Cached-fare history: across 5 months, Sep is the cheapest for SIN → JKT. Best time to be there: May–Sep.
Fares bottom out in September around $147 and peak in December near $224 — a $77 spread across the 5 months we track. The cheapest itinerary we are tracking flies Transnusa nonstop and takes about 2 hours outbound, on a 3-night trip. At $147 for 906 km each way, that works out to about $81 per 1,000 km flown. That is above the $41 typical of short-haul fares here.

The median cached fare across this calendar is 3% higher than when tracking began on Aug 8 — $155 then versus $160 now, across 4 recorded snapshots. This is a calendar-level trend, so an individual deal above can be lower. The lowest single day we have seen here is $140, on Sep 17.
These are the only days we have a cached price for on this route so far — not the only days it flies. The search above covers any date.

SIN → JKT, answered.
Is $147 a good price for Singapore to Jakarta?
Only slightly. The seasonal median is around $180 round-trip and this fare is 18% under it, about $33. We do not call a drop notable until 20%, so this is an ordinary price for the route rather than a reason to hurry.
What is the cheapest month to fly from Singapore to Jakarta?
Across 5 months of cached-fare history, Sep comes out cheapest on this route. The best months to actually be in Jakarta are May–Sep — when those overlap, that's your window.
How far in advance should I book SIN → Jakarta?
We do not publish a number for this, because we cannot measure it yet. Answering it honestly means watching the same departure date on this route over many weeks as it approaches, and that archive is still filling up — so any "book N days ahead" figure here would be borrowed from somewhere else rather than measured. What we can measure is which month is cheap: across 5 months of cached fares, Sep comes out lowest on this route. See /guides/what-moves-a-flight-price/ for what does move a fare.
Are there nonstop flights from Singapore to Jakarta?
Yes — the current board includes nonstop fares (Transnusa). The outbound leg runs around 2 hours.
Are these prices guaranteed?
No — these are cached fares found on real searches (this one on September 1). Airlines reprice constantly, so the booking search re-checks the live price before you pay. Fresher finds are far more likely to still be available.
