Layers, Layers, LayersPashminas, shawls, wraps, cardigans, sweatshirts, vests, and light jackets are perfect. You can even fold or roll soft items, like cotton jackets, and use them as makeshift pillows during flight. Plus, the more layers you pile on your body, the less you need to pack in your luggage.
So, yes you can survive. Stowing away in the wheel well is almost certain death. Some cargo holds are pressurized and some are not. people have survived in non-pressurized holds and people have died in non-pressurized holds.
The first question that arises is whether a commercial cargo plane is pressurised. If asked in one word, it's yes. Most commercial air freighters predominantly use pressurised fleets. The majority of cargo that is shipped requires temperature and pressure controls.
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).
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.
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.
When we fly with only 2 pilots, we are allowed to take controlled rest if we really feel the need to. One pilot then sleeps for a short while in the pilot seat, while the other pilot takes control of the flight and communication. And if we fly with more than 2 pilots we have time to rest in the bunk.
Typically, cargo fire suppression systems have an initial high-rate knockdown discharge, followed by a low-rate metered discharge of Halon 1301, designed to keep the fire suppressed for continued safe flight and landing at the nearest suitable airport. Halon can be discharged into the forward or aft cargo compartment.
By wearing long trousers, passengers will avoid direct contact with the seat and will be more protected against germs on the plane. The flight attendant also compared leaning your head on the window with wearing shorts. He explained: 'Do not fall asleep or lean your head on the window.
 Wear layersEven though the temperatures may be warm at your destination, on the plane that's a different story and layers are key to dealing with fluctuations in temperature. A light jacket, sweater, wrap, or kimono won't take up much room but will keep you warm when the in-flight temperature drops.
Pajamas. We're all for being comfortable on a flight, but since you do have to be out in public, it's best not to wear pajamas to the airport and onto the plane. Instead, wear loose-fitting, comfortable pants with an elastic band, said Susan Fogwell, a former flight attendant with 22 years of experience.
Your pet dog or cat is secured inside their IATA-compliant crate before boarding the flight. Most airlines ensure your pet boards and disembarks the aircraft on priority. The cargo hold has a special area for pets, and your pet's crate is secured in the plane in its designated space.
