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.

  • What is the Hacker Fare option on flights from Boston to Thailand?

  • What is KAYAK's "flexible dates" feature and why should I care when looking for a flight from Boston to Thailand?

The flight crews were extremely professional, helpful, and courteous. Departure and arrival times were accurate. No delay. I will use K airline again. Thanks

On time and flight crew are always so happy to help and always smiling unlike other airlines.

Great crew, decent food Charging plugs were broken on both seats next to me. Only the USB port was available, and that charges, very, very slowly. Seat was also broken, it would not lock into position when reclining.

Korean Air had great service and the Bibimbap dish was the best airplane food I’ve ever had. It was a long flight so in between the two meals they served customers could get Shin ramen. The flight attendants let my children use a pair of nice headphones for the flight and had earbuds and slippers for all the adults. The flight was long but the time passed by relatively quickly because they have many great shows in their entertainment TV. I watched the BTS Love Yourself and Speak Yourself concerts 💜

not too bad but not too great either. Service on all airlines declined ever since covid. Your Delta Stewardess are not that friendly at all. :-(

You did not put me on a Korean Air flight! so I do not have nothing to say

My flight was diverted to Atlanta and I was not given enough time. I paid my travel on April 23, 2023. It was originally Delta from Norfolk to NY, then Korean Air from NY all the way Philippines which is my final stop. Instead from Atlanta to Korea I flew Delta which is okay. Then Korea to Philippines, I flew Asiana Airlines. What I did not like, Ieagle did not sent me an email that my flight was change and so when I went to check in Wednesday the 10th, at 4:30 a.m they told me my flight was delayed at 6;00 p.m and diverted in Atlanta and I am flying Asiana from Korea to Philippines. I do not appreciate that Kayak or Ieagle chenge our flights 5 times and then last minute change again during my day of flight. I hope that you will not make any changes of my flight o Feb 15th because it has to be the same flight with my husband. That is the reason why we made the arrangements early on.

Wonderful cabin crew!!!!! Food was poor, in flight entertainment was just ok. They need to serve more water on a 15 hour flight--we were dehydrated and kept asking for water.

Going through security a third time to get on the next flight was again utterly ridiculous and unnecessary. We were in a International secure area once again and as far as I'm concerned should not have been put through the gears for absolutely no reason. The United States can get all the information they need from the travel itinerary, there was no need to be forced out of a secure area to personally interview everyone on a connecting flight to find out their US immigration status.

Flight arrived early, fantastic, since it is short flight, no food being served

Food as always. PA was not clear, especially the English ones. Very limited Hollywood movies. Unlike the first flight I had, this plane has less leg room and less room for my under seat baggage.

I like the braised beef., miso soup,, and green tea. Very little choices of hollywood movies. The PA announcement in English was not very clear and very soft. I could hardly hear.

Please change menu every now & then bc I fly twice within the year and serving the food the same

More updated movies & Chinese movies. The food sometimes overcooked. Prefer to have more neat snacks in between than just choose from the menu. Please change the menu every now and then. This is my second time flying within one year and the menu didn’t change at all!

Food is lagging. Very poor choice. Like vending machine fast food.

Please change the menu more often. The beef is not tender, more choice in ice cream flavor. Dessert is not good too.

The Experience was fantastic, it's a quick flight so no entertainment or food. Just a refreshment

Again I paid for an upgrade on my credit card didn’t get it need a refund. . American I not good at gettin in contact for refunds.

I didn’t like the check in process I had to check in at the counter took too much time . Didn’t give the upgrade my seat .

l enjoyed the variety of good and drink choices. The flight attendants were very quick and efficient to our needs.

Flight got canceled without any prior information and it caused lot of trouble

Staff were friendly, and provided great service. The food was plentiful and delicious. Food could have been hotter.

I was traveling business purposes and I only had one carry on and a personal computer back pack . My carry on was 8.5 kg little more than allowable. At jfk airport check in they did not let me carry it . I was little disappointed.

More leg room and comfortable seats at least for long flights

The entertainment selections are amazing. But the live TV is sometimes spotty. If you’re going to have it, then have it. If you can’t make it consistent, then, perhaps it’s better not to have it. The crew are always cordial when approached, but they seem to do the minimum and sit around, talking to each other in the back of the plane during the flight. I realize that delays are not always predictable, but I missed my flight in Dubai because we left 90 minutes late from Washington. I will say that Emirates took very good care of me in Dubai. But I would rather not be delayed.

Probably the best flight I’ve ever been on. Emirates first class is leagues beyond British airways and Lufthansa’s.

Great flight. Comfortable seats, courteous service, and excellent selection for entertainment.

Serving food took so long . Almost time close to lend. Plus during landing air pressure in cabin cuss ear blocked took long time to unblock.

Emirates is usually on time, but not this trip. Also, during the flight the attendants disappear unless called upon. Very strange. I have watched the quality of Emirates service diminish over the last five years.

Food was not great. Crew members were created hassle with attitude at the gates and wasted my valuable time. I have been traveling in Emirates airlines many times. Over all not happy flying in Emirates airlines this time. Seats are very small and not comfortable. Seats looks like very very old and congested. It would be nice if they fix these kind of issues. I hope my next trip will be hassle free and comfortable journey in Emirates airlines. Thank you.

Checking in at the airport the agent only booked the first keg of my trip and had my checked luggage going to the airport with a layover! Never was issued a boarding pass for the second leg or received sticker fir my checked bag. All was well in the end! Delta agents helped to resolve the situation!!!

Delayed due to an ill passenger after loading. Not preventable on Delta's part. Was in first class. The seats are becoming worn and detaching from their velcro attachments. Only got snacks on flight. The attendant was not the friendliest.

I would fly again the whole experience was great. The only feed back I can give that they don't do that American Airlines does is the crew there is more humorous with boarding and thank their passengers. It makes it more fun to fly with them. I would however fly Delta again.

Big plane, long flight, absolutely no leg room and basically non existent air! I am 5”4’ and always travel Main Cabin, I was miserable on this plane and could barely move when we arrived in Cabo due to the cramped leg area!

From Atlanta to Cabo I would have hoped on a plane that size I would have been able to breathe and wiggle my feet a little! The leg room in that plane is non existent and I am only 5”4’. And the air vent either wasn’t working very well or just could not blow air from the ceiling to the seat area as I was suffocating through the entire flight! And please don’t say I would have been more comfortable in first class because I cannot afford those rates and have always travelled Main Cabin without issues !

The pilots were good. Disappointing when planes don't have electrical ports

I liked the piloting of the aircraft. Very disappointed about lack of electrical ports. Also, although a short flight. there was enough time to hand out snacks to comfort + seats as was done for first class.

I had a wonderful experience flying with delta. The gentleman taking care of us on our flight was so nice, accommodating, and attentive. He always was smiling and giving pins to the kids which made me smile. The flight was quick too and without turbulence. Thank you for the great flying experience.

Delta is one of the best airlines I have flown

Made the Atlanta to Pittsburgh trip many times, with Delta no issues

Excellent service and comfort from the moment you check in. Flight crew is hyper focused on making passengers comfortable and at ease. It’s like a flying hotel!

Only chicken as a meat dish through out the flight

Nothing really was great as such. Seen other no name airlines perform better.

Quality of service on board was very inconsistent. FA service primarily seemed robotic and they barely engaged with passengers

I’m unclear why I had to pay extra for assigned seats as Turkish airlines did not honor the seating. We were placed across the aisle from each other on TK 34, and were seated behind one another on TK 694. Because my name was misspelled on e-ticket (Klawiter, instead of Klawitter) I could not log onto website to get the connection gate number in Istanbul. The monitors in the airport were a jumbled mess 1/2 Arabic and 1/2 English.

The airplane from IAD to Istanbul was too old. The chairs were to tight and uncomfortable. I continued my travel from Istanbul to Bangkok. This airplane was better and newer than the first one. Even food was better.

On line check in needs a lot of improvement. I tried and gave up.

They use a smaller international plane and quarters are tighter, space smaller, and the flight is still 12 hours, then fight attendants are ruff, food is bad, cherry juice spilled by flight attendant and she comes back to ask why have we not changed yet could it be we didn’t have any clothes to change into and seat is all wet and we had to sit there for 12 hours

Food not good, flight attendants not the best, not accommodating very ruff

the female flight attendant was racist towards me. I could tell she treated the two other passengers next to me with more softness.
