I have asked this before with zero response from those spruiking the benefits if this "cadetship".
In order to be employed by Jetstar as anything other than a junior FO and therefore eligible to earn these $100k+ salaries, the pilot must hold an ATPL. The pilot must hold a minimum of 250 hours PIC or 500 ICUS, therefore, the cadet must be provided at least 500 hours ICUS in order to gain an ATPL. Is Jetstar doing this?
