Cheapest months to fly to Seoul
Seoul fares follow a pretty predictable rhythm once you know what's driving them. Summer (late June through August) is expensive — Korean school holidays overlap with peak tourism season, and business traffic to the financial district never really lets up. Cherry blossom season in April spikes prices almost as badly, because the internet has fully ruined that secret. The sweet spots are May (after the blossoms, before the humidity), and November, when the crowds thin out but the city's still comfortable. Winter fares dip, though the Lunar New Year window in late January or early February will cost you if you're not paying attention.
Why visit Seoul?
Seoul rewards the obsessively curious. The food scene alone justifies a long-haul ticket — from the basement restaurant floors of Lotte and Shinsegae department stores (genuinely better than anything at street level) to the raw seafood markets in Noryangjin. Culturally, you've got 600-year-old palaces sharing a city block with K-pop entertainment companies running public auditions on weekdays. Hikers come for Bukhansan National Park, which sits improbably inside the city limits. Business travelers are here for Samsung, Hyundai, LG, and a financial sector that doesn't sleep. Incheon International Airport itself — consistently rated among the world's best — handles 162 non-stop destinations, which tells you something about Seoul's position in global commerce and travel. It's a city that functions at an unusually high operational tempo, and that energy is contagious.

Tips for getting a cheap fare to Seoul
May is the month I'd target first — shoulder season pricing, good weather, no major Korean holidays eating into seat availability. If you're flying from Los Angeles, set fare alerts for both ICN and check whether a positioning flight to Tokyo (NRT) or Osaka (KIX) opens up a cheaper two-leg option, since both are popular non-stop routes from Incheon with strong competition. Book six to eight weeks out for the best window; last-minute fares to Seoul rarely reward patience. Visa-wise, most Western passport holders get 90 days visa-free. The Korean Won is your friend right now — carry some cash, because smaller restaurants outside tourist areas often don't bother with cards.
