This study explores the mesoscopic intricacies governing the interplay of regional and interregional traffic flows within the world air transportation network. We adopt a network decomposition method, the component structure, to partition the network into local and global components, aligning with geographical and cultural boundaries. We explore the centrality and the core of these unweighted and weighted networks. The analysis of centrality highlights distinctions between airports with high traffic and those with high degrees. This contrast is particularly pronounced in the global air network and its largest component. Additionally, core analysis reveals similarities between the s-core and the k-core for local and global components, despite the latter encompassing more airports. In the world air network, North and Central America-Caribbean airports dominate the s-core, while European airports take precedence in the k-core. Interestingly, airports distant from their component’s core can also rank among the top high-strength airports. This comparative analysis underscores the component structure representation’s vital role in uncovering regional and interregional dynamics within the world air transportation network, providing valuable insights into its mesoscopic structure and implications for global air travel.

    Moreover, we explore the strength and the s-core of these networks. Results display fewer local components well delimited and more global components covering the world than the unweighted world air transportation network. Centrality analysis reveals the difference between the top airports with high traffic and the top airports with high degrees. This difference is more pronounced in the global air network and the largest global component. Core analysis shows similitude between the s-core and the k-core for the local and global components, even though the latter includes more airports. For the world air network, the North and Central America-Caribbean airports dominate the s-core, whereas the European airports dominate the k-core.
