It is arguable that the distinguishing feature between flying commercial and flying private is the time you can save. There is a laundry list of places to wait when you fly commercial: traffic getting to the airport, check-in and luggage check, security lines, at the gate (both off and on the plane), on the tarmac, deplaning, baggage claim, and getting through traffic to leave the airport. These can all be significantly reduced by flying private - research even shows it!
According to a study conducted by Jet Advisors, flying private saves time. They found that a firm could save a staggering 22.5 work days and 24 road nights every year per person if they flew private instead of commercial. That's an average of 7.5 hours saved per trip!
You won't have to waste you time sitting around and stressing about making connecting flights either. More often than not, you'll be on a direct flight with a car awaiting your arrival to take you to your final destination.
Plus, with recent improvements in technology and the expanding scope of wireless internet, work can be completed both on the ground and at cruising altitudes. This gives you the opportunity to be just as efficient as your private jet - that is, if you can keep up.
