The paper presented estimates the expenses of Swiss travellers by means of a hedonic regression. Based on the constituting elements of a trip (number of travel companions from the same household, duration of trip, choice of destination, means of transport and accommodation), the overall costs of a trip (expenses) are estimated by log-linear regression. The results reveal that the travel expenses per person and trip underproportionally increase in the case of an increase of distance and duration, with an underproportional negative effect of the number of participating household members. The value drivers identified are the number of participat-ing household members (with regard to domestic tourism) and the duration of a trip (with regard to international tourism). Overall, the type of accommodation has the comparably highest elasticity.
