service quality construct was measured based on instruments developed by Parasuraman et.al., (1988) consisting of reliability, responsiveness, assurance, empathy, and tangible dimension.
As the nature of this studi is predictive, as suggested by scholars (Cronin& Taylor, 1992; Zeithaml, et al., 1996) the measurement of service quality is usingSERVPERF rather than SERVQUAL. Customer satisfaction was anchored by satisfactionwith the service and quality and quantity of product such as food and beverage.
Price wasoperationalised by a single item. All of these variables were measured with five Likert scale:strongly disagree (1) to strongly agree (5).
Prior to data collection, all of the items to measure the constructs have been consulted to airlines experts and practitioners to ensure their contentvalidity.
In addition, reliability test of service quality and customer satiation variable hassatisfied the reliability requirement as the valuee of Cronbach Alpha is above 0.70.
