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 entitlement.

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

If you have enough time, Singapore Changi Airport offers a complimentary city tour for transit passengers with a layover of around 5.5 hours or more, subject to eligibility and timing, giving you a snapshot of the city between flights. For shorter layovers, you can stay airside and enjoy themed gardens, relaxation zones, and quiet seating areas.

The airport also features playgrounds, rest areas, and in selected terminals even attractions such as indoor greenery and water features, making it easy to stretch your legs and reset before your onward journey. Airport hotels and nap facilities are available if you prefer to rest and freshen up.

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

San Francisco follows Pacific Time, which is UTC−8 in winter and UTC−7 during daylight saving time, typically from March to early November.

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 San Francisco–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.
