Facilities The airport covers an area of 383 hectares (946 acres) of land and features one passenger terminal, two runways and extensive logistics and maintenance facilities. Linz Airport is relatively small, with 11 gates. There is a shop and café in the entrance hall, connected to the check-in and airline desks. Beyond the security checks there is a duty-free shop and a small café accessible from both the domestic and international gate areas. The airport also has a roof terrace, which can be visited during the summer months between 6 and 23 o'clock to observe the airplanes. For guests of the airport the access is free of charge. The rooftop also has a playground for children. For so called plane spotters special viewing spots were created, where visiters are able to take pictures of the planes from a wide range of angles without having to worry about any annoying obstacles. The airport is equipped with a 3000 meter long precision runway with two instrumental landing systems, as well as a helicopter landing pad. For medium-haul aircraft 16 parking positions are available. Linz Airport is actually a military airport but with a civil right of use. The civil part is located north of the landing strip.

The Cargo sector of the airport operates worldwide under the brand Air Cargo Center. In 2017 there was a significant cargo increase with a total of 53,796 tons of cargo. Thus the airport could strengthen its leading position as Austria's largest regional airport for cargo services and further increase cargo services by more than 20% compared to last year.
