Not really a UK question, but hope someone can help. A friend will be travelling on BA from Johannesburg via Heathrow to Poland soon. If she buys bottles of booze in duty free on departure, will she be able to take this through Heathrow? I heard stories of them confiscating stuff even though it was wrapped in those special plastic bags.
I answered this time, but my answer has been mysteriously erased. I am of the opinion that if you stay on the track side and not have to leave the Immigration contact your next flight, there should be no problem as duty-free bottles remain sealed.
