Not all air cargo flies on dedicated freighters
Passenger aircraft routinely carry freight in the lower holds beneath the cabin. On routes with strong passenger schedules, that belly capacity can move substantial cargo without operating a separate freighter.
Dedicated freighters handle volume and unusual loads
Cargo aircraft can accept pallets, containers and shipments that are too large or impractical for passenger holds. Main-deck loading doors and reinforced floors support specialized freight operations.
Speed justifies the higher cost
Air freight is expensive per kilogram compared with ocean shipping, so it is used selectively. A grounded factory awaiting one critical component may value a one-day delivery far more than the transport price.
Airports function as logistics hubs
Cargo terminals consolidate shipments, build pallets, screen freight and transfer it between aircraft and trucks. Major integrator hubs are designed around overnight sorting so parcels can reach another region by morning.
Customs and documentation are part of the journey
International freight cannot simply be unloaded and driven away. Declarations, security data, dangerous-goods rules and import procedures can determine how quickly cargo actually reaches the consignee.
Temperature and handling requirements vary by product
Pharmaceuticals, animals, fresh food and hazardous materials all need specialized processes. Air cargo is therefore not one homogeneous business but a collection of tightly controlled supply chains.
