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 return 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.

i have book the flight with baggage. and i have paid $800.00 for the baggage. when i contacted to JUSTFLY Costumer Service they told me that my baggage was included in the booking. then why i have to pay. i am going to file a complain against it. $800.00 is not at all small amount

They lost the baggage and said it was deleted from the system. I had baggage tag so was able to file the complaint but there was no PIR number and update so far

Very disappointed to not have lounge access The shorter flight seats were uncomfortable

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.

The seats seemed smaller than other business class offerings. The entertainment menu was limited. Flight crew was good.

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 .

Kayak and Aran grant issuing business class tickets without lounge access and sometimes 1 or 2 connections in economy class. It’s very disappointing to find out that after buying the ticket. Never buy tickets on kayak and Aran grant again

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.
