Meet the 'homeless man' who flies the world first class
[1]  For the last year and a half, Ben Schlappig has been
essentially homeless. The 25-year-old American has ______
fixed address, ______ the keys to his own front door. Why
bother paying rent, he figured, when a bed was only ever a
[5] first class ticket away?

professional traveler with an almost obsessive attention to

credit card reward points, to zoom around the globe for a
[10] fraction of the cost.

Schlappig says he's never flown economy on an international
flight.
