I agree with Karfa on the other points although you mind find it a much harder case to argue given it was booked with AA (rather than BA) prior to April 28th.
I knew SH had had the '25%' point decrease - I didn't realise that had happened to LH too ... seeing 20 points in deep discount economy makes that a long road to even bronze!
I had a similar period with a WTP booking, with the return leg on AA, which does not have Premium Economy, but which has Main Cabin Extra, which I find to be perfectly ok. I only received 20 TP's for the return flight
