It's safe. promise!
I am not a pilot.
I don't fly often
I also do not like flying to much.
But what I do know is that flying is officially the safest way of transport.
There are more than 3 times more deaths and injuries on the roads than in airplanes.
I once was on a flight home from America one and there was a lot of turbulence.
I found it really helped to have a quick chat to the pilot he told me everything was fine and that it's nothing to worry about.
If you done like turbulence ask to sit in the middle of the plane ( where the wing is) it's not as noticeable there.
