'Finnair flights' sounds like AY coded and 'flown on Finnair' sounds like AY operated. 'Credited to Finnair ... at 250% of miles flown'. It looks like the key is 'bought through a different airline', such as a OW RTW!
Or can Matt be proved wrong?
Data point from my recently finished DONE3, ticketed by AA.
I had 2 AY flights in it (AGP-HEL-OSL on "real" AY flight numbers, no codeshare) and first some totally random Avios posted.
I reached out to customer service (as some other flights required fixing) and asked about how those 2 flights were calculated. They then adjusted the Avios for both flights to a much lower amount without a real comment and only after another follow up they confirmed both legs were posted as spend based (portion of the leg / ticket) x AY+ status bonus.
So it seems for RTW tickets crediting to AY+ one should avoid AY flight numbers completely and only relay on codeshares if on AY metal.
I am currently trying to prepare a small thread about my overall experience BA(E)C -> AY+ but takes time (I am a lazy writer

).
