Busan's Gimhae International is busy, but you can't fly there directly from Kolkata. The cleanest routing is via Seoul-Incheon on Korean Air or Asiana, with a quick domestic-style hop down to Busan. Thai Airways via Bangkok and Singapore Airlines via Singapore are comfortable, often cheaper, alternatives. Cathay Pacific via Hong Kong is another option. With a reasonable layover the trip runs 11–15 hours. Note that some itineraries land at Seoul and continue by KTX high-speed train, which takes about 2.5 hours but can be cheaper.
A Seoul connection keeps you on a single Korean carrier with through-checked bags and the shortest final leg. A Bangkok or Singapore stop is comfortable and frequently the value pick, with a possible stopover thrown in. If you're flexible, compare flying into Kolkata to Seoul and taking the KTX to Busan against a through-fare — the train option sometimes saves ₹4,000–₹7,000 and lets you see the countryside. Avoid two-stop tickets unless the saving is significant.
Economy round-trips typically cost ₹45,000–₹72,000 depending on season, peaking in the summer beach months and around the October Busan International Film Festival. The cheapest stretches are March–May and September–November. Book 45–75 days ahead for the best fares. Business class often runs ₹1.9–3.2 lakh. Choosing a Bangkok or Singapore self-connection with a budget Korean carrier can occasionally undercut a through-fare by ₹6,000–₹10,000, though baggage isn't protected.
Indian passport holders need a South Korean visa in advance — there is no visa-on-arrival, and the K-ETA scheme does not currently cover Indian tourists for visa-free entry. Apply through the Korean Visa Application Centre with your passport, photos, itinerary, hotel bookings and financial proof. Processing typically takes 5–10 working days. Apply 3–5 weeks before departure. Holders of valid US, Schengen, Japan or other developed-country visas may qualify for streamlined entry — check current rules in our visa guide.
Gimhae International (PUS) is about 20 km west of central Busan. The Busan–Gimhae Light Rail Transit connects to the metro for the city centre, while limousine buses reach Haeundae and Seomyeon in roughly 45–60 minutes for around ₩7,000. Taxis to downtown cost about ₩20,000–28,000 and take 30–45 minutes. The airport is modern and easy to navigate, with arrivals processing usually under 40 minutes. A T-money transit card bought on arrival makes city travel seamless.
Busan has a humid subtropical climate moderated by the sea. The best months are May, June, September and October, with mild 18–26°C days. Summer (July–August) is hot, humid and busy with beachgoers at Haeundae, while winters are chilly at 3–10°C but rarely snowy. October brings the famous film festival and crisp autumn weather. Spring cherry blossoms in late March and April are spectacular. Pack a light jacket for sea breezes year-round.
Korean and Asian carriers usually allow 30 kg checked baggage on this route — confirm before flying. Korea is largely cashless; a T-money card and a tap card cover transport and convenience stores, though carry some won for small vendors. The 3.5-hour time difference is modest, so jet lag is mild. Download a translation and maps app, as English signage outside tourist zones can be limited. Keep your passport and visa accessible for hotel check-ins and any domestic transfers.
