Comment: in GreekTechnological developments worldwide are contributing to the improvement of transport infrastructures and they are helping to reduce the overall transport costs. At the same time, such developments along with the reduction in transport costs are affecting the spatial interdependence between the regions and countries, a fact inducing significant effects on their economies and, in general, on their growth-rates. A specific class of transport infrastructures contributing significantly to overcoming the spatial constraints is the airtransport infrastructures. Nowadays, the importance of air-transport infrastructures in the economic development is determinative, especially for the geographically isolated regions, such as for the island regions of Greece. Within this context, this paper studies the Greek airports and particularly the evolution of their overall transportation imprint, their geographical distribution, and the volume of the transport activity of each airport. Also, it discusses, in a broad context, the seasonality of the Greek airport activity, the importance of the airports for the local and regional development, and it formulates general conclusions.
