This presentation examines the potential of seaplanes as a transport solution in Greece, focusing on improving connectivity for island communities, accommodating growing tourism demand and addressing sustainability concerns. Despite being discussed for over a decade, seaplane operations have not been successfully established in Greece. Through interviews with international stakeholders, we identify key characteristics of seaplane operations across the world and barriers to their success, and we assess their sustainability challenges. We highlight the need for close collaboration between policymakers and operators as a key driver for successful seaplane operations in Greece, and we provide a critical discussion of the potential role of seaplanes in the Greek market. Finally, we recommend that evidence-based policymaking is essential to ensure new transport solutions meet socio-economic and environmental objectives.
