When it comes to private jets, there are some that are a cut above the rest.

These days, a select lucky few are taking luxury air travel to new heights with state-of-the-art ultra-long-range executive jets from manufacturers such as Gulfstream and Bombardier. And then there are those bold enough to convert commercial airliners into opulent flying palaces.

It's all very impressive.

Naturally, this list is fluid and subject to change — after all, Elon Musk might surprise us all one day with a pimped-out SpaceX Crew Dragon capsule mounted atop a Falcon Heavy rocket, or a company like Zunum Aero could give us an electric private jet.

But for now, at least, here are the seven most luxurious private jets in the world, according to Business Insider.
