The invention discloses a CC-MIDNN-based aircraft arrival time prediction method, and relates to the technical field of flight arrival time prediction, and the method comprises the steps: carrying out the preprocessing of flight data, carrying out the clustering analysis of the flight data through employing a K-means algorithm, taking a contour coefficient as an evaluation index of the clustering analysis, training sub-networks through employing the divided data, and carrying out the prediction of the arrival time of a flight. A Bayesian optimization algorithm is used to optimize network hyper-parameters, so that a network structure is automatically determined, and output results of each sub-network are integrated; according to the method, the idea of modular integration is introduced, a complex modeling task is decomposed by using a clustering mode, then the sub-networks are constructed by using the DNN based on Bayesian optimization to learn different sub-tasks, and the efficiency and accuracy of the model are improved by using different modules to process different sub-tasks in parallel.
