Since this has morphed into a discussion about a potential RIN, I would urge 747 pilots, particularly FOs and SOs whose plan for any future RIN is to displace more junior pilots on more senior types, to read Clause 18.1.2 (e)(iii) VERY carefully. Think about what "higher status" positions the company may "offer" to avoid you being demoted to a "lower status", thereby removing your right to displace. The company could even argue that types not included in the LH EA, that include a promotion, would not be "lower status".
Interpretations of this clause could vary wildly. The company will take a certain view that could save them millions in retraining costs and, because of that, will probably be willing to die in a ditch, up to and including FWC and the Federal Court to defend it. I don't think AIPA would have the stomach for a fight on this issue so it would be unlikely to get that far.
