Bf is flying😔

I’ve never been on a plane before but I’m terrified of flying and I found out my bf and his cousin are flying to Orlando in a couple weeks and I’m freaking out about all the things that could possibly happen since there going alone there both 18 I just overthink eveything as it is😔 what’s the odds of a plane crash? Is it highly likely/unlikely? If anyone has any advice..please feel free to comment
