Arrive in the lounge, find the Champagne and have a glass. Maybe a second. Board, and for Club Europe wait. More Champagne. Basically every flight review I ever write is, "Here's Trent drinking more Champagne and here's a picture of each one". I love it! Not because of any thinking around it, it is just nice. I'd choose cocktails if I could but it's the next best thing.
I have some really lush like records that I will not mention with my imbibing on a 1 hour flight that we shouldn't mention here
... But yes, I love it.
