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.

Singapore Changi Airport offers a wide range of ways to spend your layover, from themed gardens and restful seating zones to playgrounds and art installations. With a longer layover of at least around 5.5 to 6 hours, you can also consider joining an official city tour, which lets you experience highlights of Singapore before returning airside.
