To investigate air passengers’ willingness to use intelligent facilities in airports, a total of 570 passengers were surveyed through three rounds of questionnaires combined with a technology acceptance model, and structural equation modeling was conducted on the sample data using statistical analysis software SPSS and AMOS, and the mediating effects of variables and the moderating effects of passenger attributes on the relationships of variables were verified. The results show that available awareness, perceived barriers to use, perceived health safety and security, and hedonic motivation are significantly related to passengers‘ perceived ease of use and perceived usefulness, and significantly influenced technology use intention through their mediating effects; social influence and technology use habits are relatively insignificant influencing factors; The degree of influence of all the above six factors on the willingness to use for those with low education, low income, and less frequent air travel is significant, the willingness to use for those who are young, have high education and more frequent air travel is strongly correlated with technology use habits, and the strong sensitivity factor for the elderly group is perceived health safety and security.
