At the end of 1997, AviAlliance won the bidding for Düsseldorf Airport in the first partial privatization of an airport in Germany. AviAlliance holds 30 percent of the shares, while Aer Rianta holds 20 percent. The City of Düsseldorf has retained a 50 percent interest. In 2023, Düsseldorf Airport recorded 19.1 million passengers.

Düsseldorf Airport is located in one of Europe's strongest economic regions with 18 million inhabitants within a radius of 100 kilometers and thus plays an outstanding role in meeting the mobility needs of people and companies in the region.

At the Skytrax World Airport Awards 2024, Düsseldorf Airport was recently awarded second place in the category “Best Regional Airport in Europe”. These awards, which represent one of the most prestigious distinctions in the aviation sector, are presented annually on the basis of an independent passenger survey in which passengers are asked, among other things, about how satisfied they are with airport services, check-in, the quality of passenger services and security standards.
