This chapter explores the dynamic intersection of global tourism geography and the evolving architecture of airline connectivity, emphasizing their interdependence in shaping international travel patterns and economic development. As air transport continues to serve as the primary mode for international tourist arrivals, facilitating over 58% of cross-border travel according to the UNWTO (2023), understanding its spatial, economic, and infrastructural dimensions becomes essential to tour planning and destination development. The chapter begins with an analysis of tourism geography, examining how accessibility, geopolitical relationships, and cultural appeal influence travel flows across world regions. It then investigates the role of airline networks, including hub-and-spoke vs. point-to-point models in structuring these flows, highlighting the transformative impact of low-cost carriers (LCCs) in unlocking underserved markets and decentralizing tourism benefits. Drawing from IATA’s (2023) Global Connectivity Index, the chapter provides a regional breakdown of air access disparities and their implications for tourism competitiveness. Additionally, the chapter assesses the impact of the COVID-19 pandemic on global connectivity, emphasizing the fragility of international tourism systems and the strategic adaptations made by airlines, such as fleet resizing, digital health verification, and flexible scheduling. The discussion further extends to the environmental considerations of air tourism, including emissions management under CORSIA and the emergence of sustainable aviation fuels (SAFs). The final section forecasts future trends in tourism geography, where digital innovation, environmental stewardship, and geopolitical cooperation are positioned as critical drivers of resilient, equitable, and sustainable tourism networks. By aligning geographic analysis with aviation economics and regulatory insight, this chapter equips readers with a comprehensive understanding of how air connectivity underpins global tourism mobility. It provides both conceptual frameworks and real-world applications for planners, policymakers, and tour operators seeking to design efficient and sustainable air-tourism systems in a post-pandemic world.
