Frequently asked questions

Is it cheaper to buy a plane ticket from Changi Airport (SIN) to Gatwick Airport (LGW) last minute?
Being a spontaneous soul is a fantastic way to explore the world, but it isn’t always the best method to pick up a bargain airfare. It’s better to book your SIN to LGW journey 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. We recommend saving that spontaneity for when you’re discovering LGW!
