Yeah clear as mud for me to. Best thing would be to ask AFAP or VIPA.
I think you get a GDOJ but if you get the ATR you are subject to the 10% limit so I guess it comes down to how many ATR pilots there are to work out how long. I guess once the 10% limit is reached then a junior SO could trump you. Thats my understanding only.
Qlink another option, QF lounge access, business class duty, good meals, good hotels and very good staff travel. I'm not sure what their progression is into mainline or Jetstar but the head honcho did send out an email regarding progression within the company so its come a long way from 10 years ago.
