Hey, yes my flying anxiety got so bad last year I vomited twice before we left the house for the airport! Since then I’ve managed to get it under control, however I’ll never enjoy it.
I don’t have kids so these might not be helpful if you have little ones in tow, but
Earphones are your friend. The less you can hear, the better, in my experience. Have a podcast playing from the moment you get on the plane.
Take a book you are really into. Again, if you have small children, this might not be possible.
An eye mask. Ignorance is bliss is the theme here :)
Tell the cabin crew that you are nervous, they are brilliant.
Remind yourself that you’re safer up there, where everyone’s been through security and the plane has been checked over and over again, than you are down here.
Take snacks and get a cuppa when they offer, this takes up time and distracts you.
If you can afford it, buy extra leg room. Get an aisle seat if you are claustrophobic.
