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.

For a layover at Singapore Changi Airport, you can join the airport s official transit tour into the city if your connecting time allows, usually requiring at least 5.5 hours between flights. If you prefer to stay airside, you will find gardens, rest areas, play spaces, and shower facilities to help you recharge. Eligible customers can also relax in lounges such as the SilverKris Lounge (First Class), SilverKris Lounge (Business Class), or KrisFlyer Gold Lounge. Your time at Singapore Changi Airport is more than just a wait — it s an integral part of your journey.

Before your flight from Hanoi, eligible customers may be able to access facilities such as the SH Premium Lounge Ha Noi, depending on cabin class and frequent flyer status. Lounge access offers quiet seating, refreshments, and workspace to help you prepare for your journey.

If you are travelling on a single Singapore Airlines itinerary from Hanoi to San Francisco via Singapore, we will usually check your baggage through to your final destination. You can confirm this at check-in in Hanoi, and your baggage tag and boarding passes will show your routing.

Hanoi follows Indochina Time (UTC+7) and does not observe daylight saving time. San Francisco follows Pacific Time, which is UTC-8 in winter (roughly November to March) and UTC-7 in summer (roughly March to November). This means San Francisco is 15 hours behind Hanoi in winter and 14 hours behind in summer.

On arrival at San Francisco International Airport, you will clear immigration and customs before collecting your checked baggage. The airport offers clear wayfinding in English, information counters, and options for onward travel by train, bus, shuttle, or private transport. It is helpful to confirm your chosen ground transport in advance.

For international flights from Hanoi to San Francisco via Singapore, we recommend arriving at the airport at least 3 hours before your scheduled departure time. This gives you enough time for check-in, security screening, and immigration, especially during busy travel periods.

Visa and entry requirements for travel from Hanoi to San Francisco depend on your nationality, passport type, and purpose of visit. We recommend checking with the relevant embassy or consulate, or official government websites, well before departure to ensure you have the correct documents.

If your flights from Hanoi to Singapore and from Singapore to San Francisco are on a single Singapore Airlines booking, you will usually remain in transit and your checked baggage will be transferred automatically. Always confirm this at check-in in Hanoi and review your baggage tags before leaving the counter.

For this long journey, consider wearing comfortable clothing, staying hydrated, and moving around the cabin when it is safe to do so. You may wish to pack any medication, a light layer, and personal essentials in your cabin baggage so they are within easy reach during the flight.
