Frequently asked questions

Is it cheaper to buy a plane ticket from Mascot Airport to USM last minute?
When it's time to book your flights, being prepared pays dividends. While it's possible to pick up a last-minute deal on a YQY to USM flight, tickets usually don't get cheaper as the departure date nears. Based on flight pricing and demand studies in 2022, we have found that the sweet spot to book a domestic flight is between 28 – 35 days in advance. For international trips it's three to four months.
What airports do you fly into for Koh Samui from Sydney?
Flights from Sydney to Koh Samui arrive at Ko Samui Airport (USM). Approximately 10 kilometers northeast of the heart of Koh Samui, it's a key gateway to this wonderful city. When you're ready to start sightseeing, Namuang Waterfall 1 and Hin Ta and Hin Yai should be at the top of your list.
