In this study, the method uses factor analysis to describe factors affecting purchase decisions and subsequently Analytic Hierarchy Process defines the priorities among the rivals depending on the findings of first part. Output of the model provides us to specify the factors that affect priorities from the passengers’ perspective. Hereby model can help to enhance items according to priorities.
