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), and KrisFlyer Gold Lounge during their transit.

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.

Singapore Changi Airport is well suited to both short and longer layovers. For longer transit times of around 5.5 hours or more, you can consider official transit tour options into the city, allowing you to see highlights before returning to the airport. For shorter layovers, stay airside and enjoy themed gardens, rest zones, play areas, and a wide choice of dining. Some terminals also offer pay-per-use lounges, spa services, and transit hotels if you would like to rest in private. 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). Hangzhou follows China Standard Time, which is UTC+8 year-round. This means Hangzhou is typically 16 hours ahead of San Francisco in winter and 15 hours ahead in summer.

Yes, your baggage will typically be checked through to Hangzhou Xiaoshan 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–Hangzhou) 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 Hangzhou 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–Hangzhou 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.
