The current demand in tourism is characterized more frequent trips throughout the year, but shorter than before.. Yet even though this trend will have an adverse affect on the hospitality industry, it will benefit the travel industry. Most of the current literature is based upon the premise that the variables determining travel participation are the same ones that influence travel frequency. However they need not be the same nor behave in the same manner in terms of participation and travel frequency. The aim of this study is to identify the variables that influence the travel frequency of Spanish seniors, one of the most important collectives for the tourism industry given its high travel frequency which depends on variables determining travel participation. Our results show that the variables gender, self-perceived economic status and self-perceived time available determine Spanish senior travel frequency.
