It depends a little too on whether there is more than one RIN. If there is only one RIN then the most senior 744 pilot named displaces the most junior A380 Captain. Then the next most senior displaces the next most junior. There comes a ‘cut over’ point at which the 744 Captain will still have Pilots junior to them on the A380 but those A380 pilots have already been displaced. Therefore the 744 pilot can’t displace to the A380.
I agree with Tankengine. There is a cutover point also on the return of service from the 744 driver displacing. If Qantas only gets 12-18 months out of them before having to re-train for their position once they retire they may decide to throw a couple of hundred K at them to get them to go. Certainly a few of 744 Captains I’ve spoken to reckon they don’t intend to stick around too long if they’re not offered cash to go. Essentially they’ll ‘earn’ what they should have received via VR and then go. Double training will occur anyway.
eg if the RIN were done today, no one on the 744 below about seniority 130 would get to the A380.
