Turbulence on jet passenger planes

Of course private small jets are the least safe in turbulence because they tend to be much smaller than passenger jets. Generally speaking the larger the jet you are on the safer you likely will be in severe turbulence: IF:

You are religious about keeping your seat belt on during all flights (except when you absolutely have to go to the bathroom). Other wise on long flights especially 3 to 6 to 11 hours long especially over oceans or mountains you might get a concussion from hitting your head on the ceiling of a passenger plane.

Or worse, suddenly being slammed against the ceiling (extreme downdraft) and then going into an extreme updraft where you are thrown against the backs of seats or other people on the plane where everyone gets injured.

This is a very serious thing by the way and most likely during storms over major oceans like the Pacific or Atlantic Oceans but also over higher mountain ranges during storms.

But, what is also happening more now is extreme temperature changes in air masses which cannot easily be understood by radar and people viewing the radar. So, the first Jet passenger plane to hit such a bad spot might have many injuries or even deaths. But, later flights might be okay because they will here about it from air traffic controllers and slow down or avoid that area where this happened entirely.

But, the first plane to hit turbulence in any area is sort of like the "Canary in the Coal mine" in that it tells all the other jets not to go through there at all or at that altitude.

So, if you remember to keep your seat belt on at all times it is more easy to survive any flight you might get on. And ONLY go to the bathroom in a real emergency so you spend as little time out of your seat as possible.

This is how it is easiest to stay alive and uninjured during a jet passenger flight to anywhere around the world.

Turbulence is becoming more and more normal on flights every where every day now because the weather is becoming more and more extreme around the world caused by Global climate changes.

HOWEVER,

You don't need to be passing out from your seat belt like you might tighten it up for takeoff. There can be 4 to 5 inches play in your seat belt and still keep you in your seat enough so you don't get injured when flying 2 to 6 to 11 hours somewhere. You need a seat belt not a straight jacket to stay safe and alive on flights. Then you can tighten it up if you want for landing.
