KAYAK’s top tips for finding a cheap flight from Chiang Mai to Ko Samui

  • Looking for a cheap flight? 25% of our users found flights on this route for ฿9,927 or less one-way.
  • Thai AirAsia and Bangkok Airways combine to offer one of the most affordable flights between Chiang Mai (CNX) and Koh Samui (USM), but these flights have a self-transfer stopover where you must change from Don Mueang Airport (DMK) to Bangkok Suvarnabhumi (BKK). There's a free shuttle available from Don Mueang so don't spend additional money on a taxi transfer.
  • Direct flights are the fastest way to get to Koh Samui from Chiang Mai but it's also the most expensive flight. Several single-stopover flights work out cheaper than direct trips. Both Bangkok Airways and Thai Vietjet Air offer single-stopover flights via Bangkok Suvarnabhumi Airport.
  • The quickest way to get to Chiang Mai Airport from the city centre is to arrange an airport shuttle or take a local taxi. If you want to experience what it's like travelling like a local though, jump on one of the group taxis, songtaews, with red and yellow lines. These travel on a loop to and from the airport and are much cheaper.
  • If you're taking a flight with an airline other than Bangkok Airways or Singapore Airlines, be aware that your stopovers are likely to be self-transfer stopovers. You'll need to collect and check in again at each stop. Ensure your stopover time is long enough in case of any delays since you'll be responsible for any additional costs if you miss your connecting flight.
  • For those of you looking to explore South East Asia, consider catching a flight with Singapore Airlines that offers a long stopover at Singapore Changi Airport (SIN) en route. You can venture out and explore the airport and parts of Singapore before heading back to catch your connecting flight. There are often flights with stopovers as long as 20 hours.
