Is there oxygen in cargo hold?

The hold is pressurized. There is plenty of oxygen, but some airline cargo holds are not climate-controlled, Thompson said. During Sunday's flight from Charlotte to Washington, the Embraer E170 reached an altitude of 27,000 feet, according to FlightAware, an airline tracking website.

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.

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 cargo hold is pressurized and temperature controlled, with the temp usually at about 20 degrees colder than the cabin (at altitude).

Being trapped inside a baggage compartment during a flight is no picnic. The hold is pressurized. There is plenty of oxygen, but some airline cargo holds are not climate-controlled, Thompson said.

Undeniably, cargo is the more dangerous option for pet travel. The safest way for any animal to fly is in the cabin as carry-on luggage, provided that's an option. But only animals small enough to fit beneath the seat are allowed: A cat, a rabbit, or a Maltese is fine; a full-grown Labrador isn't.

You should have no concerns about temperatures in the cargo hold. According to a 1996 New York Times story, Federal Aviation Administration tests showed that temperatures inside pressurized luggage compartments ranged from 65 to 70 degrees, comparable to passenger compartments.

The primary problem is low oxygen, says Professor Frances Ashcroft, a physiologist at Oxford University. Low pressure would cause little more than discomfort in the ears and eyes, but the associated drop in oxygen levels makes people pass out if they do not put their oxygen masks on within about 15 seconds.

Are dogs in cargo treated like luggage? Dogs travel underneath the plane but in a separate climate-controlled and pressurized compartment, they breathe the same air the human passengers breathe. Cargo dogs are typically the last loaded on the plane and the first off to reduce exposure to inclement weather.

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 whole process of flying can be stressful for a dog, but those levels of stress can be greatly reduced with a few simple home comforts and reassurances. Ensuring your flight is a non-stop flight rather than one with changeovers can be a huge benefit to your dog, as can looking to travel at a suitable time.

The flight is far from the first to see a stowaway survive a perilous journey. In November, a 26-year-old man was found in a plane's landing gear compartment at Miami International Airport. Authorities said he had survived the 2-hour and 37-minute flight journey from Guatemala.

That being said, most flight crew will have considerably higher tolerance for turbulence than most passengers, and crews flying freighters are considerably more likely to just ignore some light turbulence than crews flying passengers (the boxes* neither shriek, nor write nasty letters to the airline).

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.

On airplanes, this can occur when pressurization and supplemental oxygen systems aren't working or during explosive and rapid depressurization, according to FAA guidelines.

According to the American Veterinary Medical Association (AVMA), sedating cats or dogs during air travel may increase the risk of heart and respiratory problems. Except in unusual circumstances, veterinarians should not dispense sedatives to transport animals.

Your pet will be in his crate for the entirety of the flight in a temperature-controlled portion of the cargo hold. While some pets simply sleep or rest until the plane lands, others panic or suffer from motion sickness.
