There is no non-stop flight between Patna and Seoul, so every itinerary needs at least one change. The most efficient routings go via Delhi, which has direct Korean Air and Air India flights to Incheon, or via Kolkata and an Asian hub such as Singapore. PAT–Delhi is about 1h 50m and Delhi–Seoul runs roughly 6h 30m, so with a layover the total is around 12–14 hours. Routing via Kolkata is a natural choice given Patna's strong CCU links.
From Patna your first leg is usually on IndiGo, Air India or Akasa to the hub. The hub–Seoul sector is flown by major carriers.
A single ticket through Delhi on Air India or Korean Air is usually the simplest, with through-checked bags and protected connections into Incheon.
Economy round-trips on this routing typically range from ₹52,000 to ₹88,000 depending on season, hub and lead time. Fares are lowest in February, June and November, while spring blossom in April and the autumn-foliage peak in October sit at the top of the band. Booking 8–10 weeks ahead usually wins the best price. It can pay to compare a Kolkata to Seoul departure, since Kolkata often has stronger eastward connections than Patna.
Full-service carriers such as Korean Air, Asiana, Air India, Singapore Airlines and Cathay Pacific generally include 23–30 kg checked allowance in economy, with Korean and Asiana often allowing a generous two-piece allowance to ICN. On a through-ticket your bags travel all the way to Seoul; on two separate tickets you collect and re-check at the hub, so leave at least 4 hours. Cabin baggage is usually limited to about 10 kg on these carriers.
You land at Incheon International Airport (ICN), about 50 km west of central Seoul and regularly ranked among the world's best. The AREX express train reaches Seoul Station in roughly 50 minutes for around ₩9,500, while the cheaper all-stop line costs about ₩4,500. Airport limousine buses and taxis also serve the city. Buy a T-money card on arrival to ride Seoul's metro and buses smoothly, and use the free airport Wi-Fi to set up navigation.
South Korea's appeal has surged with the global wave of K-pop, K-dramas and Korean cuisine. Seoul offers historic palaces such as Gyeongbokgung, the shopping and nightlife of Myeongdong and Hongdae, and easy day trips to the DMZ and Nami Island. As a hub for electronics, shipbuilding and IT, it also draws Indian professionals on assignment. The city is safe, efficient and very well connected, ideal for first-time visitors from Bihar.
Indian passport holders need a visa to visit South Korea — there is no general visa-on-arrival. Apply for a short-term tourist (C-3) visa at the Korean visa application centre, which typically takes about 5–10 working days and needs an itinerary, bank statements and confirmed bookings. Korea's K-ETA travel authorisation applies in some cases when reinstated, so check the latest position in our visa guide before booking.
