Editorials Jet Set Jettisoned January 15, 1998 Share 1 -- How does one attain mile-high-club status? A variety of ways, according to Diana Benson, a former flight attendant for MGM Grand Air. Benson penned a tell-all book called "The Mile-High Club," giving readers the lowdown on the high jinks of celebrity passengers who flew on the upscale carrier. MGM Grand Air, the brainchild of Kirk Kerkorian, transported the rich and famous from coast to coast from 1987 until it ceased operations in 1995. Readers will find anecdotes about Julia Roberts, Michael Jackson, Madonna, Lauren Bacall, Harrison Ford, Whoopi Goldberg, Pat Riley and many others. Readers can find out which diva tried to sneak cigarettes in the lavatory, which one had a $25,000 couch custom made for the plane, and other dish, some of it quite unseemly (and, to this browser, at least, of questionable veracity). Readers who want to take a peek into the ultimate first class cabin can check out Benson's site on the Web at www.mgmstew.com. But readers should fasten their seat belts, because, in the words of the immortal Margo Channing, "It's going to be a bumpy ride."
