Cached-fare history: across 6 months, Oct is the cheapest for LA → SEL. Best time to be there: Apr–May · Sep–Oct.
Fares bottom out in October around $512 and peak in December near $1,199 — a $687 spread across the 6 months we track. The cheapest itinerary we are tracking makes one stop and takes about 15.5 hours outbound, on a 24-night trip — ticketed under China Eastern, which on a connecting fare need not operate every leg. At $512 for 9,586 km each way, that works out to about $27 per 1,000 km flown. That is well under the $44 that long-haul fares on this board typically run. Across the 30 departure cities we track at a similar distance from Seoul, this fare ranks 3rd — 6% above the $484 from Istanbul. That puts it in the cheaper half of the 42 routes of similar length we watch out of Los Angeles, where the middle fare is $687.

How far in advance should I book LA → 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We do not publish a number for this, because we cannot measure it yet.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 6 months of cached fares, Oct comes out lowest on this route. See /guides/what-moves-a-flight-price/ for what does move a fare.
Are there nonstop flights from Los Angeles to Seoul?
The current cheapest fares involve a connection, ticketed under China Eastern. 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.
