I would agree - you will definately not be pampered! But you will be MUCH more involved in the whole operation from catering through to flight planning at the last minute when the guys in the back change their mind on destination etc etc. Its a much more personal / customer focussed type of flying - when it all goes wrong there will be no locking yourself in the pointy end to let the cabin crew suffer! A number of guys try and get in at an FBO to get the experience required in dealing with biz jets, its a small world and who you know is very important when recommendations are needed.
