The table below summarizes key operational parameters for the SIN-CCU route based on verified schedule data.

How far is Singapore from Kolkata by flight?

The air distance between Singapore Changi Airport (SIN) and Kolkata Netaji Subhas Chandra Bose International Airport (CCU) covers approximately 1,803 miles, placing the two cities on roughly the same latitude band in South Asia. According to Flights.com, this puts the great-circle route well within range for non-stop service on narrow-body aircraft.

Passengers should note that Kolkata sits 2 hours 30 minutes behind Singapore in local time. That means a morning departure from Changi arrives in Kolkata before noon by local clock, even though the flight itself takes just over four hours.

Air distance details

The 1,803-mile figure represents the shortest possible route between the two airports, though actual flight paths may vary slightly based on wind patterns, air traffic control routing, and seasonal jet stream conditions. Most aggregators round this to “about 1,800–1,813 miles” when displaying route information.

Flight path overview

Flying from SIN to CCU puts aircraft over the Bay of Bengal for most of the journey. No overland routing is involved, which simplifies customs and immigration procedures at both endpoints. The route essentially tracks northwest from Singapore, cutting across the Andaman Sea before crossing into Indian airspace near West Bengal.

What this means: The direct route is clean and typically free of significant congestion delays. Airlines running this corridor report average in-flight times between 4 hours 5 minutes and 4 hours 20 minutes depending on aircraft type and prevailing winds.

Does Singapore Airlines go to Kolkata?

Yes. Singapore Airlines (SQ) operates direct flights to Kolkata, making it one of two carriers currently serving the SIN-CCU non-stop corridor alongside IndiGo. The flag carrier’s presence on this route signals its importance for business travel and connecting traffic through Changi’s global hub.

According to FlyTeam (a flight schedule aggregator), Singapore Airlines flight SQ516 departs Singapore Changi at 20:40 and lands in Kolkata at 22:15, using aircraft such as the 737-8 MAX or A350-900 depending on the day. The flight operates on specific days—typically Tuesdays, Thursdays, and Fridays during September 2025.

Singapore Airlines routes to CCU

At present, SQ offers one daily or near-daily frequency depending on the season, positioning Kolkata within its broader South Asia network that includes Delhi, Mumbai, Chennai, and Bangalore. For passengers connecting through Changi, SQ’s schedule makes same-day connections from Europe, Australia, and Southeast Asia relatively smooth.

Fare from SGD 349

Fares on Singapore Airlines for this route start from approximately SGD 349 for a one-way economy ticket, based on aggregator listings and the carrier’s own booking platform. Premium cabin options push significantly higher, with business class fares typically running several times the economy rate. The Google Flights interface shows Singapore Airlines nonstop fares ranging roughly from ₹43,500 to ₹85,000 depending on booking timing and class.

The implication: Singapore Airlines targets the premium leisure and business segment on this route. If budget sensitivity is high, IndiGo typically undercuts SQ substantially on base fares, though service differences and baggage policies warrant comparison before booking.

What is the Singapore to Kolkata flight time?

The standard flight time from Singapore to Kolkata ranges between 4 hours 5 minutes and 4 hours 20 minutes for non-stop service. FlightsFrom cites 4 hours 15 minutes as the typical duration, with slight variations based on aircraft and weather conditions.

Typical duration

IndiGo flight 6E1016 consistently operates in the 4h15m range, departing SIN at 10:30 and arriving CCU at 12:15. This schedule works well for morning departures from Singapore that align with daytime arrival in Kolkata—useful for business travelers who need to conduct meetings the same afternoon.

Singapore Airlines SQ516 runs slightly faster at 4h5m, likely due to favorable tailwinds on the evening departure and newer aircraft on some rotations. The A350-900 variant on certain days contributes to the faster block time.

Factors affecting time

Several variables can push actual flight times outside the 4h5m–4h20m window. Seasonal jet stream variations extend or compress westbound flights by 10–20 minutes. Air traffic control congestion at either airport occasionally adds holding time before landing. Meteorological conditions in Kolkata during monsoon season (June–September) sometimes require diversion or delay, though this affects arrival more than block time.

What this means: The 4-hour window is reliable, but passengers should build buffer time into tight connections, especially during the June–September weather window when Kolkata sees heavy rainfall and occasional visibility issues.

What is the Singapore to Kolkata flight ticket price?

Fare data from major booking platforms shows significant variation depending on carrier, booking window, and travel date. The cheapest verified one-way fares start around INR 10,599 on MakeMyTrip for IndiGo service, while Singapore Airlines economy starts from approximately SGD 349 (roughly ₹21,000 equivalent) on the carrier’s own platform.

According to Cheapflights, IndiGo one-way fares can drop to S$155 with return fares around S$329 during off-peak periods. March appears to be the cheapest month historically, while December sees the highest average pricing at S$431 across all airlines.

Cheapest options

• IndiGo via MakeMyTrip: INR 10,599 one-way
• IndiGo via Cheapflights: S$155 one-way (seasonal)
• IndiGo via Skyscanner: from $116 one-way
• Singapore Airlines: from SGD 349 one-way

Airline price comparison

Breaking down by carrier:

The comparison below highlights key differences between the two main carriers operating this route, from pricing to service inclusions.

The catch: Aggregator prices fluctuate rapidly, and the “from” fares rarely appear for weekend or holiday travel. Budget-minded travelers should set price alerts and book 3–6 weeks ahead for the best odds against sudden spikes.

What airlines fly Singapore to Kolkata route?

Two airlines currently operate direct non-stop flights on the SIN-CCU route: IndiGo and Singapore Airlines. According to FlyTeam’s flight schedule database, these carriers together provide 12–14 weekly non-stop departures between Singapore Changi and Kolkata.

Skyscanner’s route data notes that IndiGo is the most popular choice among travelers on this corridor, while Singapore Airlines leads in on-time performance metrics.

IndiGo details

IndiGo’s 6E1016 operates daily, departing Singapore at 10:30 and arriving Kolkata at 12:15. The flight uses an A320neo, a fuel-efficient narrow-body well-suited to the 4h15m sector. According to KAYAK’s performance data, IndiGo maintains a 93% on-time record on this route—one of the better showings among carriers serving the India-Southeast Asia corridor.

IndiGo flies the route approximately 7 times per week, per Momondo’s aggregation of airline schedules.

Other operators

Air India appears on some aggregator listings with connecting service, though non-stop options are limited to the two carriers above. Other aggregators show 5 total operators when including one-stop combinations via hubs like Dubai or Bangkok, but these add significant travel time and are rarely price-competitive with the direct options.

Direct vs connecting

Non-stop flights save 2–4 hours compared to connecting options through Middle Eastern hubs. For passengers prioritizing time over cost, the direct carriers represent the clear choice. Connecting flights may occasionally undercut direct fares during sales periods, but the time penalty typically outweighs the savings for most business and leisure travelers.

The pattern: For this 1,800-mile route, the economics clearly favor narrow-body non-stop operations. Both IndiGo and Singapore Airlines have structured their schedules to serve the dominant same-day travel pattern between the two cities.

How to book Singapore to Kolkata flights: Step by step

Booking a direct flight from Singapore to Kolkata involves comparing aggregator prices, checking airline sites for the latest schedules, and understanding baggage implications before committing to a fare.

Step 1: Compare aggregator prices

Start with a meta-search engine like Skyscanner or KAYAK to get a sense of the price range across carriers. Note the “from” prices often represent off-peak availability—check specific dates rather than running generic searches.

Step 2: Verify schedules on airline sites

Direct booking on IndiGo or Singapore Airlines ensures access to the most current schedule information. According to FlyTeam, schedules as of September 2025 may change, so confirming with the carrier within 72 hours of departure remains advisable.

Step 3: Check baggage policies

IndiGo’s base economy fare typically includes only a personal item and a cabin bag. A checked bag (23 kg) adds approximately INR 500–1,500 depending on the booking channel. Singapore Airlines’ economy fare generally includes one checked bag up to 23 kg for no additional charge—a meaningful difference when packing for a week-long trip.

Step 4: Book and confirm

After comparing final prices including fees and baggage, proceed with booking. Save the confirmation email and itinerary number. For Singapore Airlines, download the mobile boarding pass 24 hours before departure. For IndiGo, check-in opens 48 hours prior on the carrier’s app or website.

Step 5: Arrive prepared for international departure

Singapore Changi Terminal 2 handles most India-bound departures. Allow 2 hours for the check-in and security process, particularly during peak evening hours when SQ516 departs. Kolkata’s immigration processing for arriving international passengers can take 20–45 minutes depending on queue volume.

What this means: Booking the SIN-CCU route has become relatively straightforward, but travelers who skip the baggage policy check frequently overpay by 15–25% when adding luggage to IndiGo’s base fare. The time spent comparing final prices—including ancillary costs—typically saves INR 1,000–3,000 versus booking the cheapest-looking headline price without checking what it actually includes.

What travelers say about SIN-CCU flights

Several travel platforms and aggregators have compiled traveler feedback on the Singapore-Kolkata route, offering practical insights beyond schedule and price data.

“IndiGo is the airline most travelers choose for flights from SIN to CCU. Among carriers operating on this route, Singapore Airlines leads the way for on-time arrivals.”

— Skyscanner (travel search engine)

“Schedules may change without notice, so please check with airlines before booking.”

— FlyTeam (flight schedule provider)

“25% of KAYAK users found one-way fares at or below $212, with round-trip fares at or below $264 on this route.”

— KAYAK (flight search platform)

The pattern: Traveler feedback consistently highlights the on-time reliability difference between carriers, with IndiGo winning on popularity but Singapore Airlines earning higher marks for punctuality. The schedule volatility warning from FlyTeam reflects the reality that Indian carriers and Singaporean operators both adjust frequencies based on load factor and operational constraints.

Travelers on Singapore to Kolkata routes may note that London to Singapore flight times span 13-14 hours, served by major carriers with daily options.
