The subject of this thesis is the analysis of the current situation in order to determine the possibilities of future development of air passenger traffic in the Republic of Croatia. The paper analyzes the key factors important for the current development and for the future perspective of rail passenger traffic in the country. A key factor in the development so far is certainly the deregulation and liberalization of the market, as well as political stability and the environment. Furthermore, tourism is an important factor, while the future direction of development is largely dependent on the current global pandemic caused by the Covid-19 virus. In accordance with the presented subject, the aim of the work, based on a detailed analysis, was to determine the future of the development of air passenger traffic in the Republic of Croatia. In order to achieve the goal of the work, secondary and primary data were used. In the primary research, a structured interview reminder was used as a research instrument, and the interviewees were experts in charge of transport policy and air transport. The aim of the primary research was to determine the assessment of the current state of air passenger traffic in the Republic of Croatia as well as the strategy for its further development. Empirical research has established that air passenger traffic in the Republic of Croatia is more developed compared to 5 or 15 years ago. But it is still not adapted to global trends and the environment, although positive developments due to liberalization and privatization are visible. Management, coordination and connection of stakeholders are mostly mentioned as the key to the solution. Also, addressing seasonality should be a priority policy.
