Looking for cheap flights from Kolkata to Singapore? FlightGPT compares live CCU to SIN fares across every connected source — Indian carriers, Gulf hubs, OTAs and trusted travel agents — and shows the cheapest options side by side. Whether you want a Kolkata to Singapore non-stop tomorrow, a last-minute weekend deal or the lowest price three months out, every active Kolkata-Singapore fare is one search away.
Two carriers fly CCU–SIN nonstop: Singapore Airlines and IndiGo, with around two to three nonstop departures a day combined. Air India serves the city pair mainly via one-stop connections (typically through Delhi or another hub).
With nonstops at just over 4 hours, choose a direct flight unless an Air India one-stop is meaningfully cheaper or better timed for your onward plans.
The nonstop CCU–SIN flight time is about 4h 15m (roughly 4h 11m in the air), covering around 2,890 km. Because Kolkata is India's easternmost major metro, this is one of the shortest India–Singapore nonstops. The route runs southeast across the Bay of Bengal toward Changi. Singapore is 2.5 hours ahead of India, so factor the time change into arrival planning and any onward connections.
CCU–SIN fares are usually lowest in the Southeast Asia low season — roughly May, June and September. Prices peak over the December–January holidays, around the September Grand Prix, and during Durga Puja travel when demand from West Bengal surges in both directions.
Booking about 3–8 weeks ahead generally lands the best nonstop fares. With only two nonstop carriers, fares can firm up quickly, so book when you see a good price. Compare live fares in the FlightGPT search rather than assuming a fixed rate.

Kolkata (CCU): international flights, including CCU–SIN, depart from the integrated terminal at Netaji Subhas Chandra Bose International Airport, which handles both domestic and international operations under one roof — convenient for connections.
Singapore (SIN): Singapore Airlines and IndiGo typically use Terminal 2 at Changi; confirm on your boarding pass as codeshares can vary. Changi's free Skytrain links all terminals, and e-gates speed entry for eligible passengers.
Singapore Airlines includes a generous checked allowance (typically 25–30 kg in economy by fare) plus cabin baggage. IndiGo includes cabin baggage but charges for checked bags, so add the allowance during booking — see the IndiGo baggage guide for current limits. If you take an Air India one-stop, baggage is included; see the Air India baggage page. Weigh bags beforehand to avoid steep international excess fees.
Indian passport holders must obtain a Singapore e-Visa before travel — there is no visa-on-arrival. Apply through an authorised visa agent (no walk-ins). From 1 January 2026 the fee is around INR 2,100 plus an agent service charge, with processing typically 3–5 working days and a usual stay of up to 30 days on a single entry. Carry a passport valid for six months, confirmed return tickets and hotel bookings. Verify the current requirements on the official ICA Singapore portal.
Singapore offers Gardens by the Bay, the Marina Bay Sands skyline, Sentosa's beaches and Universal Studios, and some of Asia's finest food — including Little India's familiar flavours for Kolkata travellers. Safe, clean, English-speaking and superbly organised, it's perfect for families and first-time international visitors, and a natural springboard to Bintan, Batam, Bali and the wider region. For eastern India, it's the closest world-class Asian metropolis by air.
