patience and guidance, I would not have reached my final results Secondly, thanks to respectful lecturers of University of Economics Ho Chi Minh City and all members of eMBA class course 19 have supported me in enhancing knowledge during the master of business administration course Thirdly, I would like to thank the participants who had taken their precious time to answer the questionnaires This thesis would not have been feasible without their valuable and honest feedback Last but not least, special thanks and love to my husband who is also my eMBA classmate, Nguyen Van Thanh, for his useful discussions and advices while implementing this thesis At the same time, deepest thanks to other eMBA classmates and my two close friends for their voluntary and enthusiastic supports and kindnesses Pham Vo Thanh Diep Ho Chi Minh City, October 2012 TIEU LUAN MOI download : skknchat@gmail.com II COMMITMENT I would like to commit that this study, “The mediating role of relationship quality in the relation between relationship benefits and word of mouth: a case study of Vietnamese airlines ticket service”, has been implemented based on my independent and serious studies and scientific researches The data were collected from reality and they had credible origins The thesis supported the rule of antiplagiarism Pham Vo Thanh Diep TIEU LUAN MOI download : skknchat@gmail.com
