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 makes one stop and takes about 9 hours outbound, on a 5-night trip — ticketed under Cathay Pacific, which on a connecting fare need not operate every leg. At $447 for 4,687 km each way, that works out to about $48 per 1,000 km flown. That is above the $39 typical of medium-haul fares here. Across the 5 departure cities we track at a similar distance from Seoul, this fare ranks 5th — 2.6× the $171 we hold from Bangkok. That puts it in the cheaper half of the 29 routes of similar length we watch out of Delhi, where the middle fare is $461. We have 2 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.

DEL → SEL, answered.
How far in advance should I book DEL → 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We do not publish a number for this, because we cannot measure it yet.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 Delhi to Seoul?
The current cheapest fares involve a connection, ticketed under Cathay Pacific. Nonstop options exist on many dates at higher prices — check the live search for your exact dates.
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.
