Travelling by private jet means that you can be pre cleared through customs and just pass through the VIP private charter terminal to access or leave your private jet. This eliminates the worries linked with commercial flights, and in addition you don’t have to depart when the airline tells you to, simply arriving and leaving at a time which works for you. If you are late, the captain will wait. Alternatively if you live near a smaller airport, you can depart from there avoiding large commercial airport traffic.
