Cheap flights to Ko Samui in 2023/24 
from US, Canada, Australia, Europe, and Asia

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.

Most flight routes around Ko Samui are reasonably priced and short. For example, to fly from Ko Samui to Bangkok takes only one hour on a direct flight, at the cost of around 2000 bahts (~60 USD / ~85 AUD / ~55 EUR).

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.

Avoid Thai public holidays

Prices skyrocket in Ko Samui during popular Thai holidays – adjust travel dates to avoid expensive tickets. Cheap flights to Ko Samui are non-existent during popular “red days” such as Songkran (12-15 April), Coronation Day (5 May), Vesak (26 May), Chulalongkorn Day (23 October), and New Year’s Eve (31 December).

How to book SuperDeals?

At the Air Traveler Club, our go-to solution for finding cheap airfares to Ko Samui is Google Flights. Every time we send SuperDeals to our 110,000 members (see some examples), we include links to Google Flights so that each deal can be booked immediately.

Google Flights then showcases various options for booking the deal: you can almost always book directly with the airline (by cutting out the middleman) or – alternatively – with an OTA that offers the same flight at a similar price. Once you have chosen your booking option, you will be redirected to the external website where you can finalize your ticket purchase.

One of Google Flights’ standout features is a color-coded bar that appears underneath the booking options. It provides a visual representation of the price in comparison to the typical fare (for the same route, class, and airline) – indicating whether it is lower, average, or higher.

If the marker falls within the green zone (“price is low”) don’t hesitate to secure this deal as it is significantly – 40% to 80% – cheaper than average and unlikely to drop further.

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.

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 around 60-90 days before the departure date.

Get cheaper business class by bidding on airline upgrades

A growing number of airlines are auctioning upgrades to their business class seats. Once you book your economy ticket to Ko Samui, you can offer to pay a bit more in an attempt to get a premium seat. 2-3 days before your flight, visit the airline website and place a “blind” bid for an upgrade by providing your Booking Reference number.

There’s usually a minimum bid amount. If you win the auction, you’ll be informed by email, and your seat will be upgraded.

Among the airlines that allow bidding for seat upgrades are: Air Canada (AC Bid), Air New Zealand (OneUp), Cathay Pacific (Upgrade Bid), Etihad Airways (Bid To Upgrade), Fiji Airways (Bula Bid), Garuda Indonesia (BidUpgrade), Hawaiian Airlines (Bid Up), LATAM (Cabin Upgrade),  Lufthansa (Bid Upgrade), Royal Jordanian (Go Crown), Qantas (Bid Now), SAS (SAS Upgrade), Singapore Airlines (mySQupgrade), SriLankan Airlines, and Virgin Australia (UpgradeMe).

Why should you book an early morning flight to Ko Samui

It is a seemingly simple but often overlooked strategy: fly at dawn for smoother travel and cheaper tickets. Booking an early morning flight to Ko Samui can pay off in numerous ways:

1. Cheaper airfares. Early morning flights – between 4 am and 8 am – are usually cheaper than other day schedules. Airlines often offer discounts on their first flight of the morning (up to 15-20%) simply because of lower demand – most people are not willing to go to the airport so early.
2. Lower chance of delay. The thin traffic in the morning leads to fewer delays – all the flights from the night before have already landed, and there is no other air traffic to contend with. Air traffic and delays get worse throughout the day – starting around 8-10 am and reaching a peak at 4-6 pm. If you are flying to Ko Samui with a connecting flight, arriving on time at your layover airport may be critical to catching your next flight!
3. Fewer crowds at the airport. By heading to the airport before rush hour, you can at least halve the time spent in city traffic. With fewer travelers at the airport, there will be no long lines at the check-in and security, and waiting areas will be less crowded.

   

4. Less turbulence. Early morning flights offer a smoother ride, with less turbulence. Thunderstorms and unstable air, which can cause turbulence (including its worst kind – convective turbulence) are more likely to occur in the afternoon.
5. Fresher crew. You’ll be flying with a crew that has had a good night’s sleep and is mentally ready to provide better service and ensure a safer flight experience.
6. Cleaner plane. On its first flight of the day, your aircraft will be as sanitary as possible. Airlines generally take extra care to thoroughly clean planes between flights, but boarding that morning flight gives you the greatest chance of a spotless plane.

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

Airlines often have varying prices for flights to Ko Samui from different airports – even if they are in close proximity to one another. So don’t limit yourself to just your nearest airport. The neighboring cities may have lower-priced flights that include a layover at Ko Samui, or may even have direct flights that are more budget-friendly.

For example, if you’re looking to fly from Paris to Ko Samui, it may be worth checking prices for flights departing from London, Frankfurt, Amsterdam, or Rome. Yes, you may have to fly a few hundred kilometers to these hubs, but domestic low-cost airlines like EasyJet, RyanAir, or WizzAir will happily take you there for less than €100.

The same goes for long-haul flights to Ko Samui from anywhere in the world. By broadening your search to include neighboring airports, you may discover lower-priced options that can save you hundreds of euros!

Fly now, pay later

Book Now Pay Later (BNPL) plans for flights have become a popular trend in the travel industry, allowing travelers to book flights and pay in installments. Among the airlines that offer this option are American Airlines, Delta Air Lines, Emirates, Qatar Airways, Qantas, Turkish Airlines, and United Airlines. They partner with external financial companies to offer their loan services on the checkout page.

The BNPL plans come with varying terms and fees. Some may be interest-free but have fees for late-payments and require forced autoplay on your bank account, while others may have high annual percentage rates (up to 30-40% APR).

When considering BNPL financing for your flight to Ko Samui, it’s crucial to carefully evaluate the pros and cons, and thoroughly review the terms and conditions.

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.

Lost luggage prevention: Essential tips

Every year, airlines handle millions of bags, and a small percentage of these bags never make it to their final destinations. Globally, airlines mishandle around 0.7% of bags checked in, which translates to seven bags out of every 1,000. Losing the luggage on your trip to Ko Samui can be a frustrating and stressful experience, but there are steps you can take to minimize the risk of this happening to you.

1. Use GPS-Trackers. A luggage tracking device such as Apple AirTag or Samsung Galaxy SmartTag comes with a smartphone app and is an excellent way to locate your bag if it goes missing.

   

2. Label your luggage with your name, address, phone number and the name of your destination airport in Ko Samui. Put these details inside the case as well.
3. Remove old tags. Tags are printed with a barcode for identification and tracking, so the old tags from previous flights can confuse baggage handlers and conveyor belt scanners.
4. Avoid tight layovers. Give yourself and your luggage time to get aboard the next plane by picking a flight to Ko Samui with a longer layover.
5. Don’t overstuff your suitcase. Heavy bags are more likely to get damaged and stuck on the belts, causing the bag to be misdirected.
6. Make your bag stand out. After arrival at Ko Samui airport, most people just want to grab their luggage and get out of the airport as soon as possible. In their haste, a case of mistaken identity can sometimes occur.
7. Take a picture of your bag and the contents, and keep it on your phone. This can be helpful if you need to make a claim for lost or damaged items.
8. Use a TSA-approved luggage lock. This will secure your bags and will help deter theft.
9. Keep your valuables in your hand luggage. The airline liability is notoriously low (around €1,000 in most cases) and it usually doesn’t reflect the actual value of the baggage content.
10. Consider purchasing travel insurance. It can act as a safety net as it can often cover the full value of your luggage. Travel insurance may also reimburse you for any emergency purchases you need to make while you wait.

Hidden-city ticketing hack

Hidden-city ticketing is a less-known money-saving tactic where you buy a plane ticket with a layover, with the intention to get off at the layover rather than the final destination. For example, a flight from New York to Tokyo might be $600, but a similar flight from New York to Singapore with a layover in Tokyo might be only $350. Choosing the latter and ending the trip in Tokyo would save you $250.

It seems counterintuitive that a fare from A to C via B could possibly be cheaper than a simple fare on a shorter route from A to B. However, airlines use dynamic, computer-driven price models calculated with little human intervention, and such deals happen quite often.

Booking a hidden city ticket isn’t as easy as booking a standard itinerary. There are some things to be aware of: (1) don’t check baggage — bring only hand luggage that can fit under the seat or an overhead compartment; a large checked bag will end up in the final destination C; (2) don’t use it for return flights — airlines often void any subsequent tickets if any segment of the first ticket is missed; (3) Do not overuse this tactic with the same airline — hidden-city ticketing is legal but airlines don’t like it and may try to punish you; (4) Don’t associate your frequent flyer account — the airline might invalidate any miles you’ve accrued with them.
