The Statistics Korea reported that 32.5% of the population in 2022 is generation MZ, and their purchasing power is increasing. Also, studies in various fields have been published on generation MZ recentely, but the emergence of studies comparing the differences between generations M and Z can be seen as a proof of the need to approach generation M and Z separately. This study is an empirical study comparing the differences in types of overseas travel products purchased by generation M and generation Z, and 400 people from 200 of generation M and 200 of generation Z were responded using the convenience sampling method at Incheon International Airport from January 6 to 15, 2023. As a result, generation M preferred a packaged travel and generation Z preferred Air-tel travel. On the other hand, the types of travel products that sold only airline tickets and accommodation showed low interest in both generations. Cost-effectiveness was the most considered factor for both generations when selecting overseas travel products. It is tended that generation Z was more faithful to itself and generation M to convenience.
