Choosing an airport that allows for multiple flights per day can significantly increase efficiency.  Ezhou Airport’s existing traffic rights and infrastructure enable a 757 to fly to Bangkok, unload, return, and make another trip within the same day.  This maximizes aircraft utilization and expedites cargo delivery.

In contrast, Kashgar might have limitations on flight frequency and ground handling capabilities.  Factors like the availability of cold storage facilities at the airport to prevent perishable goods from spoiling during ground time need to be assessed.

Therefore, the optimal solution often involves a multimodal approach.  In the case of transporting grapes, using refrigerated trucks to transport the grapes from Kashgar to Ezhou Airport, where the necessary infrastructure is readily available, proves to be more efficient.
