Since the COVID-19 pandemic, airlines worldwide have enforced strict travel restrictions, driving passengers to seek alternative transportations such as High-Speed Railway (HSR). Nevertheless, the current understanding of HSR travelers’ behavior is scarce. Moreover, despite the extensive application of the Theory of Planned Behavior (TPB) to explain and predict patrons and tourists’ behavior in the tourism and hospitality context, little research has employed this theory to examine HSR travelers’ processes in making travelling decisions. This study developed a research model by integrating perceived quality into the TPB and examined the relation between HSR passengers’ service quality and intention to travel in the future and the mediating effect of TPB attributes. It is found that perceived train service quality and perceived travel quality have a significant influence on the TPB attributes, which further influence HSR travelers’ travel intention. This study contributes practical implications to destinations and the travel industry that they might attract visitors by marketing the corresponding HSR train service quality and travel experience quality. This also provides recovery guidelines for the transportation and travel industry after the COVID-19 pandemic.

International volunteer tourism is an emerging and sustainable trend of the global tourism industry. In this study, we attempted to provide a clear comprehension of volunteer tourists’ mental health increase and pro-social intention formation. A survey method and quantitative approach were used. Our result from the structural analysis showed that hedonic and utilitarian performances, mental health, and volunteer tourism engagement had significant associations and that these relationships contributed to improving pro-social intention. In addition, results from the metric invariance assessment revealed that the volunteer tourism engagement and pro-social intention relation was under the significant influence of problem awareness and ascribed responsibility. Mental health and engagement acted as significant mediators. The comparative importance of volunteer tourism engagement was uncovered. Overall, our results provided a sufficient understanding of volunteer tourists’ pro-social decision-making process and behaviors.

Volunteer tourism is a vital formation of altruistic and sustainable tourism. This research is aimed to empirically find the relative importance of the motivation factors and the motivation realization factors for young tourists participating in the global volunteer tourism programs. The differences in the study variables across continents, gender, and frequency of participation were also scrutinized. A quantitative research approach that utilized the survey method was employed. The outcomes showed that personal development was the most vital motivator for global volunteer tourism. On the other hand, the young tourists felt that they most realized the factor of a new experience through their recent international volunteer tourism experience. The motivation factors and the motivation realization factors were consistent across the continents. Furthermore, the mean differences in the motivations, the motivations’ realization, satisfaction, and the behavioral intentions were revealed to be non-significant for the genders and the frequency of volunteer participation. By grasping the young volunteer tourists’ motivations and the experience evaluations, the volunteer programs can be advanced in consonance with their necessities and demands, which enhance the volunteer tourism experience.
