Pricing and service quality are the key variables that decide the brand equity of each player in the airline industry. Existing literature suggests that measurement and management of service quality is the key for survival of airline companies. This research paper examines the service quality delivered by four major airlines in India on the backdrop of stiff competition in the airline service sector. The process of traveling on a domestic airline was divided into pre-flight, in- flight and post-flight experiences.Asurvey was conducted to find out the perceived service quality of frequent fliers on each of the four airlines across a series of service performance variables. The airline brands were positioned in a perceptual space, where the perceived service attributes were also mapped. Clear differences emerged among the airlines, with two of them perceived as being similar to each other, and the other two differing in many respects.
