Affiniture Cards Limited have made a strategic decision to withdraw the Miles & More Cards from the market. We are sad to see Affiniture Cards Ltd. leave this market, but as our Miles & More members on the British market are very important to us, we are still evaluating options for successor products. As its not possible to find a new partner overnight, Miles & More decided to extend the validity of earned award miles until 31st of December 2021.
