6. Airbus A340-300 – $600 million

Private jets can be expensive in and of themselves, but when you’re buying a multi-million dollar jet why not spend hundreds of millions of dollars on decorating the interior of the plane as well? That’s exactly what Russian billionaire Alisher Usmanov did: the Airbus A340-300 itself cost $238 million, but after the luxury remodelling of the inside, it’s estimated that the jet cost around $600 million.

This super jet can carry 375 passengers and fly for 9000 miles at a time. The billionaire named his jet Bourkhan after his father, Bourkhan, a lovely partner for Usmanov’s multimillion dollar yacht which he named after his mother, Dilbar.
