This paper estimates the impact of entrance of low cost carriers to Eastern Asia international passenger transport markets, especially to the high density short haul markets, and discusses the efficient management policy of multiple airport system. We apply the bi-level air transport market model to Osaka-Korea international passenger transport market, and estimate the impact of entrance of low cost carriers. The results suggest that the entrance of LCC improves passenger's utility, but the legacy carriers lose their profit seriously. We also evaluate the slot allocation policy, i.e. using ITM as an international airport. Finally we find that using ITM policy is workable for protecting the legacy carrier's share, but the effect will disappear with the increase of passenger's sensitivity to airfare.
