This. Anti anxiety medications work. Save your self-behavior-altering energy for things that matter more in life. Xanax will also help you sleep on flights.
I also have a crippling fear of flying but i will fly in 10 days so i did a "test run" with Lorazepam which helped my step-dad who didn't fly for 20 years and is now anxiety free during flights with no medication needed. I was watching flight videos on youtube and found myself giggling in euphoria.
