Globally, air passenger demand has increased significantly, but the speed of expansion of airport infrastructure has not been able to meet the growth rate of demand. Therefore, one of the important tasks of congested airports around the world, including IATA, is to use airport slots more efficiently. In this study, we introduce a contention slot allocation model as a way to improve airport slot efficiency. The most basic principle of slot allocation is the Grandfather Rule. That is, if more than 80% of the allocated slots are used, the right to use the slot is continuously recognized. This study analyzes which allocation method uses slots more efficiently when competition occurs between airlines in the process of redistributing the recovered slots excluding vested slots. The slot efficiency measurement index uses the number of air transport passengers per slot. [Model 1] is the competition slot allocation method, and the lottery method in accordance with the Seoul Regional Aviation Administration's Detailed Operation Guideline for Aircraft Operation Time Adjustment is applied. In [Model 2], the airlines with the highest number of air transport passengers per the number of airline operations in the previous year are allocated first. As a result, the following implications were obtained. First, we build two models by establishing a mathematical model based on the economic efficiency of slots in NERA (2004), McDonald (2006), and Bauer (2008). Second, the operational effectiveness of [Model 1] and [Model 2] was demonstrated through empirical analysis as a way to improve the economic inefficiency of the slots of Level-3 airport that could be caused by the existing auction.
