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 $631. On the other hand, the most expensive day to fly is Monday, where round-trip prices are $874 on average.

Top tips for finding cheap flights to Thailand

  • 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.

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.

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.

The delay in Korea was a pain and set us back a day. I have to give big props to Korean Air for setting up a hotel with dinner and transportation to and from the hotel. I also needed assistance with a wheelchair and they did an outstanding job.

Great except for the delay in Korea. Korean Air did a great job setting up a hotel for the night. I also needed assistance with a wheelchair and they were outstanding.

Warm the bread. Movies: better choices to include Chinese movies options or some of the older winners of flim festival

Almost 6 hours of delay with over 12 gate changes. Flight was supposed to depart around 6 and instead depart after 12am. No accommodations were offered than some snacks closer to midnight when the crew was planning to throw away some snacks.

The crew was very nice and polite. They made sure everybody got their meal and drinks. Even the economy class had a very adequate leg room for someone that is over 6 foot tall.

Overall it was good. Making changes to the reservation on ANA’s website was little challenging. Would like to see those features improved in the future.

Purchased WiFi was slow to non functional. Staff was not personable or friendly. Seats were cramped. Boarding took long but I expected that.

Luckily I just tried to sleep. But the entertainment system was awkward to operate. I hate all this stuff with apps and adding it to your phone and all. It is a nuisance. I would prefer a good magazine or newspaper in the pocket in front of me or available.

The seats are uncomfortable. The flight attendants are not pleasant. They do their job, but not with a ray of sunshine and warmth. The food was awful, not what I would expect from an Asian airline. All of the other Asian airlines I have flown have far better food. The food was on par with United airlines food, which is really bad. Maybe ANA should get out of the alliance with United.

During booking, I selected the seats so that my wife and I would sit next to each other. However, the airline changed our seats at boarding so that we were seated apart. Very disappointing.

One of the best 14 hour flights I've ever had. Crew was friendly throughout which can be difficult on longer flights. The crew being kind and respectful is very important for me. Plane felt clean and I was able to get some well needed uninterrupted sleep. I put them slightly above Cathay Pacific as far as cleanliness the only down side was a lack of entertainment selections, but hey I am an American taking a trip on a Japanese airline so I cannot complain. Thank you ANA and the Tokyo airport all very friendly. Will see you soon

Poor. We weren’t able to check in online (for several hours until we gave up) for no apparent reasons although our passports were loaded successfully. When we were at the airport check-in, a rep helped us at the kiosk but she disregarded the KTN provided to her so we had to come back for it after being questioned by the TSA person…

I was only given 2 meals, and my screen showed that there were 3 meals. Second meal was 1-2 hours late according to the screen.

Paid a premium a have a shorter transit time in Hong Kong, but Cathay pacific rebooked me and ended up waiting for 10 hrs in Hong Hong airport.

As before, my only problem was not being able to download my boarding passes prior to arrival at the airport. Everything else was perfect.

If I had blood clots, that window seat would've killed me for certain.

They ran out of food and were offering random food to passengers.

Flight was delayed at the last minute for six hours. Instead of delaying it to a normal hour, they moved it to 10 pm to essentially make it a redeye. There was no compensation or benefit offered for this inconvenience. Once on the plane, Inpaid for WiFi twice with both times it not working because of a “weak WiFi signal”, according to the flight attendants. They also chose the farther possible gates in both airports from the entrance/exit, even though they were one of the few active flights left so late in the evening. Overall it was pretty horrible.

I've stomach problems after 2 hours of flight, Iris, the flight purser not only did her best to make me feel comfortable, she went above and beyond providing pain relievers medicines and ointment. She look and found a doctor passenger on the flight to provide advise. She even report on ground staffs about my condition and provide wheelchair upon arrival. Kudos to her and Cathay Pacific!

Worst experience I have ever had with any airline in over 25 years.

Everything was fine and I have no complaints or things to note.

The flight was delayed for 30 mins. The overall experience was good.

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

I prebooked a comfort plus seat on this flight and therefore the flight was comfy. I got the correct seat in the correct section of the plane that I have booked, that's this. Flight was comfortable. Staff were average on the flight, appearing to be rushed and short in engagement with travellers, perhaps this to maximise there rest time on the flight.

I was travelling 3.5 years after. Agree Economy is no business class but the food was mediocre. Ordered a Hindu meal, the salads were bitter . The food was really below quality and had no tast from what I had in the past. Indian Railways probably have a better quality food when compared. However the kids meal was really nice and really appreciate how they were taken care of. The restrooms were dirty .

My flight was with American Airlines 120. The flight was delayed 3 hours and I missed my connection. When I arrived in Doha, the AA staff told me to call an 800 number to rebook a different flight, which was unacceptable. Eventually a Qatar Air staff member helped rebook me on a flight to Manila, that was 12 hours later. They offered me a hotel and meal voucher which I declined, because I didn’t want to leave the airport. Long story short, I spent 12 hours in the Doha airport waiting for my next flight.

Overall the experience was neat with crew being nice and caring especially to parent with kids. The free snacks option was okay. The kiosk at Philly airport didn’t work.

Reason for travelling Tampa to Orlando is to fly Qatar Airline. we end up with American Airline. This was the miserable experience I ever had in my entire travel history. Flight attendants were rude. They hit my knee with the food cart and I was holding ice pack for 2 hours. I still have the pain after a week. WE boarded the flight twice because of the temperature inside the plan.

First keep the airline as you promise. Reason for travelling from Orlando to Tampa is to go with Qatar Airline. We end up with American Airline. As expected the service was horrible.

Not sure how we end up with American Airlines instead of Qatar Airways. From Philadelphia to Qatar they boarded us then they asked us to unload. After 30 minutes later they board us again. The inside the plane it was burning hot and we were sweating like crazy. Crew members are absolute rude. The way they served the passengers were horrible. One of the crew members hit my knee with food cart and kept going. I was holding an ice pack for almost 2 hours. I am still with the pain.

I felt that when I was rerouted it should have been to business class.

Terrible. They wouldn't allow me on my flight on the 14th..

We had to deboard 2 times due to maintenance issues. They changed the plane, and then we got deviated to LAX due to maibtenance issues on the other plane, had to sleep at LAX and los a full day.

Everything was good, except the seats in economy were so close together, you could barely get out when the seat in front of your was reclined. If the airlines keep jamming in more and more seats, it will become intolerable. I will look for another airline that considers customer comfort and does not keep adding more rows of seats for more profit.

The newer screen was super cool and had the option to watch many different shows or movies. Crew was polite and helpful. However again, many children screaming bloody murder and kicking my seat, and parents doing nothing about it as usual.

Flight was good and crew was super polite. However, there were around 5 kids screaming the WHOLE 2 hours. I understand kids have to come but parents need to do something to control their children. They make the experience terrible, especially after finishing 16 hour shifts at the hospital I needed some sleep, which I did not get.

IAD with the archaic people movers is just a place to be avoided.

Great service on board. Boarding a bit slow due to process. Food was pretty average.

Tastless food and too obvious lack of enthusiasm for service in the economy vesus business class

All of the United employees I interacted with were professional and courteous. The aircraft was clean, the food on the flight was good. No complaints here.

I had no checked baggage but was required to hand over carry on baggage at the door of the plane. There was a lot of overboard space in the plane and I was one of the last ones. I ran to get my carry on but it was gone. I was given back at the plane door in Toronto, so the wait was not as long as it would have been at the carousel.
