Aerotropolis guru Dr. John Kasarda has written an in-depth article for Sodexo, one of the world’s largest firms. Entitled ‘Aerotropolis: Airports as the new city center‘ it is informative on how the aerotropolis serves the interests of aviation oriented global businesses. Airports serve as corporate headquarters and, apparently, the business space at some major airports, such as Paris Charles de Gaulle, is larger than the city’s central business districts. The article also indicates the scale and extent of aerotropolis developments worldwide: ‘Airport city and aerotropolis development is gaining substantial traction, multiplying rapidly on a global scale…. I’ve identified over 80 airport cities and broader aerotropolises (airport-centered urban economic regions) around the world that are either already operational or in early stages of development.’
