Flying on one of the major scheduled airlines, you're renting a seat from them (and maybe a little bit of space for some luggage).  With private aircraft charter, you're renting the entire aircraft.  Because it's your plane and not just your seat, you're not at the mercy of the other passangers when it comes to where you're going and when you leave.

With private aircraft charter services, you're typically flying in smaller private jets which allow you to leave and fly to much smaller airports.  This reduces the time you need to travel by road and usually helps you avoid congested aircraft terminals.

Obviously, private aircraft charter is considerably more expensive than commercial flight.  However, the time saved by avoiding the commercial terminals as well as using point to point travel very often makes up for this additional cost.

Time is money.  This is an often used phrase, but seldom understoon until your time becomes worth a great deal of money.  As a business owner or high level executive, you have a lot on your plate and ever minute of time you spend standing in a secruity check or ticketing line is a minute spent away from the stuff you're paid to do and do well.

Most airports require you to arrive at least 1 hour before your flight departs.  Then factor in delays in boarding and possible delays due to aircraft traffic congestion at busy commercial airports.  Spend an extra 2 hours on a taxiway and that could easily cost a high level executive thousands of dollars in wasted time.

Once you arrive at your destination, you'll waiting for the person in front of you to get their overhead bags, then it's off to the luggage area where you'll most likely be waiting about 30 minutes for your bags to come out.  As we all know, too often, commerical airlines lose baggage.  If you've got important business documents in that luggage, this could cost you a vital sale.

If you're used to flying first class and enjoy the conveniences of early boarding and room enough to get some work done, you're not far from the world of private aircraft charter. In fact, with some of the new shared private aircraft services, the cost difference isn't that great.

A great deal of executive business travel happens fast.  A last minute snag in a contract and the need to visit the client means you're booking your commerical flights hours and not weeks in advance.  This adds to your costs as you know.

Factor the gross cost difference between a first class, last minute flight from your local major airport to the cost of taking a private aircraft charter from the much closer regional airport.  Now look at the time difference between the two modes of transportation.  You may find it's going to have a net COST to fly commercial.  You could be saving your company money by flying in a private charter.

Fractional Ownership

In the aircraft world, fractional ownership is typically managed by a private company such as NetJets. Rather than your company gathing together other businesses interested in shared ownership, these private companies take care of all of the details. You simply buy into the private fractional aircraft ownership. This is a great option if you've got a good number of people needing aircraft transportation on a frequent bases. This is the last step before heading up to privately owned corporate aircraft.

Pre Paid Jet Cards

With the jet cards, your corporation would pre-pay for X number of flight hours. When you need to fly, you simply use the balance left on the cards. This is a great way to go if you don't need private charter services all the time but want it ready and available when the time arises. Make sure you check the details as many of these jet card services have a specific time in which you need to use your hours.

Local Private Charter or Air Taxi Services

A fixed base operator or even one of your local flight schools at your local regional airport will often provide you with private charter services as you need them. Most of these businesses aren't going to provide jet services, but rather smaller turbo prop aircraft for short hops within your region. This is a great option for a small business owner who needs these services rarely. It's often used for private individuals looking to create a very special vacation for themselves.

Private Air Cargo Services

When you have a part that needs to get there within minutes, you don't have time to wait for even the fastest air cargo services who promise next day delivery. If you have an important piece of equipment down you need the parts now, not tomorrow by 10am. This is also used frequently for emergency medical needs such as donated organs and patients needing emergency transportation to a different facility.
