In this study airline service quality was measured following (SERVPERF) approach and depended on categorising services according to the stages of services provision to passengers. This is the first time ever, that an attempt has been made to identify airline service quality based on services provision to passengers. Beyond the dimensions suggested to identify airline service quality, the use of pre-flight, in-flight and post-flight service classification, offers the opportunity to examine the importance that can be made according to passengers' evaluations of the airline services in these different stages.

This approach can be applied to other services where the service provider can classify services into: before providing the service, during the service and after providing the service. This will enable the service provider to control all the stagesa nd therefore it will be easier to identify where problems occur and how to cover the situation should problems occur.
