How to Find Cheap Flights from the USA to Seoul
Book flights to Seoul 2-3 months ahead, compare prices across multiple search engines, and consider flying Tuesday-Thursday for the best deals. Expect to pay $800-1200 roundtrip from the West Coast, $1000-1500 from other regions.
- Start with flexible date searches. Use Google Flights, Kayak, or Momondo to search Seoul (ICN) with flexible dates enabled. Check prices across a 3-week window around your preferred departure. Tuesday, Wednesday, and Thursday departures typically cost $100-300 less than weekend flights.
- Compare multiple search engines. Check at least 3 platforms: Google Flights for overview, Skyscanner for budget carriers, and airline websites directly. Korean Air and Asiana often have competitive direct flights that don't show up on all booking sites.
- Consider one-stop options. Direct flights from LAX, SFO, and SEA cost $200-400 more than connections through Tokyo (NRT/HND), Vancouver (YVR), or Taipei (TPE). An extra 3-4 hours can save significant money.
- Book 60-90 days ahead. Prices typically bottom out 8-12 weeks before departure. Booking earlier than 4 months or later than 3 weeks usually costs more. Set price alerts if your dates are flexible.
- Check positioning flights. Flying to Seoul via LAX or SFO can be cheaper than connecting domestically first. Book separate tickets: a cheap domestic flight to the West Coast, then Seoul separately. Allow 4+ hours for connections.
- Consider alternative airports. Gimpo Airport (GMP) sometimes has cheaper domestic Korean flights, but international service is limited. Incheon (ICN) is your main target. On the US side, check both major airports in multi-airport cities.
- What's the cheapest time of year to fly to Seoul?
- Late January through early March and late April through early June offer the best prices. Avoid July-August (peak summer), October (fall colors), and December-January holidays when flights cost $300-500 more.
- Should I book directly with Korean Air or use a booking site?
- Check both. Korean Air and Asiana sometimes offer web-only deals, but booking sites often have better prices on partner airlines. Always compare the final price including baggage and seat selection fees.
- Are error fares to Seoul common?
- Occasional mistake fares pop up, usually $400-600 roundtrip. Follow @SecretFlying and Airfarewatchdog on social media. These deals last hours, not days, so be ready to book immediately if you see one.
- Is it cheaper to fly into Seoul or other Korean cities?
- Seoul's Incheon Airport has the most flight options and competitive prices. Busan is occasionally cheaper but with limited US connections. The domestic flight to Seoul adds cost and time that eliminates most savings.
