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

In-flight Dining
On both sectors between Cairns, Singapore, and Siem Reap, you will be served meals appropriate to the time of day, with menus designed to offer a balance of flavour and comfort in Business Class and Economy Class.

Special Meals
We offer a range of special meals to meet specific dietary needs on this route. You can request these in advance through Manage Booking, and they will be served in place of the standard menu on your flights.

Book the Cook
Eligible Business Class customers on the long-haul sector to and from Singapore can use our Book the Cook service, pre-selecting main courses from an expanded menu for a more personalised dining experience.

Beverage Service
Throughout your journey, you can enjoy a selection of hot and cold drinks, including juices, soft drinks, tea, and coffee. Our signature Singapore Sling is also available on board, alongside a curated range of wines and other beverages.

For flights between Cairns and Siem Reap, the weight concept applies. In Economy Class, Lite and Value fares include 25kg of checked baggage, while Standard and Flexi fares include 30kg. In Business Class, the checked baggage allowance is 40kg. Each checked bag must not exceed 32kg.

For cabin baggage, Economy Class passengers may bring 1 piece up to 7kg. Business Class passengers may bring 2 pieces, each up to 7kg. Your final baggage allowance is shown on your e-ticket, and KrisFlyer Elite Gold and PPS Club members enjoy additional allowances on eligible flights.

Wi-Fi is available on Singapore Airlines flights on this route once the aircraft is above 10,000 feet. It is free and unlimited for KrisFlyer members; 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 suitable for messaging, email, and basic browsing, but it does not support video streaming, video calls, or large file transfers.

On both the Airbus A350-900 between Cairns and Singapore and the Boeing 737-8 MAX between Singapore and Siem Reap, Economy Class offers a seat pitch of around 32 inches, with seat widths of up to 19 inches. This provides a comfortable amount of legroom for the journey.

Business Class on both sectors features seats that convert into fully flat beds, with generous personal space and direct aisle access on the Airbus A350-900, and a similar lie-flat experience on the Boeing 737-8 MAX. This allows you to rest more fully on both legs of your trip.

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.

At Singapore Changi Airport, eligible customers may be able to use facilities such as the SilverKris Lounge (First Class), SilverKris Lounge (Business Class), or KrisFlyer Gold Lounge, depending on their cabin class and frequent flyer status.

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

Singapore Changi Airport offers a wide range of facilities, from themed gardens and art installations to rest areas and transit hotels, making it easy to relax between your Cairns and Siem Reap flights. For shorter layovers, you can enjoy the terminals airside, visit a garden, or freshen up with a shower.

With a longer connection of around 5.5 hours or more, you may be able to join an official free transit tour into the city, subject to your flight timings and immigration requirements. This can be a convenient way to see highlights of Singapore before returning to the airport for your onward flight.

If you prefer to stay airside, there are family zones, quiet seating areas, and a variety of dining and shopping options spread across the terminals. Your time at Singapore Changi Airport is more than just a wait — it is an integral part of your journey.

Cairns follows Australian Eastern Standard Time (AEST), which is UTC+10 and does not observe daylight saving. Siem Reap follows Indochina Time, which is UTC+7 and also does not observe daylight saving. This means Siem Reap is 3 hours behind Cairns throughout the year.

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