The champagne on other routes at the moment seem to be Bollinger La Grande Annee 2015, which is very nice although I generally don't have much more than a glass (if even that) but I had quite an amusing time coming back from DXB last week where we were at the gate for about 2 hours whilst they sorted out someone being offloaded as they were unwell and then getting their bags etc. and the lady across the aisle from me proceeded to get absolutely hammered with frequent top-ups. She then snored soundly all the way home.

That's the way to do it!
