Tourism is strongly related to infrastructure and services: in this case should be mentioned the presence of low cost airlines, that have changed the dynamics of air travels and consequently of tourism, allowing cheap travels. According to this concept in the period of economical recession the development of such infrastructures as airports, railway stations, roads and their prices becomes very important to improve tourism sector in Italy. The attractiveness of the territories not only depends on the natural and cultural heritage but also on the level of areas’ promotion and the level of development of infrastructures, services, means of transportation, hotels, prices, etc. The aim of this paper is to construct a composite indicator that would explain airports’ organization, where the important features are selected and weighted through the method of principal component analysis. To aggregate these components two methods were chosen: the first is the linear aggregation sum and the second is the rank method. Interesting results were attained implementing the correlation analysis to verify the robustness of two methods and the differences between them. This work is the first step to comprehend the influence of the development level of infrastructures on domestic and international tourism.
