Banja Luka International Airport — Mahovljani, Bosnia and Herzegovina

Banja Luka International Airport carries the code BNX and sits in the village of Mahovljani, a short drive from Banja Luka, the largest city in Republika Srpska and the second-largest in Bosnia and Herzegovina. Elevation here reaches 400 feet, and a single runway handles everything the field sees. Despite its large-airport classification, BNX handles a relatively modest volume of scheduled traffic compared with Sarajevo, and its route network has shifted over the years alongside changes in airline ownership and demand. It nonetheless plays an important regional role, connecting Republika Srpska to destinations in Western Europe favored by the Bosnian diaspora, including Germany, Austria, and Switzerland, where many families settled after the 1990s conflict. The terminal has been renovated in stages to modernize passenger facilities and expand check-in capacity. For travelers and cargo operators serving the Bosnian Krajina region, BNX remains the closest air link, sparing them a long road trip to Sarajevo or Zagreb whenever an international flight is needed for business or family visits.
