This study focuses on investigating the relationship between tourist quality service, satisfaction and loyalty among international visitors who came to Vietnam. Specifically, this research also aims to discover the mediating effects of tourist satisfaction on the relationship between tourist quality service and loyalty (revisit and recommend to others). By using the data collected from 516 international visitors who travelled in Vietnam, authors use a meta-analytic path analysis to show that only two factors of tourist quality service had significant effects on tourist satisfaction and loyalty, including tangibles and responsiveness. Moreover, tangibles and responsiveness not only had direct effects, but they also they had some indirect impacts on tourist loyalty throughout tourist satisfaction. Interestingly, the relationship between tourist satisfaction and their loyalty was strongest.
