For flights between Surabaya and Busan, the weight-concept baggage policy applies. Checked baggage allowances are: Economy Class (Lite and Value fares: 25kg; Standard and Flexi fares: 30kg) and Business Class (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. Your final 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 on this route once the aircraft is above 10,000 feet. It is free and unlimited for KrisFlyer members, although 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 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 Surabaya–Singapore and Singapore–Busan sectors, Economy Class seats offer a 32-inch pitch with up to 19-inch seat width. Business Class provides a fully flat bed with direct aisle access, designed to give you ample personal space and comfort throughout your one-stop journey.

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 Surabaya but have a Business Class onward flight from Singapore, you get lounge access in Singapore only. Eligible passengers may use facilities such as the SilverKris Lounge (First Class), SilverKris Lounge (Business Class), or KrisFlyer Gold Lounge at Singapore (SIN).

At Singapore Changi Airport, longer layovers can be spent on a free official transit tour into the city, typically available if you have at least around 5.5 to 6 hours between flights and meet the programme conditions. For shorter connections, you can enjoy indoor gardens, rest areas, free movie screenings, and other airside facilities without leaving the terminal. Airport hotels and nap zones offer additional comfort if you prefer to rest between sectors. Your time at Singapore Changi Airport is more than just a wait — it is an integral part of your journey.

Surabaya follows the Asia/Jakarta time zone, which is UTC+7 and does not observe daylight saving time. Busan follows the Asia/Seoul time zone, which is UTC+9 and also does not observe daylight saving time. This means Busan is always 2 hours ahead of Surabaya throughout the year.

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