This paper aims at identifying the state of academic research on the influence of Internet on tourism consumer behaviour. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Methodology was used to select the data and the analysis was complemented with bibliometric indicators. This research identified 83 relevant articles related to the influence of Internet on tourism consumer behaviour. The systematic review of the academic literature demonstrated that the Internet influences tourism consumer behaviour during the entire travel cycle stages. During the pre-consumption stage, motivations and decision-making process are highly influenced by several online sources. However, in the case of expectations, limited research was found on this area. Value co-creation behaviour is influenced by Internet during the final two stages of the travel cycle stages. Finally, evidence suggests that loyalty is influenced during the consumption and post-consumption stages. These results provide a categorized analysis of the influence of Internet on the behavioural variables during each of the travel cycle stages for academicians and practitioners. The analysis was conducted on two major academic databases: Web of Science Core Collection and Scopus. The inclusion of other data sources and other types of secondary data could complement these results.
