Klagenfurt Airport — Klagenfurt am Wörthersee, Austria

KLU serves Klagenfurt, capital of the Austrian state of Carinthia and a city built along the shore of the Wörthersee, an alpine lake whose relatively warm summer water temperatures have made it one of Austria's most popular domestic resort destinations for generations. The airport shares its site with an Austrian Armed Forces base, a common arrangement at regional airports across the country, and handles a modest mix of scheduled and seasonal charter flights that swell noticeably each summer as tourists head for lakeside hotels and swimming beaches. Surrounded by the Alps, Carinthia trades on both winter skiing in higher elevations and warm-weather lake tourism lower down, giving KLU two distinct seasonal peaks rather than a single dominant travel period. The writer Ingeborg Bachmann, one of postwar Austria's most acclaimed literary voices, was born in Klagenfurt, and the city hosts a literature prize named in her honor that draws visitors through the airport each summer.
