ABSTRACT Title of Document: The Impact of Airline and Customer Characteristics on Airline and Airport Choice Woohyun Cho, Ph.D. Candidate, 2012 Directed By: Professor Robert J. Windle, Ph.D. Professor Martin E. Dresner, Ph.D. Robert H. Smith School of Business University of Maryland, College Park The customer choice of a particular air flight is composed of two choice decisions in a multi airport region. The customer chooses the airline and the airport that best meets their needs. This dissertation is composed of two essays. The first essay examines the airline choice decision and the second essay investigates the airport choice decision. In the first essay the focus is the impact of airline operational quality among airline characteristics. This may include nonstop flight services, service frequency, on-time operations, etc. These factors contribute to the overall utility of airline service. Improvements in operational quality can lead to increases in reliability and convenience. As a result customers will choose airlines that offer higher levels of operational quality. Particularly, some customers are more sensitive to operational quality based on their unique characteristics and tend to have stronger preference for the airlines that provide higher levels of operational quality. This essay examines the following three issues; (1) the impact of operational quality on customer’s choice of airline, (2) the moderating role of operations exposure (i.e., the extent to which customers are exposed to service operations) on customer choice, and (3) the moderating effect of customer characteristics on operational quality. The second essay looks at the impact of Low Cost Carrier (LCC) presence at airports and focuses on the following issues: (1) the impact of LCC presence on a route (after controlling for the impact of fares and service frequencies) on a customer’s choice of airport, (2) the moderating effect of customer demographic characteristics on airline characteristics, and (3) the moderating role of the customer’s geographical location on a customer’s choice of airport. Both of these essays will utilize survey data collected from the customers departing from the three airports in the Washington Metropolitan Area. This data includes customers’ choice of airline and airport along with extensive information on each customer including trip related information and demographic information. The Impact of Airline and Customer Characteristics on Airline and Airport Choice By Woohyun Cho Dissertation submitted to the Faculty of the Graduate School of the University of Maryland, College Park, in partial fulfillment of the requirements for the degree of Philosophical Doctor 2012 Advisory Committee: Professor Robert J. Windle, Co-chair Professor Martin E. Dresner, Co-chair Professor Thomas M. Corsi Professor Yan Dong Professor Paul M. Schonfeld © Copyright by Woohyun Cho 2012 Dedication To God: Without the strength, wisdom, and grace bestowed upon me by God, this dissertation would not have been possible. ii Acknowledgements The writing of this dissertation has been the most significant challenges I have ever had to face in my doctoral program. I would never have been able to finish my dissertation without the guidance of my advisors, my committee members, help from staff, friends, and support from my family and wife. I would like to express my deepest gratitude to my advisors, Bob Windle and Martin Dresner, for their excellent guidance, caring and patience during the program. I was extraordinarily fortunate in having both not only as academic advisors but also as great teachers and mentors who provided invaluable advices in every one of the hundred meetings we had, resulting in fruitful learning processes. I would also like to thank the professors, Tom Corsi, Curt Grim and Phil Evers for creating and handing down a great learning atmosphere throughout the LBPP Department at the Robert H. Smith School of Business. What they taught me ultimately shaped and contributed to all my research (particularly, thank you, Tom for driving me home when needed). Special thanks go to Yan, who provided tips and encouraged me in every situation. I would like to thank Dr. Schonfeld from the A. James Clark School of Engineering for kindly agreeing to serve on the dean’s representative committee member and generously sharing his expertise and thoughts. My research would not have been possible without help and support from Diane Fox and Justina Blanco. Without them, this program would not be as smooth as it is now. Many thanks go to all my doctoral student colleagues who were willing to help and to give their best suggestions as good friends. It would have never been an enjoyable program without them. Thank you, John, Dina and Fisher, for your encouragement. I will not forget the time I spent with my church members in faith, which kept reminding me of how thankful I was for being and why I was in the program. Last but not least, my deepest thanks with all my heart are saved for my parents, my parents in law and my kids (Yehum and Yewon). They were always supporting me with their prayers. Finally, I would like to thank my wife, Kyounghye. She was always there standing by me through the good times and bad times, travelling a life journey together as my friend. iii Table of Contents Dedication
