We offer a range of special meals that can be requested before departure to suit different dietary needs, which will be served on both sectors of your journey.

For flights between Bangkok and Phnom Penh, our weight concept applies. In Economy Class, checked baggage allowances are 25kg for Lite and Value fares, and 30kg for Standard and Flexi fares. Premium Economy Class, where offered on the Bangkok–Singapore sector, includes 35kg of checked baggage. Business Class includes 40kg of checked baggage. Each checked bag must not exceed 32kg. For cabin baggage, Economy Class and Premium Economy Class may bring 1 piece up to 7kg, while Business Class may bring 2 pieces, each up to 7kg. Your final allowance is shown on your e-ticket, and KrisFlyer Elite Gold and PPS Club members enjoy additional allowances.

Wi-Fi is available on most Singapore Airlines flights on this route once the aircraft is above 10,000 feet. It is free and unlimited for KrisFlyer members; Economy Class and Premium Economy Class customers should 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 Bangkok–Singapore and Singapore–Phnom Penh sectors, Economy Class seats offer a 32-inch pitch with up to 19-inch seat width. Business Class provides a fully flat bed with direct aisle access on these flights, giving you ample personal space to rest or work during your journey.

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. Eligible customers may be able to access facilities such as the SilverKris Lounge (First Class), SilverKris Lounge (Business Class), or KrisFlyer Gold Lounge, depending on their travel class and membership 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 Bangkok but have a Business Class onward flight from Singapore, you get lounge access in Singapore only.

Singapore Changi Airport is well suited to layovers of many lengths. If you have at least 5.5 to 6 hours between flights, you can consider joining an official transit tour into the city, subject to arrival time and tour availability. For shorter layovers, you can stay airside and enjoy themed gardens, rest areas, and family zones across the terminals. Depending on your terminal, you may also find facilities such as a swimming pool, cinema, and transit hotel rooms bookable by the hour, allowing you to refresh or rest before your next sector. Your time at Singapore Changi Airport is more than just a wait — it is an integral part of your journey.

Bangkok and Phnom Penh are in the same time zone for most practical purposes. Both cities observe a UTC+7 time offset and do not use daylight saving time, so there is no time difference between Bangkok and Phnom Penh at any time of the year.

Yes, your baggage will typically be checked through to Phnom Penh International Airport when flying from Bangkok 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 (Bangkok–Singapore and Singapore–Phnom Penh) 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 Phnom Penh 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 Bangkok–Phnom Penh 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.
