Yeah, CX married segments are a major pain, especially to OZ and NZ from Japan. It is unfortunately though something we have to deal with on these tickets. But for what it's worth, QF is absolutely no better on married segment itineraries. CX and QF both love to have C9 D0 on those.

When is your current CTS-xHKG-PER? If it's not near any Japanese or Western holidays then you might be ok, but if anywhere near Christmas, New Year, Easter, Golden Week, Obon, etc. then it'll be a lot tighter on availability. The entirety of Ski season from CTS can also be problematic, lots of Aussies come up for that, and a fair bit from HKG itself these days.
Can the married segments be "broken" by using the codeshares of AY/QF/JL?
