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.

Is 737 cargo pressurized?
What is the difference between pressurized and unpressurized aircraft?
Unpressurized – These aircraft are typically piston powered and can't go very high, so do not even attempt to regulate the air pressure inside the fuselage. Pressurized – These aircraft do maintain pressurization in the fuselage, but it isn't constant beyond a certain point.
What is A350 pressurized to?
The low cabin altitudeBecause the fuselage is made from a carbon-fibre composite plastic rather than aluminium, the cabin can be pressurised more. Essentially that means that the cabin altitude is lower. On an Airbus A350, you can be flying at 35,000 to 40,000 feet, but the cabin will be at around 5,500 feet.
