Flights from Kolkata (CCU) to Istanbul (IST)

In-flight Dining
You will be served meals on both the Kolkata–Singapore and Singapore–Istanbul sectors, with menus designed to suit the length and timing of each flight and complimentary meals in all cabins.

Special Meals
We offer a range of special meals for specific dietary needs on this route. These should be requested in advance through your booking so that we can load them for both flight sectors.

Eligible passengers in premium cabins can take advantage of our Book the Cook service on selected sectors, choosing from a wider menu of main courses prepared specially for their flight.

Beverage Service
A selection of hot and cold drinks is served throughout the journey, including juices, soft drinks, and hot beverages. Our signature Singapore Sling is also available on board.

For Kolkata–Istanbul journeys, the weight concept applies. Checked baggage: Economy Class passengers may check 25kg on Lite/Value fares and 30kg on Standard/Flexi fares. Premium Economy Class passengers may check 35kg. Business Class passengers may check 40kg. Each checked bag must not exceed 32kg. Cabin baggage: Economy Class and Premium Economy Class may bring 1 piece up to 7kg, while Business Class may bring 2 pieces, each up to 7kg. Your exact allowance is shown on your e-ticket, and KrisFlyer Elite Gold and PPS Club members enjoy additional allowances.

Wi-Fi is available on Singapore Airlines flights from Kolkata to Istanbul once the aircraft is above 10,000 feet. It is free and unlimited for KrisFlyer members; Economy Class and Premium Economy Class members should add their membership number to the booking at least 1.5 hours before departure. Paid plans are available for non-members. The connection is suitable for messaging, email, and basic browsing, but it does not support video streaming, video calls, or large file transfers.

On both the Kolkata–Singapore and Singapore–Istanbul sectors, Economy Class offers a seat pitch of about 32 inches with up to 19 inches of seat width, providing comfortable space for the journey. Business Class on the Airbus A350-900 features a fully flat bed with direct aisle access from every seat. On the Singapore–Istanbul sector, Premium Economy Class provides a seat pitch of about 38 inches and up to 20 inches of seat width for added comfort.

Yes, Singapore Airlines provides lounge access to eligible passengers with a layover in Singapore. Your eligibility is based on your class of travel or your KrisFlyer and Star Alliance status, and it is determined by your flight leaving Singapore. Other options, like purchasing a day pass at a pay-per-use lounge, are also available.

Lounge Access Eligibility
Cabin Class: Complimentary for Suites, First, and Business Class passengers. Premium Economy and Economy travellers do not have access unless they hold eligible status.

Frequent Flyer Status: PPS Club and KrisFlyer Elite Gold (or Star Alliance Gold) members have access regardless of cabin class.

The 'Next Segment' Rule: Eligibility is based on the flight immediately departing that airport. For example, if you fly Economy from Kolkata but have a Business Class onward flight from Singapore, you get lounge access in Singapore only.

With a layover at Singapore Changi Airport, you can enjoy one of the world’s most comfortable transit hubs. If you have at least 5.5 to 6 hours between flights and meet the eligibility criteria, you may join an official transit tour to see highlights of the city. For shorter layovers, stay airside and explore themed gardens, art installations, rest areas, and children’s play zones.

You will also find a wide choice of dining options, quiet seating areas, and, in some terminals, facilities such as showers and transit hotels for extra rest. Clear wayfinding and efficient security help you move smoothly between gates, so you can make the most of your time before boarding.

Your time at Singapore Changi Airport is more than just a wait — it is an integral part of your journey.

Kolkata follows India Standard Time (IST), which is UTC+5:30 and does not observe daylight saving time. Istanbul follows Türkiye Time (TRT), which is typically UTC+3 year-round. This means Istanbul is 2.5 hours behind Kolkata throughout the year.

Yes, your baggage will typically be checked through to Istanbul Airport when flying from Kolkata via Singapore on a single booking with Singapore Airlines.

Through-Check Conditions
For your bags to be sent directly to your final destination, the following general conditions must be met:

Single Itinerary: Both flight segments (Kolkata–Singapore and Singapore–Istanbul) must be under the same booking reference or PNR.

Layover Duration: Your connection in Singapore must be less than 24 hours. If your layover exceeds 24 hours, it is considered a stopover, and you will typically be required to collect your luggage and re-check it for your onward flight.

Partner Airlines: If your onward flight from Singapore to Istanbul is operated by a partner airline, Singapore Airlines has through-check agreements that usually allow your bags to be tagged to your final destination.

You may be able to plan a stopover in Singapore on your Kolkata–Istanbul trip, subject to your ticket conditions and availability. When booking, you can search for multi-city options or speak with our customer service team or your travel agent, who can advise whether a stopover can be added to your itinerary.
