The proposed survey for this research did not follow all of the original 22 Survqual item; instead, items were modified, added or deleted when planning the survey instrument. For this reason, the questionnaire developed by working group, which consist of 5 dimensions and 46 statement (expectations-23; perceptions-23), was adapted to the airport firm and applied to the departing passengers. Systematic sampling was adopted with a “skip interval” of every 10th individual arriving at the entrance of Sabiha Gokcen Airport. The questionnaire was prepared in 4 languages: Turkish, English, German and Russian. Of those originally distributed, 296 completed passenger surveys were collected in August 2005.
