FAQs - booking Thailand flights

  • Do you need a tourist visa to visit Thailand coming from Boston?

    No, tourist visas are not required for U.S. citizens traveling to Thailand. The only restrictions are that travelers cannot stay in the country for over 30 days and they must present a valid passport, with an empty page for a customs stamp, that can’t expire within six months of their entry date.

  • Are there direct flights from Boston to Thailand?

    No, unfortunately, there aren’t any non-stop flights to Thailand from Boston at this time. However, there are various options from Boston Logan International Airport (BOS) to the two main airports in Thailand with just one layover. The flights are to both Suvarnabhumi Airport (BKK) in Bangkok and Phuket International Airport (HKT), with layovers in cities like Doha and Frankfurt, operated by Qatar Airways and Lufthansa.

  • Which is the best airport to fly into to visit Railay Beach?

    Railay Beach is probably Thailand’s most visited attraction. To see this remote beach, the closest airport to fly into is Phuket International Airport (HKT). The secluded beach is only accessible by boat. Nonetheless, you can reach it departing out of the docks in Phuket.

  • How to do get from the main airport to the city?

    When you arrive at Suvarnabhumi Airport (BKK) in Bangkok, the capital of Thailand, there are various public transportation options to get you where you need to go. The fastest and cheapest way of getting to the city center from the airport is probably taking the Airport Rail Link. It takes passengers to the Phaya Thai district in central Bangkok in about half an hour, and you can expect to pay only about THB 45 (USD 1.50) for the ride.

  • How does KAYAK find such low prices on flights from Boston to Thailand?

  • What is the Hacker Fare option on flights from Boston 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 Boston 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 Boston 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 Boston to Thailand up to 3 days before/after your preferred dates. You can then pick the flights that suit you best.

Top tips for finding cheap flights to Thailand

  • The main airport to fly into in Thailand is Suvarnabhumi Airport (BKK) in Bangkok, the capital city. This airport is closest to some of the country’s top sites like The Grand Palace, the Wat Arun Ratchawararam temple and the Temple of the Emerald Buddha.
  • If you’re traveling with a pet or service animal on the long flights from Boston to Thailand, you’ll find multiple pet relief areas at Boston Logan International Airport (BOS). Here, your four-legged friend can relax and do his necessities before boarding.
  • For those looking to explore the northern region of Thailand, it may be more convenient to arrive in an airport of a neighboring country. For instance, Wattay International Airport (VTE) in Vientiane, Laos, is right near the northern border with Thailand.
  • When visiting Thailand from Boston, you’ll want to exchange some USD into the local currency known as the Thai baht (THB). This can be done beforehand by requesting foreign currency at your bank in Boston, or at exchange desks at the arrival airports in Thailand.
  • For those traveling with children from Boston to Thailand, Boston Logan International Airport (BOS) offers a few facilities that can help them blow off steam before the long flight. In terminals A, B and C, there are “kidport” playgrounds for them to enjoy while their parents relax.

AAAAHHHH... It was shocking in a very positive way, the attention to detail, the courtesy, the manners of all personnel on board, the constant honest smiling. You can see and feel they take pride in all they do no matter how trivial. The plane in general was very comfortable. I can't wait to do it again

AAAAHHHH... It was shocking in a very positive way, the attention to detail, the courtesy, the manners of all personnel on board, the constant honest smiling. You can see and feel they take pride in all they do no matter how trivial. The plane in general was very comfortable. I can't wait to do it again

Lousy entertainment system. Crews are excellent. Meal is just mediocre.

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

The flight was operated by Latam. The aircraft had a technical issue and the flight was delayed for the next day. They grounded other passengers to get their airplane assigned to my flight. Most of he ground staff don't speak English (Orlando Airport), but were very polite.The crew on the other hand could speak English and Portuguese. On board service was good.

The agent at check in and at the gate were less than thrilled to be at work. I'm not a fan of Kayak's placement on the plane. I got put in the middle seat and none of my preferences were used.

In ATL they have two sets of departure screens. Follow what is on your airline's departure board - the ATL Airport Authority departure board had completely incorrect details about the gate assignment for my flight, which would have made me miss boarding.

Flight was delayed it was hot while sitting on the plane, one engine was working on the plane until they had to do some jimmy rigging down the runway in order for the other engine to charge up. It was ridiculous

The flight was very good and the staff was very friendly and helpful!

The only thing I would say is we tried to get on a standby earlier flight, but with our fair we couldn’t. That seems senseless to leave with open seats..

Very easy to use and convenient, you can perform any action within the same portal

In a world of delays, Delta was on time both ways! Boarding was fast and efficient. Staff was friendly. AND wifi worked.

WiFi didn’t work. Flight delayed 3 hours Crew members were illiterate Seat lean back did not work.

Flight was delayed, we could have been notified earlier and in a consistent manner. App was not refreshing for another passenger to get the latest flight status. We could have stayed and waited at the hotel instead of waiting at the airport had we known the flight was going to delayed for more than 5 hours. The toilet is too tight, and needs to be cleaned more frequently (every hour). The entertainment screen froze, the touch screen not responding to touch. We were upgraded to comfort, it is more comfortable than regular economy seats.

The crew and the food were excellent. The plane was kept quite clean.

Crew were not engaging. Only engaged if requested. Food taste was mediocre

I booked wheel chair for my mother but she was told to walk by herself in the middle of her way to the gate. She had to board a connecting flight under a time crunch and this was unfair to leave her to walk. Other than that they had no complains about anything else.

The flight attendants were very helpful, efficient and courteous in helping everyone!

My seat had many issues. First the chair was broken where reclining was difficult. My usb plug was also broken so charging was impossible.

The flight from Hong Kong to Hyderabad didn’t have any power points to charge my mobile. Given we are no longer allowed to use power banks, giving customers the ability to charge even on short flights is critical part of the overall experience.

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.

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.

After each meal was served I didn't see any flight attendant offer coffee or tea to the passengers after the initial drinks were offered. Other flights I had been one it was standard procedure to offer hot drinks after the meal service.

Extremely uncomfortable seats with very little cushioning, unable to recline enough to sleep comfortably on this 13 hour overnight flight. My body was in pain by the end.

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.

I booked tickets for a family of five and specifically paid extra to select our seats together. We spent nearly $1,000 extra (around $100 per seat) for extra legroom so we could sit near each other. However, despite paying for this, we ended up being separated on the flight. This caused a major issue for our family because my parents do not speak English and rely on me to translate and assist them during the journey. I do not understand why Etihad changed our reserved seats without explanation. I am extremely dissatisfied with this experience. I expect the airline to do better, and I am requesting a full refund for the seat selection fees we paid.

Dear Team, I purchased a full travel package that included 2 checked bags through you and JustFly. However, when I arrived at the airport, my ticket showed 0 checked bags. Since I was traveling internationally to India with 2 bags, It was a $200 per bag at the counter, which was extremely disappointing. For an international trip, why would I ever choose a no‑bag option for only $20–$30 less? This seems like an error in the booking process, and I am requesting clarification and a resolution. I have called JustFly and on phone for 1 hr :53 min and they couldn't help till I show some kind of proof etc which isn't possible but besides that love your service and using it for years !

I liked the crew, the food and the foot space. I did not like the comfort of the seats.

Good one but just notice that you have to ask several time to get water or coffee .

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.

There was not any issues with the Etihad Airways. Staff was excellent and I love the variety of movies and games that they provided.

It was fantastic. The flight from Chicago to Abu Dahbi was fantastic. The crew, food and service were amazing. Everything was handled by the crew member assigned to us , Nicholas, was usually done before we asked for it. Highly recommend Etihad!

Etihad Check In counter/Station manager in Heathrow was bothering and not helpful at all. They are rude and not customer oriented

I missed my flight ,staff unhelpful, they sat and watched me wait ,gangway door closed, English was a problem no announcement I was on time now I missed my month vacation ,lost 1400 bucks no refund I'm sick to my stomach

It’s a business class ticket but they didn’t give a lounge access
