In an increasingly globalized economy it’s important for the elitist of the elite to get around in a safe, reliable, and fast manner. Clearly the only option for fast travel these days is by airplane, but the world’s billionaires aren’t exactly flying economy class with the rest of us.

1. Gulfstream IV – $38 million

It’s no Boeing, but Tom Cruise’s tiny Gulfstream IV has made quite a name for itself. Coming in at $38 million, this plane isn’t known for its luxury and space, but it does have room for 19 passengers and is powered by two Rolls-Royce Tay 611-8 engines.

This plane is hygienic as well – every two minutes the air in the plane is refreshed so as to avoid the airborne illnesses that us mere mortals are privy to on commercial airlines.
