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 use facilities such as the SilverKris Lounge (First Class), SilverKris Lounge (Business Class), or KrisFlyer Gold Lounge, depending on their eligibility.

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 a longer layover at Singapore Changi Airport, you can join one of the official transit city tours, which typically require at least around 5.5 to 6 hours of available transit time. These tours allow you to see highlights of Singapore without arranging your own transport. For shorter layovers, Changi Airport offers themed gardens, rest areas, and entertainment facilities to help you relax between flights. You can also enjoy a wide selection of dining and shopping right in the terminals. 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 UTC−8 in winter (approximately November to March) and UTC−7 in summer (approximately March to November). Bangkok follows Indochina Time, which is UTC+7 year-round. This means Bangkok is 15 hours ahead of San Francisco during Pacific Standard Time, and 14 hours ahead during Pacific Daylight Time.

Yes, your baggage will typically be checked through to Suvarnabhumi 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–Bangkok) 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 Bangkok 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–Bangkok 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.
