We were in 6028 for the Transatlantic and smelled cigarette smoke in the hallway everyday. We just figured someone was smoking in one of the two particular cabins that it "seemed" to be coming from. We never thought it would be from an outdoor smoking area! Actually, reported it once (for safety) to our cabin steward who seemed surprised by our complaint. Once inside the cabin, and even on our balcony, we could not detect the smell.
