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.

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 Hong Kong but have a Business Class onward flight from Singapore, you get lounge access in Singapore only. In Singapore, eligible customers can enjoy The Private Room, the SilverKris Lounge (First Class), the SilverKris Lounge (Business Class), or the KrisFlyer Gold Lounge, depending on cabin class and status.

With a layover at Singapore Changi Airport, you can choose from a wide range of experiences. For longer connections, you may join an official city tour if your schedule allows, which typically requires several hours of transit time to clear formalities and return comfortably. This lets you see selected highlights of Singapore between flights.

If you prefer to stay airside, Changi Airport offers themed gardens, quiet rest areas, and entertainment zones where you can relax or walk between terminals. You can also enjoy facilities such as play areas, snooze zones, and a wide choice of dining outlets.

Whether you are stretching your legs on a nature trail, watching aircraft movements from large windows, or unwinding in a lounge, your time at Singapore Changi Airport is more than just a wait — it is an integral part of your journey.

Hong Kong follows Hong Kong Time (UTC+8) and does not observe daylight saving time. Seattle follows Pacific Time, which is Pacific Standard Time (UTC−8) from roughly November to March, and Pacific Daylight Time (UTC−7) from roughly March to November. This means Seattle is typically 16 hours behind Hong Kong in winter and 15 hours behind in summer.

Yes, your baggage will typically be checked through to Seattle-Tacoma International Airport when flying from Hong Kong 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 (Hong Kong–Singapore and Singapore–Seattle) 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 Seattle 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 Hong Kong–Seattle 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.
