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

At Singapore Changi Airport, longer layovers can be spent joining the free city tours, which typically require at least 5.5 to 6 hours of transit time. These guided trips let you see key highlights of Singapore without managing your own logistics. For shorter layovers, you can stay airside and enjoy themed gardens, rest zones, and entertainment, including play areas and viewing galleries. Some terminals also offer transit hotels and spa services if you prefer to sleep or freshen up. Your time at Singapore Changi Airport is more than just a wait — it is an integral part of your journey.

Hangzhou follows China Standard Time (UTC+8) all year. San Francisco follows Pacific Time, which is Pacific Standard Time (UTC−8) roughly from November to early March, and Pacific Daylight Time (UTC−7) from early March to early November. This means San Francisco is typically 16 hours behind Hangzhou in winter and 15 hours behind in summer.

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