Are error fares to South Korea common?

Korean airline error fares pop up 2-3 times per year, usually on Korean Air or Asiana. Follow Secret Flying or Scott's Cheap Flights for alerts. Most honor the tickets if booked quickly.

Should I book separate tickets to save money?

Only if the savings are substantial ($400+) and you have 3+ hours between flights. Seoul Incheon is efficient, but you'll need to collect bags and recheck them, plus risk missing connections if delayed.

Is it cheaper to fly into Tokyo then take budget airlines to Seoul?

Sometimes. Check flights to Tokyo Narita, then Peach or Jetstar to Seoul. This can save $200-300 but adds 6-8 hours total travel time. Only worth it for flexible travelers on tight budgets.

Do Korean airlines offer better deals to Seoul?

Korean Air and Asiana occasionally offer competitive prices during their sales (usually spring and fall). Their service is excellent, but they're rarely the cheapest option. Check during their promotion periods.

How to find cheap flights to South Korea

Book flights to South Korea 2-3 months in advance, fly Tuesday-Thursday, and consider Seoul's Incheon (ICN) over Gimpo for international deals. Budget carriers like Scoot, Cebu Pacific, and Jin Air offer the best prices, especially with layovers in Southeast Asia or Japan.

Choose your airport strategically. Fly into Seoul Incheon (ICN) for the most flight options and competitive prices. Busan (PUS) has fewer international flights but can be cheaper if you're staying in the south. Avoid Gimpo (GMP) for international flights—it's mostly domestic.
Time your booking window. Book 8-12 weeks before departure for the best prices. Avoid booking more than 4 months out (prices haven't dropped yet) or less than 3 weeks out (you'll pay premium rates).
Target the right travel days. Fly Tuesday, Wednesday, or Thursday for the cheapest fares. Avoid Friday-Monday departures. Red-eye flights and early morning departures (before 8am) are typically $100-200 cheaper.
Consider budget carriers with layovers. Scoot (via Singapore), Cebu Pacific (via Manila), and AirAsia (via Kuala Lumpur) offer flights $300-500 cheaper than direct options. Jin Air and T'way Air are Korean budget carriers worth checking for regional connections.
Use the right search strategy. Search Google Flights first to see the price landscape, then book directly with airlines. Clear your browser cookies between searches. Try searching from Seoul to your city (reverse search) to spot deals you might miss.
Avoid peak periods. Skip Korean holidays: Chuseok (late September/early October), Lunar New Year (January/February), and Golden Week (early May). August is peak summer—fly in June or September instead for $200-400 savings.
