You are part of the Qantas group. Allan has a hard 3% line drawn in the sand, and he is not going to budge. Forget about it, it's not going to happen.
If Jetstar pilots get 10% or 5% or whatever, next Qantas pilots will be going for 10%, then Network will want 20%, then Qlink will want 12% to catch up blah blah blah. It's just not going to happen. Forget about it.
If you want pay parity with Qantas pilots, well sorry at some point you need to understand you applied, and work for a LCC. You can't have all the bells and whistles that mainline pilots get. Your passengers don't pay $10k for a business class ticket.
If you want more, then apply for mainline, or come over on the MOU. The latest internal rumour is that all future recruitment will be from within the Qantas group only. No externals.
And I wouldn't be giving up anything for Qantas club access. It's not worth it.
