One cubic meter for regular air transportation is equal to 167KG, and one cubic meter for international express delivery is equal to 200KG. The larger of the volumetric weight and gross weight, if the chargeable weight of the goods does not exceed 30KG, international express delivery will be more cost-effective under normal circumstances. If the cargo exceeds 30KG, you can compare it to regular air freight, and the price of air freight should be more favorable.

In addition, regular air freight is more flexible than express delivery. The customs declaration documents are relatively flexible, and express customs declaration is generally based on the export declaration invoice provided by the shipper. And this invoice must always accompany the goods to the destination port. Regular air freight customs declaration, as the shipper's invoice may not be random. If the invoice for foreign export customs declaration is inconsistent with the invoice for domestic import, some issues related to customs declaration can be flexibly resolved.

What are the international air transportation methods?

Air transportation mainly includes flight transportation, charter transportation, centralized consignment, and air express delivery services. The following is a brief introduction to each transportation method.

1. Flight transportation

A scheduled airline refers to an aircraft with a fixed departure time, route, and terminal of call. Usually a mixed passenger and cargo aircraft with a smaller cargo capacity and higher freight rates, but due to fixed flight schedules, it is beneficial for customers to arrange the transportation of fresh or urgently needed goods.

2. Charter transportation

Chartered carrier refers to the leasing of an entire aircraft by an airline to one or more charterers (referring to the shipper or air freight forwarding company) based on agreed conditions and rates, to transport goods from one or several air terminals to a designated destination. Charter flight transportation is suitable for the transportation of bulk goods, with lower rates than regular flights, but longer delivery times than regular flights.

3. Centralized consignment

Consolidation can be carried out by flight or charter flight, which refers to the air freight forwarding company consolidating several batches of separately shipped goods into one batch to be consigned to the airline, filling out a master waybill and delivering it to the same destination, and then entrusting local agents to distribute it to each actual consignee. This shipping method can reduce freight costs and is one of the main businesses of air freight agents.

4. Urgent delivery

Express delivery is currently the fastest way in air transportation, which is carried out in collaboration with departments and airlines specializing in this business to deliver urgent packages in the fastest possible way.

5. Material basis

The material foundation for achieving air transportation. Mainly including routes, airports, aircraft, and communication and navigation facilities. The route is a corridor style protected airspace established based on ground navigation facilities, which is the field of aircraft flight routes. Its delineation is based on a straight line connecting various ground navigation facilities as the centerline, and specifies the upper limit altitude, lower limit altitude, and width within the route range. Air traffic control should be implemented for aircraft flying within its range. An airport is an integral part of a civil airport and related service facilities, serving as a safe base for aircraft takeoff and landing, as well as a hub for passengers, cargo, and mail.
