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 invited to lounges such as the SilverKris Lounge (First Class), SilverKris Lounge (Business Class), or the KrisFlyer Gold Lounge.

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 offers a wide range of ways to spend your layover between Seattle and Seoul. For longer connections of at least 5.5 to 6 hours, you can consider joining one of the airport's free transit tours into the city, subject to eligibility and schedules. Shorter layovers can be comfortably spent in the terminals, where you will find gardens, quiet rest areas, snooze zones, and entertainment spaces. There are also transit hotels if you prefer more privacy and rest. 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 November to March for standard time, and March to November for daylight saving time). Seoul uses Korea Standard Time year-round, which is UTC+9 and does not observe daylight saving. This means Seoul is 17 hours ahead of Seattle during Seattle's standard time, and 16 hours ahead during Seattle's daylight saving time.

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