When will SF use the plane?

Time is urgent, the weight and volume are large, and special items are needed. SF's use of aircraft includes:

1, time is pressing. If SF needs to deliver the goods to the destination in the shortest time, it will choose air transportation. Because the plane is fast, it can reach its destination on time.

2, the weight and volume are relatively large, which is more suitable for transporting goods with relatively large weight or volume by plane. Because in air transportation, the load of aircraft is much larger than other means of transportation, and a large number of goods can be delivered to their destinations conveniently and quickly.

3, special cargo requirements, some goods have special properties or requirements, such as fresh and fragile. By air, these goods can be transported to their destination faster and the damage of the goods in transit can be reduced.
