Kirrungi - There are no BA staff at the boarding gate in Nairobi, only Swissport. The Duty Free shop is remote from the BA gate and is not controlled by BA. I would suggest its the personal responsibility of the traveller to understand the restrictions on carrying liquids, particularly if transferring through any UK airport. Unless the gin was bought on board the BA aircraft there's nothing the cabin crew can do to assist, it won't be permitted through a UK airport security channel. Whilst Mr Mac has some valid points, some of the complaints are simply the reality of modern air travel with any carrier and are certainly not unique to BA. I recently chatted at length with a former Emirates steward who now worked for BA. He found it ironic that BA passengers often complained that things were better on EK as when he'd crewed the Emirates UK routes he often encountered passengers complaining that things were better on BA!
