Thailand is served by dozens of full-service and low-cost airlines, but the best option depends on where you are starting, which part of Thailand you plan to visit, and whether you value a low base fare or an easier connection. Bangkok has two major airports, while Phuket, Chiang Mai, Krabi, and Koh Samui can also be useful arrival points.
Quick Answer
Major airlines flying into Thailand include Thai Airways, Emirates, Qatar Airways, Singapore Airlines, Cathay Pacific, EVA Air, Korean Air, British Airways, United Airlines, AirAsia, Thai Lion Air, Nok Air, Bangkok Airways, and Vietjet Thailand. Most long-haul flights use Bangkok Suvarnabhumi, while many low-cost regional flights use Don Mueang.
Key Takeaways
- Suvarnabhumi Airport (BKK) is Bangkok’s main long-haul and full-service international gateway.
- Don Mueang Airport (DMK) handles many low-cost domestic and regional flights, including services from Thai AirAsia, Nok Air, and Thai Lion Air.
- Phuket receives many direct international flights and can save time when a beach holiday is your main goal.
- Thai Airways and Bangkok Airways usually provide a more inclusive experience, while low-cost airlines may charge separately for baggage, meals, and seat selection.
- Thai Smile no longer operates. Its flights and aircraft were integrated into Thai Airways, with full cessation taking effect on January 1, 2024.
- United Airlines operates a direct Los Angeles–Bangkok service via Hong Kong. It includes a stop and is not a nonstop flight.
Updated: Airline routes, frequencies, baggage allowances, and fare inclusions can change by season. The information below was reviewed on July 25, 2026, but you should confirm the exact flight and airport before paying.
Which Airlines Fly Into Thailand?
Thailand receives flights from airlines based throughout Asia, Europe, the Middle East, Australia, and North America. The following table gives representative examples rather than an exhaustive route list.
| Region or Travel Type | Examples of Airlines Serving Thailand | Common Thai Gateways |
| Thai domestic and regional travel | Thai Airways, Bangkok Airways, Thai AirAsia, Nok Air, Thai Lion Air, and Vietjet Thailand | BKK, DMK, HKT, CNX, KBV, and USM |
| Southeast Asia | Singapore Airlines, Scoot, Malaysia Airlines, AirAsia, Vietjet Air, Cebu Pacific, and Bangkok Airways | BKK, DMK, HKT, CNX, and other regional airports |
| East and Northeast Asia | Cathay Pacific, EVA Air, China Airlines, Korean Air, Asiana Airlines, ANA, Japan Airlines, Air China, and China Southern | Primarily BKK and HKT, with selected regional services |
| Middle East | Emirates, Qatar Airways, Etihad Airways, Air Arabia, and Oman Air | BKK and HKT |
| Europe | British Airways, Lufthansa, Austrian Airlines, SWISS, Finnair, Turkish Airlines, and other scheduled or seasonal carriers | Mainly BKK, with selected direct Phuket flights |
| North America | United Airlines, Air Canada, and connecting options on EVA Air, Cathay Pacific, Korean Air, ANA, Japan Airlines, Emirates, Qatar Airways, and Singapore Airlines | Primarily BKK |
| Australia and nearby markets | Thai Airways, Qantas, Jetstar, and connecting Asian carriers | BKK and HKT |
The official Suvarnabhumi Airport airline directory is useful for checking which carriers currently maintain operations at Bangkok’s primary international airport. Being listed at an airport does not guarantee that a particular route operates every day or throughout the year.
Main Airports for Flights Into Thailand
Your arrival airport can matter as much as your airline. A cheap ticket to the wrong Bangkok airport may become inconvenient if you have a separate connection.
| Airport | Best For | What to Know |
| Suvarnabhumi Airport (BKK) Bangkok |
Long-haul flights, full-service airlines, and international connections | This is Bangkok’s main international gateway and a hub for Thai Airways. It is connected to central Bangkok by the Airport Rail Link. |
| Don Mueang International Airport (DMK) Bangkok |
Low-cost domestic and regional flights | Thai AirAsia, Nok Air, Thai Lion Air, and several regional carriers operate here. It is a separate airport from BKK. |
| Phuket International Airport (HKT) Phuket |
Phuket, Khao Lak, and Andaman Coast holidays | Phuket receives domestic flights and many direct international services, including scheduled and seasonal routes. |
| Chiang Mai International Airport (CNX) Chiang Mai |
Northern Thailand | Useful for Chiang Mai and nearby northern destinations. It has domestic flights and selected international routes within Asia. |
| Krabi International Airport (KBV) Krabi |
Krabi, Ao Nang, Railay, and nearby islands | It has domestic and selected international flights, but the route network is smaller and more seasonal than Bangkok or Phuket. |
| Samui International Airport (USM) Koh Samui |
Koh Samui, Koh Phangan, and Koh Tao connections | Bangkok Airways operates many of the airport’s services. Flights can cost more than flying to Surat Thani and continuing by road and ferry. |
Warning: Suvarnabhumi Airport (BKK) and Don Mueang Airport (DMK) are separate airports on different sides of Bangkok. A connection that requires changing airports is not a normal terminal transfer. Allow a generous buffer for immigration, baggage collection, traffic, check-in, and security.
Thai Airways
Thai Airways is Thailand’s national flag carrier and the country’s main full-service airline. Its network includes domestic destinations and routes across Asia-Pacific, Europe, and Australia, although individual destinations and frequencies change by season.
Thai Airways is often a practical option when you want a long-haul flight and a domestic connection on one itinerary. A protected through-ticket can make baggage handling and disruption management easier than combining unrelated airlines on separate bookings.
Service inclusions depend on the cabin and fare, but checked baggage, meals, and in-flight entertainment are normally more likely to be included than on a basic low-cost fare. Members of the Royal Orchid Plus program can earn and redeem miles on eligible Thai Airways flights and partner services.
Pro Tip: When connecting from an international Thai Airways flight to a Thai domestic destination, compare a single through-ticket with two separate bookings. The through-ticket may cost more, but it can provide better protection if the first flight is delayed.
Bangkok Airways
Bangkok Airways describes itself as “Asia’s Boutique Airline” and is especially useful for destinations that do not have as much competition from other carriers. Its network commonly includes Bangkok, Koh Samui, Sukhothai, Trat, Chiang Mai, Phuket, and selected international cities in nearby countries.
The airline also operates or is associated with the airports at Koh Samui, Sukhothai, and Trat. This gives it an important role in reaching islands and smaller leisure destinations. Its official company profile provides current corporate and network information.
Bangkok Airways fares generally offer a more inclusive experience than the lowest low-cost fares. Checked baggage and an in-flight meal may be included, while eligible passengers can use its airport lounges at participating locations. Always check the specific fare because inclusions and lounge availability can vary.
AirAsia
| AirAsia Basics | Traveler Information |
| Carrier family | Thai AirAsia, Thai AirAsia X, and other AirAsia affiliates may sell Thailand routes. |
| Common airport | Many Bangkok services use Don Mueang (DMK), but selected flights use Suvarnabhumi (BKK), Phuket, Chiang Mai, and other airports. |
| Fare model | Low base fare with optional or bundled checked baggage, meals, seat selection, priority services, and other extras. |
| Best for | Budget-conscious domestic and regional travel, especially when you can travel light. |
| Check before paying | Airport code, baggage allowance, meal inclusion, seat fee, payment fee, and change conditions. |
AirAsia is one of the best-known low-cost airline groups in Asia and offers numerous domestic and international options involving Thailand. Its current Thailand booking page lists destinations such as Bangkok, Phuket, Chiang Mai, Krabi, Hat Yai, Chiang Rai, Khon Kaen, Udon Thani, and Surat Thani.
The main advantage is the ability to pay for only the services you need. The final cost can rise once you add checked baggage, a preferred seat, food, insurance, and flexibility, so compare the checkout total rather than the first advertised fare. You can review current destinations through the official AirAsia Thailand flight page.
Nok Air
Nok Air is a Thai low-cost airline based at Don Mueang Airport. It is most useful for domestic travel between Bangkok and Thai cities such as Chiang Mai, Chiang Rai, Phuket, Hat Yai, Udon Thani, Surat Thani, and other provincial destinations when those routes are operating.
Nok Air’s network has changed over time, so older articles that describe a broad international network may not reflect the current schedule. Search the airline’s live booking engine for your exact dates rather than relying on a historic destination list.
As with other low-cost carriers, compare the fare package carefully. Checked baggage, seat selection, flexibility, and other services can depend on the fare type rather than being included with every ticket.
Thai Lion Air
Aircraft and Cabin Setup
Thai Lion Air’s official aircraft page lists Boeing 737-800 and Boeing 737-900ER configurations. Seating layouts and onboard services can vary by aircraft and route, so check the flight details rather than assuming that every aircraft has the same cabin.
Domestic and International Connectivity
The airline serves domestic destinations from Bangkok Don Mueang and publishes international routes to parts of China, India, Indonesia, Japan, Malaysia, Nepal, Singapore, South Korea, and Taiwan. Routes may be added, suspended, or operated only during certain seasons. Check the official Thai Lion Air route map for the latest available destinations.
Fare and Baggage Differences
Thai Lion Air offers different fare types, and the checked-baggage allowance depends on the route and fare. Some promotional fares may include no checked baggage, while other fares or routes include a stated allowance. Review the current baggage policy before booking.
Vietjet Thailand
Vietjet Thailand is another important low-cost option for domestic and international travel. It operates many services from Suvarnabhumi Airport rather than Don Mueang, which can make it more convenient when you are connecting with a long-haul flight at BKK.
Its domestic network includes destinations such as Chiang Mai, Chiang Rai, Phuket, Krabi, Surat Thani, Hat Yai, Khon Kaen, Ubon Ratchathani, and Udon Thani. International destinations vary by schedule and have included cities in Japan, South Korea, Taiwan, China, Vietnam, Cambodia, and India.
Check the airline’s official airport and terminal information because some Vietjet-branded flights may be operated under different carrier codes or use different terminals.
Thai Smile Is No Longer Operating
Thai Smile Airways launched in 2012 as a regional subsidiary of Thai Airways, but it is no longer an active airline. Thai Smile officially merged into Thai Airways on December 31, 2023, and full cessation of its operations took effect on January 1, 2024.
The integration transferred 20 Airbus A320-200 aircraft into the Thai Airways fleet. Travelers who find older recommendations for Thai Smile should now search Thai Airways for the corresponding domestic or regional route. The change is documented in the official Thai Airways timeline.
Full-Service vs. Low-Cost Airlines in Thailand
| Feature | Full-Service Airline | Low-Cost Airline |
| Typical examples | Thai Airways, Singapore Airlines, Emirates, Qatar Airways, Cathay Pacific | AirAsia, Nok Air, Thai Lion Air, Vietjet Thailand, Scoot |
| Base fare | Usually higher but may include more services | Usually lower before optional extras |
| Checked baggage | Often included, depending on fare and route | Frequently sold separately or included only in a bundle |
| Food and drinks | Often included on longer flights | Often optional or available for purchase |
| Connections | More likely to offer protected connections and partner-airline itineraries | Often designed for point-to-point travel; self-transfers may be required |
| Best choice when | You have baggage, a long journey, or a connection you want protected | You can travel light and the schedule and airport are convenient |
These are general differences, not universal rules. Some full-service economy fares exclude checked baggage, while some low-cost bundles include baggage, food, and seat selection.
Tips for Choosing the Right Airline for Your Trip
Compare the Final Price
Do not compare only the first fare shown in search results. Add checked baggage, cabin-bag upgrades, seat selection, meals, payment charges, and travel between the airport and your accommodation. A full-service ticket can sometimes cost less than an upgraded low-cost booking.
Check the Airport Code
Bangkok search results may include both BKK and DMK. Make sure the airport matches your accommodation or connecting flight. Phuket, Chiang Mai, Krabi, and Koh Samui may also provide a more direct route to your final destination than flying through Bangkok.
Protect Important Connections
A single itinerary normally provides more protection than two separate tickets. With separate tickets, the second airline may treat you as a no-show if the first flight is delayed, even when both flights appear together in a third-party search result.
Review the Baggage Rules
Check both weight and size limits. Pay special attention when moving from a long-haul airline to a low-cost domestic carrier because the second airline may have a lower cabin-bag allowance.
Check Change and Cancellation Conditions
The lowest fare may be nonrefundable or expensive to change. A slightly higher fare can be worthwhile when your plans are uncertain, especially during monsoon disruptions, holiday periods, or complex multi-city trips.
Consider Flight Frequency
An airline with several flights per day may offer better recovery options after a cancellation than an airline serving the route only a few times per week. This can matter more than a small fare difference.
Plan Family Travel Before Booking
Families should review seating rules, infant baggage, stroller handling, and airport transfer time before selecting a fare.

Pro Tip: Search for flights to your final region first, not just Bangkok. A direct flight to Phuket, Chiang Mai, Krabi, or Koh Samui may cost more upfront but save a hotel night, an airport transfer, or a full day of travel.

Are there direct flights from the United States to Thailand?
United Airlines began daily Los Angeles–Bangkok service on October 26, 2025, but the flight operates via Hong Kong. It is therefore a direct one-stop service, not a nonstop flight. No scheduled nonstop U.S.–Thailand passenger route was identified in the official sources reviewed on July 25, 2026. Other common one-stop hubs include Taipei, Tokyo, Seoul, Hong Kong, Singapore, Doha, and Dubai.
What are the main international airports in Thailand?
Suvarnabhumi Airport is the main long-haul gateway. Don Mueang is a major low-cost and regional hub. Phuket is an important international tourist gateway, while Chiang Mai, Krabi, Koh Samui, Hat Yai, Chiang Rai, and U-Tapao handle smaller international networks.
Are BKK and DMK the same airport?
No. BKK is Suvarnabhumi Airport, while DMK is Don Mueang Airport. They are separate airports in different parts of Bangkok. A transfer between them requires ground transportation, baggage collection when applicable, and a new check-in unless your airline provides a specific transfer arrangement.
Is Thai Smile still operating?
No. Thai Smile merged into Thai Airways on December 31, 2023, and stopped operating on January 1, 2024. Search Thai Airways for domestic and regional services that older travel guides may attribute to Thai Smile.
Which airline is best for Koh Samui?
Bangkok Airways operates many flights to Koh Samui and is often the most convenient option. Thai Airways may sell connecting itineraries that include a Bangkok Airways-operated segment. A cheaper alternative can be flying to Surat Thani or Nakhon Si Thammarat and continuing by road and ferry, but the trip takes longer.
