Is there a programme in oneworld which allow me to retroactively claim up to three months before joining? Finnair itself does not allow and BA only allows on their own flights but not on partners.
R & Z are both low earning miles. Without status on AA, you'll hardly earn anything... so just take it as a lesson, and experience that you won't be able to claim any miles for these flights.
What routing were you on anyway?
