Cheapest Time to Fly to Singapore (and the Most Expensive)

Flights to Singapore can swing a lot based on timing. For US travelers, prices usually climb when winter travel demand spikes, holiday weeks stack up, and seats on long-haul routes fill fast.

Quick Take

• Cheapest time to fly to Singapore: late April–June and September–early November
• Most expensive time to fly to Singapore: late December–early January, plus many January–March weeks

Cheapest Time to Fly to Singapore

These windows tend to be the most deal-friendly—lower demand, more open seats, and better odds of catching a real price drop.

Late April to June (shoulder-season value)

After early-year travel demand starts fading, prices often loosen up. Late spring into early summer can be one of the better stretches to find cheaper flights to Singapore.

Money-saving tip: Midweek departures: Tuesday–Thursday often price better than weekend-heavy dates.
Heads-up: Late June: prices can start creeping up as summer travel ramps.

September to Early November (fall deal stretch)

Once peak summer travel cools off, fares often soften. September and October can be especially good for deal-hunting, with early November sometimes staying deal-friendly before late-year demand builds.

Money-saving tip: Early November: often prices better than the last two weeks of the month.
Heads-up: Conference-heavy weeks: certain event weeks can tighten availability and bump fares.

Mid-January (select weeks)

Some January dates can be a sneaky opportunity—mainly after the initial New Year travel rush clears. It’s not always cheap, but when it dips, it can dip hard.

Money-saving tip: Watch one-week swings: shifting by 7 days can change the fare a lot on long-haul routes.
Heads-up: Holiday timing: if your dates overlap major regional holidays, pricing can jump.

Most Expensive Time to Fly to Singapore

These stretches are when flights to Singapore usually price high—because demand stacks fast and cheaper seats disappear early.

Late December to Early January (holiday surge)

This is often the most expensive time of year to fly. Late-December departures and early-January returns regularly cost the most.

Peak within peak: The week after Christmas through the first week of January.

January to March (winter peak weeks)

Many winter weeks price high—especially when travelers chase warm-weather getaways and fixed-date trips. If your schedule is locked, this can be a tough stretch to find deals.

Peak within peak: February and early March can be especially stubborn for pricing.

July to August (summer peak)

Summer can be hit-or-miss. Some weeks are reasonable, but peak summer travel patterns can still push prices up—especially if you need weekend-to-weekend dates.

Peak within peak: Late July into mid August often runs higher.

Want Great Timing Without Peak Flight Prices?

If you want Singapore when it still feels like a great time to go—but you don’t want to pay the highest airfare—these windows often land well:

• Late April to May: often cheaper than winter, with solid timing
• Late September to October: frequently better fare odds than summer peak weeks
• Early December: sometimes a deal window before late-December prices take off

Money-saving tip: Try midweek-to-midweek: it’s one of the simplest ways to cut cost without changing the whole trip.

Best Booking Window for Cheap Flights to Singapore

Because Singapore is long-haul from the US, the best deals usually go to people who track early and book when the drop shows up.

• Lower-demand periods: start tracking 3–7 months ahead
• Peak periods (late Dec–Mar): start tracking 6–11+ months ahead

Money-saving tip: Lock the fare when it’s good: long-haul deals can vanish fast once a route starts filling up.
