In the past, it was enough for the airport to have a runway and a modest terminal. The development of air traffic has also increased customer requirements (passengers, airlines, etc.), which has affected the need for airport infrastructure development. Throughout the world, passenger terminals have been built, many of which, according to architectural solutions, represent works of art. The design and functionality are tailored in such a way as to enable longer stay and meet the requirements of passengers and other users. Content and concept offer solutions that airport operators provide for additional revenue. One part of the content and service is offered in passenger terminal buildings, while the other part is provided outside them, whether in or outside the airport. Part of this content is offered by Airport City (AC). AC phenomenon represents the integration of infrastructure, superstructures, information and operations. It represents a part of the Supply Chain (SC) and usually includes facilities such as: passenger terminals, runways and other airport activities such as: ground handling, logistics, office space, shops, hotels, etc. In this paper, authors use a method of systems theory, a modeling method and a comparative method as a general and some specific scientific methods of cognition, to researching the problem to which different AC models and their structure can contribute to the optimal SC flow as its essential part and bring the results of the AC phenomenon as a part of the SC.
