How to Travel from Bangkok to Koh Samui

Getting to Koh Samui from Bangkok involves a straightforward journey, but you’ll have several routes to choose from—each with its own benefits. Below is everything you need to know.

1. Flying from Bangkok to Koh Samui: The Fastest and Easiest Option

Travelling from Bangkok to Koh Samui by plane is the quickest and most comfortable method. Koh Samui Airport (USM) is privately owned and operated by Bangkok Airways, which keeps it beautifully landscaped and surprisingly calm compared to other airports in Thailand.

Airlines Operating Bangkok → Koh Samui

• Bangkok Airways (Suvarnabhumi Airport – BKK)
• Thai Airways (limited codeshare flights via Bangkok Airways aircraft)

Because Bangkok Airways controls most traffic to USM, prices are typically higher than domestic flights to other islands like Phuket or Krabi. Still, the convenience is unbeatable.

Flight Duration – 1 hour 5 minutes from Bangkok to Koh Samui
It’s a quick hop, making this ideal for short holidays or travellers who want maximum beach time.

Typical Prices

Prices vary based on season, but here’s what you can expect:

• Low season: 3,000–4,500 THB one-way
