Very nice too, impressive that's for sure. I do have a small collection of Yquem at home running back to 1976 looking for an exceptionally rainy day. To have that on a plane wine list is truly exceptional, I hope there were some desserts to go with it, although to be honest I'd be happy slurping it all on its own.
Some far Eastern carriers like SQ and CX don't carry any dessert wine in F. On SQ they'll serve you your own if you bring one on board from duty free, but not CX.
