The number of consumers who book travel tickets online is growing. But a switch from offline environment to online environment creates certain doubts in the minds of consumers. Such doubts have been termed as perceived risks in literature. This study is carried out to understand the behavior of consumer under such circumstances. The differentiations between two competing environments give rise to risk perceptions. For instance, over the Internet information about a variety of websites is at consumers’ finger tips and this is not the case in offline environment. But this huge amount of information leads to perception of loss of time in finding the appropriate travel website. As a consequence, such risk perceptions restrict consumers in booking tickets over the Internet. A multiple-case- study research was undertaken. The findings indicate that the online environment is more convenient, easy to search, compare and book tickets. The consumers in this study book tickets over the internet and do not perceive (significant level of) any risk. They also believed that it was very difficult to book form a risky website. The consumers book tickets from websites which are perceived as risk free. Any risk perception negatively effect consumers’ willingness to book tickets over the Internet.
