Flights from San Francisco (SFO) to Vietnam

Yes, meals are served on all Singapore Airlines flights between San Francisco and Vietnam. On the long-haul San Francisco to Singapore sector, you can enjoy our in-flight dining, which offers curated menus designed to suit different tastes and times of day, with complimentary meals and snacks in all cabins. Special meals are available on request before departure to accommodate various dietary needs. On eligible flights in premium cabins, you may also be able to use our Book the Cook service to pre-select main courses crafted by our international culinary panel. A full beverage service, including wines, spirits, beers, juices, soft drinks, and our signature Singapore Sling, is available, with a more streamlined but still complimentary offering on the regional Singapore to Vietnam sectors.

Flights between the United States and Vietnam operate under our piece concept for checked baggage. In Economy Class, you can typically check in at least one or two pieces, each within a set weight limit. Premium Economy Class generally allows at least two pieces, each with a higher weight limit than Economy Class. Business Class usually allows at least two pieces at an even higher weight per piece. Cabin baggage allowances also vary by cabin, with an additional piece and higher combined weight permitted in premium cabins. For full details and any updates, please refer to your ticket and our baggage policy before you travel.

Wi-Fi is available on most Singapore Airlines flights from San Francisco to Vietnam once the aircraft is above 10,000 feet. KrisFlyer members enjoy free and unlimited Wi-Fi; if you are travelling in Economy Class or Premium Economy Class, simply ensure your membership number is added to your booking at least 1.5 hours before departure. Non-members and additional users can purchase access plans on board. The connection is suitable for messaging, email, and basic browsing, but it does not support video streaming, video calls, or large file transfers.

Across the routes from San Francisco to Vietnam, you can travel in Business Class, Premium Economy Class, or Economy Class. On the San Francisco to Singapore long-haul sector, all three cabins are generally available, depending on the specific flight. On the regional Singapore to Vietnam sectors, services to Ho Chi Minh City and Hanoi offer Business Class and Economy Class on the Airbus A350-900, while flights to Da Nang on the Boeing 737-8 MAX provide Business Class and Economy Class without a separate Premium Economy Class cabin.

In Economy Class, you can expect around a 32-inch seat pitch with up to 19-inch seat width, depending on aircraft and configuration. Premium Economy Class on eligible long-haul sectors offers around a 38-inch seat pitch with up to 20-inch seat width, providing more personal space and a wider seat. In Business Class on both the Airbus A350-900 and Boeing 737-8 MAX, your seat converts into a fully flat bed, with direct aisle access on the long-haul A350-900 and a spacious recliner or flat-style experience on the regional aircraft, subject to configuration. Cabin layouts can differ slightly between routes and aircraft types.

Yes, Singapore Airlines provides lounge access to eligible passengers at layover airports on connections to Vietnam.

Other options such as purchasing a day pass are also available.

Most journeys from San Francisco to Vietnam connect at Singapore Changi Airport, which is well suited to both short and longer layovers. For shorter connections, you can enjoy themed gardens, rest areas, showers, and a wide range of dining and shopping without leaving the terminal. With more time, you may join an official transit tour of Singapore if your schedule and entry requirements allow, giving you a glimpse of the city before returning airside. Your time at the airport is more than just a wait — it is an integral part of your journey.

Vietnam operates on a single time zone, Indochina Time (UTC+7), and does 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 Vietnam is typically 15 hours ahead of San Francisco during Pacific Standard Time and 14 hours ahead during Pacific Daylight Time.

Yes, your baggage will typically be checked through to your final destination in Vietnam 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.

You may be able to plan a stopover at the layover city on your journey to Vietnam, 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.
