Every major Thai airport keeps designated open-air smoking areas at the terminal kerbsides, forecourts and car parks, and two of them reach past security: Bangkok Suvarnabhumi’s paid Miracle Lounge terrace near Gate D5, and Koh Samui’s open-air gate gardens. The policy dates from February 2019, when indoor smoking rooms at every major Thai airport were closed — a shift that brought Thailand into line with Singapore and Malaysia, and left it more restrictive than its eastern neighbours: Indonesia, Vietnam and the Philippines all maintain indoor airport smoking rooms.
Today’s reality: Bangkok Suvarnabhumi (BKK) and Don Mueang (DMK), Phuket (HKT), Chiang Mai (CNX), Krabi (KBV), Koh Samui (USM), Hat Yai (HDY), Chiang Rai (CEI), and U-Tapao (UTP) all rely on outdoor areas; none of them have post-security indoor smoking. Airside concessions are rare: BKK’s paid Miracle Lounge near Gate D5 has an outdoor smoking terrace (1,500 baht) that covers layovers, and Koh Samui’s open-air gate pavilions keep marked garden smoking spots airside; otherwise a smoking layover at most other Thai airports requires exiting customs and security, which is impractical for connections under three hours.
How Thai Airport Smoking Works
The 2019 indoor ban prohibits smoking in enclosed public spaces at all civil aviation airports, implemented under the Tobacco Products Control Act B.E. 2560 (2017) alongside a Ministry of Public Health announcement (B.E. 2561/2018) that designates public places and state enterprises as smoke-free zones or as carrying their own designated smoking areas. When Airports of Thailand closed the indoor rooms at its six airports on 3 February 2019, its own announcement set out AOT’s policy of designating outdoor points as smoking areas “in suitable locations” at each one, rather than publishing a fixed list of gates or floors. The outdoor areas are:
- Curbside near terminal entrances at most airports
- Sometimes in car park areas (Don Mueang especially)
- Marked with English/Thai signage
- Free to use
- Subject to tropical weather — heat and humidity in summer, occasional torrential monsoons
There are no indoor smoking rooms anywhere, even in airline lounges. Airside options are outdoors: the paid Miracle Lounge at BKK (near Gate D5) keeps an open-air smoking terrace after security, and Koh Samui’s open-air gate pavilions have marked garden smoking spots airside.
The Major Hubs
Bangkok Suvarnabhumi (BKK)
Thailand’s primary international gateway. Outdoor smoking areas landside — near the Airport Police Station, Magic Food Court at Gate 10, and Parking Zones 2-3. Airside, the paid Miracle Lounge near Gate D5 keeps an outdoor smoking terrace (1,500 baht); otherwise transit passengers must clear immigration/security to smoke.
Bangkok Don Mueang (DMK)
One of the world’s largest low-cost-carrier hubs. Ground-level outdoor areas outside both terminals — the main one at the far end of Terminal 2 near the car park, and another between Terminal 1 and its parking structure — accessible only by exiting security.
Phuket (HKT)
Outdoor only. Three terminals — T2 (international, opened 2016), T3 (domestic, reopened June 2018), and Terminal X (charter, 2014). Ground-level outdoor areas on each terminal’s forecourt; the old Smokers’ Pub on T2’s Floor 2 closed under the 2019 ban.
Chiang Mai (CNX)
Distinctive setup with a standalone outdoor smoking building accessible via Exit 9 from the main terminal. The structure is essentially a covered open-air pavilion. Burning-season air quality (February-April) makes outdoor smoking less pleasant than at coastal airports.
Krabi (KBV)
Outdoor only. Gateway to the Phi Phi Islands and Ao Nang. Terminal 3, the new domestic building, opened in stages through October 2025 and now links the older Terminals 1 and 2; the main smoking area is at ground level outside the domestic check-in hall, with more marked points outside the other entrances.
Koh Samui (USM)
Uniquely Thai — owned and operated by Bangkok Airways, built in open-air thatched-roof tropical style. The whole airport is essentially semi-outdoor, making smoking accommodation natural. Seven boarding gates, all relaxed, with marked garden smoking spots airside behind the VAT-refund kiosk near Gate 7 and behind Gate 2.
Hat Yai (HDY)
The main airport for Thailand’s five southernmost provinces and the gateway to the Malaysian border. AOT closed HDY’s indoor smoking rooms on 3 February 2019, one of six AOT airports affected that day, and stated its policy of designating outdoor points as smoking areas at suitable locations outside the terminal instead of publishing an exact gate or floor.
Chiang Rai / Mae Fah Luang (CEI)
The air gateway to Thailand’s northernmost province and the Golden Triangle. Also one of the six AOT airports that closed its indoor smoking rooms on 3 February 2019, under the same policy of designating an outdoor point outside the terminal rather than a specific gate or floor. In April 2024, CEI’s own director publicly addressed a single dated case of a passenger who vaped aboard a departing flight.
U-Tapao (UTP)
The Rayong-Pattaya region’s airport on the eastern seaboard, a joint civil-military field run by the Royal Thai Navy with commercial service handled separately. UTP is not one of AOT’s six airports; it is bound instead by the same nationwide Tobacco Products Control Act B.E. 2560 (2017), so its terminal interior is smoke-free and smoking is outdoors only, outside the terminal.
The Vape Warning
This needs to be flagged prominently: vapes and e-cigarettes are illegal in Thailand. Importation has been banned since the 2014 Ministry of Commerce notification, sale is banned under the consumer-protection decree that replaced the 2015 order in 2024, and devices brought in are treated as prohibited goods under customs law — carriage can bring confiscation, fines, and in serious cases imprisonment. Enforcement varies — sometimes officers wave through obvious tourist personal vapes, sometimes they don’t. Do not bring vapes to Thailand under any circumstances. Cigarettes themselves are legal and freely available.
Tips for Smokers at Thai Airports
- All Thai airports are outdoor-only since 2019 — no indoor exceptions
- At BKK the paid Miracle Lounge terrace near Gate D5 is the airside option; otherwise BKK and DMK require exiting security to smoke — plan 60-90 minute round trips
- Chiang Mai’s standalone smoking pavilion is the most distinctive setup
- Vapes and e-cigarettes are ILLEGAL — do not bring them
- Cigarettes are inexpensive (~80-120 THB / ~$2-3/pack)
- Tropical weather: cover is available at most outdoor areas; bring a hat for the heat
- For long Asia-Europe transit, consider routing via Singapore (outdoor gardens) or Doha (post-security indoor) instead
