Because stewardesses have to work based on irregular schedule and go abroad, they are assumed to have more conflicts between work and family than other married working women. Thus this study is aim to examine the effects of conflicts between work and family on the job satisfaction of married stewardesses in airline companies. A survey using questionnaire including questions about factors of conflicts, level of work interference with family (WIF) and family inteference with work (FIW) and job satisfaction was conducted. The findings of the study were as follow: First, the result of the analysis on whether work conflict factors affect WIF significantly showed that the higher the overtime, role conflict and role overload, the higher they recognized the WIF. Second, the result of the analysis on whether the family conflict factors affect FIW significantly showed that among the factors, economic problems and child care increase FIW. Third, both WIF and FIW impact negatively on job satisfaction. Considering that the portion of married stewardesses increases in airline companies, findings of the study suggests that the airline companied need to make more efforts to reduce both FIW and WIF.
