Thailand is open to international tourism

International travelers may freely enter Thailand if they can provide proof of vaccination. Unvaccinated visitors must present a negative PCR test up to 72 hours before departure. There is no Covid test on arrival or during the stay in Thailand. Health insurance is not compulsory but recommended.

64 nationalities under the Visa Exemption Program can enter Thailand without a visa and stay for up to 30 days. Foreigners may also apply for a Tourist Visa from the Thai embassy or consulate.

Transit through Thai airports is allowed as long as you remain in the transit area in the airport. Ensure that your connecting flight is booked on the same itinerary and ticket.



Arriving in Ko Samui

  • If you are flying to Ko Samui from abroad, you will most likely land at one of its biggest international airportsits main international airportSamui Airport USM, located on the northeast coast of the island of Koh Samui in the Gulf of Thailand.

    The airport is privately owned and operated by Bangkok Airways – most flights to and from the island are operated by this carrier (often under code-sharing agreement with other airlines). USM has two terminals, domestic and international, and is known for its distinctive open-air layout.

    In close proximity to Samui Airport, passengers can conveniently access two major piers for island-hopping adventures. The Big Buddha Pier, situated nearby, offers ferry services to Ko Pha-ngan, while high-speed ferries to Ko Tao and Chumphon are available at Maenam Beach Pier, located approximately 6 km northwest of the airport
    .

    These are also the best (and the cheapest) airports to fly into Ko Samui. As they are used by many airlines serving the same routes, the competition for passengers is fierce – with decreased airfare as a result.
  • Once in Ko Samui, take advantage of frequent intercity flights operated by domestic airlines such as Thai Airways, Bangkok Airways, Nok Air, Thai Lion Air, Thai Smile. Those in-country carriers typically offer lower fares, operate from smaller airports located closer to city centers (you save on ground transportation), and provide flexible schedules – with a wide range of departure times.
  • Planning to explore the region? Popular destinations near Ko Samui can be easily reached with regional low-cost carriers (LCCs) by the likes of Bangkok Airways, and Scoot. If you have a layover in Ko Samui and plan to fly only a short distance to one of its neighboring countries, these budget airlines are an excellent way to save money. However, the “no-frills” carrier may not provide free checked baggage allowance, complimentary food, in-flight entertainment systems, and fast customer support. You may not even get to choose your seats, unless you pay extra.

Low-cost flights from Ko Samui

Stay ahead of the game. Fly to popular destinations at a fraction of the regular fare.

Duty-free rules

Thailand is serious about the duty-free concession. There is a limit for bringing in certain items. Alcoholic drinks such as wine, spirits or beer cannot exceed one liter per person, and you can carry only 200 cigarettes (or 250g of tobacco). In addition to personal items, you may also carry items in reasonable quantity up to a value of 20,000 baht (~USD 550 /  AUD 810).

Anything above those limits must be declared – at the Samui Airport, head to Red Lane to declare your goods.

The cheapest time to fly to Ko Samui

Ko Samui is a relatively affordable destination all year round, though travelers may find the best bargains on flights during the low (monsoon) season – which runs from July to September.

During these months Ko Samui experiences less-pleasant weather conditions compared to the dry, hot months of November to May. Despite the less-than-ideal weather, the off-peak season promises smaller crowds and big savings: flights, hotels, tours, activities, and local food are significantly cheaper compared to the high season.

Ko Samui, like most of Thailand, experiences its peak tourist season from November to March (or even into April and May) – it’s the time when airfares skyrocket, so remember to book your flights well in advance to avoid overpaying.

When planning your visit to Ko Samui, try to avoid national holidays, when flight and hotel prices soar (even during the off-peak season).

Know your time zone

Thailand uses only one time zone across the country – Thailand Standard Time (THA) or Indochina Time (ICT) – which is UTC+7 (GMT+7). As a result, clocks in Ko Samui are 7 hours ahead of London and 11 hours ahead of New York. The country shares the same time zone with Cambodia, Laos, Vietnam, and Western Indonesia. It does not have an associated daylight saving time.

When checking flights and airport transfer times, ensure you know the local time zones. The departure time on your plane ticket is always listed based on the time zone of the departure airport. We suggest resetting your watch during the flight – it will help your brain adjust to the new time zone and to deal with jet lag.

Use the Thai Post Office to send your bag ahead

You can walk into a post office in any Thai town and send a suitcase ahead to your next destination in Thailand. Just contact your next hotel or Airbnb to notify them of the upcoming package delivery. Even a large, heavy suitcase should cost you no more than 300 Bahts (less than $10).

Use Grab to get around island

Uber is no longer available in Thailand – it ceased business in April 2018 and has been replaced by its Asia alternative – Grab. It’s a good way for a cross-city journey: the cars are safe, secure and usually air-conditioned. Similarly to Uber, it has fixed distance-based fees, so drivers can’t overcharge you for journeys.

If you don’t have Grab Taxi yet, download it for your Ko Samui vacation and set up your account, payment options, etc before arriving.

Use Thai budget airlines

It can be time-consuming and uncomfortable to travel on overnight buses or trains in Thailand. Opt for domestic air travel instead, as it is usually cheap, easy, and convenient.

The cheapest flights can be found on Thai budget airlines – Nok Air, Thai Air Asia, Thai Lion Air, Thai VietAir, and Thai Smile.

Long waiting times when calling the helpline?

Social media is usually a faster way to reach the airline when a problem arises. Use Twitter or Facebook Messenger to contact the airline customer service and get a response and solution within minutes (see detailed guides for Thai AirAsia, Thai LionAir, Singapore Airlines, and others).

When it comes to Twitter there’s one more trick to get in touch with the airline faster: mention the airline in a tweet about your issue (add “@airline_handle”, for example: “@ThaiAirways”). The social media team will often notice it immediately, ask you for a direct message, and respond privately.

Last-minute flights to Ko Samui. The real cost of convenience.

Last-minute flights are often touted as a great way to save money, but the reality is far from it. Booking last-minute flights to Ko Samui almost always never works out. The convenience of being able to book a flight on the fly is a dangerous game of chance, and you will most likely end up paying significantly higher than booking in advance.

Last-minute flight cost spike
Late booking penalty: The flight prices rise as departure draws near. Last-minute flights are almost always more expensive than booking in advance.

The common perception may be that airlines decrease ticket prices to fill empty seats as the departure date approaches. However, the truth is that airfares depend on demand. Based on years of research and current customer data, the airlines know what people are willing to pay for specific flights and dates. They are also well aware that people are willing to pay a premium for flights they need to take immediately. To make the most money, the airline will sell its cheapest fares first and then increase the prices right before the flight to take advantage of business travelers and others who are willing to pay the premium price for late booking.

Occasionally, airlines can put some seats on sale to fill the remaining seats, but these are for unusual times and unpopular places. Popular destinations and dates around peak travel times tend to sell out quickly.

Planning ahead is key to securing a good deal on your flight. Last-minute flight deals are hard to come by, so as soon as you have a tentative travel timeline, book your flight. The earlier you book, the more likely you are to save money. If you are looking for a good deal, the best time to book your flight to Ko Samui is 2-8 months before the takeoff.

Looking for the best deals for Ko Samui? Check different departure airports.

“Hot seats” on long-haul flights

However, if you’re about to take a long-haul flight to Ko Samui, those “hot seats” are worth considering – expect to pay $50-$100, which is much less than upgrading to Premium Economy.

If you want to choose your seats, do this early (ideally during the booking) for a more extensive selection of available options.

This limit reflects the complexity of managing larger groups, which require personalized service and more time to coordinate.

If you’re open to different airlines or want more personalized service, a travel agent may be a better choice. Travel agents may have access to discounted group rates to Ko Samui and can help with logistics and scheduling.

Proof of onward travel – a simple hack

Travelers who go on long trips often don’t have a set itinerary and fly on one-way tickets. The problem? For many APAC countries, proof of onward travel is a legal requirement. If you arrive at the airport without an onward ticket (from Thailand to another country), you’ll either be forced to buy one online or forbidden from boarding the plane altogether.

The cheapest solution? Renting an onward ticket! Use the websites such as OneWayFly or OnwardTicket to get a flight reservation for a limited amount of time (usually 2 to 14 days). They work by actually booking you on a real flight out of Thailand and giving you a confirmable flight reservation with a PNR (Passenger Name Record) under your name. After the time limit, your spot on the flight is automatically canceled. Such “temporary tickets” tend to cost anywhere from $10 to $20.
