Singapore Airlines offers one of the more generous baggage policies among global airlines, particularly for long-haul travellers.
Cabin baggage allowances depend on your class of travel, with Economy and Premium Economy passengers permitted one cabin bag up to 7kg, while Business, First and Suites passengers can bring two cabin bags up to 7kg each.
Singapore Airlines uses both weight and piece baggage systems depending on the route, which can make baggage rules slightly more complex for international travellers.
For most international routes, checked baggage is based on total weight allowance, while flights to and from the USA and Canada use a piece-based system with set bag quantities and weight limits.
Additional baggage can usually be purchased online before departure at discounted rates.
As with all airlines, UK airport liquid rules still apply for cabin baggage, meaning liquids should normally remain within 100ml containers when travelling through airport security.

Singapore Airlines baggage systems explained
Singapore Airlines uses different baggage systems depending on your route and destination.
Weight Concept
Most Singapore Airlines routes use a total weight allowance system for checked baggage.
Under the Weight Concept, your fare determines the total combined baggage weight you may check in, rather than the number of individual bags.
Economy fares typically include between 25kg and 30kg of checked baggage depending on fare type, while Premium Economy, Business Class and Suites passengers receive larger allowances.
Passengers may spread their allowance across multiple bags provided individual checked bags do not exceed 32kg.
This system is commonly used on routes across Europe, Asia, Australia, the Middle East and most international destinations outside the USA and Canada.
Piece Concept
Flights to and from the United States and Canada use a piece-based baggage system instead.
Under the Piece Concept, passengers are permitted a fixed number of checked bags with individual weight limits per bag.
Economy and Premium Economy passengers can usually check two bags up to 23kg each, while Business Class, First Class and Suites passengers can check two bags up to 32kg each.
The exact baggage allowance depends on your route, fare type and cabin class, so passengers should always confirm their baggage allowance before travelling.
For some mixed-airline or codeshare itineraries, the baggage policy of the operating airline may apply instead.
Checked baggage with Singapore Airlines: what you need to know
Singapore Airlines includes checked baggage on nearly all fares, making it more generous than many low-cost and short-haul airlines.
For most international routes, the airline uses a weight-based baggage system where passengers receive a total baggage allowance depending on their cabin class and fare type.
Economy fares typically include either 25kg or 30kg, Premium Economy includes 35kg, Business Class includes 40kg and Suites or First Class include up to 50kg.
For flights involving the USA or Canada, Singapore Airlines instead applies a piece-based baggage system.
In these cases, Economy and Premium Economy passengers can normally check two bags up to 23kg each, while Business and First Class passengers can check two bags up to 32kg each. Individual checked bags cannot exceed 32kg due to international handling safety regulations.
Passengers can usually save money by pre-purchasing additional baggage online before departure.
Singapore Airlines also applies size restrictions for oversized baggage, with large items generally limited to 200 × 75 × 80cm.
Key Singapore Airlines checked baggage tips:
-
Check whether your route uses the weight or piece concept
-
Pre-purchase additional baggage online for lower prices
-
Ensure individual bags do not exceed 32kg
-
Oversized items may require special handling
-
Mixed-airline itineraries may follow different baggage rules
Singapore Airlines cabin baggage rules: liquids, extras and restrictions
Singapore Airlines allows Economy and Premium Economy passengers to bring one cabin bag up to 7kg, while Business, First and Suites passengers may bring two cabin bags up to 7kg each. The combined dimensions of each bag must not exceed 115cm.
In addition to cabin baggage, passengers may also carry one small personal item such as a handbag, laptop bag or document bag.
Although Singapore Airlines offers relatively generous cabin baggage allowances compared with many airlines, all passengers travelling from UK airports must still follow standard airport liquid restrictions.
Liquids, gels, creams and aerosols carried through security should usually remain within containers of 100ml or less and fit inside a clear resealable liquids bag.
If cabin baggage exceeds the permitted size or weight limits, it may need to be checked into the aircraft hold and additional baggage charges may apply. Regional and codeshare flights can occasionally apply different restrictions, particularly on smaller aircraft.
For travellers trying to avoid hold baggage fees or reduce airport delays, travelling with compact cabin-friendly toiletries can make packing simpler and more efficient.
