They served P2 to me on the ground in DXB on the way to IAD. They didn't run out, despite a pretty full cabin. I think I probably had ~4 glasses and my wife ~2 - so that's one bottle done. I saw another passenger take at least a couple of glasses, so my best guess is 2-3 bottles are loaded. FWIW I didn't love the '04 P2 and was perfectly happy with the regular '15, though of course '08 or '12 would have been preferred...

JFK is showing '03 Mouton and Sassicaia '14 in February. I have found Sassicaia in the lounge, I have not found Mouton - but I have heard of people that have.
