Received my invite the other day, I've had a Plat card since it came out in Norway some years ago — did a global card transfer to Spain 2 years ago. I've since then put approx. €150-200K on the Plat card annually, from premium travel and high-end shopping to daily groceries. Initiation fee is €3000 and the annual fee is €2000, while MR earning is 1.5 per €1 instead of the normal 1:1.
Will report back on the benefits once I get the card.
