Order a ticket plus companion ticket to London for every other day of the month. Sell the companion ticket on craigslist for $200 and ferry people you've never met to Europe.
That's an awful lot of strangers to make transatlantic flights with at 200 bucks a pop, and it would take quite a long time to recoup the multi-hundred-thousand dollar investment in the companion ticket. Hardly seems worth the time for somebody who can afford half a million for a couple of lifetime passes.
When bond broker Willard May of Round Rock, Texas, was forced into retirement after a run-in with federal securities regulators in the early 1990s, he turned to his trusty AAirpass to generate income. Using his companion ticket, he began shuttling a Dallas couple back and forth to Europe for $2,000 a month.
"For years, that was all the flying I did," said May, 81. "It's how I got the bills paid."
