A look at the world’s most desolate airports. We start with Mid America St. Louis Airport, a facility originally conceived as a burgeoning hub to augment the operations of Lambert St. Louis International Airport. Despite its grand architectural design and potential to accommodate both domestic and international travelers, the airport has struggled to attract consistent airline operations, largely due to its proximity to a more established airport and insufficient passenger demand.Then we visit the new Siem Reap Angkor International Airport in Cambodia, a project launched in response to the burgeoning tourism in 2025, surrounding the iconic Angkor Wat. With state-of-the-art infrastructure designed to handle millions of passengers, the airport’s reality starkly contrasts its ambitions; it grapples with underutilization and fierce competition from other regional airports. The Cambodian government remains hopeful about its potential role in bolstering the nation’s tourism and economic landscape, yet the challenges it faces underscore the complexities inherent in fostering growth in less accessible regions.Then we tell story of Ciudad Real Central Airport in Spain. Once envisioned as a pivotal European transit hub, it too met an untimely demise due to operational failures and financial miscalculations, culminating in its bankruptcy within just three years of operation. This trajectory of decline across various global airports serves as a sobering testament to the volatility of the aviation sector, and how sometimes airports can come back from nearly dead, as in Worcester Mass Airport.
