Last 32 days (from theqantassource.com route tracker)
- 3 non-refurb 330-200s
- 16 non-refurb 330-300s
- 13 refurb 330-300s

So probably a lower hit rate than most routes with 6 of 9 active 330-300s refurbed (there are 10 -300s but QPF is presently under maintenance)
However by mid-Feb we are likely to be at 8 of 9 (possibly 9 of 9 depending on the order they are completed - QPH/QPJ shouldn't need C8 checks so will be quicker) so the chances will be higher, but still not guaranteed.

(And Congrats on your First Post on Flyertalk, hopefully it won't be another 6 years until your next one!)
