Boeing 747-8 VIP
Price: $295 million*

This jet, which has 4,786 square feet of cabin space, is the newest member of the 747 family and replaces the 747-400. Boeing has sold seven 747-8 VIPs since May 2006 and will start delivering them next year. While the interior is intended to look less like a plane and more like home, Boeing does not furnish the jets—customers must hire interior designers, which can easily add millions of dollars in additional cost, says Boeing spokesman Bernard Choi. He says the jet probably will not enter service until after 2012, because the interior has to be put in.
