When this route gets cheap.
Fares bottom out in November around $301 and peak in February near $399, 33% dearer, across the 7 months we track. The cheapest itinerary we are tracking makes one stop and takes about 7.5 hours outbound, on a 7-night trip — ticketed under Vietjet, which on a connecting fare need not operate every leg. At $301 for 4,672 km each way, that works out to about $32 per 1,000 km flown. That is below the $43 per 1,000 km typical of medium-haul fares here. Across the 5 departure cities we track at a similar distance from Seoul, this fare ranks 3rd — 15% above the $261 from Bangkok. It is also the 2nd cheapest of the 9 routes of similar length we watch out of Singapore. The best time to be in Seoul: Apr–May · Sep–Oct.

Good to know
SIN → SEL, answered.
Is $301 a good price for Singapore to Seoul?
Only slightly. The seasonal median is around $340 round-trip and this fare is 11% under it. 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 Seoul?
Across 7 months of cached-fare history, Nov comes out cheapest on this route. The best months to actually be in Seoul are Apr–May · Sep–Oct — when those overlap, that's your window.
How far in advance should I book SIN → 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We do not publish a number for this, because we cannot measure it yet.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. What we can measure is which month is cheap: across 7 months of cached fares, Nov comes out lowest on this route. Our guide Why flight prices change covers what does move a fare.
Are there nonstop flights from Singapore to Seoul?
The current cheapest fares involve a connection, ticketed under Vietjet. We hold no nonstop fare on this route right now, which does not mean none flies — search your exact dates to see what does.
Are these prices guaranteed?
No — these are cached fares found on real searches (this one on 17 October). 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.
