How a Bangkok airport became the world's busiest hub for low-cost budget airlines
In short: Don Mueang International Airport was once slated for permanent closure to make way for a modern successor. Instead, it reinvented itself as a global powerhouse for budget travel. Today, this historic airfield operates as a vital, high-traffic gateway, proving that even aging infrastructure can find a second life in aviation.
Established in 1914 as a Royal Thai Air Force base, Don Mueang is among the oldest operating airports in Asia. For most of the 20th century, it served as Thailand’s primary international hub. Its status as the country's main gateway ended in 2006 with the opening of Suvarnabhumi Airport, which was intended to replace it entirely. However, operational constraints and safety concerns at the new facility led to a rapid reversal of policy. By 2007, Don Mueang was reopened, eventually transitioning into a dedicated center for low-cost carriers.
The airport's resurgence was cemented in 2012 when the government abandoned its single-airport strategy to ease congestion at Suvarnabhumi. This shift allowed Don Mueang to thrive as a regional budget hub. By 2015, it had surpassed major international airports like Barcelona–El Prat and Las Vegas to become the world's largest airport for low-cost airlines. This growth was marked by significant infrastructure investments, including the renovation of Terminal 2 and the ongoing development of a third terminal, which aims to push total capacity to 50 million passengers annually.
Beyond its commercial role, the airport remains a unique joint-use facility shared with the Royal Thai Air Force. Its layout is famously unconventional; a golf course sits directly between the two runways, where players must pause whenever an aircraft lands. While the airport faces physical limitations—such as the inability to build additional runways—it continues to manage high volumes of traffic by encouraging airlines to utilize larger, wide-body aircraft. Today, it stands as a critical component of Southeast Asian aviation, balancing its historic roots with the demands of modern, high-density travel.
The airport's evolution reflects the broader shifts in global aviation, where secondary hubs often absorb the overflow of primary international gateways. Despite being officially closed in 2006, the facility proved indispensable to the regional economy. With its current focus on domestic and regional routes, it serves as the primary base for major budget airlines like Thai AirAsia and Nok Air, ensuring its continued relevance in the competitive landscape of international air travel.
