For the first class crowd, a private jet is the ultimate upgrade. But buying or chartering is too expensive for all but a few. So how do you get to fly on a business jet for business-class prices?
Empty legs generally are available on rather short notice and often are best found when you can fly at times and in directions that few others find attractive. For example, the day of the Super Bowl, there may be many empty leg flights into the host city that will pick up customers after the game. The day before and the day after the game-not likely.
