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 customers may be invited to the SilverKris Lounge (First Class), SilverKris Lounge (Business Class), or KrisFlyer Gold Lounge, depending on their cabin and status.

At Singapore Changi Airport, longer layovers can include joining an official free city tour, which typically requires at least 5.5 to 6 hours between flights. This guided experience lets you see key highlights of Singapore before returning to the airport in time for your onward journey.

If you prefer to stay airside, Changi Airport offers themed gardens, quiet rest areas, play zones, and in some terminals, facilities such as cinemas and swimming pools. You can also make use of shower facilities and transit hotels for extra comfort.

Food courts, cafés, and retail outlets are spread across the terminals, so you can dine, shop, or simply relax between flights. 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) in winter and Pacific Daylight Time (UTC−7) from roughly March to early November. Hanoi stays on Indochina Time (UTC+7) all year. This means Hanoi is 15 hours ahead of San Francisco in winter, and 14 hours ahead during daylight saving time.

Yes, your baggage will typically be checked through to Noi Bai International Airport in Hanoi 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–Hanoi) 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 Hanoi 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–Hanoi 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.
