9. CUSTOMIZED BOEING 747-400 (WORTH: $220 MILLION)
The customized Boeing 747 owned by Saudi Arabia’s Prince Al-Waleed bin Talal is another passenger plane turned private jet. This plane, which he bought in the early 2000s, was customized with two expansive bedrooms, a dining table that could sit 14 people, and of course, a throne right at the center of the aircraft. What’s a prince without his throne, right?
