charge by volume or weight?
Most personal effects travelling by Air cargo are charged by weight. However, some items are very large in size but light in actual weight eg: surfboards, surf ski’s etc. This type of item is called ‘volumetric’ and is charged by airlines for the space taken in the aircraft. Sea cargo is charged by volume, not weight, although it generally starts to become economical when the size of your shipment approaches 1 cubic metre or 8 shipping cartons (Removalist Boxes 42x44x61cm).
