This study examines international tourism as a legacy of hosting the Olympics. Prior research has hypothesized that the host city will have sustained increases in international tourism as a result of hosting the Olympics. The increase in tourism is largely attributed to the positive media coverage of the sporting event and the host city. In this research, international air passenger traffic for six Olympics is analyzed. Time series models are used to analyze the effect of the Olympics as an intervention in the series. The magnitude, shape and duration of the intervention are modeled. The results show no sustained increase in international tourism for five of the six host cities. Only half the sites show an increase in international tourism during the Olympics.
