Flights from Siem Reap (SAI) to Cairns (CNS)

In-flight Dining
You will be served meals on both sectors of your Siem Reap–Cairns journey, with menus designed to suit the time of day and flight duration. Dishes are thoughtfully prepared to retain flavour at altitude.

Special Meals
We offer a range of special meals on this route, which must be requested before departure. You can make your selection during booking or by managing your reservation online ahead of your flight.

Book the Cook
Eligible premium cabins on selected Singapore Airlines flights can pre-order main courses through our Book the Cook service. Availability depends on your specific flight sector and cabin, and you can view current options when managing your booking.

Beverage Service
Throughout the flight, you can enjoy hot and cold beverages, including juices, soft drinks, teas, and coffee. A selection of wines and spirits is available, and our signature Singapore Sling is offered on board.

For flights between Siem Reap and Cairns, the weight concept applies. Checked baggage allowances are: Economy Class (Lite and Value fares: 25kg; Standard and Flexi: 30kg) and Business Class (40kg). Each checked bag must not exceed 32kg. Cabin baggage allowances are: Economy Class (1 piece, up to 7kg) and Business Class (2 pieces, each up to 7kg). Your final allowance is confirmed on your e-ticket, and KrisFlyer Elite Gold and PPS Club members enjoy additional allowances.

Wi-Fi is available on Singapore Airlines flights from Siem Reap to Cairns once the aircraft is above 10,000 feet. It is free and unlimited for KrisFlyer members, although Economy Class members must add their membership number to the booking at least 1.5 hours before departure. Non-members can purchase access plans. The service is ideal for messaging, email, and basic browsing, but it does not support video streaming, video calls, or large file transfers.

On both the Boeing 737-8 MAX between Siem Reap and Singapore, and the Airbus A350-900 between Singapore and Cairns, Economy Class typically offers a 32-inch seat pitch with up to 19-inch seat width. Business Class provides a fully flat bed on the Airbus A350-900 and a spacious recliner-style seat on the Boeing 737-8 MAX, with generous legroom and direct aisle access on the Airbus A350-900.

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

At Singapore Changi Airport, you can enjoy themed gardens, quiet rest areas, play zones, and a wide range of dining options, all designed to make your layover comfortable. For longer connections, you may be able to join an official transit tour into the city, which generally requires at least 5.5–6 hours of spare time. Shorter layovers are well spent exploring the terminals, relaxing in seating zones, or refreshing at pay-per-use lounges and transit hotels. Your time at Singapore Changi Airport is more than just a wait — it is an integral part of your journey.

Siem Reap follows Indochina Time (UTC+7) all year round. Cairns follows Australian Eastern Standard Time (UTC+10) and does not observe daylight saving time. This means Cairns is 3 hours ahead of Siem Reap throughout the year.

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