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.

At Singapore (SIN), eligible customers may use lounges such as the SilverKris Lounge (First Class), SilverKris Lounge (Business Class), and KrisFlyer Gold Lounge, depending on their cabin 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 Busan but have a Business Class onward flight from Singapore, you get lounge access in Singapore only.

Singapore Changi Airport is well suited to both short and longer layovers, with themed gardens, rest areas, and family-friendly facilities across its terminals. For layovers of at least around 5.5 to 6 hours, you can consider joining one of the airport’s official free transit tours, which gives a glimpse of the city between your flights. For shorter transits, you can stay airside, enjoy landscaped spaces, quiet zones, and a wide range of dining and shopping options. Your time at Singapore Changi Airport is more than just a wait — it is an integral part of your journey.

Busan follows Korea Standard Time (UTC+9) and does not observe daylight saving time. Seattle operates on Pacific Standard Time (UTC−8) roughly from November to March, making Seattle 17 hours behind Busan, and on Pacific Daylight Time (UTC−7) from March to November, making Seattle 16 hours behind Busan.

Yes, your baggage will typically be checked through to Seattle-Tacoma International Airport (SEA) when flying from Busan 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 (Busan–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 Busan–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.
