I have never had Finnair fail to recognise a BA PNR whether it was Avios or cash.
Yes same with me, Finnair.com has always found any Amadeus booking I have on oneworld. Even something like a booking on EK made through QF has come up fine there. RJ is also on Amadeus so it should at least be visible.
