I prefer dining at CX F lounge. Having BA Gold and flying Finnair (CX lounge is the preferred lounge for AY) I have never had a problem getting in. After dining I go to BA lounge for snacks (scones and finger sandwiches) and champagne. I have to say I liked the old furniture better givning more privacy. Now it is a much more open place.
I had a question earlier which no one has answered. I got a card with text British Airways First. Does anyone know why.
