Submitted a request via the Feedback section of the Miles & Smiles account page and including a screenshot of my BA membership card, flight activity and passport page. Received a response within 12 hours stating: "Thank you for your interest in Miles&Smiles, the frequent flyer program which offers a whole world of benefits. However, the level of your frequent flyer program membership is not equivalent to Star Alliance Gold. As such, we’re unable to fulfill your request to match your membership status to Elite. Your membership status in another frequent flyer program must be equivalent to at least Miles&Smiles Elite status to be matched."
