The present study is based on initial research investigating the causal relationship model among LMX, empowerment, and the organizational effect adapted to a domestic airline with perceived organizational support as a moderating variable, and it is intended to empirically probe the causal relationship among factors and the moderating effect according to perceived organizational support. Eventually, we intend to help manage employee attitudes and offer customer service managers implications to obtain an organizational effect. As a result, sub-factors of empowerment can be composed of three factors such as competence, impact and self-determination. LMX enlarges empowerment ability, especially competence and self-determination which have positive effects to job satisfaction and organizational commitment, respectively. However, as an exception, the impact did not have an effect on job satisfaction and organizational commitment. There is a causal discrepancy between the perceived group and non-perceived group according to perceived organizational support, and especially, we found a relative discrepancy in the path of self-determination and job satisfaction. The present study has some limitations such as restraint of domestic airlines and neglect of causal discrepancy according to airline size, at home or abroad.
