Its not about retirement at 55 or 65 instead, its about not retiring at all, as numerous court cases with Air NZ and some of its flight crew have shown. Will be interesting to see what happens when NZ based CX pilots reach 65 and opt to continue flying even with nowhere for them to fly to (apart from domestically in NZ, as Air NZ crew have done, or working in the sim).
Pyrrhic victory if the company closes the NZ base as a result.
