In-flight Dining
You will be served meals on both the Istanbul–Singapore and Singapore–Busan sectors, with menus designed to offer a balance of familiar favourites and regional flavours in Economy Class, Premium Economy Class, and Business Class.

Special Meals
We offer a range of special meals to meet medical or personal preferences on this route. You can request these in advance through our website or your booking agent, and they will be served on eligible sectors of your journey.

Book the Cook
Eligible Business Class passengers on the Istanbul–Singapore sector can pre-order from our Book the Cook service, selecting curated main courses before departure. This lets you personalise your dining experience on the long-haul part of your journey.

Beverage Service
Throughout the flight, you can enjoy a selection of hot and cold drinks, including juices, soft drinks, tea, and coffee. Our signature Singapore Sling is also available on board, offering a distinctive taste of our heritage during your journey.

For flights between Istanbul and Busan, our weight-concept baggage policy applies. In Economy Class, checked baggage allowances are 25kg for Lite and Value fares, and 30kg for Standard and Flexi fares. Premium Economy Class includes 35kg of checked baggage, and Business Class includes 40kg of checked baggage. Each checked bag must not exceed 32kg. For cabin baggage, Economy Class and Premium Economy Class customers may bring 1 piece up to 7kg, while Business Class customers may bring 2 pieces, each up to 7kg. Your final allowance will be 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 Istanbul to Busan once the aircraft is above 10,000 feet. It is free and unlimited for KrisFlyer members, although Economy Class and Premium Economy Class customers must add their membership number to the booking at least 1.5 hours before departure. Paid plans are available for non-members. The service is suitable for messaging, email, and basic browsing, but it does not support video streaming, video calls, or large file transfers.

On the Istanbul–Singapore sector operated by the Airbus A350-900, Economy Class offers a 32-inch pitch with up to 19-inch seat width, Premium Economy Class offers a 38-inch pitch with up to 20-inch seat width, and Business Class provides a fully flat bed with direct aisle access. On the Singapore–Busan sector operated by the Boeing 737-8 MAX, Economy Class offers similar ergonomic seating to our medium-haul fleet, while Business Class features a fully flat bed-style seat or deeply reclining seat with generous personal space and direct aisle access in a premium cabin layout.

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. Eligible customers may be able to use facilities such as the SilverKris Lounge (First Class), SilverKris Lounge (Business Class), or KrisFlyer Gold Lounge, depending on their cabin and status.

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 Istanbul but have a Business Class onward flight from Singapore, you get lounge access in Singapore only.

If you have a longer layover at Singapore Changi Airport, you can join the airport’s free transit tour programme, which typically requires a minimum layover of around 5.5 to 6 hours, subject to availability and entry requirements. This offers a convenient glimpse of the city without arranging your own transport. For shorter layovers, staying airside is very comfortable, with themed gardens, rest areas, entertainment zones, and in-terminal attractions to explore. Airport hotels and nap spaces allow you to rest and freshen up between flights. Your time at Singapore Changi Airport is more than just a wait — it's an integral part of your journey.

Istanbul follows Turkey Time (UTC+3) all year. Busan follows Korea Standard Time (UTC+9) all year. Busan is therefore 6 hours ahead of Istanbul throughout the year; for example, when it is 12.00 noon in Istanbul, it is 18.00 in Busan.

Yes, your baggage will typically be checked through to Gimhae International Airport in Busan when flying from Istanbul 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 (Istanbul–Singapore and Singapore–Busan) 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 Busan 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 Istanbul–Busan 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.
