The Y fare buckets are identical ex AKL and ex SYD on the random day I chose. That suggests there is no difference in the number of Y seats being reserved.
It's also the same with W.

And you know we can see your previous posts, right?
You didn't speculate that the same seats are reserved ex AKL & ex SYD.
You speculated that not 'many seats will be reserved ex AKL'.
There are, in fact,
heaps of in J, W & Y seats for sale ex AKL.
Also, their margin can't be that great ex SYD. They're having to price their Y fares the same as their American, Indian, South American, etc competitors and cheaper than their Asian competitors. Edit: They're getting a bit of a premium in J on some days.
