The rapid development of AI is transforming purchasing behavior in the tourism market. This study examines the relationship between age and tourists’ choice of purchase channels, frequency of AI use, perceived barriers, and factors increasing willingness to adopt AI-based tools. The research was conducted in Poland in 2024–2025 using a diagnostic survey (N = 1025). Statistical methods included the chi-square test, Cramer’s V, and discriminant analysis. The results reveal significant intergenerational differences. Younger respondents more frequently use mobile applications and digital platforms, whereas older consumers prefer traditional channels and direct human contact. The intensity of AI use decreases with age. Older groups report higher concerns about misinformation, privacy, and lack of interpersonal interaction. At the same time, transparency of AI systems and access to human support increase acceptance, particularly among older users. The findings contribute to smart tourism research and support the need for segmented AI implementation strategies.
