Yes, you can smoke at Shannon Airport (SNN) after security, at the smoking area next to the airport’s transit lounge: Brendan M, a reader, described it on 4 September 2026 as an outdoor area up two flights of stairs from the main bar and duty-free area. Before security, smoke at the designated area outside the front of the terminal building. Smoking is allowed only at these two areas, and the airport’s own statements on vaping contradict each other, so ask staff before vaping; Irish law allows no smoking room inside an airport terminal (Public Health (Tobacco) Act 2002, Section 47).
After security: the area next to the transit lounge
The airport’s smoking area after security is next to its transit lounge. Brendan M, a reader, described it on 4 September 2026 as an outdoor area reached by two flights of stairs from the main bar and duty-free area in the departures lounge. The airport publishes no hours for it and marks it on neither of its terminal maps, so ask staff for the way and whether it is open.
US Preclearance
The airport lists no smoking area after US Preclearance, and its Ború Lounge (open to all passengers 06:00 to 19:00, €50 a person for up to three hours, no smoking room listed) cannot be entered after Preclearance either. Smoke at the outdoor area next to the transit lounge before you go through, allowing the 60 minutes the airport asks for Preclearance, and ask staff if you are unsure of the way.
Before security: outside the terminal front
The designated area is outside the front of the terminal building. The airport publishes no hours for it; ask staff for the nearest way out to it from arrivals.
Vaping
The airport allows vaping only at the same two designated areas as smoking, outside the terminal front and next to the transit lounge. It also says e-cigarettes and vaporisers cannot be used within the airport premises or during the wait to board, so ask staff before vaping at either area. It publishes no rule for heated tobacco.
