You are asking yourself the wrong question. If you want to base a move from regional to jets just on the rostering then your focus is too narrow. Ask yourself what you want to be doing in 10 years time then 20 years time. You just can't decide on a whim that you are going to move on to the next step as that next step may not be available. At Jetstar they have recruited pilots from Rex who were happy to stay there until management upended there lifestyles. A lot of these pilots had over 10 years service with Rex. Imagine if they had made the move to jets 10 years ago. If you want to fly jets then just apply and sort out basing and rostering issues later.
