Yes, you can smoke at Keflavík International Airport (KEF) at the six smoking and e-cigarette points Isavia marks on its airport map: four on Level 1, three around the Main Terminal and one at the South Terminal, and two on Level 2, one in each terminal. The map gives no gate numbers and no side of security, so ask staff for the nearest point; in March 2026 travellers described one across the hall and up the stairs from passport control, one in the non-Schengen area and one across from the toilets near the front of the terminal.
Main Terminal
Isavia marks three smoking and e-cigarette points on Level 1 around the Main Terminal, outside the building, and one on Level 2, with no gate numbers, no side of security and no opening hours. Icelandic law bans smoking in the indoor service spaces of a building open to the public (Tobacco Control Act, Article 9), so the points sit outside those spaces; ask staff for the nearest one. In March 2026 travellers described three smoking areas without naming a terminal or level: one across the hall and up the stairs from passport control, one in the non-Schengen area and one across from the toilets near the front of the terminal. Isavia publishes no change to its smoking points; it is expanding and renovating the main shopping area, so ask staff if a marked point is not where the map shows it. The Icelandair Saga Lounge publishes no smoking rule, so ask the lounge staff.
South Terminal
Isavia marks one point on Level 1 and one on Level 2 of the South Terminal, with no gate numbers, no side of security and no opening hours. Ask staff for the nearest one.
Vaping
Isavia’s map covers smoking and e-cigarette areas together, so vape at the same marked points; the airport publishes no other vaping rule for the terminal, so ask staff. Electronic cigarettes travel in hand baggage only.
