Frequently asked questions

Is it cheaper to buy a plane ticket from Singapore Airport to KOS last minute?
Being the spontaneous type is a great way to travel the world, but it isn't always the best way to pick up a cheap fare. Consider booking your Changi Airport to KOS trip well 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. Leave all that spontaneity for when you're discovering KOS!
