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 Seattle but have a Business Class onward flight from Singapore, you get lounge access in Singapore only. In Singapore (SIN), eligible customers can access facilities such as the SilverKris Lounge (First Class), SilverKris Lounge (Business Class), and KrisFlyer Gold Lounge.

Singapore Changi Airport is well known for its range of transit experiences, including gardens, themed zones, and rest areas that make even short layovers enjoyable. For longer connections, you can join the official free transit tour programme, which typically requires a layover of at least 5.5 to 6 hours, subject to eligibility and operating hours. If you prefer to stay airside, explore the airport's indoor gardens, relaxation zones, and dining options spread across its terminals. 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 (approximately November to March) and UTC−7 in summer (approximately March to November) due to daylight saving time. Colombo stays on Sri Lanka Standard Time all year at UTC+5:30. This means Colombo is 13.5 hours ahead of Seattle in winter and 12.5 hours ahead in summer.

Yes, your baggage will typically be checked through to Bandaranaike International Airport (Colombo) 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–Colombo) 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 Colombo 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–Colombo 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.
