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?

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 $581
  • 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.

Their was $200 charge for 2nd luggage, airplane very new and flight smooth. Flight time seem faster then Asian stoping Korea then china.

Flight was late boarding. United crew were not friendly and cordial unlike the ANA crew.

Seat was broken. Check in was not possible until we reached the gate, by then we were separated.

The food was not great; but I don’t expect much from airline food. However, the staff was incredible! I had gotten to the gate when I realized I had left my computer at the security checkpoint! I told a staff member and she said, “well, you will miss this flight if you go back to get it” It was a long way from the gate. I asked if I might get on the next flight. She sent for another staff member, and he took me to the gate desk. He found an open seat, and said,”okay, go run to get your computer, I will get you a new boarding pass.” I rran back, retrieved my computer, and returned to the gate. It was closed, but I found the gate nearby where the next ANA flight was leaving. Another staff member was ready for me, and printed me a new pass, and even made sure I still had an aisle seat that I requested! I got in line and continued my trip. These people are amazing, helpful, and friendly. My trip could have been ruined, or postponed at a great expense, but they saved the day! 5 stars!!!!

I originally thought I was booking with ANA airlines and didn't see "operated by United" until the day of. I even thought the United check-in update was a scam so ended up checking in 3 hours before the flight, causing separate seating and uncomfortable middle seats.

Very disappointing. Our flight was delayed for almost 6 hours with the lost time disrupting our travel plans. United should have known that any delay (approximately and hour) triggered a no-fly/work because according to the FAA they had to many flight hours. After the mechanical delay (approximately an hour) we had to wait for a fresh crew change. Seems to me that United could have anticipated this incident. Again, a very disappointing travel experience.

Excellent crew, food and comfort from LA to Narita. Flight from Narita to Manila was just okay, Food and comfort needs to improve. The business class was not comfortable.

Lots of leg room in premium. Departed exactly on time. Friendly crew.

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.

I’d have rated Asiana good except an unfortunate incident in which I felt one of your employee didn’t really help us. During the first leg of the trip, the flight from LAX to ICN, I left my backpack on the plane. When I realized, I reported to one of your employee who promised me that it’d be taken care of, that my backpack will be there at HCM city. When we arrived there, HCM people had no idea and my backpack was still at Incheon airport who denied any knowledge whatsoever. I was left in the cold and felt helpless. I was very disappointed. I’d like someone to look into this and let me know.

It was my first time flying Asiana but i was very pleased with how professional and understanding the flight crew is with little kids. One flight attendant held my 3 year old daughter’s hand guiding her to the exit after landing while i had my hands full with luggage and my infant. She was very helpful.

Better screens, it would have been nice to have more comfortable seats.

2nd major delay due to maintenance issues. 1st delay missed my connecting flight.

Very clean ,flight attendants very professional,nice , Boarding was very easy

The aircraft was massive (A-380) and became crowded with 400+ passengers on board.

The plane hasnt left im stuck in seatle still my flight has been grounded for almost 5 hours

My luggage didn’t arrive with my flight. Flight was delayed by nearly 2 hours while we sat on the plane and I almost missed my connecting flight and subsequently missed the last train from the airport so it took me another 2 hours to get to my destination after arriving, Crew skipped me several times when offering beverages, and I couldn’t get their attention at times because they wouldn’t even make eye contact with me. They didn’t give me a form for disembarking so I had to go to the back of the line after waiting an eternity for immigration. Paid for on flight wi- fi that didn’t work for most of the flight.

Love flying Asiana. Been using it for over a decade now.

Coming back to America was a peaceful flight everyone and everything was perfect

when i ask for help all the crew members had a look like why are you calling me? very terse and rude.

Good service and food. However, we paid over $400 for aisle seats for my disabled husband and me, and we were given window and middle seats. This was dangerous for our health condition on such a long flight. We needed to stand up and walk around frequently, but we were stuck in our seats. Please give us a refund of our seat payment since you chose not to honor our request.

Poor links to cathay meaning it's not possible to check in online or reserve seats. Incorrect information provided by cathay regarding check in and transfer at HKG. Delay in flight required is to be escorted / run to make the connecting flight and no opportunity to use the business lounge. Luggage did not make the connection so we arrived in Manchester with no luggage

Very bad Instead 22 hour it take me more that 35 hour to arrive from Los Angeles to Phuket and they changed my flight in Hong Kong to Shanghai china and in order to get my bag I was forced to vet china visa entrry

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

We flew economy light. We did not want to check bags and we had free 1 bag, but just had back packs with small personal item. Try as we may could only get bags down to 17lbs each. So we put 2 lbs from one bag into other and checked it. I think if someone has a checked bag allowance and chose not to use it , it would benefit both parties to bump carry on weight up to the next level of 22lbs or 10kgs. Just a thought.

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

ticket agent lady wás very helpful , she arranged wheel chair for my elderly mother

Didn't make the flight because the first leg of my flight was canceled and the next leg was already booked.

My flight was canceled a few hours before boarding. I was rebooked on Copa airlines and missed an important meeting .

Good quick flight on a small but comfortable plane. I'm 6'3 and had plenty of space.

Experience was great - no complaints. Took off on time, landed early. Got to the gate relatively quickly - took a little bit of extra time to deplane but nothing excessive.

Business class seats felt very cramped compared to other airlines.

Economy plus was so cramped I could not use my laptop. It was beyond bad.

OK, we were delayed and had to de plane and reboard.

United is one airline which regardless of how many separate United tickets in existence, if one flight breaks down, the airline will take care of all the flights.

Both our flights were delayed. Almost didn’t get in the second flight. Staff was rude to the bone.
