This study aimed to examine the impact of the Theory of Planned Behavior on Malaysian luxury hotel selection. To achieve this objective, the study examined the influence of attitude, subjective norms, perceived behavioral control, and fake reviews on the choice of luxury hotels in Malaysia. The study also investigates whether intention mediates the relationship between these variables and luxury hotel selection. The research method was quantitative in nature and to collect the necessary data, convenience sampling was used on an online questionnaire, resulting in 400 valid responses. The respondents were residents of Malaysia aged over 18 years old who had stayed at luxury hotels before, as they are qualified to answer the research objectives. For this study, four- and five-star hotels are considered as luxury hotels. The collected data were then analyzed using IBM SPSS version 26, using descriptive, regression, and mediation analysis through Hayes process. The results from the regression analysis revealed the predictive power of each variable, while the mediation analysis demonstrated that intention mediates the relationship between attitude, subjective norms, and perceived behavioral control in luxury hotel selection. According to this study, attitude, subjective norms, perceived behavioral control, and fake reviews influence luxury hotel choices. Intention significantly mediates the association between attitude, subjective norms, perceived behavioral control, fake reviews, and luxury hotel choices.
