In recent years, China’s economy has developed rapidly and the people’s living standards have continued to improve. A high end means of transportation, airplanes, is favored and accepted by more and more people with its advantages of comfort, speed, and safety. Accompanying it is the increase in pressure on passenger transportation in the aviation industry. The development of Chinas civil aviation industry is relatively late and relatively immature. It has only ushered in a development frenzy after the reform and opening up. Therefore, the method of predicting airport passenger throughput is also imperfect. The outdated forecasting method cannot predict the situation of the airport well, so it is very important to seek a more scientific, more complete and systematic forecasting method of airport passenger throughput. This article has conducted a certain review and research on the prediction methods of airport passenger throughput, and hopes to have further research in this aspect.
