I think (happy to stand corrected) you have also expressed the opinion that many ex TN AIPA members would prefer to return to AFAP?
As of today there are probably fewer than 10% (maybe less than 5%) of the original TN pilots within the mainline body of Qantas pilots - fewer still if you include the regionals and other Qlink entities.
Going through the process of enabling AFAP to represent those pilots, and the others who may wish to join them, would be inefficient and probably counter-productive when compared to those pilots lobbying their closest* AIPA CoM member to negotiate for the same outcome.
* By closest, I mean any of those of the same rank, on the same fleet, same seniority, same background, same base preference, same age and family demographic…….
Without wishing to sound disparaging, most Pilot association CoM members, AFAP or AIPA, are usually there for somewhat selfish reasons - looked at the right way, that's a good thing. Some are more selfish than others!! The point is though, that
these days, you can nearly always find a CoM member to represent your interests as it will often serve their's too.
