Cached-fare history: across 4 months, Sep is the cheapest for SEL → LAS. Best time to be there: Mar–May · Oct–Nov.
Fares bottom out in September around $844 and peak in July near $1,262 — a $418 spread across the 4 months we track. The cheapest itinerary we are tracking makes 2 stops and takes about 14 hours outbound, on a 3-night trip — ticketed under United, which on a connecting fare need not operate every leg. At $844 for 9,621 km each way, that works out to about $44 per 1,000 km flown. That is about the $44 typical of long-haul fares here. Across the 26 departure cities we track at a similar distance from Las Vegas, this fare ranks 16th — 49% above the $566 from Stockholm. For context, the middle fare among the 45 routes of similar length we watch out of Seoul is $698.

SEL → LAS, answered.
Is $844 a good price for Seoul to Las Vegas?
Only slightly. The seasonal median is around $1,040 round-trip and this fare is 19% under it, about $196. 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 Seoul to Las Vegas?
Across 4 months of cached-fare history, Sep comes out cheapest on this route. The best months to actually be in Las Vegas are Mar–May · Oct–Nov — when those overlap, that's your window.
How far in advance should I book SEL → Las Vegas?
We do not publish a number for this, because we cannot measure it yet.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 4 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 Seoul to Las Vegas?
The current cheapest fares involve a connection, ticketed under United. 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.
