In this study, we empirically analyzed how the psychological capital perceived by travel agency counselors affects organizational commitment and organizational citizenship behavior. Hope, confidence, resilience, and optimism were presented as sub-factors of psychological capital. In addition, organizational commitment was differentiated from previous studies by dividing it into affective commitment and continuance commitment. The subjects of the survey were travel counselors who sell travel products at a domestic travel agency located in Seoul, and 205 people were used as a sample. As a result of verification, it was found that all four sub-factors of psychological capital had a positive effect on affective commitment. However, it was found that there was no significant effect on continuance commitment. The two sub-factors of organizational commitment were found to have a positive effect on organizational citizenship behavior. These results mean that psychological capital and affective commitment play an important role in increasing counselors' organizational citizenship behavior. Finally, it made an important contribution by presenting practical implications in terms of human resource management to strengthen the affective commitment and organizational citizenship behavior of travel counselors.
