From the beginning of aviation background to the nowadays, people's demands and needs have also changed with the changes in their lifestyles and technological developments. In this process, airports show a change towards commercialization and urbanization by getting rid of traditional practices under increasing competition conditions. These changes and developments lead airports to seek new applications that will increase their revenues. Now, airports appear as both centers that establish transportation and centers that perform entertainment, culture-arts, tourism, technology, logistics, service and production activities together. Airports have transformed from a traditional business model to a commercialized business model and an urbanized business model in the process. This transformation has also led to diversification in airport revenue sources. When the aviation-based income sources of traditional airports are examined, it is seen that the most important income sources are aviation incomes. In commercial and city airports, it is seen that the share of non-aviation income sources is important in addition to aviation revenues. Within the scope of the study, the top 10 airports in 2021 according to the Skytrax ranking were examined. In the study, data were collected by making use of secondary data sources as a result of annual reports published by airports and literature review. The data obtained were analyzed by content analysis, one of the qualitative research methods. The business models of the airports that are the subject of the study are presented and the income structures that change and differentiate under intense competition conditions are explained. According to the conclusions of the article, the revenues of the airports examined were collected under three main headings as revenues from technological, social and sustainability activities.
