On flights between the United States and Vietnam, Singapore Airlines generally applies the piece concept for checked baggage.

Cabin baggage allowances also vary by cabin, with higher limits in premium cabins. Exact entitlements depend on your ticket type and KrisFlyer status, so please refer to your e-ticket or our baggage calculator before you travel.

Wi-Fi is available on most flights from Seattle to Vietnam once the aircraft is above 10,000 feet.

Non-members and guests who do not register in time can purchase paid plans. The connection is suitable for messaging, email, and basic browsing, but it does not support video streaming, video calls, or large file transfers.

Most flights from Seattle to Vietnam connect via Singapore Changi Airport. If you have a longer layover, you can join a free transit tour into the city, subject to timing and eligibility, or simply explore the terminals. For shorter stays, Changi offers indoor gardens, quiet rest areas, swimming pools, showers, play zones, art installations, and extensive shopping and dining, so you can refresh and relax between flights. Your time at the airport is more than just a wait — it is an integral part of your journey.

Seattle is in the Pacific Time Zone (UTC−8, UTC−7 during daylight saving time from roughly March to early November). Vietnam follows Indochina Time (UTC+7) and does not observe daylight saving. This means Vietnam is typically 15 hours ahead of Seattle in winter and 14 hours ahead in summer, for Ho Chi Minh City, Da Nang, and Hanoi.

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.
