Objective: To perform a rigorous systematic review of the literature, with the aim of identify the most relevant studies on emotional intelligence and positive affect and their relationship with customer satisfaction in the tourism industry, and a bibliometric analysis of scientific production to lay the foundations of such relationships. Theoretical Framework: This paper presents the key concepts and theories that underpin the research. Emotional intelligence, positive affect and customer satisfaction in the tourism industry are highlighted to provide a solid basis for understanding the context of the research. Method: The methodology used in this research is based on the Constructivist Knowledge Development Process (Proknow-C), which facilitates the organisation of a systematic literature review to select and analyse bibliographical references and generate the necessary knowledge. Results and Discussion: The resulting portfolio of 17 relevant articles in line with the object of the study made it possible to identify the main approaches proposed by the authors on this subject. In essence, the review of the literature showed a clear consensus on the relationship between the emotional intelligence and positive affect of service providers and customer satisfaction in the tourism industry. Research Implications: This research is useful for the academic community in conducting significant and relevant research on the study axes, laying the foundations to continue advancing in future lines of research. In addition, the results are profitable from a professional standpoint. Organizations in the tourism sector may reflect on and promote best practices in developing emotional and positive affect skills among their service staff given their influence on customer satisfaction. Originality/Value: This study contributes to the literature as scientific research on this subject remains scarce. Furthermore, the results can have an impact on the performance of tourism businesses and thus on the economic development of the destination.
