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 San Francisco but have a Business Class onward flight from Singapore, you get lounge access in Singapore only. In Singapore (SIN), eligible passengers may be invited to use lounges such as the SilverKris Lounge (First Class), SilverKris Lounge (Business Class), or KrisFlyer Gold Lounge, depending on cabin and status.

Singapore Changi Airport is designed for comfortable and engaging layovers, with themed gardens, quiet rest areas, and a wide choice of dining and shopping. For longer transits, you can consider airport attractions such as viewing decks, indoor gardens, and, in some terminals, entertainment zones.

If your layover is at least 5.5 hours and you meet entry requirements, you may also have the option of joining an official transit tour that gives you a short introduction to the city before returning to continue your journey. For shorter layovers, staying airside lets you make the most of relaxation spaces, showers, and curated retail.

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

San Francisco follows Pacific Time, which is typically UTC-8 in winter and UTC-7 during daylight saving time (from roughly March to early November). Busan uses Korea Standard Time, which is UTC+9 all year. This means Busan is 17 hours ahead of San Francisco in winter, and 16 hours ahead during daylight saving time.

Yes, your baggage will typically be checked through to Gimhae International Airport when flying from San Francisco 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 (San Francisco–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 San Francisco–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.
