An Analysis of the Efficiency of Long-Range Routes of Full Service Carriers: The Case of Incheon International Airport

Purpose This study analyzes the efficiency of long-rage routes of domestic full service carriers operating at Incheon International Airport in South Korea and provide directions for the enhancement of efficiency and competitiveness of routes. Design/Methodology/Approach This study collected data from homepages of airlines and OAG (Official Airline Guide) analyzer. The DEA analysis was performed using the number of flight operations, total flight distance, and supply of seats as input variables, and sales revenue and RPK (Revenue Passenger Kilometers) as output variables. Findings Results reveal that three international long-range routes (A Airlines’ Incheon~Frankfurt, Incheon~Barcelona and K Airlines’ Incheon~Zurich routes) were the most efficient routes out of 63 routes analyzed. In addition, K Airlines’ Incheon~Dallas, Atlanta, and Seattle routes had the lowest efficiency. At the same time, if the efficiency of 63 routes was divided into two groups, A and K Airlines, and averaged, K Airlines had more than twice the number of routes compared to A Airlines, but overall efficiency of the routes covered by A Airlines was higher. Research Implications This Implies that routes with relatively low efficiency were more efficient if the number of flights, total annual distance and supply of seats were reduced. In addition, in order to build more efficient routes, airlines have to benchmark high-efficiency routes to control the number of flight operations, total flight distance, supply of seats and total supply of seats, and marketing strategies to increase average fare and increase boarding rate.
