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.

If you have at least 5.5 to 6 hours between flights, you can consider joining an official transit tour to see highlights of Singapore before returning to the airport. For shorter layovers, stay airside to enjoy gardens, rest areas, play zones, and a wide variety of dining and shopping at Singapore Changi Airport. Your time at Singapore Changi Airport is more than just a wait — it is an integral part of your journey.

In Hanoi, eligible customers can relax at the SH Premium Lounge Ha Noi before departure. During your layover at Singapore Changi Airport, eligible premium cabin and frequent flyer members may be able to access facilities such as the SilverKris Lounge (First Class), SilverKris Lounge (Business Class), or KrisFlyer Gold Lounge, depending on cabin and membership status as well as the onward flight.

Hanoi follows Indochina Time (UTC+7) and does not observe daylight saving time. Seattle follows Pacific Time, which is UTC−8 in winter and UTC−7 from roughly March to early November. This means Seattle is 15 hours behind Hanoi in winter, and 14 hours behind during Seattle's daylight saving period.

Depending on your nationality and itinerary, a transit visa may be required for Singapore or the United States. We recommend checking official government websites and consulting your local consular authorities before travel, as visa rules can change.

For flights from Hanoi to Seattle via Singapore, we recommend arriving at Noi Bai International Airport at least 3 hours before your scheduled departure. This allows enough time for check-in, security clearance, and immigration, especially during busy travel periods.

On arrival in Seattle, you will proceed through immigration, collect your checked baggage, and clear customs. If you have a connecting domestic flight, follow the signs for recheck counters after customs. Allow extra time for queues, and keep your travel documents and arrival forms ready.
