Odense Hans Christian Andersen Airport — Odense, Denmark

Denmark's third-largest city lends this airport more than just its name, since the honorary addition of Hans Christian Andersen recognizes the fairy-tale author born in Odense in 1805, whose childhood home in the old quarter remains a major cultural attraction today. The airport itself, reachable by the code ODE, has seen its scheduled passenger service shrink over the years as improved rail links, including a direct connection across the Great Belt Bridge, made Copenhagen an increasingly convenient train journey from Odense rather than a short domestic flight. Two runways, one paved and one grass, give the airport flexibility for general aviation and smaller aircraft even as larger scheduled carriers have periodically come and gone from its route map. Odense sits on the island of Funen, positioned roughly midway between Copenhagen and the Jutland peninsula, a geography that has shaped how much air service the airport could sustain against strong rail competition.
