Linz Airport (, ) is a minor international airport located in Hörsching, near Linz, the third-largest city in Austria. It is also known as the Blue Danube Airport. History Early years Air traffic used to take place at the Südbahnhofmarkt in the center of Linz where the zeppelin Estaric I took off on 30 October 1909. In 1925 air traffic was established between Linz and Vienna. Starting in 1934, the air traffic operation was based in the Linz-Katzenau district (nowadays industrial center), which was later terminated by the NSDAP after 1938. The airport was then moved to Hörsching. The following table shows some of the units of the Luftwaffe (air force in Nazi Germany), which were deployed from 1943 to 1945. Since 1956 regular passenger air traffic takes place. Since 1966 daily flight connections to Frankfurt Airport are available. Development since the 1970s In 1972 a passenger terminal was built and was officially opened in 1976. Since 1985 the flight path is equipped with an Instrument landing system, category IIIb.
