Was looking at booking one of the PE fares in the BA sale and upgrading to CW using Avios (either via my IB or BA accounts).

Question is.. do you still earn elite points and Avios based on the original purchased ticket class?
I had heard on the BA forum these sometimes post as 0 tier points, and a lot of hassle is needed to get the points retro credited.

I need the elite points to retain Platino for next year, so wondering whether I just fly in PE or take the risk in upgrading the ticket..

Thanks in advance
