Thank you TBS. I recognise you from the BA forum, where I'm more usually found lurking
Alas, I'm a lowly bronze so I'll be only able to use the business lounges (or the combined ones).
Admittedly, my holiday won't be ruined if I don't get to lounge hop, and so long as I get a decent coffee, a shower and a glass of champagne (or G&T) as a minimum I'll be happy. I suppose my only concern with 256 would be a heavy delay out of LHR (possible in January) and I find myself being rushed from gate to gate in HKIG.
Related to my point above, I'd love to know the best CX HK lounges for coffee, or the one with the nicest showers (or the shortest queues).
