Private discussions with teammates or clients onboard airlines is impossible. Having your important or sensitive discussions overheard by others in the aircraft is too high a risk to take. A private jet offers you complete privacy and a quiet and comfortable environment to work in.
You fly where you want, when you want, in the charter aircraft you want, with complete privacy and the advantage of no waiting around in airline terminals. Time is money and every wasted hour is a lost opportunity. Private aircraft charter puts you in control of your schedule and stops the need to work to airline timetables and delays.
