Planning a trip to Thailand comes with a delightful problem: there are too many incredible places to start. Bangkok’s street food and skyline? Islands and turquoise water? Misty mountains and temple-hopping up north?
If there’s one decision that sets the tone (and the budget) for the rest of your trip, it’s your flight itinerary—specifically, which Thailand airport you fly into.
Before we dive in, a quick “still open?” check: all airports covered below are currently active and operating, managed by Thailand’s major airport operators (Airports of Thailand for the big gateways, Bangkok Airways for Koh Samui, and the Department of Airports for Krabi).
So… which is the best airport to fly into Thailand?
Here’s the simplest answer:
- Best all-around (especially for first-timers): Suvarnabhumi Airport (BKK), Bangkok Airports of Thailand
- Best for budget flights & low-cost carriers in Bangkok: Don Mueang (DMK) donmueang.airportthai.co.th
- Best if you want beaches immediately: Phuket (HKT) or Krabi (KBV) Phuket International Airport
- Best for Koh Samui (and nearby islands): Samui (USM) Bangkok Airways
- Best for mountains, cafes, and temples up north: Chiang Mai (CNX) chiangmai.airportthai.co.th
- Best for Chiang Rai + the White Temple region: Chiang Rai (CEI) chiangrai.airportthai.co.th
Now let’s match the airport to the kind of trip you actually want.
Quick cheat sheet: choose your airport based on your first destination
Choose Bangkok (BKK or DMK) if you…
- Want the most flight options (especially long-haul international routes)

- Are okay paying a bit more for convenience (Samui flights can be pricier)
- Plan to ferry onward to Koh Phangan or Koh Tao
Choose Chiang Mai (CNX) if you…

- Plan to road trip into northern Thailand chiangmai.airportthai.co.th
Choose Chiang Rai (CEI) if you…
- Want the White Temple (Wat Rong Khun) and Golden Triangle region early
- Prefer quieter northern Thailand right away
City seekers: flying into Bangkok
Bangkok is still the classic entry point—especially for long-haul travelers—because it’s built for connections. The city is served by two major airports, and choosing the right one can save you real money (and real stress).
Suvarnabhumi International Airport (BKK) — best for long-haul + major airlines
BKK is Bangkok’s primary international hub and the most common arrival point for flights from North America, Europe, and many long-haul routes.
Getting into the city from BKK
- Airport Rail Link (ARL): A fast, traffic-proof option. The ARL operates daily (early morning to midnight) per the airport’s transportation info. Suvarnabhumi Airport
- Typical fares are distance-based (often cited as 15–45 THB).
- Nice 2025/2026 update: ARL has also rolled out contactless EMV tap-to-pay (helpful if you’re arriving without cash).
- Taxi / rides: Convenient, but Bangkok traffic can turn a short ride into a sweaty saga. Expect added tolls in some cases.
When BKK is the best move
- You’re arriving long-haul and want the smoothest immigration + connection setup
- You want to connect onward to another region the same day
- You don’t want to gamble with separate-ticket airport transfers
Don Mueang International Airport (DMK) — best for budget airlines + cheap domestic hops
DMK is Bangkok’s budget-friendly airport and a favorite for low-cost carriers and many regional flights.
Getting into Bangkok from DMK (updated transport details)
DMK has clearly listed public bus options, including:
- A1: DMK ↔ BTS Chatuchak / Mo Chit area (30 THB)
- A2: DMK ↔ Victory Monument (30 THB)
- A3: DMK ↔ Pratunam / Ratchaprasong / Lumpini (50 THB)
- A4: DMK ↔ Democracy Monument / Khaosan Road area (50 THB) donmueang.airportthai.co.th
Free shuttle between DMK and BKK
If you’re connecting between Bangkok airports, DMK also notes a free airport shuttle bus (ticketed passengers only) with service listed from 05:00–24:00. donmueang.airportthai.co.th
When DMK is the best move
- You found a significantly cheaper international flight into DMK
- You’re planning a budget-heavy trip and want cheap domestic connections
- You’re doing a quick Bangkok stop before heading elsewhere
Pro tip: If your international flight arrives at BKK and your domestic flight leaves from DMK (or vice versa), leave a generous buffer. Bangkok is wonderful, but it does not hurry.
Beach lovers: flying into southern Thailand
Thailand’s southern coast is split into two main “beach personalities”:
- Andaman Sea (west): Phuket, Krabi, Phi Phi, Koh Lanta — dramatic cliffs and iconic turquoise water
- Gulf of Thailand (east): Koh Samui, Koh Phangan, Koh Tao — softer beaches and easy island-hopping
Phuket International Airport (HKT) — best for maximum beach infrastructure
Phuket is one of the easiest places in Thailand to land and immediately slip into vacation mode.
Getting around from HKT (helpful official transport notes)
Phuket’s airport information includes:
- An airport bus with posted operating hours (airport → city and city → airport schedules)
- An Airport Bus Express route serving Patong Beach with listed operating hours
- The Phuket Smart Bus option for beach-hopping routes across multiple popular beaches Phuket International Airport
When HKT is the best move
- Phuket is your main destination
- You want easy access to tours, nightlife, and loads of accommodation
- You want lots of transport choices without figuring out transfers on day one
Krabi International Airport (KBV) — best for Ao Nang, Railay, and a calmer base
If your dream itinerary includes limestone cliffs, longtail boats, and a slightly slower pace, Krabi is a fantastic starting point.
Krabi International Airport (KBV) is a public airport operated by Thailand’s Department of Airports, and it remains an active gateway to the Andaman region.
When KBV is the best move
- You want to base yourself in Ao Nang or visit Railay Beach
- You want quicker access to Koh Lanta than coming via Phuket
- You prefer a less “mega-touristy” arrival experience than Phuket
Island lovers: flying into Koh Samui (USM)
Samui International Airport (USM) — best for starting on a postcard-perfect island
Koh Samui’s airport is famous for being charmingly open-air and tropical—basically the opposite of a fluorescent-lit airport dungeon.
Important update/correction from many older articles: Samui Airport is privately operated by Bangkok Airways, not Thai Airways.
When USM is the best move
- Samui is your #1 destination and you don’t want to add ferry logistics immediately
- You’re connecting onward to Koh Phangan (Full Moon Party travelers, hello) or Koh Tao
Budget reality check: Flights to Samui can be noticeably more expensive than flying into Surat Thani (URT) and taking a ferry, but you’re paying for convenience and time saved.
Mountain enthusiasts: flying into Northern Thailand
Northern Thailand is where many travelers fall in love with the country: cooler evenings, mountain viewpoints, craft coffee culture, night markets, and temples that feel like stepping into a painting.
Chiang Mai International Airport (CNX) — best all-around northern gateway
Chiang Mai is the easiest “north first” arrival point and a great base for day trips, temple routes, and nature.
CNX’s official transport info highlights multiple options, including city bus service hours and airport shuttle routes with posted fares. chiangmai.airportthai.co.th
When CNX is the best move
- You want northern Thailand right away
- You’re planning to also visit Pai, Chiang Dao, or Doi Inthanon
- You like a mix of culture + nature without going too remote
Chiang Rai International Airport (CEI) — best for Chiang Rai + the White Temple
If your must-do list includes Wat Rong Khun (the White Temple), flying into Chiang Rai (CEI) keeps things simple. chiangrai.airportthai.co.th
Transport note: CEI’s airport info emphasizes car/taxi/shuttle options, which is common in smaller Thai airports. chiangrai.airportthai.co.th

Is it cheaper to fly into Bangkok or Phuket?
On average, Bangkok is often cheaper because it’s a massive hub with more airline competition and more route options. Phuket can be a little pricier internationally—especially in peak season—though deals absolutely happen.
A money-saving strategy many travelers love:
- Fly into Bangkok (BKK or DMK) on the best long-haul fare
- Book a separate domestic hop to Phuket or Krabi
Just watch your connection timing if you’re switching airports or booking separate tickets.
