ANA Fare Codes

Is there any way I can look up the fare codes ANA use for their internal Premuim Class fares? Particlarly interested whether these get me 1 or 2TPs. Looking at the site it seems to be a business class equivalent, and at fares that are not much more on some routes than Y!

So far I've:

1) Asked VS customer care: who copied and pasted the information from their website and suggested I call them if I wanted more info. So I did, they repeated the information on thir websited - which only covers Y, J and F.
2) Called ANA in London and got the impression they didn't know what I'm talking about.
3) Made a booking on the ANA website and still no sign of fare classes.

Anybody have any other ideas?

Thanks

It's Y, so just the one TP per internal 'hop', not 2 [:(]
