Fares from Los Angeles to Seoul (USD)
Seoul is a year-round destination, but fares swing with Korea’s seasons and holidays. The summer peak (July–August), the spring cherry-blossom weeks and the Lunar New Year and Chuseok holidays are the priciest; late autumn and mid-winter outside the holidays are the cheapest. The table below shows when the route is busiest. We no longer print per-month fare estimates here, because they were never measured.
| Month | Demand |
|---|---|
| January | medium (Lunar New Year spike) |
| February | medium |
| March | medium-high |
| April | high (cherry blossom) |
| May | medium-high |
| June | high |
| July | very high (summer peak) |
| August | very high |
| September | medium (Chuseok spike) |
| October | low-medium |
| November | low |
| December | high (holidays) |
We do not quote a target fare for this route. Our price tracking holds no recorded observations for it, so a “typical” or “good deal” figure here would be an estimate dressed up as a measurement — so this page leaves it out rather than guess. The seasonal pattern above is the part we can stand behind; check the live fare for the number.
Airlines on this route
Nonstop (about 13¾ hours westbound):
- Korean Air — nonstop LAX–Incheon; the flag carrier, with a strong widebody fleet and a large onward network across Asia.
- Asiana Airlines — nonstop from LAX; well-regarded full-service product and frequent departures.
- Air Premia — a newer hybrid carrier flying the 787 nonstop; often the lowest nonstop fares, with a roomier economy than budget rivals.
One-stop (usually the cheapest, about 17–22 hours total):
- Japanese carriers via Tokyo or Osaka — smooth connections and competitive fares.
- Chinese carriers via Beijing, Shanghai or Guangzhou — often competitively priced.
- US carriers (Delta, United, American) connecting through their own or partner Asian hubs, or a Star/SkyTeam routing.
Because the one-stop carriers compete hard, they usually undercut the nonstops by $150–$350. If time and comfort matter, book a nonstop; if price is the priority, a single stop in Japan or China is the sweet spot.
When to book & how to save
- Book 2–5 months ahead for the best balance of price and choice; transpacific fares to Seoul rarely get cheaper in the final weeks.
- Avoid the peaks — July and August, the cherry-blossom weeks in early April, and the Lunar New Year and Chuseok holidays are the most expensive and busiest.
- Travel in late autumn (late October and November) for the lowest fares and pleasant, crisp weather in Korea.
- Consider Air Premia for a nonstop at a lower price, or a one-stop through Tokyo or a Chinese hub if you want the cheapest fare overall.
- Check checked-bag rules: the full-service carriers include generous baggage to Korea, but the lowest “lite” fares on hybrid and budget routings may not — compare the all-in price.
Arriving in Seoul
Almost all long-haul flights land at Incheon International (ICN), about 48 km west of central Seoul and one of Asia’s best-rated airports. The fastest way in is the AREX airport train: the all-stop line reaches Seoul Station in about 60 minutes for around $4, while the express is quicker for a little more. Airport limousine buses serve most districts and hotels for roughly $12–$14, and a taxi to the city runs about $55–$75 depending on traffic. A few domestic and regional flights use the older Gimpo (GMP) airport closer to the city.

Are there direct flights from Los Angeles to Seoul?

How far in advance should I book Los Angeles to Seoul flights?
