Yup, I should but this was specifically interesting as the booking is Premium Economy (which is really nice for BA tier points, but don't know how they rack up for AY) on BA and shows Eco T on Finnair, and I Wasn't able to decipher the exact tier point amounts, hence askihn for advise

The reason behind the double OWS is a whole different thing, but suffice to say , OWE was not in the cards
