In general the study findings have coincided with other studies that the quality of airlines’ services has a significant influence on passenger satisfaction and loyalty. Findings indicated that pre-flight, in-flight and post-flight services had a significant effect on passenger satisfaction. In addition to that, passenger satisfaction as a mediating variable also had a significant effect on passenger loyalty. The study results imply that airline marketers should develop various strategies to improve service quality, for example, meeting passengers’ desired service levels, improving the quality of in-flight meals, solving service problems effectively, developing convenient reservation and ticketing systems, making convenient schedules for passengers and reducing the effect of service failures as these directly affect passenger satisfaction and loyalty.
