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

Singapore Changi Airport offers extensive amenities to make your layover comfortable, including themed gardens, quiet rest areas, and family-friendly spaces. For longer layovers of at least around 5.5 to 6 hours, you can consider joining one of the airport’s free transit tours, which provide a brief introduction to the city before you return airside.

For shorter connections, you may prefer to stay in the transit area, where you will find a wide choice of dining, shopping, and relaxation options, along with shower facilities and transit hotels for added rest. Clear wayfinding and efficient security processes help keep your transfer time smooth.

Your time at Singapore Changi Airport is more than just a wait — it is an integral part of your journey.

Single Itinerary: Both flight segments (Adelaide–Singapore and Singapore–Seattle) must be under the same booking reference or PNR.

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.
