The ultimate superyacht with wings, the Boeing BBJ 777-9 is the longest, roomiest, and priciest new private jet available for order. A veritable palace above the clouds, the 75-passenger leviathan is even longer than the already supersized 777-8. It has the same top speed, and though its range isn't quite as great, it nonetheless comes in at a breathtaking 11,330 nautical miles (20,985km).

The sky's the limit in terms of customisation. Buyers can really go to town packing the plane with the most incredible amenities and luxuries money can buy. The aircraft has a base price of $454 million (£332m), but with customisation, the final bill can easily surpass half a billion dollars.
