This conceptual paper proposes a new research agenda in travel risk research by understanding the role of affect. Extant scholarship tends to focus on travel risk perception or assessment as a cognitive psychological process. However, despite the phenomenal growth of the tourism industry globally, research related to travel risk perception remains stagnant with no significant breakthrough. Drawing on the existing empirical evidences in risk-related research, this paper asserts that affect plays a potent role in influencing travel risk perception – positive affect leads to more positive travel risk perception, vice versa. In this paper, existing empirical evidences and theories are presented to provide support for this proposition.
