Phil Ruffin

Phil Ruffin is involved in a diverse number of businesses, including gambling, real estate, and oil production. He lives in Las Vegas and is no stranger to the Forbes 400 List. In his 2008 appearance, the magazine estimated his net worth at $2.1 billion.

A private jet is the de rigueur mode of travel to spirit a billionaire from one luxurious locale to the next. However, Ruffin is no ordinary billionaire, so he spent $70 million on a Boeing 737 jumbo jet, then put an additional $15 million into renovating the interior, which he outfitted with leather seats, two full bedrooms, and a $1 million entertainment system.
