This study investigates the operational efficiency between the major airlines of two countries: China and Korea. We consider three major Chinese airline companies, namely, Air China, China Southern Airlines, and China Eastern Airlines, and two major Korean companies, specifically, Korean Air and Asiana Airlines for this comparative study. In examining the relative operational efficiency of these airlines, we considered both passenger transport and freight shipment. In addition, among these five airline companies, we evaluated the output performance based on the operating input factors using Data Envelopment Analysis (DEA). Five input factors consisted of the human aspects (amount of labor and labor cost), physical capacity aspects (available seat kilometer and available ton kilometer), and operating expenses. The output factors include revenue passenger kilometer, revenue ton kilometer, and flight revenue. Output performance was analyzed according to the base of the three separate categories of operating input aspects using DEA, and each of the five airline companies was evaluated and compared in terms of relative operational efficiency, respectively. The comparative analysis showed which airline companies were relatively inefficient in terms of which categories of input aspects. At the end of this study, we suggested performance improvement directions in order to achieve higher operating efficiency for each of the five airline companies.
