Nowadays, e-commerce is ubiquitous across various industries, encompassing the marketing of numerous products and services, including tourism services. Global travel agencies have embraced the provision of personalized customer service online. In this context, the aim of the study is to examine the effect of e-service quality and brand image for online travel agencies (OTA) on e-trust, e-satisfaction and e-loyalty. Data were collected through an online survey method from a sample of 1176 respondents. The collected data were analyzed employing confirmatory factor analysis and path analysis using the AMOS program. The findings of the conducted analyses unveiled that e-service quality exhibited a negative impact on e-trust, e-satisfaction, and e-loyalty for online travel agencies, whereas the brand image exerted a positive influence on e-trust, e-satisfaction, and e-loyalty. Consequently, it can be inferred that customer services delivered via electronic platforms should be prominently positioned in the travel market, with particular emphasis on brand image.
