14 Best Airports In Thailand (2026): Names, IATA Codes & Which To Fly Into

Suvarnabhumi is Bangkok’s main international gateway and the busiest airport in the country, handling around 60 million passengers a year. It runs 24 hours and sits about 30 km east of the centre. The name means Golden Land, after the late King Bhumibol. Most long-haul flights from Europe, the Middle East and India land here. The Airport Rail Link reaches the city in roughly 30 minutes; a metered taxi takes 40 to 60 depending on traffic. If you are connecting to a domestic flight, check whether it leaves from here or Don Mueang, because they are on opposite sides of Bangkok.

Don Mueang is Bangkok’s second airport and one of the oldest in Asia, in service since 1914. It closed when Suvarnabhumi opened in 2006, then reopened in 2007 to take the overflow, and is now among the world’s largest low-cost-carrier hubs. AirAsia, Nok Air and Thai Lion Air fly from here, so if your ticket is a budget hop to Chiang Mai or Phuket, it probably leaves from DMK. Allow at least three hours if you need to transfer between the two Bangkok airports; they are about 45 minutes apart in good traffic and much longer in bad.

Phuket is the busiest airport in the south and the third-busiest in Thailand, at roughly 14 million passengers a year. It sits at the northern tip of the island, about 32 km from Patong, so budget 45 minutes to an hour by taxi or airport bus to the main beaches. Direct international flights arrive from across Asia, Australia and the Middle East, which makes it the practical gateway for the whole Andaman coast, including onward boats to Phi Phi and Krabi.

Chiang Mai is the main gateway to northern Thailand and, on current traffic data, the country’s fourth-busiest airport, not the ninth or the second as some older lists claim. It is unusually close to the city, barely 15 minutes from the Old City moat, so a red songthaew or a Grab is quick and cheap. Domestic and international terminals connect under one roof. It handles regional international routes and is the launch point for Pai, Chiang Rai and the northern hills.

Krabi is the calmest way into the Andaman coast if you want to skip Phuket’s crowds. It is about 15 km from Krabi town, with daily flights from Bangkok, Kuala Lumpur and Singapore. From arrivals, shared minivans and metered taxis run straight to Ao Nang, the Railay pier and the Koh Lanta ferry. Separate domestic and international terminals, ATMs and a Subway keep it simple.

Hat Yai is the commercial hub of the deep south, close to the Malaysian border, so it draws a steady Malaysian and Singaporean crowd alongside domestic traffic. Public buses and taxis wait outside arrivals for the short run into Hat Yai town. It is better equipped than its size suggests, with currency exchange, ATMs, prayer rooms for both Muslim and Buddhist travellers, a spa and the Royal Orchid business lounge.

Samui is privately built and run by Bangkok Airways, and it is regularly named among the prettiest airports anywhere: open-sided wooden pavilions, tropical gardens and buggies instead of jet bridges. Because one airline owns it, fares run higher than the ferry route through Surat Thani, but you land minutes from Chaweng and Bophut. Direct flights connect Bangkok, Phuket, Singapore and Kuala Lumpur.

Surat Thani is the budget traveller’s back door to the Gulf islands. It is about 21 km from town and it is the cheapest way to reach Koh Samui, Koh Phangan and Koh Tao. Fly in on a low-cost carrier, then take the combined bus-and-ferry ticket most airlines sell. It shares the field with a Royal Thai Air Force base. Slower than flying into Samui, but often a fraction of the price.

Mae Fah Luang is northern Thailand’s second international airport, about 10 km from Chiang Rai city. It is an AOT-run gateway for the far north, handy for the White Temple, the Golden Triangle and the tea hills around Doi Mae Salong. Local buses, taxis and tuk-tuks from gate 3 handle the short run into town, and there are two currency counters, a spa and a meditation room.

Udon Thani is the main gateway to Isan, Thailand’s northeastern region, and the usual jumping-off point for the crossing to Vientiane in Laos, about an hour north. Frequent domestic flights link it to Bangkok. It doubles as a Royal Thai Air Force base and, for now, stays under the Department of Airports rather than AOT after a planned transfer was postponed in 2025.

U-Tapao is Pattaya’s international airport, midway between Pattaya and Rayong on the eastern Gulf coast and operated by the Royal Thai Navy. A single terminal handles both domestic and international flights, with links to Phuket, Koh Samui, Chiang Mai, Hat Yai and Udon Thani inside Thailand, plus Kuala Lumpur, Singapore and several Chinese cities. If you are heading to Pattaya or Koh Samet, this is your airport, not Bangkok.
