Your questions about flights to Thailand, answered

Find helpful route details based on KAYAK data, including flight times, airports, airlines and booking questions.

  • Is now a good time to book a flight to Thailand?

    Yes. Fares to Thailand are low right now. As a rule of thumb, a round-trip under $866 (cheaper than most fares this year) is a good deal, so if you spot one at or below that, it's worth booking.

  • How much should I budget for a flight to Thailand?

    You can typically expect round-trip fares to Thailand to cost from $866 to $1,402, based on KAYAK data from the past 12 months.

  • What are the main airports serving Thailand?

    Thailand has 33 airports. The three busiest are Bangkok Suvarnabhumi (BKK) (84% of arrivals), Phuket City (HKT) (9%) and Chiang Mai (CNX) (6%).

    Based on the flight schedule for the next 3 months, no airline operates nonstop flights to Thailand on a regular basis. One-stop options include:

    • United Airlines
    • EVA Air
    • Delta

  • Is it cheaper to fly with a layover to Thailand?

  • Do US citizens need a visa to travel to Thailand?

    No, US citizens do not need a visa for Thailand. There is a list of 64 countries that are exempt under the Visa Exemption Rule for entry to Thailand, so you should check online to see if your country is on the list. If it is, you will need to apply for a visa.

  • Is it recommended to buy local currency once I arrive in Thailand?

    Thai Baht is the currency used in Thailand and unless you acquire some before you take your flight from the US to Thailand, it is definitely recommended that you buy some notes upon arrival in the country to take care of transportation costs or to rent a car if you intend to drive while on vacation.

  • Can I get a nonstop flight to Krabi from the US?

    Unfortunately, there are no nonstop flights available from any airports in the United States to Thailand. If Krabi is your ultimate destination, your best bet is to book a flight to either Suvarnabhumi Airport or Don Mueang Airport in Bangkok and then get a connecting flight to Krabi International Airport (KBV).

  • Where should I fly to enjoy some festivals in Thailand?

    You can attend the Samui Regatta in the Gulf of Thailand with a connecting flight out of Bangkok to Samui Airport (USM). Another unique and popular event is the Rocket Festival (Boon Bang Fai) in Yasothorn province. If you don’t wish to drive, take a connecting flight from Bangkok to Ubon Ratchathani Airport (UBP) and arrange transportation from there.

  • What child seat laws do I need to be aware of to rent a car in Thailand?

    Any youngster under the age of 7 must ride in the rear of the vehicle in a child seat that has been properly installed. To ride in the front seat of a vehicle, any child under the age of 12 should be securely buckled into a child safety seat. Because kids can only ride in the back seat of a taxi, taxis are exempt from such car seat regulations in Thailand.

  • What other cities are reachable from Suvarnabhumi Airport (BKK) once I arrive at this airport?

    When traveling to Thailand from several international airports in the US, travelers can conveniently visit close-by cities to Suvarnabhumi Airport. From BKK, it is simple to go to a number of close-by cities, including Bang Bo, Samut Prakan, Phra Pradaeng, Lam Luk Ka, and Bangkok. After arriving at BKK, you have the option of boarding a public bus service, using a taxi, and renting a car.

  • Which airport lounges are preferred among economy travelers flying from the USA to Thailand?

    Airport lounges are typically thought of as one of the greatest places to unwind while passengers wait for their flights from the United States to Thailand. The majority of travelers in economy prefer to fly from the US to Thailand through Salt Lake City International Airport (SLC). Before taking off, passengers can affordably unwind in the Delta Sky Club at the SL Airport.

  • For the SWF-BKK route to Thailand, how can I catch the first flight at SWF Airport?

    The best method to take the earliest flight from SWF Airport to Thailand is to stay at a nearby hotel. One option that needs to be considered in this case is the Homewood Suites by Hilton Newburgh-Stewart Airport. Travelers can easily walk 0.6 miles to SWF Airport before boarding their flight to Thailand.

Your guide to booking flights to Thailand

Get tips on when to book, when to fly and what to know before your trip.
  • If you can plan ahead, the sweet spot for booking your flight is 12 weeks before your trip. KAYAK data shows fares in this window are around 10% lower than last-minute bookings (made within 2 weeks of departure). Not ready to commit? Set a Price Alert and we'll let you know when prices change.
  • If your dates are flexible, February usually has the best deals, while December tends to be the priciest. The best-time-to-travel chart on this page shows how prices move across the year.
  • Tuesday is usually the cheapest day to fly, about 9% cheaper than Saturday, the priciest day. If your dates are flexible, that's an easy way to save. If not, try nearby airports or a layover instead.
  • If you're looking to save, Bangkok Suvarnabhumi (BKK) has had the lowest fares over the past 12 months. Just remember to factor in the cost of getting to your final destination.
  • Bangkok is the most popular destination in Thailand. Start your trip here and then check out these other places KAYAK travelers love: Pattaya, Phuket City and Chiang Mai.
  • Consider a layover to Thailand, it can cost less than flying nonstop. Guangzhou Baiyun (CAN) is typically the cheapest place to connect.
  • Thailand has over 10 international airports because it is surrounded by several countries and due to its unique geography. Flights originating from the US to the country will arrive at one of three airports: Suvarnabhumi International Airport (BKK) and Don Mueang International Airport (DMK), both in the capital city of Bangkok, and Chiang Mai International Airport (CNX) in the northern part of the country.
  • The northern part of Thailand is dominated by the provinces of Chiang Mai and Chiang Rai, both of which are within reach of Chiang Mai Airport. However, only flights from San Francisco Airport (SFO) use this hub, so if you arrive at either of the Bangkok Airports, you’ll have to arrange a connecting flight to either Chiang Mai or Chiang Rai Airport (CEI) to get there.
  • The Isan Region represents the eastern part of Thailand and there are four major cities there, including Khon Kaen, Nakhon Ratchasima and Udon Thani. Suvarnabhumi Airport is close to Nakhon Ratchasima, but the other cities are at least a 5h drive away, so flying into Udon Thani International Airport (UDD) will definitely save travel time that can be used to discover the region.
  • The popular resort island of Phuket and its world-class beaches lies almost 500 mi from Bangkok, but despite the distance, it’s cheaper to fly into Bangkok and get a connecting flight to Phuket International Airport (HKT) than to fly directly to Phuket. Therefore, you may wish to factor that into your travel plans when booking your flight from the US to Thailand.
  • Families traveling on holiday to Bangkok will want to check out KidZania, a miniature city tailormade for children to enjoy. KidZania is less than a 30m drive from Suvarnabhumi Airport to Siam Paragon downtown.
  • Due to its proximity to Bangkok, the capital city of Thailand, Suvarnabhumi Airport (BKK) is a popular destination airport for most passengers flying from Los Angeles International Airport (LAX) to Thailand. Indirect flights with a single layover at Tokyo International Airport (HND) on carriers like ANA and THAI are an option for passengers flying this route.
  • Travelers who come hail from the east coast region of the United States prefer to fly to Thailand from John F. Kennedy International Airport (JFK) to Phuket International Airport (HKT). When using this flight route, passengers can take indirect flights with a single layover at Dubai International Airport (DBX) on airlines like Emirates and Qatar Airways.
  • Travelers from the central United States that intend to fly to Thailand typically use Dallas Fort Worth International Airport (DFW ) as their departure airport. Many indirect flights with a single layover at Heathrow Airport (LHR) on different airlines, including British Airways and THAI, are accessible from this airport to Suvarnabhumi Airport.
  • If you're flying to one of the northern cities in Thailand, the Chiang Mai International Airport (CNX), which serves Chiang Mai Province, might be a better airport option. John F. Kennedy International Airport offers two-stop flights with stopovers at Heathrow and Suvarnabhumi Airports, on a variety of airlines to CNX, with Virgin Atlantic and Bangkok Airways being the most popular.
  • Take one of the indirect flights with a single layover at Heathrow Airport offered by EVA Air, China Airlines, or JAL from Seattle Tacoma International Airport (SEA) to Suvarnabhumi Airport (BKK) if you plan to fly to Thailand from the northwest of the United States.

I put the review all together for the first review

I liked that they gave us a couple of meals and drinks but the meal was not good and not many options especially if we are seated in the back of the plane.

Again on this leg the WiFi wouldn't work. The seats were comfortable with adequate cushion and space between seats for my legs. Very nice 3-hour flight.

Everything was great, however the seats in the back are very small. Not as Comfortable as I would have liked.

Excellent food. Good service. Crammed Premium Economy seats. I Asked to change seats during check in. They told me the flight was fully booked. But on board I saw empty seats where I could have been easily relocated.

Good. Please add a non- applicable category to your questions.

Amazing crew, excellent food, business class seats seem a bit dated but are super comfy even for a very tall person. If continuing onto Taipei, the stopover in Bangkok is a bit annoying (queue at security) though the lounge is decent.

Boarding is fast and easy for economy class, food was ok baggage policies are good

Everything was fantastic! It was a short flight but the crew really went above and beyond to make it a great flight. I felt cared for with EVA.

Delayed due to no fault of flight crew. Efficient and worked well together.

Delta always provides stellar service. I am always impressed and will try my best to travel via Delta if I can afford it.

Everything was pretty good. I would like to have more drinks (water) during four hours of the flight.

This flight was the flight we missed due to deltas delay at our first airport going TO Atlanta.

Wi-fi was out for the whole flight. I pay a premium to fly Delta because it has wifi and because it was out I didn’t get to work on anything I wanted to. I’ll have to make it up later this week by spending less time with my family.

I enjoyed the whole flight and the crew was amazing i dont usually fly delta

Very nice the whole crew was amazing and very professional. I had an offer for a drink it was handled great and amazing crew and nice flight.

I just wish the boarding process/time to take off after boarding was quicker and more efficient. I also wish that the overhead luggage was managed better. almost every time i fly there is no space for carry ons and they are either checked or I end up having to store it several rows back from my seat. Delta should not offer carryons for all customers if there is not actually space for everyone

Boarding was delayed by an hour and then we proceeded to sit on the tarmac for another 30-40 minutes. No clear explanation was ever given and the delay caused me to miss my connecting flight home. Was forced to stay the night in the connecting city which impacted my following workday and cause personal issues at home as well.

I didn't like like much about my experience with Delta. I had to spend the entire day at the airport due to some mechanical issues. My flight was supposed to leave at 8:30am didn't leave until 6pm. Horrible experience.

Bad. Flight was delayed due to maintenance issue with Delta. Seats were small, no service, bag got broken on initial flight. Cramped and hot. Sitting inside with no ac.

Great flight. I should have figured out the bed situation in biz class earlier. Confusing in dark. My bad.

Business class check-in was flawless; was automatically given a lounge voucher. Flight attendants were helpful and professional. There was a purser who introduced herself at the beginning of the flight but then I never saw her again.

Weather delayed arriving flight and even though I made the connection, my luggage did not.

The service was better on this flight from the long haul one, but still very poor from The Cathay Pacific of the past.

Seat was very old. Didn’t easily go up and down. Flight Attendent had issues moving the seat. Condition of the seat was ok. Parts were peeling off by the foot area. Food was ok. Ran out of the dish I wanted so got the beef. Beef filet was very tender but the sauce was a little strange. Disembarking was very easy.

My connecting flight was canceled or never existed. My stopover went from 1 hour and a half to 10 hours. It was a long day that I wasn't prepared for and it would have been nice to know that ahead of time. Cathay is great though. Great staff, entertainment and food.

Baggage delayed for 2 days and still chasing for reimbursement of basis items. Very horrible customer care service.

Crew experience was more transnational, seats were so close together (LtoR and FtoB) that it was difficult to enjoy much of anything. When the person in front leaned back, there is no space for me. Sadly it was a flight to be endured not experienced.

One of the worst flight in business class by qatar airways and I’m no stranger with qatar airways businesses class, I travelled with the extensively in the past 12 years

Everything was good food could be better but ok for economy on my 2nd flight the head ph jack are bad you have to hold pushed in to hear anything but other then that very nice service

The first segment from Atlanta to Abu Dhabi was fantastic, but we got downgraded to a different aircraft from Abu Dhabi to Delhi. We were supposed to be on a flatbed business class when we booked it but just about one week before travel, we were changed to A321 Neo, which just has old-fashioned business class seats that recline but don’t go flat. While I fully understand that sometimes these changes have to be made for operational reasons, but I asked for some credit or compensation for that and I did not get any anywhere with that

Luggage jandling sucks. I arrived in BLR india on 15th and luggage was delivered today 19th. I came for a business trip everything got screwed up. Poor communication. APP kept saying mishandles in BLR. It never reached BLR. I had air tag which showed luggage was in Germany. I could not reach anybody other than the airpprt people. They had no clue and asked me to call etihad. In India etihad number wasnt working.i had to call US number and that person was the only person who seemed to help. They kept me in dark. No communication or email till i spoke to the person in US.i have flown many airlines but never had this experience. For me this was first and will be last in etihad. Very bad.

Awful , hidden charges for the luggage was a very awful thing, very much a scam , booking the flight thinking the luggage was included was definitely a scam , then the girl that was taking my luggage Ayrlease the airport was an absolute awful , telling me if I don’t have money to take my luggage with me I can just throw it away , how professional, NEVER AGAIN .

Connection booked by Etihad was delayed and upon arrival to counter they closed it and denied boarding although there was still 15 minutes to go . Manager Karen was very rude and did not want to listen seems there as overbooking and canceling boarding was the only solution..

Doubled charged me for luggage and lost $520, dug much into my travel budget.

We have paid premium price for a business class Cabinet and we have received the old 777 with the following apart business class that is not to standard. It was very disappointing and it’s a very bad reputation for a premium airline company. This aeroplane should be the commission from being as a business class. We will pass this knowledge to our colleagues because the quality of business class in Etihad is not consistent and it is a lucky dip that sometimes you’re getting a good aeroplane and sometimes you’re getting their 30 years old aeroplane. The crew of the aeroplane have apologise and said that they hate this aeroplane and they have complained about it multiple times as well. Obviously Etihad is putting the economy in front of the Customer Experience. For the future we will not take this risk anymore and will fly with established company like emirates.

I paid 44 $ for seat upgrade (22D) and my seat was stack in high position for all the 6 hours of flight. I don't recommend the upgrade. I am looking to get my upgrade payment back

Same problem place in the middle so small Im 1,85 m so not good 👍

I am a larger than average person and in my opinion i don't think it's fair to allocate a window seat to anyone who is my size or larger, i was seated between 2 large passengers on a full aircraft. The guy in the window seat also occupied a portion of the middle seat (my seat) which made my experience of flying with etihad very cramped and uncomfortable, i was flying from Abu Dhabi to Bangkok. Had this been a airbus 380 it would have been better as the seats are larger but unfortunately it wasn't so i had to endure the 6+hrs unable to get any rest

The staff was very nice and polite but it was very very hot and no ways to have some fresh air. It would be nice to have more time to sleep since it was a night flight

I need to note that this flight experience was generally fine but the boarding situation was absolutely a mess and there wasn’t any actual priority boarding. I rated the experience poorly because I’m am genuinely so frustrated with the crew on United taking the baggage space in first class. This flight it didn’t happen, but the last few flights (when I ironically don’t get an opportunity to provide feedback) have been spoiled because upon entering the first class cabin as one of the first few seated passengers, the overhead bins are full and ‘crew’’ tags are on the bags of those taking space. I don’t intend to infer some sort of a class or caste system but it’s absolutely ridiculous that the crew takes the overhead storage above and beyond their most loyal and lucrative customers. They should not even have economy space IMO. And I’ve gotten grief when I’ve noted to the crew the ridiculousness of the notion that the crew (who are the last off the plane) should have priority over flyers who pay. I hope you find a way to convey this message to United because it’s happening with increasing frequency and I intend to find a way to expose the specific crew members who are doing this on a flight by flight basis. (And I have a day job)

Great flight and crew. Need more legroom and DO NOT allow seats to recline.

Flight and crew were great. Need more legroom and do not allow seats to recline.

Bathrooms broken, Wifi not working, Direct TV stuck in a United credit card loop for whole flight

We arrived to Chicago nearly 30 minutes early, which was great, but then was on the ground for over an hour because the gate was not available. The issue I had was the pilot estimation was frustrating. First he said he was informed it would be 20 minutes but he said "it will probably be more like 10 minutes". After 30 minutes he came back on the comm and said it would be another 10 minutes, maybe 20. I understand he was only giving estimates but he also layered in his own gut feel. We were never told why we didn't have a gate even after our scheduled entry.

Just sat on the run way after we arrived early

New Max 10, first class seats have been shrunk. End of a 20 hour journey, it was United not Lufthansa, just glad to get home

I absolutely loved it. ANA has got to be the best airline. At least the best I’ve experienced. The food was good, even in the economy class. The staff very friendly and helpful. The cleanliness was always on point even at the end of the flight. It also seemed like there was much more space than the previous United flight I was on

Staff members were not helpful they ignored all calls for an attendant.

Is ANA airlines not united airlines, ANA airlines crew working professionally , more services providing, happy face to service customer
