I don't have any plans to swamp the UK with contraband fags - it's cheaper to buy them duty paid in the Far East, let alone duty-free - but I'm very intrigued by this thread. One of many reasons I fly QR whenever I can is because they fly out of T4 which as has been noted in other threads, actually has an airside smoking area. But on my next HKG trip somehow, for the first time in yonks, BA came up in policy and since I'm good for TP for the remainder of the year and I want to use my shiny new CCR card, I thought bugger it, I'll go BA and pocket the bonus Avios.

But I'm *not* looking forward to maybe three hours airside at T5 without a smoke. Especially after what will doubtless be a feast of epic proportions in the CCR. Is this TTL>5C dodge legit? I can just leave my stuff in the lounge, hop on the transit with passport and BP, walk out through immigration and then walk in again through Security? Klaxons will not sound?

For the avoidance of doubt, I can live with "frowned upon" if that's as bad as it gets.
