In order for goods to make their way safely into the skies, there are packing and fastening rules that must be followed.
Excerpt from the IATA:
The contents of each shipment must be responsibly packed so as to withstand all conditions ordinarily associated with transport and, where necessary, adhere to the conditions in the IATA’s dangerous goods regulations.
To that end, Cargo Handling Billund Airport has prepared a guide for safe air cargo transportation.
