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 Changi Airport, you can enjoy a wide range of airside facilities, including themed gardens, quiet rest areas, and curated shopping and dining. For longer layovers, you may join one of the official airport city tours, which typically require at least a 5.5-hour transit window.

Seattle is in the America/Los_Angeles time zone, which is typically UTC-8 in winter and UTC-7 from roughly March to early November due to daylight saving time. Seoul is in the Asia/Seoul time zone, which is UTC+9 all year round. This means Seoul is usually 17 hours ahead of Seattle in winter and 16 hours ahead in summer.

When you fly from Seattle to Seoul with us, your bags are usually checked through to your final destination, and you can follow clear transit signs at Singapore Changi Airport. Transfer security and gate checks are efficient, but we recommend checking your boarding passes for terminal and boarding time details on arrival.

For this long-haul journey with a connection in Singapore, we recommend arriving at Seattle-Tacoma International Airport at least 3 hours before your scheduled departure. This allows enough time for check-in, security screening, and a relaxed arrival at the gate.

You should ensure that your passport is valid for the required period beyond your stay in South Korea and that you hold any necessary visas or electronic travel authorisations. Requirements vary by nationality, so we recommend checking official government sources and our website before you travel.
