When thinking of international airports, bustling hubs like JFK or LAX might come to mind. However, nestled in the town of Houlton, Maine, lies Houlton International Airport (IATA: HUL)—a modest facility that holds the distinction of being the smallest international airport in the United States. Despite its size, this airport boasts a rich history and continues to serve its community with dedication.

Originally established as Houlton Army Air Base during World War II, it played a pivotal role in military operations. Post-war, the facility transitioned to civilian use and was designated as an international airport due to its proximity to Canada and its customs facilities.
