I know you're kidding around here, but all kidding aside, whether your net worth is $14M or $50M, you can't afford a jet. (I mean, nominally speaking, you can front the sticker price -- but you'll get eaten alive on fuel and maintenance over the jet's useful lifespan, and the jet as an asset is depreciating all the while.)
I say this almost as a reflex. I used to work in talent management many lifetimes ago, and I'd actually find myself having this talk with people in this specific situation. Explaining to someone who just made $10M on a single movie that s/he can't afford a jet is a surreal experience. Sorry for the tangent!
