Initial web enquiry followed by emails to Customer Service. Given form to fill out and sent proof of existing Velocity Platinum status and flight records. Also told them how intended to take at least 12 long haul business or first class flights each year with Singapore Airlines. No status match or further correspondence provided. Since found out I am assured Qatar Privelege Club Platinum status match with my Accor All Diamond status if I take just one Qatar flight, so I will probably use Qatar instead for my future long haul flights to Europe.
