Maastricht Aachen Airport — Maastricht, Netherlands

Despite sitting entirely within the Netherlands, Maastricht Aachen Airport carries the name of a neighboring German city in its title, a nod to the tri-border region where the Netherlands, Belgium, and Germany meet and where the airport, coded MST, draws much of its catchment population. Cargo operations make up a disproportionately large share of its business compared with many regional airports of similar size, with cut-flower shipments and other time-sensitive freight moving through its facilities to markets across Europe. Passenger service has historically been smaller and more volatile, shaped by seasonal charter flights and the occasional low-cost route rather than a stable year-round network. Maastricht itself, a historic city known for its Roman-era origins, university, and role in the 1992 treaty that helped shape the European Union, sits a short drive from the airport. Limburg province's relatively small population keeps demand modest, even as the region's central European location offers logistical advantages.
