Abstract
The flight choice behavior of Korean people for long-distance international air trips that take more than 10 hr air journey time was studied. Separate logit choice models were calibrated with revealed preference (RP) data and stated preference (SP) data, and the comparative analysis and the complementary interpretation of RP and SP data were tried. Required data were collected by the survey at Kimpo International Airport in Seoul, Korea, in 1993 and 1994. Journey time, air fare, service frequency, and nationality of airline were identified as major factors influencing flight choice in the market. It is remarkable that Korean airlines were considerably preferred in the market. Most Koreans are not fluent in English or other European languages and are not accustomed to western culture. This results in their preference for Korean airlines. Value of travel time and other trade-off ratios among variables to evaluate the relative importance of each factor were also identified through the results of RP and SP data analysis.
