Yes, you can smoke at Danish airports: after security at Copenhagen Airport (CPH), on the outdoor terrace at the A and B gates (the airport’s pages name finger B and Gates A for it, so ask staff which way) and the terrace at gate E135, in the two smoking cabins at the start of the C finger after passport control, and in the Aspire Lounge’s closed smoking room; before security, at the yellow smoking zones between the entrances to Terminals 2 and 3. Billund has an indoor smoking cabin after security and Aalborg an outdoor area outside the terminal. Danish law bans smoking inside buildings open to the public except in a smoking room or smoking cabin (Act on Smoke-free Environments).
Denmark Airports Compared: Before and After Security
Before security, you can always smoke outside: at a designated smoking area where there is one, or outside the airport property, beyond the terminal kerb and car parks. After security, Yes means there is a smoking area past security and a dash means none is listed. Each airport’s page has the details.
| Airport | Before security | After security |
|---|---|---|
| Aalborg (AAL) | Yes | – |
| Billund (BLL) | Yes | Yes |
| Copenhagen (CPH) | Yes | Yes |
For international travel through Denmark, Copenhagen (CPH) at Kastrup is the airport that matters; the smaller airports at Billund and Aalborg handle regional and leisure traffic.
How Danish Airport Smoking Works
The Act on Smoke-free Environments (consolidated Act No. 1632 of 2021) bans smoking indoors in workplaces and in indoor places open to the public, airport terminals included, and allows the owner to set up a smoking room (a separate, ventilated room that is not a passage and has no other function) or a smoking cabin (a free-standing unit with its own ventilation); the Act sets no general outdoor ban, so an airport’s open-air areas follow the airport’s own rules. Since 1 April 2025 (Act No. 1669 of 2024) heated tobacco and electronic cigarettes, with or without nicotine, follow the same indoor rules and the same room and cabin exceptions. The Act fines the employer or operator who allows smoking against its rules and sets no fixed amount for a passenger (Article 26). In practice at Copenhagen:
- Outdoor terrace after security at the A and B gates — the airport’s pages name finger B and Gates A for it, so ask staff which way
- Two smoking cabins at the start of the C finger, just above the 7-Eleven, after passport control
- Outdoor terrace at gate E135, after the security check
- Closed smoking room in the Aspire Lounge, after security near Gates A on the first floor, DKK 339 entry at the door
- Yellow smoking zones between the entrances to Terminals 2 and 3, the only places to smoke before security
- Electronic cigarettes follow the cigarette rules in the airport’s own areas; lounges and other partners set their own rule, so ask the lounge staff
- The airport publishes no opening hours for its smoking areas, so ask staff if one is closed
The Airports
Copenhagen Airport (CPH). Denmark’s main international gateway, at Kastrup just south-east of the city. After security the airport lists an outdoor terrace at the A and B gates (its pages name finger B and Gates A for it, so ask staff which way), two smoking cabins at the start of the C finger above the 7-Eleven, after passport control, and an outdoor terrace at gate E135, with no opening hours published for any of them. The Aspire Lounge, after security near Gates A on the first floor, has a closed smoking room; any passenger can buy entry at the door for DKK 339. The SAS Lounge and the Carlsberg Aviator Lounge offer no smoking facilities and send their guests to the airport’s smoking areas. Before security, the only places to smoke are the yellow smoking zones between the entrances to Terminals 2 and 3.
Billund Airport (BLL). Denmark’s second-largest airport and the gateway to LEGOLAND. It keeps an indoor smoking cabin airside, connected to the departure hall in the waiting area behind the WHSmith shop on the way down to the gates — a genuine after-security option. Landside, smoking is outdoors before check-in, and arriving passengers wait until they’ve collected their luggage and stepped outside the terminal.
Aalborg Airport (AAL). Northern Denmark’s main airport. There’s no indoor smoking room here — smoke outside the terminal, where ashtrays are provided; the same rule applies to e-cigarettes.
Tips for Smokers at Danish Airports
- At Copenhagen, the terraces at the A and B gates and at gate E135, the two C-finger cabins and the Aspire Lounge room are all after security, so a transit smoke needs no exit; ask staff if one is closed, as no hours are published
- Billund is the other airside option — its smoking cabin sits past security, behind WHSmith on the way to the gates
- Aalborg has no indoor room — smoke outdoors, before security, where ashtrays are provided
- The two cabins at Copenhagen are at the beginning of Gates C, just above the 7-Eleven, after passport control
- E-cigarettes follow the same rule as cigarettes in Copenhagen Airport’s own areas; lounges set their own rule, so ask the lounge staff; at Billund, e-cigarettes may not be used indoors at all, not even in the smoking cabin, so vape outdoors only
- Before security at Copenhagen, smoke only at the yellow smoking zones between the entrances to Terminals 2 and 3
