Which airlines fly direct from Koh Samui to Bangkok?

You can catch direct flights from the Samui International Airport (USM) on the island of Koh Samui to the Suvarnabhumi Airport (BKK) in Bangkok on airlines including Bangkok Airways and Garuda Indonesia. It is unlikely you will find a non-stop flight from USM to Don Mueang International Airport (DMK) in Bangkok. From Surat Thani International Airport (URT) on the mainland of Southern Thailand, you can book non-stop flights to BKK on Thai Smile and non-stop flights to DMK on Thai Lion Air. From USM to BKK, you can book a one-stop flight on Bangkok Airways with a stop in Phuket City. From USM to DMK, Bangkok Airways combined with either Nok Air or Thai AirAsia offers one-stop flights with a stop in either Phuket City or Chiang Mai. It is unlikely that you will find a one-stop flight to Bangkok that departs from URT. What is the best way to get in and out of airports in Koh Samui and Bangkok? On the island of Koh Samui, you will not find many options for public transportation in order to get to Samui International Airport (USM). However, one of the best options for transport to USM on the island is a local minivan that you could take, for instance, from the Koh Samui Nathon Pier to USM in approximately 11 minutes. Other options for getting to USM include getting a taxi, a town car, or a local shuttle. From Surat Thani to Surat Thani International Airport (URT), you can catch a bus that can get you to the airport in approximately 52 minutes. Other options include taxi and town car. To get from Suvarnabhumi Airport (BKK) into the city center of Bangkok, your best option is to take a City Line Airport Rail Link, which will take about 26 minutes. A bus departing from the BKK will take about 52 minutes to get you into Bangkok. Other options for getting from BKK into the city include taxi and town car. To get from Don Mueang International Airport (DMK) into Bangkok, you can take an A1 bus, which takes about 20 minutes, or a taxi, which is much more expensive, and takes about 22 minutes. What are the benefits of the different airports in Koh Samui and Bangkok? Departing from Samui International Airport (USM) as opposed to Surat Thani International Airport (URT) has two significant advantages. First, you can find more flight options from USM in terms of departure and arrival times, flight duration, and price. Second, USM is actually on the island of Koh Samui. Since URT is on the mainland of Southern Thailand, to depart from that airport, you would first have to take a journey combining buses and a ferry in order to get to the airport. However, if you happen to be on the mainland already, URT might be a convenient airport, especially if you can find a flight to Bangkok that works for you. In Bangkok, Suvarnabhumi Airport (BKK) tends to have more flight options and services and amenities than Don Mueang International Airport (DMK). However, DMK is a smaller airport and in general, more manageable to navigate. Which cities can you get to from the different airports in Bangkok? The city of Bangkok is your gateway to exploring Thailand. About 50 miles north of Bangkok, you can find Ayutthaya, the ancient capital of Siam, where you can explore ancient ruins. To get from Suvarnabhumi Airport (BKK) to Ayutthaya, you can take Line 554 Public Van and then switch to a #201 train in Lak Si. From Don Mueang International Airport (DMK), you can take a taxi or a train. At Samut Prakan, about 20 miles southeast of Bangkok, you can visit Buddha statues, gardens, and monuments. From BKK, you can take a Public Van, taxi, or train. From DMK, your best option is a taxi. Both airports have car rental facilities on-site. Driving a rental car is a great way to visit these cities as well as the idyllic coastal city of Koh Samet, about 125 miles southeast of Bangkok.

We always recommend checking with your airline or a trusted third party such as IATA to get advice.
