Gilze Rijen Air Base — Rijen, Netherlands

GLZ is the code for Gilze-Rijen Air Base, a military airfield located near Rijen in the Netherlands and operated by the Royal Netherlands Air Force. Gilze-Rijen has a long aviation history dating back to the early twentieth century and today hosts helicopter units and search-and-rescue operations rather than civilian airline traffic. The base plays a role in Dutch and NATO defense activities, and its runway occasionally supports civil emergency use given the helicopter capabilities stationed there. Because it is primarily a defense installation, GLZ does not appear in typical commercial flight booking systems, and public access is restricted compared to civilian airports. Its presence reflects the Netherlands' broader network of dual-use and military aerodromes scattered across the country's compact geography.
