I can’t speak with much authority on this subject because we don’t usually buy much in the line of alcohol but when we do, I always pick it up at the airport duty free shop for convenience in carrying it. Years ago we saw someone’s suitcase on the baggage carousel at JFK and it was leaking something all over the conveyor belt. That was enough to convince me I’d rather carry it on than pack it in my luggage, jic. With my luck……🙂🙂
