Yes, you can smoke at Shannon Airport (SNN) — at a specially provided location adjacent to the airport’s transit lounge, airside, and at a designated area outside the front of the terminal building, landside.
Shannon serves the west of Ireland and includes a US Customs and Border Protection preclearance facility for outbound flights to the United States.
The airport’s own site states plainly that Shannon “is a smoke-free and vape-free airport environment in line with Public Health Legislation,” with smoking and vaping confined to two named spots.
Smoking Airside (Adjacent to the Transit Lounge)
Per the airport’s own description, one designated area is “a specially provided location adjacent to the airport transit lounge” — airside, for passengers who have cleared security. The airport’s site does not say what the area looks like; a reader report received in September 2026 fills that in: it is an outdoor smoking area, reached by climbing two flights of stairs from the main bar and duty-free area in the departures lounge. Allow a few minutes each way for the stairs if you are timing a cigarette against a boarding call.
Smoking Landside (Outside the Terminal Front)
The second designated area sits outside the front of the terminal building — the option for passengers before check-in or after collecting bags on arrival.
Vaping
Shannon’s official policy treats vaping the same as smoking: e-cigarettes and vaporisers are confined to the same two designated areas — outside the terminal front and adjacent to the transit lounge — and cannot be used elsewhere on the airport premises or while waiting to board.
