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 Osaka but have a Business Class onward flight from Singapore, you get lounge access in Singapore only.

In Singapore (SIN), eligible passengers may use lounges such as the SilverKris Lounge (First Class), SilverKris Lounge (Business Class), and KrisFlyer Gold Lounge, depending on cabin and status.

Singapore Changi Airport is designed for comfortable and engaging layovers, with themed gardens, art installations, and quiet seating areas throughout the terminals. For shorter connections, you can enjoy walking trails, viewing galleries, and rest zones close to your gate.

With a longer layover of at least around 5.5 to 6 hours, you may be able to join one of the airport's official transit tours into the city, subject to timing and eligibility. These curated tours give you a brief introduction to Singapore's skyline, waterfront areas, and key neighbourhoods before returning you to the airport.

If you prefer to stay airside, you will find showers, nap spaces, playgrounds, and a wide choice of dining and retail options, as well as airport hotels within the terminals. Your time at Singapore Changi Airport is more than just a wait — it is an integral part of your journey.

Osaka follows Japan Standard Time (UTC+9) and does not observe daylight saving time. Siem Reap follows Indochina Time (UTC+7), also without daylight saving time. This means Siem Reap is 2 hours behind Osaka throughout the year, so when it is 12.00pm in Osaka, it is 10.00am in Siem Reap.

Yes, your baggage will typically be checked through to Siem Reap International Airport when flying from Osaka 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 (Osaka–Singapore and Singapore–Siem Reap) 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 Siem Reap 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 Osaka–Siem Reap 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.
