Here's where some of the biggest player in the rent-a-jet world can (and can't) take you. NetJets. What it does: Sells fractional ownership shares starting at $406,250 for 1/16th interest in a small jet. Pluses: Ideal for those who fly at least 50 hours per year often with short notice or during peak demand periods.ypically, prices for private jet charters of more than a few days can cost double the time you're actually in the air because the plane won't wait for your return flight. That results in pilots flying empty or deadheading 40 percent of the time.
