The data are analysed using a variety of statistical techniques. Factor analysis is used to identify the main factors of airline service quality and passenger loyalty. The segmentation of airline passengers according to their loyalty levels and psychographic characteristics is performed using cluster analysis techniques. LISREL 8 and path analysis techniques are used to investigate the relationships among the three constructs namely: service quality, passenger satisfaction and passenger loyalty. The key findings of the study indicate that overall service quality is highly related to both passenger satisfaction and loyalty. The relationship between passenger satisfaction and loyalty toward a specific airline is less clear.
