Recent studies have focused on understanding the public's perceptions of risk with respect to general reuse projects (Dolnicar et al., 2011; Toze, 2006; Bagget et al., 2006). These studies have shown varying attitudes toward water reuse and are necessary to assess the public's risk perception and acceptance of water reuse before implementing it. To date, no studies have examined passenger's attitudes toward the water reuse concepts at airports. 404 participants from India and the USA answered questions related to their attitudes toward various types of water reuse at airports. The results demonstrate that there are differences between cultures with respect to attitudes toward water reuse, and attitudes become more negative as degree of contact increases. Furthermore, the results indicate that there is a high correlation between participant scores from the commitment to environmental sustainability attitude scale and the attitude scores regarding type of water use
