The whole idea of having a private jet, besides the obvious privacy aspect, is that you get to have it decorated however you want, right? Maybe not, depending on exactly what features you're after. Any plane that wants to fly in U.S. airspace has the Federal Aviation Administration to comply with, and no matter how fancy you make it a plane just isn't any fun when it's stuck sitting on the ground.

On the bright side, many features can be modified or changed to where they're still enjoyable but don't break any laws -- like chandeliers are okay if they're retractable, and you can have all the heavy mahogany and big screen TVs you want as long as you're willing to trade off in terms of increased fuel and lower over-all capacity for things like passengers and cargo.

So what isn't okay, ever, on a plane? An open flame, which automatically rules out features like fireplaces and gas stoves.

But as long as you have a golden toilet, who cares.
