Most people want to fly aboard a private jet and not even know exactly why. It is not because the why is mysterious, it is just that the reasons are numerous and people have not sat down to figure it out. The following are a few of the categories why one would want to fly aboard a private jet.
Custom Flights. A flight aboard a private jet is just like having a limousine for the air. It is all about the passengers. The passengers get to decide when the flight takes off, where it goes, who is on-board, any stops in between, etc. Even the refreshments or meals are made-to-order.
Luxury. Private aircraft are created to serve people who are accredited to the best the world has to offer. This includes the rich, the powerful, and the well-known. There are luxury appointments like real wood interiors and supple wide leather seats. They will have any number of electronics for both business and entertainment. These are just standard amenities, some rooms have bedrooms, conference rooms, or full bathrooms with showers.
Passengers. As mentioned before when one heads out on a flight he or she gets to decide who is on-board. One can travel solo or only with the people they want to fly with. They can also decide to bring on-board pets if they wish. The luggage is also assured to arrive with the passenger, it can even travel in the main cabin if they wish.
Privacy. Where one goes, who they go with, when they leave, the route, is all held privately. This could be very important to people who are security conscious. Private jets get to where they are going the fastest, so VIP's are less exposed while traveling. Plus, private aircraft have ten times the airports to choose from as opposed to the commercial carriers. Those smaller airports just add to the security and privacy of private aviation.
These are just a few categories. Any one of which could provide numerous reasons why one would want to travel on a private jet.
