Ú Zurich hub ensures value creation Swiss aviation and the businesses that supply it employ approximately 180,000 people. The resulting value added amounts to 30 billion Swiss francs, the greater part of which is attributable to operations at Zurich Airport. In 2012 Flughafen Zürich AG commissioned a study on the macroeconomic importance of Zurich Airport from Arbeitsgemeinschaft Infras/BAK Basel. In addition to an analysis of Zurich Airport’s direct and indirect effects on employment, which have already been men- tioned, its contribution to value creation, its relevance to tourism, air cargo transport, the export trade, and the factor of location, accessibility also came under consideration. The study provides evidence for the great economic importance of this air travel hub for Switzerland. Ú Hamburg Aviation cluster The Hamburg metropolitan region is, along with Seattle, Washington, and Toulouse, France, one of the aviation industry’s most important centers worldwide. With 40,000 employees, more than 9,000 of whom work for various companies of the Lufthansa Group, aviation is the largest industrial sector in the region. One of the crucial factors in the suc- cess of the aviation industry in Hamburg is the level of cooperation across companies. Alto- gether, some 300 aviation companies, insti- tutes of higher learning, and public authorities cooperate within the Hamburg Aviation indus- try cluster alongside the three giants of the industry: Airbus, Lufthansa Technik, and the airport. Lufthansa Technik devotes substantial resources to research and development along with training and continuing education. ß 12 Lufthansa’s Munich hub. 13 Zurich: An important hub for Swiss. 14 Hamburg Airport: The largest base of opera- tions and the head- quarters of Lufthansa Technik AG.
