This study aims to analyze the queuing system, service performance, and utilization of the two runways at Soekarno-Hatta Airport, Tangerang, Indonesia. The number of aircraft movements at the airport at busy hours exceeds capacity, resulting in long queues. This study uses a quantitative approach and queuing theory with a single server multi-channel queuing system. Discussion of runway service performance at Soekarno-Hatta Airport, by calculating the Queuing System State Probalilities to determine the probability of n units (arrivals) in the system. Five equations have been analyzed in order to Evaluation of the Two Runway Queue System. The findings of this study provide a signal for optimizing airport operator runway utilization by developing runway capacity and adding infrastructure as well as adding taxiways, aprons, and runways. The increase in runway capacity will have an impact on more aircraft services, which also means more effective and efficient runway utilization. To improve the queuing system, it is necessary to improve queuing system services with regular training of directly related officers so that the queuing system can be more effective and efficient. To improve the performance of runway services, it is necessary to increase the capacity of the navigation tools currently owned.
