I know the first comment to this question will be “you should have booked earlier” but ..

I suddenly have the coming weekend free (Oct 24-27 incl) and would like to use it to earn 160 or even 200 QPs as that would clinch SEN for me.

However a one stop LON-Poland return is coming out at ~€800-900 (in J and therefore ignoring LO fares). Plan B will be to do an early Dec trip to a Christmas market so it’s not the end of the world if I can’t find something at perhaps sub €500 … so are there any good intra Europe city pairs I could investigate?

Edit: found LHR MUC via VIE for £570 so heading towards being a sensible price

(I’m UK based so would have to factor in positioning but it’s just me and my backpack and with reasonable time).
