SQ Fare Basis WPPX - Fare Classes for VFF SC Earn

[Pleb Status]

I am currently looking at booking a SQ Y/PE combo fare ex PER. The flights PER-SIN v.v. will be in Y and the others will be in PE. I will be crediting to VFF.

The SQ fare type is Premium Economy Standard, the fare basis is WPPX and KF earn is supposed to be 100%.

It is unclear what fare class/es this fare will book into for VFF SC earn. If booked separately, the Y sectors would be fare class W and the PE sectors would be fare class P.

So, this fare could credit in one of three ways -

1. Y sectors into W and PE sectors into P (as if separate bookings and the most likely answer).
2. Both Y and PE sectors into W (as the fare basis starts with a W and this is normally the fare class).
3. Both Y and PE sectors into P (as the entire fare is a PE Standard fare with some sectors in Y).

Has anyone tried this type of fare previously and what was the result?

Edit: Amex travel appears to indicate it will be option 1 but I cannot see the same fare basis...
