I sent my FInnair Gold card, and got such an answer: which is confusing, as it explicitly says that they match Finnair Gold!!! I get it that it is not not Oneworld Emerald, but they specifically say they match Finnair GOLD???
"Miles&Smiles members who also have membership with the Skyteam (Elite Plus), One World (Emerald), Emirates (Gold - Platinum), Etihad (Gold - Platinum), El Al Israil Airlines (Platinum - Top Platinum), Finnair (Plus Gold), Oman Air (Sinbad Gold) are eligible to status match for Elite membership.
Therefore, since your membership status is Gold, we unfortunately cannot satisfy your demand under the Miles&Smiles program rules."
