In-flight Dining
You will be served meals tailored to the time of day on both the Kathmandu–Singapore and Singapore–Surabaya sectors, with menus designed to offer a balance of regional and international flavours in Economy Class and Business Class.

Special Meals
We offer a variety of special meals on this route, which you can request in advance to meet your dietary needs or preferences. These should be ordered before your flight through our website or your booking agent so that we can prepare them for you.

Book the Cook
Eligible Business Class customers on selected sectors of this route can pre-order main courses from our Book the Cook service, choosing from an expanded menu created by our international culinary panel. This helps you personalise your dining experience before you board.

Beverage Service
Throughout the flight, a range of hot and cold drinks is available, including juices, soft drinks, tea, and coffee. Our signature Singapore Sling is also served on board, allowing you to enjoy a classic taste of Singapore in the air.

For Kathmandu to Surabaya flights, our weight concept applies. In Economy Class, checked baggage allowances are 25kg for Lite and Value fares, and 30kg for Standard and Flexi fares. In Business Class, the checked baggage allowance is 40kg. Each checked bag must not exceed 32kg.

For cabin baggage, Economy Class passengers may bring 1 piece up to 7kg, while Business Class passengers may bring 2 pieces, each up to 7kg. The final baggage allowance for your trip 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 on this route once the aircraft is above 10,000 feet. It is free and unlimited for KrisFlyer members; Economy Class members 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. Coverage and performance may vary slightly between the Boeing 737-8 MAX and Airbus A350-900 aircraft.

On the Kathmandu–Singapore sector operated by the Boeing 737-8 MAX, Economy Class seats typically offer a 32-inch pitch with up to 19-inch seat width, while Business Class features a fully flat bed with generous personal space.

On the Singapore–Surabaya sector operated by the Airbus A350-900, Economy Class also offers around a 32-inch pitch with up to 19-inch seat width, and Business Class provides a fully flat bed with direct aisle access for every seat, giving you space to rest and work.

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.

At Singapore Changi Airport, eligible customers may be able to access the SilverKris Lounge (First Class), SilverKris Lounge (Business Class), or KrisFlyer Gold Lounge, depending on their cabin class and membership 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 Kathmandu but have a Business Class onward flight from Singapore, you get lounge access in Singapore only.

Singapore Changi Airport is well known for its transit experience, with attractions such as indoor gardens, art installations, rest areas, and family-friendly zones across its terminals. If your layover is at least 5.5 hours, you may be able to join an official transit tour into the city, subject to availability and timing.

For shorter layovers, staying airside is comfortable, with options including quiet zones, nap areas, shower facilities, and a wide selection of dining and shopping. You can also explore themed zones and observation areas to watch aircraft movements.

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

Kathmandu operates on Nepal Time (UTC+5:45) all year round. Surabaya follows Western Indonesia Time (UTC+7:00) and does not observe daylight saving time. Surabaya is therefore 1 hour 15 minutes ahead of Kathmandu throughout the year, so remember to adjust your watch on arrival.

Yes, your baggage will typically be checked through to Juanda International Airport in Surabaya when flying from Kathmandu 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 (Kathmandu–Singapore and Singapore–Surabaya) 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 Surabaya 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 Kathmandu–Surabaya 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.
