Air transportation is generally urgent goods. If road transportation cannot meet the time limit required by the customer, the customer will choose air transportation. Air transportation is fast and safe. Punctual and ultra-high efficiency has won a considerable market, greatly shortened the delivery time, and played a great role in accelerating the capital turnover and circulation of the logistics supply chain. Major airlines have invested in a large number of flights to share the cake of freight. However, the cost of air transportation is higher than that of sea transportation.
