Frequently asked questions

Is it cheaper to buy a plane ticket from Galileo Galilei Airport to Ko Samui Airport (USM) last minute?
Being spontaneous is a fabulous way to travel, but it isn't always the smartest way to land a cheap flight. It's better to book your Galileo Galilei Airport to USM trip ahead of time rather than waiting till the last minute. Based on flight pricing and demand studies in 2022, we have found that the best time to book domestic flights is between 28 – 35 days ahead of the departure date, and international flights three to four months in advance. You can unleash your spontaneous side when you arrive at your destination!
