Summary	With the rapid development of information and communication technology (ICT), airports and airlines are trying to provide passengers with the personalized boarding experience using mobile devices and automation equipment. Therefore, the deeper the understanding of the passengers' boarding behavior by the airport or airline, the more they can provide the most appropriate information and personalized services that passengers need. In addition, boarding passengers are increasingly paying attention to the waiting time of unnecessary waste, and begin to pursue the acquisition of real-time information and self-control of the boarding process.        Based on the above reasons, this study is aim to explore the risk attitude and ambiguity attitude of airport boarding passengers due to the lack of important information on travel time uncertainty. Most of the previous studies only considered boarding passengers' choice of airport arrival behaviors, ignoring the possible link between the airport arrival behavior and the activity arrangement in the terminal. The main contribution of this study is to consider the risk attitude and ambiguity attitude of air passengers on the travel time uncertainty, and to obtain the composition and characteristics of air passengers with different time preferences. The concept of the trip chain is used to link the airport arrival behavior and terminal activities of boarding passengers. Based on the time and space trajectory data of the boarding passengers in the terminal activities, the analysis of passengers' time preference and terminal activities time allocation is carried out to avoid the passengers' perception errors in recalling individual behaviors.        This study used Taipei Songshan Airport and Taiwan Taoyuan International Airport as research samples. First, a one-on-one interview was conducted on passengers using questionnaires and scenario design. Then, the risk attitude model and the ambiguity attitude model of the air passengers with travel time uncertainty are built by using the Ordered probit model and the α-maxmin model. Finally, minutes before the departure time of the flight is used as the explanatory variable, and the regression analysis model is used to analyze the impact of time allocation of mandatory activities in the terminal and the degree of risk aversion and the degree of ambiguity pessimism that obtained from the risk attitude model and the ambiguity attitude model.
