Porto Airport (OPO) allows smoking only in its designated areas and publishes no list of where they are, inside or outside the terminal. Travellers described no smoking room at the airport in April 2025 and no smoking area after security in August 2026, and a reader asked the airport on 17 October 2026 for a smoking area for long waits. Before security, ask staff for the nearest designated area; if there is none outside the terminal, smoke outside the airport property, beyond the terminal kerb and car parks. Portuguese law names airports among its no-smoking places and lets them set outdoor smoking areas and reserved indoor rooms (Lei n.º 37/2007, articles 4 and 5).
Elsewhere in Portugal, Lisbon Airport keeps smoking rooms after security in Terminal 1, and at Faro Airport travellers described a smoking room in the Gates B zone in August 2025.
Before security
The airport publishes no location for its designated smoking areas and marks none on its pages. Ask staff for the nearest designated area; if there is none outside the terminal, smoke outside the airport property, beyond the terminal kerb and car parks.
After security
The airport lists no smoking area after security. In August 2026 travellers described none after the security checkpoint, and in April 2025 no smoking room at the airport, one adding that it used to have one; a reader asked the airport on 17 October 2026 for a smoking area for the hours of waiting. The ANA Lounge, after security on Floor 3 and open 04:00 to 21:00, lists no smoking facility and is under improvement works. Ask staff; if they send you outside the terminal, you leave the secure area and clear security again afterwards, and the airport publishes no transfer procedure for this.
Vaping
The airport publishes no vaping rule for the terminal, so ask staff before you vape; it asks that electronic cigarettes and lighters travel in hand baggage and bans electronic-cigarette use on board. The Portuguese rule on e-cigarettes is on our Portugal guide below.
