Abstract

The authors analyze Eurostat’s air-passenger data for 29 European countries during three reference years – 2018 (pre-COVID), 2020 (COVID-19), and 2023 (recovery). By applying the k-means clustering method on standardized variables heterogenous recovery patterns are classified. Model selection is supported by the Elbow method, Silhouette approach, and Calinski–Harabasz index. The findings reveal heterogeneous recovery by 2023. All clusters are reported in detail including percentage changes and robustness checks. Managerial and policy implications for air transport and tourism (capacity planning, route development, targeted incentives) and information technologies’ contribution to enhancing analytical processes and supporting data-driven decision-making are discussed.
