Wi-Fi is available on Singapore Airlines flights from Seattle to Hong Kong once the aircraft is above 10,000 feet. It is free and unlimited for KrisFlyer members, and Economy Class and Premium Economy Class customers should add their membership number to the booking at least 1.5 hours before departure.

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. Eligible customers may be able to use facilities such as the SilverKris Lounge (First Class), SilverKris Lounge (Business Class), or the KrisFlyer Gold Lounge, depending on their travel class and membership status.

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 well suited to relaxing during your layover from Seattle to Hong Kong. For longer connections of around 5.5 hours or more, you may consider joining an official transit tour into the city, subject to eligibility and timing. For shorter stays, you can enjoy the airport’s gardens, quiet seating areas, rest zones, and a range of dining and shopping options without leaving the terminal. Your time at Singapore Changi Airport is more than just a wait — it's an integral part of your journey.

Seattle follows Pacific Time, which is UTC−8 in winter and UTC−7 during daylight saving time, roughly from March to early November. Hong Kong operates on Hong Kong Time year-round at UTC+8. This means Hong Kong is 16 hours ahead of Seattle in winter, and 15 hours ahead during Seattle’s daylight saving period.

Yes, your baggage will typically be checked through to Hong Kong 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–Hong Kong) 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 Hong Kong 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–Hong Kong 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.
