In some cases, international airports generate up to 50 percent of their overall annual revenue by marketing and renting space, in other words through non-aviation business. Parking maintenance at an airport plays a large part in this. 2,000 to 3,000 euros per parking space per year is not an uncommon rate. However, a study by QUINTA Consulting shows that European airports, unlike U.S. airports, are nowhere close to maximizing the revenue potential offered by professional parking management.
