In order to solve the problem of the new airport passenger throughput forecast, a new forecast model which based on airport groups is put forward in this paper. In this model, the competition ability of airports and the important factors which affect passengers travel choice are introduced into it. Then by constructing passenger utility function, the new regional airport passenger throughput can be forecasted. This model will increase the accuracy of the new regional airport passenger throughput forecast. Empirical results show that the method is applicable and effective.
