Thailand has nine airports, and the right one to fly into depends on where your trip actually begins. Most of the confusion around Thailand airports starts in Bangkok, where two separate airports serve the same city and different carriers divide between them without a clear pattern. Beyond Bangkok, the structure is more straightforward: the south divides between the Andaman coast and the Gulf of Thailand, each with its own gateways, and the north is served almost entirely through Chiang Mai International Airport.
This guide covers every Thailand airports by code and function, the BKK vs DMK question in full, which island gateways are worth the fare premium, and the direct routes available from India.
Thailand covers three genuinely different kinds of travel within one country: the temple cities of the north, the island chains of the south, and Bangkok as both a destination and the main arrival point for most international flights.
Understanding that geography is what makes the airport question easier to answer. For Indian travellers, our Thailand tour packages are built around the right gateways from the start, with fixed departures and everything handled end to end.
The Complete Thailand Airports Directory
Thailand spreads across three very different kinds of travel in one country: the temple cities of the north, the island chains of the south, and Bangkok sitting between them as both a destination and a transit hub. Understanding that geography is what makes the airport question easy to answer.
Our Thailand tourism guide covers the country from end to end, providing a complete picture of where each region fits and what it offers.
How Many International Airports in Thailand?
Bangkok Has Two Airports and They Are Not the Same
Bangkok Airports BKK vs DMK: What Actually Separates Them
Bangkok has two Thailand airports and they are not interchangeable. Which one you arrive at depends entirely on which carrier you book, and confusing them on a connecting itinerary is one of the more expensive mistakes a first-time visitor to Thailand can make.
Understanding the difference between Bangkok airports BKK vs DMK before you book saves considerable trouble on arrival
- Suvarnabhumi Airport (BKK): Is Bangkok's primary international hub, opened in 2006, and handles the majority of long-haul and full-service traffic. The Airport Rail Link connects the terminal to Phaya Thai station in central Bangkok in roughly 30 minutes. Thai Airways, Bangkok Airways, Emirates, Singapore Airlines, and most Indian carriers use BKK. The terminal is large, the signage is clear, and immigration queues move predictably outside peak arrival windows.
- Don Mueang Airport (DMK): Is the older of the two, located about 24 kilometres north of the city centre with no rail connection. AirAsia, Nok Air, and Lion Air operate the majority of their routes from here. Taxis and the A1 and A2 bus routes are the main transfer options into the city, and journey times vary considerably with traffic. The terminal is functional but smaller, and domestic connections make up a significant share of its volume.
DMK Airport: What to Know Before You Land
DMK airport handles a significant share of Bangkok's budget and domestic traffic, and first-time visitors often underestimate how different the arrival experience is from BKK.
- Transferring between BKK and DMK: Is where itineraries come apart. The two airports are roughly 30 kilometers apart, and the road between them runs through Bangkok's northern traffic. Allow a minimum of three hours between a BKK arrival and a DMK departure, and more during peak hours or when the expressway is congested. Airlines booking you on a BKK to DMK connection will not coordinate your transfer. That is your responsibility to plan.
BKK or DMK: Which Airport Should You Book?
If you are on a full-service carrier or arriving from outside the region, BKK is almost certainly where you will land. DMK is the default for budget carriers operating within Southeast Asia and for most domestic connections. Check your ticket before assuming, because the two airports are 30 kilometres apart and the transfer between them is your responsibility, not the airline's.
Phuket, Krabi, and Samui: The Southern Airport Guide
The south is where most first-time visitors to Thailand spend the majority of their trip, and it has three distinct Thailand airport options depending on which coast and which islands you are heading to.
Getting the arrival point right here matters more than anywhere else in the country because the wrong choice can add hours of road and ferry time to the start of your holiday.
Phuket Airport (HKT)
Phuket airport code HKT is the IATA identifier you will see on all booking platforms when searching for flights to the Andaman coast. Phuket International Airport sits at the northern tip of the island, roughly 45 minutes by road from Patong and an hour from the southern beaches.
The descent over the Andaman is one of the more visually striking approaches in the region. Direct connections run from Bangkok, several Indian cities, Singapore, Kuala Lumpur, and a growing number of European hubs.
If your trip focuses on the Andaman Islands, flying directly into HKT and skipping Bangkok is usually the best option. Travellers planning to move between Phuket and Krabi should read our guide on how to reach Krabi from Phuket before deciding which airport to arrive at and which to depart from.
Which is the Nearest Airport to Krabi?
Krabi Airport (KBV)
Krabi International Airport serves Ao Nang, Railay Beach, and Koh Lanta, sitting about 15 kilometers from Ao Nang and 20 kilometers from Krabi town. It is the quieter and more convenient arrival point for the eastern Andaman coast, with transfers into Ao Nang taking around 20 minutes and an overall arrival experience considerably less chaotic than Phuket. If your stay is centered on the Krabi area, this is the right airport.
Phuket Airport (HKT) is only relevant if your itinerary includes both coasts or a combination of Phi Phi and Krabi. In that case, arriving at HKT and departing from KBV on an open-jaw ticket is the most efficient structure, though at around 160 kilometers from Krabi town it is not worth the detour otherwise.
Koh Samui Airport (USM)
Koh Samui Airport airlines are operated exclusively by Bangkok Airways, which holds the private concession on the terminal and controls all scheduled services.
Koh Samui's airport is privately operated by Bangkok Airways, which holds the exclusive concession and sets fares without market competition. The open-air terminal is pleasant and the island setting makes it one of the more atmospheric arrivals in the country, but the fare premium is real and should factor into your planning.
The budget alternative is flying into Surat Thani Airport on the mainland and taking the ferry across to Samui. The combined journey takes two to three hours longer but saves a meaningful amount on a group booking. If you have the time, it is worth running the numbers.
Chiang Mai, Chiang Rai, and the Case for the Sleeper Train
The northern Thailand airports serve a different kind of trip from the south. Chiang Mai is the main arrival point for anyone heading into the hills, the old city, or the wider Chiang Rai and Golden Triangle region, and it handles the bulk of northern traffic among all Thailand airports. For travellers with time on their side, the overnight sleeper train from Bangkok is worth serious consideration before booking a domestic flight.
Chiang Mai Airport (CNX)
Chiang Mai International Airport is the main gateway to northern Thailand and handles direct connections from Bangkok, several regional hubs, and a small number of international routes. The airport sits close to the old city and most hotels are within 20 to 30 minutes of the terminal.
The alternative worth knowing about is the overnight sleeper train from Hua Lamphong station in Bangkok, which reaches Chiang Mai in roughly 11 to 13 hours and is genuinely comfortable in first or second class. If your Bangkok departure is in the evening and you want to save a night's accommodation, it is a practical option the flight cannot match on experience. Our guide to how to reach Chiang Mai from Bangkok covers the full comparison.
Chiang Rai Airport (CEI)
Chiang Rai International Airport handles primarily domestic routes from Bangkok and sees a fraction of Chiang Mai's traffic. Most travellers visit Chiang Rai as a day trip or overnight extension from Chiang Mai rather than flying in directly, which usually makes more logistical sense unless the trip begins in the far north.
How to Pick the Right Arrival Airport for Your Thailand Itinerary
The right Thailand airports depends almost entirely on where your itinerary starts and ends, not just which city you land in.
- Bangkok only: Book whichever airport your carrier uses. BKK for most international arrivals, and DMK if you are on AirAsia or a budget routing from within the region.
- Islands first: Fly directly into HKT for Phuket and the Andaman, KBV for the Krabi coast, or USM if the fare premium on Samui works for your budget. Avoiding Bangkok on an island-first itinerary saves a full transit day.
- North loop: Fly into CNX and out of BKK, or reverse it. The sleeper train between the two is worth building into the itinerary if time allows.
- Full-country open-jaw: The most efficient structure for a two-week Thailand trip is usually a BKK arrival and HKT or CNX departure, depending on whether you end in the south or the north. Returning to Bangkok only to fly out wastes roughly a day.
Check the best time to visit Thailand before finalizing your routing, since shoulder and peak seasons affect both flight availability and island ferry schedules.
Direct Flights to Thailand from India: Routes and Carriers
Direct routes connect four Indian cities to Suvarnabhumi. Delhi, Mumbai, Kolkata, and Bengaluru all have regular services on IndiGo, Air India, and Thai Airways, with flight times ranging from three and a half to five hours depending on the origin. Phuket also receives direct flights from Delhi and Mumbai on select carriers, making an Andaman-first itinerary viable without a Bangkok stopover.
Verify current carrier schedules at the time of booking, as seasonal capacity on India-Thailand routes changes frequently. Our guide on how to go Thailand from India covers the full details about flights, carriers, and entry requirements before you get to the airport question.
After You Land: SIM, Forex, Grab, and Immigration
- Immigration and TDAC: Thailand requires the Thailand Digital Arrival Card for most international arrivals. Complete it before landing to avoid filling in a paper form at the immigration desk. Our guide to the Thailand visa for Indians covers the current entry requirements, visa-on-arrival process, and exemptions in full.
- SIM cards: Available at counters immediately after immigration at BKK, DMK, HKT, and CNX. AIS and DTAC both offer tourist SIMs with 15 to 30-day validity. Pick one up before exiting the arrivals hall.
- Forex: Exchange counters are available airside and in the arrivals hall at all major airports. Rates at BKK and HKT are reasonable on arrival. SuperRich and Vasu Exchange in Bangkok city offer better rates if you can wait until you reach the city.
- Grab and taxis: Grab operates designated pickup zones at BKK, DMK, HKT, and CNX. The pickup point is always separate from the metered taxi queue and is signposted from the arrivals hall. Metered taxis are reliable at BKK. At smaller airports, confirm the meter is running before the journey begins.
