The tourism sector is undergoing change with the growth of Information Communication Technology (ICT). These changes mainly affect the methods through which the tourism products and services are communicated and distributed to the customers around the world. Retention of the customers is a major challenge in today's competitive market and unsatisfied customers can easily switch from one service provider to other service providers. So it is necessary to provide quality services to the customers. But it is not possible to serve customers only through traditional means of distribution. It is thus necessary to provide tourism-related services to the customers with the help of ICT. Hence, an attempt has been made in the current study to develop a model in order to study the factors affecting the use of online service quality in the tourism sector. Data has been collected with the help of primary survey. Exploratory Factor Analysis has been applied to analyze the collected data. Eight factors have been identified, namely, website design, informative, ease of use, reliability, responsiveness, empathy, security and system availability. Further, CFA was applied in order to validate the model. The results revealed that all the indicators had adequate item reliability, further establishing the validity of the constructs.
