Abstract. The article studied the economic efficiency of the runway was determined by the example of the Tashkent International Airport. Taking into account the conditions of a seasonal increase in the flow of aircraft in order to increase runway capacity, a method has been created to determine the economic efficiency of increasing runway capacity. As a result, a method has been developed to determine the economic efficiency of the runway, which increases the capacity of the airfield runway in conditions of seasonal air flow growth. At the same time, what type of operation the aircraft belongs to in the case of using the traffic lane and the fast lane, as well as the amount paid for the runway. The economic efficiency of using the airfield runways in the conditions of seasonal growth of air flow at Tashkent International Airport as a factor in increasing the efficiency of the runway capacity has been determined. As a result, it was found that in conditions of seasonal growth in the flow of aircraft, it is possible to achieve an increase in economic efficiency by 10%, that is, to save 878,710,848 soums per year.
