Best guess 330 TP total, I'm not even going to attempt the Avios! (90+40+35 each direction)

That's based on Premium Econ YVR-LHR on BA metal, then economy on AY metal LHR-HEL-SIN.

Just a note that very few people here have memorised all the BA flight numbers, I suspect even fewer have done so for the AY ones For TP queries, cities are more helpful than flight numbers.
