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.

You may be able to access the SilverKris Lounge (First Class), SilverKris Lounge (Business Class), or KrisFlyer Gold Lounge during your transit, depending on your eligibility.

Lounge Access Eligibility
Cabin Class: Complimentary for Suites, First, and Business Class passengers. Premium Economy and Economy travellers do not have access unless they hold eligible status.

Frequent Flyer Status: PPS Club and KrisFlyer Elite Gold (or Star Alliance Gold) members have access regardless of cabin class.

The 'Next Segment' Rule: Eligibility is based on the flight immediately departing that airport. For example, if you fly Economy from Seattle but have a Business Class onward flight from Singapore, you get lounge access in Singapore only.

Singapore Changi Airport is designed for comfortable transits, with clear wayfinding and calm seating areas across the terminals. For longer layovers, you can join one of the official free transit tours into the city if your connection meets the minimum required hours, allowing you to see highlights before returning to continue your journey.

If you prefer to stay airside, you will find themed gardens, relaxation zones, children’s play areas, and a wide range of dining options. Some terminals also feature attractions such as indoor greenery, art installations, and quiet corners ideal for resting between flights.

For an extended connection, consider booking an airport hotel or using rest areas to freshen up and adjust to the time difference. Your time at Singapore Changi Airport is more than just a wait — it is an integral part of your journey.

Seattle follows Pacific Time, which is UTC−8 in winter and UTC−7 in summer (approximately March to early November). Ho Chi Minh City follows Indochina Time, which is UTC+7 year-round. This means Ho Chi Minh City is 15 hours ahead of Seattle during Seattle’s standard time, and 14 hours ahead during daylight saving time.

Yes, your baggage will typically be checked through to Tan Son Nhat International Airport when flying from Seattle via Singapore on a single booking with Singapore Airlines.

Through-Check Conditions
For your bags to be sent directly to your final destination, the following general conditions must be met:

Single Itinerary: Both flight segments (Seattle–Singapore and Singapore–Ho Chi Minh City) must be under the same booking reference or PNR.

Layover Duration: Your connection in Singapore must be less than 24 hours. If your layover exceeds 24 hours, it is considered a stopover, and you will typically be required to collect your luggage and re-check it for your onward flight.

Partner Airlines: If your onward flight from Singapore to Ho Chi Minh City is operated by a partner airline, Singapore Airlines has through-check agreements that usually allow your bags to be tagged to your final destination.

You may be able to plan a stopover in Singapore on your Seattle–Ho Chi Minh City trip, 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.
