The senior tourism is getting more and more attention in many countries as the importance of this market segment becomes more evident. This is strengthened by political initiative/project, where generous financial aids are offered to develop promotion and communication activities to disseminate the transnational packages and raise awareness on the tourism offer for seniors (EU-Commission, 2013) could be interpreted as a possible under-served trend within tourism. This thesis aims to give insight into how the senior tourism is defined and how it is served by the Swedish main stream travel companies. Further in this thesis the authors are trying to find an answer if the market segmentation where senior citizens would be defined as a specific market segment, would benefit the companies.
