In order to quickly resume flight delays at hub airports, delays in large-scale flights due to delays in hub airports have been reduced. Based on the joint transportation of aviation and high-speed railways, with the goal of minimizing recovery costs, a model for delay recovery of large-area flights at hub airports was established, and cancellation of short-haul flights or replacement of flights by high-speed rail transport was confirmed, and flights were resumed in real time. Using MATLAB to calculate the flight data of Shanghai Hongqiao International Airport, the results show that the high-speed railway alternative model reduces the recovery cost by 15% and saves recovery time by 30 minutes compared with the flight ground delay, flight cancellation, etc. The verification of the model recovery hub airport's large area flight delay is feasible and effective.
