Aviation has developed as an indispensable means of transportation with the industry expanding faster than most other industries. Moreover, since it is the world's only means of rapid transportation, it becomes essential for global business, facilitating international trade and tourism. At the same time, the airline industry is also known for its fierce competition and tight profit margins. This implies that it is extremely important to design the right strategies that could increase productivity and competitive advantage. The combination of business intelligence and analytics has become an important area in the business environment of airlines and aviation organizations, which are used to analyze large amounts of data and make business decisions based on the results obtained. In order to present and compare data clearly and comprehensibly as possible, Microsoft Power BI was used in this work, which made it possible to present research results and trends in passenger transport and aircraft operations in the Republic of Croatia in a meaningful and acceptable way. The conducted research clearly recorded the increase in passenger transport and the recovery of air traffic in the Republic of Croatia after the crisis caused by the COVID-19 pandemic. The recovery was largely contributed by low-cost airlines, which carefully select destinations and business routes with their special sales strategy and operational efficiency.
