Most flights from Vietnam to San Francisco connect via Singapore Changi Airport, which offers gardens, art installations, rest areas, and a wide range of dining and shopping close to the gates. For shorter layovers, stay airside to enjoy the terminals, including playgrounds, TV lounges, and quiet zones. On longer daytime stops, you can consider a swim, a quick spa treatment, or exploring different terminals via the Skytrain to stretch your legs. Your time at the airport is more than just a wait — it is an integral part of your journey.

Ho Chi Minh City, Da Nang, and Hanoi all share the same time zone, Indochina Time (UTC+7), and do not observe daylight saving time. San Francisco follows Pacific Time, which is UTC−8 in standard time (roughly November to March) and UTC−7 during daylight saving time (roughly March to November). This means San Francisco is typically 14 or 15 hours behind Vietnam, depending on the time of year.

Yes, your baggage will typically be checked through to San Francisco when flying via the layover airport on a single booking with Singapore Airlines, provided both flight segments are under the same booking reference (PNR), the connection is under 24 hours, and, for partner operated onward flights, a through-check agreement is in place.

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.
