The customer engagement construct has been widely investigated in the marketing literature since 2005. Scholars in hospitality and tourism have perceived the importance of this construct and tried to propose both conceptual framework (e.g., So, King, Sparks, & Wang, 2016) and measurement scale to capture this phenomena (e.g., So, King, & Sparks, 2014). However, there is no consensus in many issues such as conceptualization (Dijkmans, Kerkhof, & Beukeboom, 2015) and dimensionality (Romero, 2017). In addition, this construct is relatively new in hospitality and tourism. Hence, the direction for future research and what has been done in the past are indispensable for researchers since it reduces research fragmentations in the future. The study aim is to use existing works in hospitality and tourism literature with the systematic literature review to summarize facts and address the future research. SCOPUS and ISI were employed as the main databases to search and identify the relevant articles. A total of 19 out of 590 documents was identified and selected to analyze and classify based on types of research, country, and journal. In addition, the issues of theoretical background, conceptual framework, conceptualization, dimensionality, statistical analysis, key contributors are summarized respectively. Finally, this study addresses the scope of potential future research in a realm of hospitality and tourism.
