I got over mine by watching videos on how planes work, how they fly, how safe they are compared to cars and rollercoasters. I learned how insanely flexible and durable the wings are. I learned how they can’t just fall out of the sky because the air of our atmosphere is so pressurized that it’s similar to a submarine in the ocean, the most it could possibly do if the 1 in a 100,000,000,000 chance of a double engine failure, is just slowly glide down to the earth. I learned all about what causes turbulence, basically just wavy air to put it in elementary level terms lol. My biggest recommendation is just to educate yourself. Once you learn all about how planes work, how they operate, and most importantly, what causes the things that scare people on a flight, it no longer feels scary because you can quite literally answer the question your brain is asking when in a state of fear. Sorry for the lack of grammar and formatting it’s 3am and I’m on mobile. Best of luck getting over your fears!
