Thanks everyone for your responses.
When I started this topic I also emailed Virgin but did not expect to get a response before I leave in two days time. Well, I was surprised to get an email this morning stating in part:
'If you want to BYO wine to enjoy on board, we allow two (2) 750ml bottles per cabin in carry-on luggage.'
So I will bring two bottles of wine in my carry-on and see how things work out.
Thanks again.
