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. Eligible customers may have access to facilities such as the SilverKris Lounge (First Class), SilverKris Lounge (Business Class), or the KrisFlyer Gold Lounge in Singapore (SIN).

Singapore Changi Airport is well suited to both short and longer layovers. If you have at least around 5.5 to 6 hours between flights, you can consider joining one of the official free transit tours into the city, which showcase highlights such as the skyline and waterfront areas.

For shorter layovers, staying airside gives you access to indoor gardens, rest zones, quiet seating, and in some terminals, attractions such as a butterfly garden or viewing decks. There are also showers, children’s play areas, and airport hotels if you prefer to rest in a private room.

Dining and shopping options are extensive, ranging from quick snacks to full-service restaurants and a wide range of international and regional brands. 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 March to early November). Chengdu follows China Standard Time year-round, at UTC+8. This means Chengdu is 16 hours ahead of Seattle during Pacific Standard Time, and 15 hours ahead during Pacific Daylight Time.

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