The purpose of this study is to present competitive strategic implications for the Asia-Pacific airlines by analyzing the relative operational efficiencies among them. We conducted two analyses using the panel materials by IATA and the financial statements and performance data provided by ICAO, ATW, and the websites of individual airlines. First, we analyzed the operating performance measures of the Asia-Pacific airlines by using DEA (data envelopment analysis) method. Second, we identified the characteristics of productivity of the Asia-Pacific airlines by a profiling method. The results showed that the airlines presenting multi-product services rather than those with limited services were more efficient as they practiced economies of scale added by economies of scope such as the expansion of routes through strategic alliance to improve their performance.
