Yes, most airplane cargo holds are pressurized. This means that the air pressure in the cargo hold is the same as the air pressure in the passenger cabin. This is important for two reasons: To prevent cargo from expanding or contracting.

According to estimates released by the Department of Transportation, less than 1 in 10,000 animals were injured, lost, or killed from flying. That said, the general safety of flying your pet as cargo doesn't discount the gravity of the fact that animals are sometimes harmed by flying in the cargo hold.
Cargo travel is stressful for any pet, young or old. Senior pets, pets prone to anxiety, or those in general poor health are at increased risk of heart failure during travel. Please consult your vet before travel to ensure your dog or cat has a clean bill of health and is an appropriate candidate for cargo travel.
The cargo hold is climate-controlled and will not be colder or hotter than cabin temperature. A pet-friendly airline will make sure your pet is comfortable at all times. Many airlines have temperature embargoes to deal with extreme temperatures.
Doing your pre-start scan, the temperature controller for the cargo holds is usually just left at 12 o'clock. That should result in a zone temperature of about 15C.
Mechanical ventilation systems actively blow air across or through the cargo hold to remove hazardous gases or vapours. If the cargo is prone to self-heating in the presence of moisture, mechanical ventilation should be applied in specific circumstances only.
The temperature in an airliner's cargo hold can vary depending on the airline and the type of aircraft. Generally, it is kept between 10-15 degrees Celsius (50-59 Fahrenheit). However, some airlines may keep their cargo holds at a higher or lower temperature to ensure that certain items are stored safely.
The general rule is that planes should have cabin pressurization when they go above 10,000 to 14,000 feet. Can a pilot depressurize a cabin? Most aircraft cabins are pressurized to an altitude of 8,000 feet, called cabin altitude.
Ventilation may be needed to ensure that there is a sufficient oxygen supply for safe personnel entry into the cargo space. Similarly, ventilation may be needed to remove poisonous and flammable gases which could give rise to a dangerous situation.
As long as the inside of the aircraft is kept warm enough, planes can take off and land in temperatures as low as minus 67 degrees Fahrenheit. It's often not much warmer than that outside your window at altitude. If you've ever put your hand on the wall or window when you're flying, you'll note that it's cold, sure.
How exactly does the airline treat a pet in the cargo hold? Be very careful about choosing your airline! Cats, dogs and other small animals are known to get lost and even killed via airline travel. Some airlines are more notorious than others.
According to the American Veterinary Medical Association (AVMA), sedatives should not be dispensed for transporting animals except in rare circumstances. Cargo holds in aircraft are pressurized at high altitudes, and the effects of sedation at 8,000 feet or higher are poorly understood.
This valve controls the cabin pressure and also acts as a safety relief valve, in addition to other safety relief valves. If the automatic pressure controllers fail, the pilot can manually control the cabin pressure valve, according to the backup emergency procedure checklist.
The Cabin Altitude of a pressurised aircraft is normally maintained at and altitude of 8,000 ft or less as a compromise between the physiological needs of the crew and passengers and the structural limitations of the aircraft. At 8,000 ft the use of supplemental oxygen is not required.
