Abstract: “The purposes of this research were to measure and compare the service quality perceptions of Thai and foreign budget airlines that were affected by country image. Four hundred and twenty seven questionnaires were answered by customers in Bangkok. Statistical instruments such as mean, standard deviation, t-test, and One-Way-ANOVA with the significant level at 0.05 were selected to complete the process of data analysis. The results revealed that the highest service quality ranking was the airlines from the Thailand, Singapore, South Korea, Malaysia, Philippines, Indonesia and China respectively. However, the service quality of these airlines was not significantly different in hypothesis test. Also the study found that the service quality of the budget airlines for Thailand and foreign countries had no significant differences either.”
