Looking for cheap flights from Kolkata to Seoul? FlightGPT compares live CCU to ICN fares across every connected source — Indian carriers, Gulf hubs, OTAs and trusted travel agents — and shows the cheapest options side by side. Whether you want a Kolkata to Seoul non-stop tomorrow, a last-minute weekend deal or the lowest price three months out, every active Kolkata-Seoul fare is one search away.
Thai Airways via Bangkok, Singapore Airlines via Singapore, and Cathay Pacific via Hong Kong are the primary options. IndiGo's expanding Asian network from CCU may offer connections through Bangkok or Singapore. Korean Air and Asiana operate from Delhi with non-stops to ICN, so a CCU–DEL hop followed by a DEL–ICN sector is another possibility. Expect ≈ 2–4 one-stop routings daily.
Seoul's shoulder seasons — late March to early May and October — deliver pleasant weather and often lower fares. Summer (July–August) and cherry blossom season (late March) can push prices up. From Kolkata, avoiding Durga Puja and Diwali periods also helps. Booking 6–10 weeks ahead is advisable for economy seats. Indicative fares are live on FlightGPT as of May 2026.
Via Bangkok, CCU–BKK is ≈ 2.5 hours and BKK–ICN about 5.5 hours, totalling ≈ 10–12 hours with a layover. Singapore Airlines via SIN adds more flight time but offers excellent connections. Via Hong Kong the profile is similar at ≈ 9–11 hours total. Early morning departures from Kolkata can get you to Seoul the same evening, given the 3.5-hour time gain heading east.
Full-service carriers like Thai Airways, Singapore Airlines, and Cathay Pacific typically include 23–30 kg checked baggage on economy tickets. Low-cost connections may limit this to 20 kg or less. Carry-on is 7 kg on most airlines. Indicative fares are live on FlightGPT as of May 2026.
CCU handles all departures from its integrated terminal. Incheon International Airport (ICN) is South Korea's main gateway, located ≈ 65 km west of central Seoul. The AREX express train reaches Seoul Station in ≈ 43 minutes. ICN consistently ranks among the world's best airports for facilities and transit experience. Terminal 1 handles most foreign carriers; Terminal 2 is used by Korean Air and partner airlines.
Indian passport holders generally need a visa or K-ETA (Korea Electronic Travel Authorization) to enter South Korea. The K-ETA can be applied for online and is valid for multiple entries over two years, but eligibility conditions change — verify before booking. A traditional consular visa is the fallback if K-ETA is not available. See /visas for current rules.
With one stop, total journey time is ≈ 8–12 hours depending on the connection hub and layover length.
