One of the major differences is that Private jet can fly into smaller regional airports that Commercial scheduled airline services cannot operate, this means that you may be able to get nearer to your destination and fly to remote destinations. For eg: if you plan to visit a remote island, commercial airlines may not offer a direct route, but with a private jet charter this is possible.
Further to this, private charter allows you the convenience to choose exactly when you want to fly and you are not bounded by fixed schedule. Also private charter offers relaxation and comfort during duration of your flight, be it working or sleeping, without being disturbed by other passengers, you can control the air-conditioning, select your preferred in-flight dining menu and tailor the flight to suit your exact needs, extra leg room padded reclining chairs and sometimes even full-size beds for complete relaxation.
