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.

On time and no hassle luggage policy (2 checked in and 1 cabin bag)

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.

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

I paid 44 $ for seat upgrade (22D) and my seat was stack in high position for all the 6 hours of flight. I don't recommend the upgrade. I am looking to get my upgrade payment back

We booked a business class ticket via Underpricer. Somehow they screwed up our ticket from Abu Dhabi to Ahmedabad. We will be hesitant to book again with them.

Same problem place in the middle so small Im 1,85 m so not good 👍

I am a larger than average person and in my opinion i don't think it's fair to allocate a window seat to anyone who is my size or larger, i was seated between 2 large passengers on a full aircraft. The guy in the window seat also occupied a portion of the middle seat (my seat) which made my experience of flying with etihad very cramped and uncomfortable, i was flying from Abu Dhabi to Bangkok. Had this been a airbus 380 it would have been better as the seats are larger but unfortunately it wasn't so i had to endure the 6+hrs unable to get any rest

Good. The food was very bad. Except for the chicken rice, rest of the dish went to trash.

The staff was very nice and polite but it was very very hot and no ways to have some fresh air. It would be nice to have more time to sleep since it was a night flight
