Many are surprised to hear that the cargo hold in the belly of an airliner is pressurized. Conditioned air is directed from the cabin, so the air tends to be a little cooler by the time it reaches the cargo areas, which are also less insulated than the cabin. Cargo temperatures vary in our fleet. The Boeing 767 maintains its baggage hold above 7˚C, but the bulk area (where animals are carried) can be heated above 18˚C. Controlled temperature cargo bins are also available when temperature‑sensitive goods are being shipped.
