I’m happy Champagne is still available on LX, although I miss the service when you got a pre departure champagne or orange juice served after boarding... Must have been years since I last had that. I’m not sure if Edelweiss maybe still do it.
In conclusion it’s still better than the pathetic Sekt they serve on LH...

As for OP: I will fly from ZRH on 18th Apr. and could guest you to the Sen lounge in the morning if you are around then.
