Looking for cheap flights from Delhi to Seoul?

Air India and Korean Air each operate a daily non-stop (7x weekly) on the Boeing 787 Dreamliner into Seoul Incheon — giving roughly two direct departures a day between them. Both offer full service; Korean Air adds a deep onward network across East Asia and the Americas from Incheon. One-stop alternatives run on Asiana, Singapore Airlines via Singapore and Cathay Pacific via Hong Kong, but these add several hours and seldom beat the non-stops for a direct Seoul trip.
The distance is about 4,650 km. The non-stop runs roughly 6 hours 45 minutes on the 787. Departures are timed so that, on Korean Air especially, you can connect smoothly at Incheon to Japan, the US West Coast and Southeast Asia — making Seoul a viable stopover as well as a destination in its own right.
Seoul's marquee seasons drive fares: spring (April, cherry blossoms) and autumn (October, foliage) are the most popular and priciest, along with the Indian summer break. The cheaper, quieter windows are winter (December–February, cold but festive) and the monsoon shoulder of late June–August. We don't quote a fixed rupee fare — check live fares in the FlightGPT search for your dates.
With two non-stop carriers, compare Air India and Korean Air directly — service levels and price both vary. Book 8–12 weeks ahead for spring and autumn, less for the off-peak. Because Indians need a visa anyway, lock in dates once your visa is in hand to avoid fare creep. If you're flexible, winter travel is materially cheaper, and a one-stop on a Gulf or Southeast Asian carrier can occasionally undercut the non-stop in low season.
Non-stops depart Delhi T3 and arrive at Seoul Incheon International (ICN), consistently ranked among the world's best airports. Korean Air uses Terminal 2 at Incheon; most other carriers (including Air India and Asiana) use Terminal 1 — check yours, as the two are some distance apart. The AREX Express train reaches central Seoul in about 45 minutes, with frequent airport buses as an alternative.
Air India economy to Seoul typically allows around 25–30 kg checked + cabin depending on fare — see the Air India baggage guide. Korean Air economy on this route generally allows 1 piece up to 23 kg (more in premium cabins); confirm whether your fare uses the piece or weight system at booking, especially if connecting onward at Incheon. Request vegetarian or Jain meals in advance — Air India carries Indian meal options.
Indian passport holders are not eligible for South Korea's K-ETA and must obtain a visa before travel. For tourism this is the short-stay C-3-9 visa, applied for at a Korean embassy or authorised visa centre, usually allowing up to 30 days per entry. Processing typically takes around 10 working days, so apply early. From 2025, all visitors must also complete the online e-Arrival Card. Verify current requirements officially; our visa guide for Indian travellers covers the South Korea process.
If a non-stop doesn't suit, the best one-stop hubs are Singapore (SIN) on Singapore Airlines and Hong Kong (HKG) on Cathay Pacific, plus Gulf carriers via the Middle East. These add hours but can offer lower fares or better timings in the off-season. For most travellers, though, the daily Air India or Korean Air non-stop is the clear choice.
Buy a T-money card on arrival for Seoul's excellent metro and buses. Time a spring trip for cherry blossoms or autumn for foliage; both are spectacular but busy. Korea is very card-friendly, but carry some won for street food in Myeongdong and Gwangjang Market. Day-trip to the DMZ, and don't miss Gyeongbokgung Palace, Bukchon Hanok Village and the Han River parks.
Seoul fuses ancient palaces and hanok villages with neon-lit shopping, K-pop and a world-leading café and food culture. It's safe, ultra-connected and endlessly walkable, with mountains and the Han River woven through the city. Backed by daily non-stops from Delhi on two airlines, it's one of East Asia's most rewarding and accessible city breaks — just sort the visa early.
The non-stop takes about 6 hours 45 minutes on the Boeing 787, covering roughly 4,650 km. Both Air India and Korean Air operate the route directly into Seoul Incheon.
Air India and Korean Air each operate a daily non-stop (7x weekly) on the Boeing 787 Dreamliner. One-stop options run on Asiana, Singapore Airlines via Singapore and Cathay Pacific via Hong Kong.

Seoul is 3 hours 30 minutes ahead of Delhi. South Korea uses KST (UTC+9) and India uses IST (UTC+5:30). Neither observes daylight saving, so the gap stays the same all year.
The cheapest windows for Delhi (DEL) to Seoul Incheon (ICN) are typically January–February (after New Year) and July–August, when fares can dip to ≈₹35,000–₹50,000 return. Spring (late March–April, cherry blossom season) and autumn (October, foliage season) are peak demand periods where return fares frequently exceed ₹65,000–₹80,000. Air India, Korean Air, and Asiana Airlines all serve this route with one stop, and booking 6–8 weeks ahead in the off-peak months tends to yield the best prices.
Yes. Korean Air connects from Incheon to Japan, the US West Coast and Southeast Asia, so Seoul works well as a stopover. Just remember Indians still need a Korean visa even for a short stay outside the airport.
