A unit load device (ULD, is a pallet or container used to load luggage, freight, and mail onto wide-body aircraft and specific narrow-body aircrafts. This allows a large quantity of cargo to be bundled into a single unit. Since this leads to fewer units to load, it saves ground crews time and effort, helps to prevent delayed flights and thus enhances the speed and efficiency of freight forwarding services.

ULDs come in two forms: pallets and containers. ULD pallets are rugged sheets of aluminum with rims designed to lock onto cargo net lugs. ULD containers, also known as cans and pods, are closed containers made of aluminum or combination of aluminum (frame) and Lexan (walls). Depending on the nature of the goods to be transported, these may have built-in refrigeration units.

Below you will find specifications and sizes for different Air Freight Containers.
