Looking for cheap flights from Kolkata to Surabaya? FlightGPT compares live CCU to SUB fares across every connected source — Indian carriers, Gulf hubs, OTAs and trusted travel agents — and shows the cheapest options side by side.

Surabaya connects via Kuala Lumpur or Singapore. The common path is Kolkata–KL (about 4h 15m) on AirAsia or Batik Air, then a 3h KUL–Surabaya leg; or via Singapore on Scoot/Singapore Airlines with a similar SIN–SUB hop. With a tidy 2–3 hour layover, total time is around 10–12 hours; weaker or overnight connections push it to 15–18. AirAsia through-fares are usually cheapest, while Singapore offers more comfort on a longer itinerary.
Indian passport holders can use Indonesia's visa-on-arrival or pre-bought e-VoA, valid 30 days and extendable once for a further 30. The fee is about IDR 500,000 (around US$35 / ₹2,900). Carry a passport valid 6+ months, onward tickets and proof of funds. Juanda is a VoA-eligible airport. Buying the e-VoA online before you fly trims the arrival queue. Full details are in our visa guide.
Return economy fares typically run ₹32,000–₹60,000. Low-cost combinations via KL anchor the budget end, often ₹8,000–₹15,000 below full-service. The cheapest months are February–March and November; the June–August peak and December–January holidays lift prices. Booking 6–10 weeks ahead and catching AirAsia or Scoot sales can save another ₹4,000–₹8,000. Account for baggage add-ons on the budget legs.
Juanda International (SUB) is about 20 km south of central Surabaya. A Grab or airport taxi into town costs roughly IDR 100,000–180,000 (₹600–₹1,100) and takes 30–50 minutes. For Mount Bromo, it's a 3–4 hour drive south-east to Cemoro Lawang; for Ijen, about 5–6 hours toward Banyuwangi. Many travellers book a 2–3 day Bromo–Ijen tour from Surabaya. Pick up a Telkomsel or XL SIM in arrivals for a few GB.
The headline experiences are Mount Bromo's sunrise over a sea of caldera sand and the surreal blue flames and turquoise crater lake of Kawah Ijen, best seen pre-dawn. Add Madakaripura waterfall and, for the adventurous, an overland route on to Bali via the Ketapang–Gilimanuk ferry (about 1 hour crossing). A 6–8 day trip covers the volcanoes well. Daily budgets of ₹2,800–₹5,500 stretch comfortably across East Java.
East Java is tropical but the volcanic highlands are cool — Bromo's rim can drop near 3–8°C at dawn, so pack a warm layer even though the lowlands sit at 28–33°C. The dry season from May to October gives the clearest sunrises and safest crater visits; November–April brings more cloud and rain that can hide Bromo entirely. Surabaya is only 1h 30m ahead of India, so jet lag is minimal on arrival.
The rupiah is the currency; cards work in Surabaya, but carry IDR 1–2 million cash for Bromo and Ijen where ATMs are scarce. Volcano tours include 4x4 jeeps and guides — book a reputable operator and confirm what's included. Grab and Gojek cover city rides and food cheaply. Bring a headlamp and sturdy shoes for the pre-dawn climbs. For a Sumatra alternative, compare our Kolkata–Medan guide.
