How about to credit these miles to Finnair, as with Finnair I will credit the most miles.
Yes to AA/BA/IB ffp. And you could credit to the AY ffp
With Oneworld the marketing carrier (flight number), if eligbale, determines the earning.
The booking fare class is important. Some fare class can earn a small % or nil, depending on the ffp.
FF miles/points/avois are not equal to earn or burn. Frequent miles in a ff program that you can use are worth more than ff miles in an orphan ffp you will never use, even in the earning rate is
better.
