The airport shared by three countries is Geneva Airport (GVA).
Located in Switzerland, Geneva Airport is also used by residents of France and the French region of Haute-Savoie. This is because the airport is situated close to the border between Switzerland and France, with a portion of the airport's land falling within French territory. This unique situation makes it a shared airport facility serving three different countries.
Geneva Airport serves as a crucial hub for international travel, connecting travelers across Europe and beyond. It is a significant economic driver for the region, contributing to the prosperity of Switzerland, France, and Haute-Savoie.
