IndiGo operates from Kolkata to Bangkok's Suvarnabhumi Airport (BKK), from where Thai Airways and Seoul-based carriers like Korean Air and Asiana Airlines connect to Incheon (ICN). Singapore Airlines connects through Changi Airport (SIN) — one of the world's best transit airports — and offers particularly comfortable connections with strong on-time performance. Cathay Pacific routes via Hong Kong (HKG) and is a popular option with competitive fares from eastern India. Air India does not currently operate a Kolkata–Seoul route directly but sometimes appears in multi-city searches through Delhi or Mumbai. Korean Air and Asiana Airlines — South Korea's two major full-service carriers — may appear on codeshares from connecting points. Chinese carriers such as Air China or China Eastern offer lower-cost connections via Beijing or Shanghai, though route viability can vary with India–China relations.
The great-circle distance between Netaji Subhas Chandra Bose International (CCU) and Incheon International Airport (ICN) is ≈ 4,590 km. Via Bangkok, the CCU–BKK sector takes ≈ 2.5 hours and BKK–ICN ≈ 5 hours, giving a total of ≈ 8–10 hours including a 1–2 hour layover. Via Singapore (SIN), the routing is slightly longer in distance but Changi's efficiency and Singapore Airlines' strong connections make it a preferred option; total time is ≈ 9–11 hours. Via Hong Kong, the HKG–ICN sector is only ≈ 3 hours, and the CCU–HKG sector ≈ 4 hours, giving a total of ≈ 8–10 hours. Seoul (Korean Standard Time, KST) is 3h 30m ahead of IST — a relatively mild adjustment that most travellers handle within a day or two.
As of 2026, Indian passport holders typically need either a South Korea tourist visa or the K-ETA (Korea Electronic Travel Authorisation) depending on current bilateral policy. The K-ETA (applied at k-eta.go.kr) is a pre-authorisation costing KRW 10,000 (≈ ₹650) and is valid for 2 years / multiple entries. However, K-ETA eligibility for Indian citizens has been subject to policy changes — check the current status on the official Korean immigration portal before applying. If K-ETA is not available for Indian passports, a tourist visa (C-3 category) must be applied for in person at the South Korean embassy or via VFS Global in India. Processing typically takes 5–10 working days. See /visas for the current ruling on Indian K-ETA eligibility and visa procedures.
Demand on the Kolkata–Seoul route peaks around three periods: March–April (South Korea's cherry blossom season, hugely popular with Indian tourists), July–August (summer holiday season), and October–November (autumn foliage, popular with travellers from Kolkata). The cheapest windows are typically January–early February and late June (before full summer pricing kicks in). Economy round-trip fares generally start from ≈ ₹25,000–38,000 in the off-peak window. Cherry blossom season (late March) and autumn (October) can push fares to ₹55,000–75,000. Booking 8–10 weeks ahead is advisable. Singapore Airlines via Changi and IndiGo–Thai Airways codeshare combinations are frequently the most competitive options.
Singapore Airlines economy class typically allows 23–30 kg of checked baggage (fare-class dependent), with one of the best in-class service reputations in the industry. Thai Airways allows 20–30 kg, while Cathay Pacific offers 23–30 kg. IndiGo (on the Kolkata–Bangkok sector if booked separately as a budget option) includes 15–20 kg in most economy fares. Korean Air and Asiana Airlines, when connecting from the hub, typically allow 23 kg in economy. Korean Air has a particularly good reputation for generously portioned in-flight Korean meal options; requesting a vegetarian or Indian meal in advance is possible on full-service carriers. Cabin luggage is 7–12 kg depending on the carrier.
Incheon International Airport (ICN) is consistently ranked among the world's top airports for efficiency, cleanliness, and facilities. It sits on an island ≈ 50 km west of Seoul city centre. The airport has two terminals (T1 and T2); most international carriers use T1, while Korean Air and Delta use T2 — free automated people-movers connect them in ≈ 5–7 minutes. The Airport Express (AREX) connects Incheon to Seoul Station in ≈ 43 minutes (express) or ≈ 60 minutes (all-stop), and runs every 5–10 minutes. Tickets cost ≈ KRW 9,000 (≈ ₹575) for the express. Taxis to central Seoul take 50–70 minutes and cost ≈ KRW 60,000–80,000. A multi-day transit in Seoul without leaving international transit areas is technically possible for some nationalities but not recommended — the city is worth exploring.
Seoul is a fascinating blend of ancient palaces, futuristic architecture, and vibrant street culture. Gyeongbokgung Palace and the adjacent Bukchon Hanok Village offer a glimpse of Korea's Joseon dynasty past. Myeongdong and Hongdae are the go-to shopping and nightlife districts. Korean cuisine is a highlight — try samgyeopsal (grilled pork belly), bibimbap, and Korean fried chicken, all widely available at affordable prices. K-pop enthusiasts can visit the HYBE Insight museum or join BTS-themed city tours. The city has over a dozen Michelin-starred restaurants as well as outstanding street food. The Indian diaspora in Seoul is small but growing; halal restaurants and Indian-friendly dining options are available in the Itaewon district, Seoul's multicultural hub.
South Korea uses the Korean Won (KRW); T-money transit cards (topped up at airport convenience stores) are essential for using the metro, buses, and even some taxis in Seoul. Mobile data is cheap and widely available — a visitor SIM or portable Wi-Fi router from the airport counters costs ≈ KRW 8,000–20,000 for a week. Google Maps works well in Korea for most navigation; Naver Maps is preferred by locals for more accurate transit directions. The Kolkata-to-Seoul time shift of 3h 30m ahead means east-facing morning room allocations help adjust body clocks faster. South Korea has excellent universal healthcare, and pharmacies are found on almost every city block. Carry a copy of your visa/K-ETA approval on your phone throughout your stay.
