<![CDATA[Soekarno-Hatta International Airport, one of Indonesia's busiest airports, faces the challenge of high air traffic congestion. Airlines, including low-cost carriers (LCCs) like Citilink, play a crucial role in this congestion dynamic. This study aims to analyze the influence of Citilink airline flight traffic on traffic density at Soekarno-Hatta Airport and identify factors that influence the choice of flight schedules and routes. The research method employed is a mixed-methods approach that combines quantitative and qualitative methods. Quantitative data in the form of daily departure data from November 14, 2024, to January 31, 2025, were analyzed using simple linear regression with the help of SPSS and JMP Pro. Meanwhile, qualitative data were obtained through structured interviews with the Flight Permit Lead of PT. Citilink Indonesia. The results show that Citilink flight traffic has a significant impact on density at Soekarno-Hatta Airport, contributing 25.7% to total density, 59.6% on the busiest route (Jakarta-Denpasar), and 15.7% during peak hours. It was also found that the main factors influencing flight schedule selection are market demand during peak hours, a focus on priority routes, and an operational strategy that emphasizes On-Time Performance (OTP) and coordination with AirNav Indonesia.]]>
