For flights between Colombo and Bangkok, the weight concept applies. Checked baggage allowances are: Economy Class (Lite and Value fares: 25kg; Standard and Flexi fares: 30kg) and Business Class (40kg). Each checked bag must not exceed 32kg.

Wi-Fi is available on Singapore Airlines flights from Colombo to Bangkok 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. Paid plans are available for non-members. The connection is suitable for messaging, email, and basic browsing, but it does not support video streaming, video calls, or large file transfers.

On the Colombo to Singapore sector, Economy Class offers a seat pitch of about 32 inches with up to 19 inches of seat width, while Business Class provides a fully flat bed with direct aisle access. On the Singapore to Bangkok sector, Economy Class and Business Class offer similar comfort levels, with Economy Class featuring a 32-inch pitch and Business Class providing a fully flat bed with direct aisle access.

On this route, our aircraft feature personal in-flight entertainment screens at every seat. You can choose from a wide library of movies, television programmes, music albums, and games. Content is updated regularly, giving you many options to enjoy throughout both flight sectors.

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.

When departing from Colombo, eligible customers may be able to relax in the AASL Lotus Lounge or Araliya Lounge at Bandaranaike International Airport, depending on their cabin class or frequent flyer status. During your layover at Singapore Changi Airport, eligible customers can access the SilverKris Lounge (First Class), SilverKris Lounge (Business Class), or the KrisFlyer Gold Lounge, according to their class of travel and KrisFlyer or Star Alliance status.

At Singapore Changi Airport, longer layovers can be spent joining the official free transit tour into the city, which typically requires at least 5.5 to 6 hours between flights. Shorter layovers are well used exploring the airport's indoor gardens, themed zones, play areas, and rest spaces. You can also enjoy shopping, dining, and quiet corners for reading or working. Your time at Singapore Changi Airport is more than just a wait — it is an integral part of your journey.

For most itineraries booked on a single Singapore Airlines ticket from Colombo to Bangkok via Singapore, our team will tag your checked baggage through to Bangkok. You simply follow the transfer signs at Singapore Changi Airport and proceed to your next gate, keeping your cabin baggage and essential items with you during the layover.

Colombo follows Asia/Colombo time, which is UTC+5:30 all year. Bangkok follows Asia/Bangkok time, which is UTC+7:00 all year. This means Bangkok is 1 hour 30 minutes ahead of Colombo throughout the year, with no daylight saving time changes in either city.

When you arrive from Colombo via Singapore, you will follow signs for immigration, baggage reclaim, and customs at Bangkok Suvarnabhumi Airport. After collecting your checked baggage, you can continue to ground transport, where options include trains, public transport, and pre-arranged transfers. Check local information in advance to choose the best onward connection.

We recommend arriving at Bandaranaike International Airport at least 3 hours before your scheduled departure time for flights to Bangkok via Singapore. This allows enough time for check-in, security screening, and any border formalities before you proceed to the departure gate.

Visa and entry requirements depend on your nationality, length of stay, and travel purpose. You should check current regulations for both Thailand and any transit requirements for Singapore with official government or embassy sources before you travel, as rules may change over time.

Whether you can leave Singapore Changi Airport during your layover depends on your nationality, visa eligibility, and connection time. If you qualify for entry and have a longer layover, you may choose to go into the city. Always allow generous time to return for security checks and boarding.
