Abstract
The primary goal of this study was to develop a theory-based model of relationship commitment in an online travel context. Leaning on the foundations of marketing literature and the two theories of relationship commitment (organizational commitment theory, and investment model), this study develops a conceptual framework that explains how Generation Y develops commitment to a travel web vendor. Affective commitment and calculative commitment were found to vary in terms of their impact on word-of-mouth communications. The results showed that the affective commitment was most effective for developing and maintaining long-term relationships with Generation Y. In addition, the study suggested that investment size was positively related both to affective commitment and calculative commitment. Finally, satisfaction was found positively related to affective commitment and negatively related to calculative commitment. The theoretical and managerial implications were discussed as well.
