Singapore Airlines Baggage Allowance: Carry-On, Checked Bags & Fees Explained
Estimated reading time: 11 mins
I’ll be honest with you. I’ve stood at a check-in desk with a bag that was “definitely under 30 kilos” and watched the scale disagree with me. Twice. And both times it was flying with Singapore Airlines, which is ironic because they’re one of the more generous airlines out there when it comes to luggage.
The thing is, Singapore Airlines baggage allowance isn’t complicated. But it is easy to get wrong, especially if you’ve booked a cheaper fare, you’re connecting through Changi, or you’re flying to the US (where the rules change completely). This guide breaks it all down. What you get, what costs extra, and how to dodge the fees. No fluff, no jargon. Just the stuff you actually need.
Singapore Airlines Baggage Allowance: Quick Facts at a Glance
✅ Singapore Airlines uses two baggage systems: weight concept (most routes) and piece concept (USA and Canada routes)
✅ Economy carry-on: 1 bag, max 7kg, max dimensions 56 x 36 x 23cm (total 115cm)
✅ Business, First and Suites carry-on: 2 bags, each max 7kg, same size limits
✅ Economy checked baggage ranges from 25kg (Lite fare) to 35kg (Flexi fare) on weight-concept routes
✅ Business Class gets 40kg; First Class and Suites get 50kg on weight-concept routes
✅ USA/Canada routes: Economy gets 2 pieces at 23kg each; Business/First gets 2 pieces at 32kg each
✅ No single bag can exceed 32kg, regardless of your class or fare type
✅ You can pre-purchase extra baggage online and save up to 25% versus paying at the airport
✅ KrisFlyer Elite Gold members get an extra 20kg on weight-concept routes
✅ The biggest mistake? Assuming all Economy tickets come with the same allowance. They don’t. Lite fares get 10kg less than Flexi
🔹 Tinker’s Tip: Always check your e-ticket or booking confirmation for your exact allowance. It’s printed right there, and it’s the single fastest way to avoid surprises.
Baggage Allowance Quick Q&As
What is Singapore Airlines’ baggage allowance? It depends on your cabin class, fare type, and destination. Economy passengers on most routes get between 25kg and 35kg of checked luggage, plus one 7kg carry-on bag.
How much does excess baggage cost on Singapore Airlines? Excess baggage is charged per kilogram and varies by route. Rates range from roughly USD 6 to USD 42 per kg (around £5 to £33 / €6 to €39), depending on where you’re flying.
What size is the carry-on allowance? Your cabin bag can’t exceed 56 x 36 x 23cm (that’s 115cm total when you add length, width and height together). Maximum weight is 7kg per bag.
Can I pre-purchase extra baggage to save money? Yes. You can buy additional baggage online via Manage Booking up to 6 hours before departure, with discounts of 10% to 25% off airport rates.
What’s the difference between weight and piece concept? Weight concept (most routes) means your total bag weight matters, not the number of bags. Piece concept (USA and Canada) limits you to a set number of bags, each with a weight cap.
How early should I sort out my baggage to avoid problems? Buy extra baggage more than 48 hours before departure for the best discount. And weigh your bags at home the night before.
👉 Good to know: On weight-concept routes, you can split your allowance across as many bags as you like, as long as no single bag tops 32kg and the combined weight stays within your limit.
Singapore Airlines Baggage Allowance: What You Actually Get
Right. Let’s get the full picture. Singapore Airlines is more generous than a lot of carriers, but your exact allowance depends on three things: your cabin class, your fare type, and your destination.
For most routes, SQ uses the weight concept. That means the total weight of all your checked bags matters, but you can split it across multiple bags (as long as nothing exceeds 32kg per piece). Flying to or from the USA or Canada? It switches to the piece concept, which limits the number of bags and weight per bag instead.
| Cabin Class | Weight Concept (most routes) | Piece Concept (USA/Canada) | Carry-On |
| Economy Lite | 25kg total | 2 bags, 23kg each | 1 bag, 7kg |
| Economy Standard | 30kg total | 2 bags, 23kg each | 1 bag, 7kg |
| Economy Flexi | 35kg total | 2 bags, 23kg each | 1 bag, 7kg |
| Premium Economy | 35kg total | 2 bags, 23kg each | 1 bag, 7kg |
| Business Class | 40kg total | 2 bags, 32kg each | 2 bags, 7kg each |
| First Class / Suites | 50kg total | 2 bags, 32kg each | 2 bags, 7kg each |
💡 Fact: Suites Class passengers get 50kg of checked baggage on weight-concept routes. That’s basically a small wardrobe. Most of us won’t need that, but it’s nice to dream.

Carry-On Rules: Size, Weight, and What Counts as a Personal Item
This is where people get caught out more than you’d expect. I once watched a bloke at Changi try to board with a duffel bag roughly the size of a Labrador. It did not end well for him.
In Economy and Premium Economy, you get one cabin bag up to 7kg and no bigger than 56 x 36 x 23cm. In Business, First, and Suites, you get two cabin bags, each with the same limits.
On top of that, everyone gets one personal item for free. Handbag, laptop bag, or camera bag. The restriction is that it can’t exceed 40 x 30 x 10cm. Your standard laptop sleeve or small crossbody is fine, but anything bulkier might get flagged. If your personal item exceeds 80cm total dimensions, it counts as your main cabin bag instead.
You can also carry a few extras at no charge: a walking stick or crutches if needed, duty-free purchases (within destination rules), and infant amenities up to 6kg if you’re travelling with a baby.
🔹 Tinker’s Tip: Pack your heaviest items (laptop, chargers, travel adaptor, book) into your personal item. It doesn’t count toward the 7kg carry-on limit and can free up real weight in your main bag.

Checked Baggage by Fare Type: Lite vs Standard vs Flexi
This is the bit that catches most travellers. Not all Economy tickets are created equal, and the difference between fare types is significant.
Economy Lite (the cheapest option) gives you just 25kg on weight-concept routes. Standard bumps that to 30kg, and Flexi gives you 35kg. That’s a 10kg gap between the cheapest and most flexible Economy tickets, which can absolutely be the difference between packing comfortably and doing the awkward luggage shuffle at check-in.
Premium Economy matches Flexi at 35kg. Business jumps to 40kg, and First/Suites get 50kg. On USA and Canada routes, the piece concept means all Economy passengers get 2 bags at 23kg each regardless of fare type.
Most people flying long-haul from the UK tend to book Standard or Flexi, which means 30 to 35kg. That’s plenty for a two-week holiday, even if you’re the type who packs “just in case” outfits. Infants (not occupying a seat) get 10kg of checked baggage, plus a stroller and car seat at no extra charge.
👉 Good to know: On piece-concept routes (USA/Canada), the fare type matters less for checked bags. All Economy passengers get the same 2 x 23kg allowance. It’s only on weight-concept routes where Lite vs Flexi creates a big gap.

Excess Baggage Fees: What They Charge and How to Dodge Them
Here’s the part nobody wants to deal with. Excess baggage on Singapore Airlines is charged per kilogram on weight-concept routes, and the cost varies by destination band.
| Route Band | Example Destinations | Pre-Purchase Rate (per kg) | Airport Rate (per kg) |
| Band 1 | Malaysia, Thailand, Vietnam | ~USD 6-8 / £5-6 / €6-7 | ~USD 8-10 / £6-8 / €7-9 |
| Band 2 | China, Japan, Korea, Middle East | ~USD 10-12 / £8-10 / €9-11 | ~USD 14-16 / £11-13 / €13-15 |
| Band 3 | Australia, New Zealand | ~USD 16-20 / £13-16 / €15-19 | ~USD 22-28 / £17-22 / €20-26 |
| Band 4 | Europe, Africa | ~USD 22-30 / £17-24 / €20-28 | ~USD 30-42 / £24-33 / €28-39 |
For USA and Canada routes, additional bags cost around USD 150 per extra piece, with overweight charges of roughly USD 100 per heavy or oversized bag.
The smartest move? Buy extra weight online before you fly. Singapore Airlines offers a 25% discount if you purchase more than 48 hours before departure, or 10% off between 48 and 6 hours before departure. After that, you’re paying full whack at the airport.
I once paid airport-rate excess from Singapore to London. About USD 35 per kilo, 4kg over. That’s USD 140 I could’ve spent on laksa and cold beers instead. Learn from my mistakes.
✋🏼 Must-do: Weigh your bags at home the night before. A cheap digital luggage scale costs about £8 / $10 / €9 and will pay for itself the first time you use it.

Pre-Purchasing Extra Baggage and KrisFlyer Perks
If you already know you’ll need more luggage room, pre-purchasing is the single best way to save money. Log into Manage Booking on the SQ website or app, and you’ll see the option to add extra baggage. On weight-concept routes you can buy in blocks of 1kg up to 100kg. For USA/Canada routes, you can add up to 2 extra pieces.
KrisFlyer members get additional discounts on top. Even the free basic membership unlocks slightly better rates. At the higher tiers, the perks get properly useful. Elite Silver gets an extra 10kg on weight-concept routes. Elite Gold and Star Alliance Gold get 20kg extra. PPS Club members get double their standard allowance (so a PPS Business passenger would have 80kg). On piece-concept routes, Gold members get one additional bag and PPS members get two extra.
Important detail: these bonus allowances only apply on flights actually operated by Singapore Airlines. Codeshare flights use the operating airline’s baggage policy instead. I found that out the hard way on a Lufthansa-operated codeshare. Always check the operating carrier.
💡 Fact: PPS Club travel companions get a 40% discount on pre-purchased additional baggage. Elite Gold companions get 35% off. Worth remembering if you’re travelling with someone who has status.

Sports Equipment, Oversized Items, and Special Luggage
Golf clubs, surfboard, bicycle? Singapore Airlines allows it, but there are rules. Sports equipment counts toward your standard checked allowance. If it pushes you over, normal excess fees apply.
Maximum dimensions for any single item are 200 x 75 x 80cm, and the 32kg safety limit still applies per piece. Bicycles must be non-motorised with handlebars fixed sideways and pedals removed. Scuba tanks must be empty. Inflatable balls need deflating. Surfboards need a hard protective case. Motorised bicycles and hoverboards are completely banned.
For musical instruments, smaller ones like violins can go in the cabin in place of your standard cabin bag if they meet the 7kg and 115cm limits. Larger instruments like cellos can travel in a purchased seat (up to 40kg, max 127 x 45 x 30cm).
👉 Good to know: If you’re bringing sports gear, contact Singapore Airlines in advance. Some items need prior approval, and turning up at check-in with an unannounced surfboard creates delays you really don’t need.

Liquids, Cabin Restrictions, and the Rules That Still Trip People Up
You’d think we’d all have this figured out by now. I watched someone lose a full-size bottle of hot sauce at Changi security last year. Genuinely heartbreaking.
The rules are universal and SQ enforces them strictly. Any liquids, gels, aerosols, creams, or pastes in your cabin baggage must be in containers of 100ml or less. All go inside a single clear, resealable bag with a 1-litre capacity. One bag per passenger. For checked baggage, liquids are generally fine but alcohol-based sanitisers are capped at 0.5L per item and 2L total. Lithium batteries and power banks must go in cabin baggage, not checked.
And one uniquely Singapore Airlines rule: durians are banned from both cabin and checked baggage. If you’re arriving into Singapore and want to stay connected from the moment you land, picking up an eSIM before you fly saves you hunting for a SIM card at Changi.
Connecting Flights, Codeshares, and What to Do When Things Go Wrong
When you’re connecting through Singapore (which a lot of UK travellers do on long-haul routes to Asia or Australia), baggage rules can get murky.
The general rule: if all flights are on a single ticket, the baggage policy of the most significant marketing carrier applies. For USA routes, the first marketing carrier’s rules apply. Codeshare legs operated by another airline may follow that airline’s policy. Always check your e-ticket for the exact allowance per segment.
If your luggage goes missing, head straight to the SQ baggage counter before leaving arrivals. They’ll file a report and start tracing. The SingaporeAir app also offers tracking through MyTrips. Under the Montreal Convention, airlines are liable up to around 1,288 SDR (roughly £1,350 / $1,700 / €1,580). Claiming can be slow though, which is why travel insurance that covers baggage is worth having. If your flight was seriously disrupted, you might also be entitled to flight compensation depending on the circumstances.
✋🏼 Must-do: Screenshot your e-ticket baggage details on your phone. When a ground agent at a connecting airport asks about your allowance, having it right there saves a lot of back and forth.

FAQs
Can I buy extra baggage allowance after booking with Singapore Airlines?
Yes. You can add extra baggage through Manage Booking on the Singapore Airlines website or app. Best rates come when you purchase more than 48 hours before your flight (25% off). Between 48 and 6 hours gives you 10% off. After that, it’s full price at check-in.
What happens if my bag is overweight at Singapore Airlines check-in?
You’ll be charged excess baggage fees based on the per-kilogram rate for your route. On piece-concept routes (USA/Canada), overweight bags incur a flat fee of around USD 100. You might also be asked to redistribute items between bags.
Does Singapore Airlines charge for carry-on bags?
No. Your cabin baggage allowance is included with every ticket. Economy and Premium Economy get one bag (7kg, 115cm total), Business, First, and Suites get two bags with the same limits. You also get a free personal item up to 40 x 30 x 10cm.
Are Singapore Airlines baggage rules different for connecting flights?
They can be. If all flights are on a single ticket with SQ as marketing carrier, their rules generally apply throughout. Codeshare segments operated by other airlines may follow that airline’s policy instead. For USA routes, the first marketing carrier’s rules apply for the entire journey.
What counts as a personal item on Singapore Airlines?
A personal item is a small bag you bring into the cabin for free on top of your main cabin bag. It includes handbags, laptop bags, or camera bags. Maximum dimensions are 40 x 30 x 10cm. If the item exceeds 80cm total dimensions, it counts as your main cabin bag instead.
Wrapping Up: Before You Fly SA
Singapore Airlines is one of the better airlines for baggage. The allowances are generous, especially in Business and above. But the system has enough moving parts that it’s worth getting your head around before you fly.
Three things that make the biggest difference: check your fare type and know your exact allowance, pre-buy extra baggage online if you need it, and weigh your bags at home. Do those three and you’ll breeze through check-in.
