competition is an inevitable factor Similarly it happens with the airline industry, especially in Vietnam’s low cost airlines market Low airfare ticket is not a unique factor to compare but customer service is also very important Low cost airlines are also trying to understand their customers, to measure their passengers’ satisfaction because passengers’ satisfaction may guarantee good customer loyalty for their future business This study will provide a better understanding of how passenger satisfies with Vietnam’ low cost airlines about customer service and air fare Based on the result of this study, airline managers may understand their level of service and improve it During this study, the author measures service quality dimensions and air fare impact on customer satisfaction via SEVRQUAL tool of (Parasuraman et al., 1988) With a sample of 150 passengers who had travelled on Vietnam’s low cost airlines flights within month is surveyed at Tan Son Nhat airport included Jetstar Pacific Airlines and Vietjet Airlines passengers to test six hypothesized relationships among the construct of impacted of service quality and air fare on customer satisfaction The study also finds that the important dimensions of service quality tested here is: tangibles”, “reliability”, “responsiveness”, “assurance”, “empathy” and “air fare” The study used Statistic Package for Social Science (SPSS) to analyze data through Exploratory Factor Analysis (EFA) and regression analysis tools The results indicated that all dimensions have strong positive effect on customer satisfaction Keywords: SERQUAL, Service Quality, Customer Satisfaction, Low Cost Airlines, Vietnam CHAPTER INTRODUCTION 1.1 Vietnam’s low cost airline background: This study examines in the context of low cost carrier (LCC) operating in Vietnam There are two LCC operating in Vietnam, ( Jetstar Pacific Airlines since 2005 and Vietjet Air since 2011) Vietnam’s airline market is a market with a population of 88 million, shared by airlines (included Vietnam Airlines, Jetstar Pacific, Vietjet Air, Air Mekong, Vasco) almost operating domestic and short-haul routes but Vietnam Airlines is a flag carrier of Vietnam with both domestic and international routes In the situation of Vietnam changing from agriculture to a service market, we are opening the door to welcome foreign investments from all over the world, standard of living higher, moreover indoor and outdoor tourist market developing… as a result, the demand of air transportation increasing significantly It creates a potential airline market in Vietnam Nevertheless, airline industry has been continuous operating on extremely thin margins (IATA, 2011; Tiernan et al., 2008/1) with high operational costs (Airline Trends and Ancillary Revenue Report, 2010) Thus, the volume is crucial for the industry to stay profitable; the differences in prices for one flight can be huge Furthermore, the actual product of the airline industry (airline seat) is extremely perishable Once the aircraft takes off, the opportunity to sell a seat is lost Also the Vietnam’s Government control in the air fare via fare cap can cause the situation more problems There are many difficulties that airlines face so it is necessary to find a solution for Vietnam’s airlines The solution must solve the current problem: “How to trade off between the passenger’s demand and airline profit to keep the business on right way and development.” Following the world trend, Vietnam applied the low cost airline model in Vietnam market since May 2005, the first was Jetstar Pacific Airline which came from the full service airlines- Pacific Airlines Jetstar Pacific Airlines is a joint venture company between Vietnam Airlines, Qantas group from Australia and some individuals LCC model in Vietnam have the similar pricing and cost structures to the European and North American LCC (Goh, 2005) including some specifications: the same aircraft type, fast turn-around times, point - to - point services from main base, offering low fare in exchange for no extra services as compared to traditional airline offering free in-flight meals, beverages and in-flight entertainment but passengers can purchase these items separately if they choose to Passengers are encouraged to use online ticket booking and electronic ticket, no more paper ticket being used in cutting cost Innovative marketing strategies such as direct selling, call centers, eticketing, e-payments and bank and supermarket networks… Currently, there are two low cost airlines in Vietnam, Jetstar Pacific Airlines and Vietjet Air: Jetstar Pacific Airlines had a big start, becoming Vietnam’s first LCC in 2005, when the carrier (formerly known as Pacific Airlines) was rebranded and adopted the low-cost model following investment from Qantas, operating four domestic routes and 15 daily round trip frequencies, based on schedules from Jetstar’s website Jestar Pacific has been focusing on fleet renewal rather than expansion but is planning to resume expansion in 2013, ending a hiatus of four years in which growth was paused due partially to internal uncertainty The carrier began a more promising new period earlier this year after a 70% stake was transferred to Vietnam Airlines, (which previously had been looking at launching its own LCC subsidiary); Qantas owns the remaining 30% stake in Jetstar Pacific Jetstar Pacific for now is only planning to add two frequencies for the remainder of this year (both of which will take effect in latter half of Oct-2012),
