{{Main| Air cargo}}
Air cargo refers to any goods shipped by air, whereas air freight refers specifically to goods transported in the cargo hold of a dedicated cargo plane.<ref>{{cite web|title=Air cargo VS. Air freight|url=https://an.aero/air-cargo-vs-air-freight-the-usage-in-the-shipping-industry|website=AN Aviation Servies}}</ref> Aircraft were first used to carry [[Airmail|mail as cargo]] in 1911. Eventually manufacturers started designing aircraft for other types of freight as well.

There are many commercial aircraft suitable for carrying cargo such as the [[Boeing 747]] and the more prominent [[An-124|An‑124]], which was purposely built for easy conversion into a [[cargo aircraft]]. Such large aircraft employ standardized quick-loading containers known as [[unit load device]]s (ULDs), comparable to [[Intermodal container|ISO containers]] on cargo ships. ULDs can be stowed in the lower decks (front and rear) of several [[wide-body aircraft]],<ref>In an all-freight configuration also on their main deck, but this is less common.</ref> and on the main deck of some [[narrow-body aircraft|narrow-bodies]]. Some dedicated cargo planes have a large opening front for loading.

Air freight shipments are very similar to [[Less-than-truckload shipping|LTL shipments]] in terms of size and packaging requirements. However, air freight or air cargo shipments typically need to move at much faster speeds than {{cvt|800|km|mi|0|disp=or}} per hour. While shipments move faster than standard LTL, air shipments do not always actually move by air. Air shipments may be booked directly with the carriers, through brokers or with [[online marketplace]] services. In the US, there are certain restrictions on cargo moving via air freight on passenger aircraft, most notably the transport of rechargeable lithium-ion battery shipments. 

Shippers in the US must be approved and be "known" in the Known Shipper Management System before their shipments can be tendered on passenger aircraft.
