Best time to be in Seoul: Apr–May · Sep–Oct. Fare history for this route is still thin, so we make no seasonal call yet.
The cheapest itinerary we are tracking flies T'way Air nonstop and takes about 7.5 hours outbound, on a 6-night trip. At $264 for 5,297 km each way, that works out to about $25 per 1,000 km flown. That is well under the $39 that medium-haul fares on this board typically run. Across the 4 departure cities we track at a similar distance from Seoul, this fare ranks 2nd — 16% above the $227 from Singapore. It is also the 2nd cheapest of the 11 routes of similar length we watch out of Jakarta. We have 3 months of cached prices for this route so far — not enough to call a fare cheap or expensive, so we publish the price without a percentage.

JKT → SEL, answered.
How far in advance should I book JKT → Seoul?
We do not publish a number for this, because we cannot measure it yet.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. See /guides/what-moves-a-flight-price/ for the levers we can measure.
Are there nonstop flights from Jakarta to Seoul?
Yes — the current board includes nonstop fares (T'way Air). The outbound leg runs around 7.5 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.
