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 enjoy facilities such as the SilverKris Lounge (First Class), SilverKris Lounge (Business Class), and the KrisFlyer Gold Lounge.

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

Singapore Changi Airport is designed for comfortable and engaging layovers, with themed gardens, quiet zones, rest areas, and a wide choice of dining and shopping. With a longer connection, you may be able to join an official transit tour into the city, which usually requires several hours between flights. For shorter layovers, you can stay airside, enjoy facilities such as movie zones, children’s play areas, and walking trails, or simply relax and freshen up before your next flight. Your time at Singapore Changi Airport is more than just a wait — it is an integral part of your journey.

Kuala Lumpur follows Malaysia Time (UTC+8) all year and does not observe daylight saving time. Surabaya follows Western Indonesia Time (UTC+7), also without daylight saving. This means Surabaya is 1 hour behind Kuala Lumpur throughout the year.

Yes, your baggage will typically be checked through to Surabaya when flying from Kuala Lumpur 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 (Kuala Lumpur–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 Kuala Lumpur–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.
