Air freight or air cargo refers to goods that are transported by plane. Most often, these goods are valuable and/or time-sensitive shipments that are sent worldwide by express freight.
As a rule, this is a more expensive way to ship goods, and freight costs depend on the volume and weight of the goods. Usually freight is invoiced based on volume weight. For this reason, it is very important for shippers and air freight companies to have accurate knowledge of volume and weight.
Moreover, this data is relevant for flight safety.
