air travel that require consideration when assessing accessibility by air transportation, which are not addressed in general local accessibility studies. This paper reviews studies of accessibility by air transportation. The studies in question were published in academic journals, and we analysed them using the broad theoretical framework of accessibility of Geurs and van Wee [Accessibility evaluation of land-use and transport strategies: Review and research directions. Journal of Transport Geography, 12(2), 127–140]. We discuss the characteristics of accessibility by air transportation to consider when designing research, as well as trends and knowledge gaps in the existing literature. An important gap is that, while there is a growing interest towards perceived accessibility by air transportation, accessibility measures based on this perspective have not yet been applied yet. Additionally, the literature is largely focused on the transport and land-use components of accessibility as opposed to the individual and temporal components. We finish by discussing the benefits and drawbacks of directly applying conventional accessibility measures for research on accessibility by air transportation, as well as options to modify the temporal component of conventional person-based accessibility measures for better applicability in the air travel context.

With the introduction of the carbon emission cost system initiated by the Carbon Offsetting and Reduction Scheme for International Aviation(CORSIA), the improvement of fuel efficiency in flight operations will have higher impact on airline profitability than before. In-flight fuel consumption is somewhat influenced by pilots’ technical actions when maneuvering aircraft during flight. This study investigated pilots’ recognition and implementation of fuel efficient aircraft controls. The required data were collected using a survey on a sample of pilots from multiple airlines. This survey examined their awareness of fuel saving measures and the implementation of those measures during flight operations. The data were analyzed via Analytical Hierarchy Process(AHP) and Importance-Performance Analysis(IPA). It was determined that pilots recognized the cruise phase to have the highest potential fuel savings with shortcut route selections. Power idle descents were considered second in terms of fuel saving potential. On the other hand, the pilots did not significantly recognize or implement factors related to operations on the ground.
