The whole airline industry seems to cut down on champagne. Even SQ! No more Piper Heidsieck Rare in their FCL (TPR has Taittinger comptes de champagne) and on board only a single bottle of Krug. Dom is gone for a while already.
I always enjoyed the Rare before flying back to Europe on LH/LX.
I still remember when SQ served Dom in their lounge. Until end of Aug 2007.
