Karlovy Vary Airport — Karlovy Vary, Czech Republic

KLV serves Karlovy Vary, a spa town whose thermal mineral springs have drawn the ailing and the fashionable alike since the fourteenth century, when the Bohemian king Charles IV reportedly discovered the hot springs while hunting and gave the town his name. Grand colonnades and bathhouses built during the town's nineteenth-century heyday still line the Teplá River, a legacy of visits by figures ranging from Goethe and Beethoven to Russian aristocrats who once favored the resort as a summer retreat. Each summer the town also hosts the Karlovy Vary International Film Festival, one of the oldest competitive film festivals still running and a significant draw for European and international cinema, adding a burst of traffic through KLV during festival week. The airport itself remains modest in scale, with scheduled and charter service historically skewing toward Russian visitors before geopolitical shifts reduced that traffic, alongside smaller domestic and regional European connections.
