With the increase in wine consumption in flight, wine service quality has become an important factor in determining passenger satisfaction. But few studies have examined quality issues in delivering in-flight wine services. This study examines the effects of wine education on flight attendants` job performance, perceived organizational support, and job satisfaction, and examines the role of wine involvement in those relationships. Flight attendants in one of the major airline companies in Korea have participated in our survey. The survey includes questions about perceptions of wine education on three attributes(``professional,`` ‘systematic,`` and ``practical``), wine involvement, job performance, perceptions of the organization`s support, and job satisfaction. The findings indicate that the systematic attribute of wine education is important in influencing job performance, perceived organizational support, and job satisfaction. They also indicate that wine involvement moderates the relationship between wine education and job performance. This study provides practical implications on wine service management for the airline industry.
