What do you get when you cross eBay, Priceline, and crowdsourcing? A recently re-launched Denver-based airfare site called FlyinAway.com. The membership-based model ($7.99 per month, $79.99 per year) asks users to vote for routes they’d like to fly—say, Denver to Atlanta. Once there’s enough interest in a proposed route, it goes to auction, at which point members can bid on the flight, eBay-style. If you’re the highest bidder, you can purchase up to four seats on that flight at the price of your winning bid. The startup works with all major airlines and domestic airports—but it doesn’t guarantee your preferred airline or flight times. Still, the company says, travelers can save up to 65 percent. “We wanted to turn the industry on its head,” says Andrew Cole, FlyinAway’s chief communications officer, “and give control to the traveler.”
