FAQs - booking Thailand flights

  • 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.

  • How does KAYAK find such low prices on flights from the United States to Thailand?

    KAYAK is a travel search engine. That means we look across the web to find the best prices we can find for our users. With over 2 billion flight queries processed yearly, we are able to display a variety of prices and options on flights from the United States to Thailand.

  • How does KAYAK's flight Price Forecast tool help me choose the right time to buy my flight ticket from the United States to Thailand?

    KAYAK’s flight Price Forecast tool uses historical data to determine whether the price for a flight from the United States to Thailand is likely to change within 7 days, so travelers know whether to wait or book now.

  • What is the Hacker Fare option on flights from the United States to Thailand?

    Hacker Fares allow you to combine one-way tickets in order to save you money over a traditional round-trip ticket. You could then fly from the United States to Thailand with an airline and back with another airline.

  • What is KAYAK's "flexible dates" feature and why should I care when looking for a flight from the United States to Thailand?

    Sometimes travel dates aren't set in stone. If your preferred travel dates have some wiggle room, flexible dates will show you all the options when flying from the United States to Thailand up to 3 days before/after your preferred dates. You can then pick the flights that suit you best.

  • What is the cheapest day to fly to Thailand?

    Based on KAYAK data, the cheapest day to fly to Thailand is Thursday where round-trip tickets can be as cheap as $314. On the other hand, the most expensive day to fly is Sunday, where round-trip prices are $441 on average.

Top tips for finding cheap flights to Thailand

  • Looking for cheap airfare to Thailand? 25% of our users found round-trip tickets to Thailand for the following prices or less: From Los Angeles $956
  • Enter your preferred departure airport and travel dates into the search form above to unlock the latest Thailand flight deals.
  • 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.

The boarding process was efficient and quick. The seats were comfortable. The food was good. The service was excellent. We had a lovely flight from Seattle on Korean air

Flight crew was fantastic. The aircraft was meticulously cleaned at all times. The crew was continuously checking to see if the passengers were ok.

They were trying to get people to check luggage because the over head compartments were full but when we boarded there were lots of empty places that people could have put the luggage.

It was good, I liked the self-serve snacks but it was a little difficult to get the alcohol, which is understandable since I wouldn't want kids sneaking it.

Friendly flight attendants and gate agents. Very clean plane and food was good!

I was unable to select decent seats, and so I was stuck in the middle seat because it was selected for me

There was a lot of partial tv shows but not enough to last the flight. The food was incredible! The crew were so helpful and patient. Lots more space than what I usually get on an international flight. Very comfortable!

Stingy on the drinks - 15 hour direct flight and could barely get attention for some water

Not many people, so you can lay down on two seats

They did an excellent job helping me with a wheelchair. I couldn’t have asked for any better help.

Cabin Crew was excellent. They took care of everything requested. Flight was good

I was charged $200 for a 2nd checked bag, which is unreasonably high and feels like price gouging. Other than that the experience was excellent.

The ROOM was great. We would love to have it on all of our flights. LOL

I would prefer to fly with Japanese airlines over American ones. They have better food and service overall

Service is great. Seat is ok. Not much storage room and seat is hard but seat topper was nice. Cabin was very warm most of the flight. Washoku Food was good.

United Airlines crew members do not know how to deal with emergency situation that caused our flight delay. For example, they should have asked the maintenance or seat belt repair personnel to come and fix the seat belt while they were looking for a volunteer to book another flight.

The pilot was kept warning about the weather terrifying us. The flight attendants were not warm or pleasant.

Entertainment and food is best. I love to use ana for a lots japanese movies…. Food was best

I couldn’t sit with my daughter. we are separate and both seat was not window or halway side. in the middle. if we sit together will be share comfort seat and more easy travel. this is bad.

First trip from Tulsa to Houston by air. It went by quickly. I watched half a movie and continued the rest on the next flight. Staff was considerate and helpful.

There could have been more options on the entertainment section Nothing was available for non English speaking passengers

I was mid plane and they were already out of the main beef entree....ugh!

I didn't have much experience with Cathay Pacific airlines because of delay and missed connections, the bulk of the trip was on Japan Airlines.

Flight delayed first from bad weather, then after boarding there was a problem with the plane. We had to get off and onto another plane...connections were missed and the trip took an additional 10 hours!! Pre-paid seatting was not honored due ro last minute carrier changes. Most of the trip was on Japan Airline.

Crew and food were great in-flight. We had a 2 hour delay, no communication, and just got left in a limbo. The crew arrived late and they were running checkouts on the plane (which is important, but why not doing it earlier?) Cathay did nothing to about the delay, and a lot of people missed their connection flights. I had to run and got stuck at checkpoint, which made my entire trip very unpleasant. Got to my gate 5 mins prior to them closing it.

My flight was suppose to be at 7:45pm to fly but it didnt fly out until 8:55 to dallas so then all of my other flights was late and delay ihad to wait at the airport for extra 14 hours to be able to get on a different plane

The flight was just ok, but the vendor made it exceptio ally bard to manage my own reservation and would not give me access. The blocked all of the one time pins to come to their email address which caused me.to go through them eceryrime to get seats see rhe reservation and even get wheelchair access for my sick 71 year old uncle. They only xommunicates via a bot which gave me incorrect info. I thought this was Kayak and not underprivileged. They ruined his trip, did not get him aisle seats and made it impossible to purchase extra leg room. It was a horrible experience. He was taken to hospital on arrival only to find he had blood clots and pnemonia while trying to navigate the airport. This vendor is very irresponsible and the airline could not access his info.

There were delays at boarding and landing. These events resulted in a tight transfer time in HK. Poor signage for transfers. Finally, lost luggage at final destination.

It was good. The planes needed to be updated though, they were dated and the entertainment systems were old. Service was amazing. The pre-booked meals were lacklustre.

Super delayed. Unnecessary. Need more competent people doing logistics to keep things moving on time. Totally unacceptable.

When we checked in at the Siem Reap Airport in Cambodia, we were only given three boarding passes and told that we would have to check in with American when we arrived in Boston. This was a source of stress for us. After we landed in Boston, we had a long passage from Terminal E to Terminal B (American Airline ticketing counter). Because the electronic ticketing kiosks for check-in would not recognize our Confirmation Code, we had to wait for an hour in a long line where only two AA reps were taking care of Special Services passengers. In many years of both business and recreational travel, I have never had this experience. I would expect more from AA being in partnership with other airlines to do a better job with this.

This flight was a very good trip for us. The crew were very friendly and helpful. They made arrangements for my husband to have assistance in boarding. We were not expecting a meal, so it was a pleasant surprise on this short flight to have a meal and beverage from a very courteous crew.

Our experience on the Doha to Hyderabad segment was extremely stressful due to prolonged delays and a lack of clear communication from the airline. We were traveling as a family, including children, and the uncertainty around timing and next steps caused significant distress. There was very little proactive information provided during the delay, and we were not given clear written explanations about what was happening or how long it might take. This made it difficult to manage the situation, especially while caring for children in a transit environment. In addition, one member of our party was ultimately unable to continue travel, which added to the emotional strain and disruption of the trip. Overall, the experience highlighted gaps in communication, customer care, and handling of unexpected situations. We are sharing this feedback so that future passengers, especially families, are supported with clearer communication and better assistance during irregular operations.

The seat cushions are absolutely lacking, not sure if they know the passengers are traveling for 14 hours straight, but the padding made our back and butt ache like crazy. The entertainment console had its own problems, either the headphone jack wasn't working or the power outlet via usb or ac outlet was not working. Not to mention the seat handles were not adjustable in some planes in the middle or on the aisle. Qatar/Indigo may be operating a very old fleet of planes to make as much profit as possible, but passengers may not be following them for long, should this treatment of its customers continue. Qatar/Indigo, wake up and do it right by your customers, or they may not be your customers anymore.

It would help id flight crew were not rude and showed some courtesy. They were shouting at passengers and yelling instructions as if we were school children at lunch cafeteria!!

All good. Over four hours flight if provided snacks like Qatar Airways would be better

Lobster starter in business class was not good, tough, served cold, and without butter. Movie selection was missing latest releases, did not offer older classic, high quality movies

Food was absolutely pathetic. I wasted so much food which I thought was inedible. I also loathe the inflight entertainment system which has very little content

My entire row did not have power for the full duration of a 14.5 hour flight. Could not charge any devices such as laptop or phones for the entirety of the long flight. The flight attendants tried to remedy the issue by resetting the power, but were not successful. The only other solution provided was to move me to another seat on the plane which was in the middle row. I had paid for a “preferred” seat that was a window seat. This was a downgrade being offered due to the power issue.

Nothing to complain. The staff and flight was good especially the seats which was better compared than the cloth ones on Qatar airways

Not being stranded in Chicago for her airport to 11:30 tomorrow morning the 3rd

the whole trip was smooth, and as comfortable as flying is these days. flight crew was friendly and very courteous and helpful.

The attendant on board was amazing. She should be doing business/first international long haul.

Although our flight was delayed the overall boarding process was very smooth and the crew was accommodating.

I was fully checked in the prior night and i was unchecked and then didn’t have a seat when I boarded. Instead of an aisle seat, I was out in the middle seat of the very last row of the plane.

In overall it was a good experience, the only down point was that the entertainment screen was working properly.

HORRIBLE, my initial flight was cancelled, they made me pay $200 extra dollars and that got cancelled as well! After 6 cancellations I decided to get a refund because I needed to get home to my babies. Out of $1000+ dollars they offered me only $40 in refund! Totally unacceptable! The flight that they cancelled I was able to fly it on another airline. I had to spend $400 on one way tickets just to get home! I’m still getting the runaround.

First class ticket gets you a choice of chips or nuts. . Just like economy Southwest. Also no screen in the seats. This is first class???!

Seated dude next to me even though lots of empty rows. But main thing was we sat on the tarmac after landing for 30 minutes because of, in the words of the dude who sat next to me, “operational incompetence”. We got changing directions about where to pick up gate checked bags. Pilot and flight attendant were awesome though.

The food was terrible this time. Otherwise pleasant, quiet, on-time.
