ABSTRACT
At first glance, most airports look alike, but they are not. Apart from their vast differences in size, they may differ profoundly in terms of their function within the city or region in which they are located and in value of the airlines operating within them. DESTEP stands for Demography, Economy, Social-cultural, Technology, Environment and Political stability. By analyzing these factors in the catchment area, we can assess demand for air travel to and from the airport that is located in the centre of that catchment area. In situations where cities with an airport are located close to one another we often see competition between airports, whereby the airport closest to the city, such as Haneda Tokyo, has the advantage over a competing airport further away, like Narita.
