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 facilities such as the SilverKris Lounge (First Class), SilverKris Lounge (Business Class), or KrisFlyer Gold Lounge, depending on cabin and status.

Singapore Changi Airport offers extensive facilities that make layovers comfortable and engaging. With a sufficiently long connection, you can join one of the airport's official free tours into the city, which usually require a layover of at least 5.5 to 6 hours, allowing time for immigration and boarding procedures.

If you prefer to stay airside, you can explore landscaped gardens, quiet rest areas, and entertainment zones, or simply relax at one of the many cafes and restaurants across the terminals. Transit hotels and nap-friendly spaces also help you freshen up between long-haul and regional flights.

For shorter layovers, spending time near your departure gate while enjoying the airport's amenities ensures a smooth connection to your Phnom Penh flight. 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 (UTC−8), switching to Pacific Daylight Time (UTC−7) roughly from March to early November. Phnom Penh follows Indochina Time (UTC+7) year-round and does not observe daylight saving. This means Phnom Penh is typically 15 hours ahead of San Francisco in winter, and 14 hours ahead in summer.

Yes, your baggage will typically be checked through to Phnom Penh 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–Phnom Penh) 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 Phnom Penh 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–Phnom Penh 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.
