摘 要:Since the outbreak of the COVID-19 pandemic early in the year 2020,the aviation system has been under extreme pressure for more than two years,with many stakeholders anticipating the moment of recovery.In Summer 2022,eventually,many airlines reached profit margins again.Several airlines even reported to outperform pre-pandemic indicators,including the number of passengers and quarterly revenues.Accordingly,one could say that 2022 is part of the new normalcy in our global aviation system.In this study,we investigate the changes in the global aviation,comparing the year 2019 as a pre-pandemic baseline with the aviation system throughout the year 2022.The connectivity of nearly 8,000 cities worldwide is compared and underlying drivers identified through the design of adequate econometric models.We find that the largest extent of recovery has taken place in secondary cities.We find a rather heterogeneous spatial recovery pattern,which indicates the necessity to better understand the differences in the current aviation system.Moreover,changes of global connectivity indicators,e.g.,betweenness centrality,seem to be of rather complex nature.Our study contributes towards a better understanding of the post-pandemic global aviation system and concludes with a set of future research directions,which can hopefully guide other researchers to identify open challenges for the new normalcy.
