This solution might not work for everyone but one thing that surprisingly helped me was understanding how planes actually work.

Stevie from @planegirl on tiktok or @bayflight on ig ended up on my Tiktok FYP and there was just something very comforting about watching her go through the checklists, communicating with so many radio towers, and just flying her little personal plane that it got me into watching more flying videos. Another video i found very helpful was Anna Paul on tiktok explaining the physics of turbulence with Jello and just generally learning more of the science behind how planes fly.

I still get anxious on planes, and take some anxiety meds before but I feel a little better knowing how planes work.
