Singapore Airlines Baggage Allowance 2026: Cabin and Checked Bags

Published: 12 July 2026

Singapore Airlines consistently tops “world’s best airline” lists, and its baggage rules are among the more generous in long-haul travel. The catch is how they measure the cabin bag. There’s no fixed width, height, and depth to memorise. Instead, the length, width, and height of your carry-on must add up to no more than 115 cm, and the bag must weigh 7 kg or less. A tall, slim case and a short, fat one can both pass or both fail depending on how the three numbers total. It’s worth doing the sum before you fly.

The checked side is where Singapore Airlines is genuinely generous: even the cheapest Economy Lite fare includes 25 kg, and Standard fares get 30 kg on most of the network. This guide covers the 115 cm cabin rule, the personal item, checked allowances by fare and route, KrisFlyer bonuses, infant rules, and the fees if you go over.

Quick answer:

• Economy cabin bag: 7 kg, within 115 cm total (length + width + height), plus a personal item
• Personal item: up to 40 x 30 x 10 cm, free
• Business, First, and Suites cabin: 2 bags, 7 kg each, same 115 cm limit
• Economy checked (weight concept): Lite 25 kg / Standard and Flexi 30 kg
• Premium Economy 35 kg / Business 40 kg / First and Suites 50 kg (weight concept)
• Piece concept (all routes to and from the US and Canada): Economy 2 x 23 kg, Business/First 2 x 32 kg
• Max single bag: 32 kg on every route

Singapore Airlines Baggage Allowance at a Glance

The carry-on rule is the same across every cabin: 7 kg within 115 cm total. Premium cabins simply get a second cabin bag. The checked figures rise with your fare and cabin, and switch to a piece count on US and Canada routes.

Singapore Airlines Cabin Baggage Rules

Economy — the 7 kg, 115 cm Carry-On and the Personal Item

Economy and Premium Economy passengers can bring one cabin bag plus one personal item:

• Cabin bag: 7 kg maximum, with length + width + height adding up to no more than 115 cm (a typical shape is around 56 x 36 x 23 cm)
• Personal item: up to 40 x 30 x 10 cm — a handbag, laptop bag, or slim backpack, free of charge

The 115 cm total is the number that matters. Singapore Airlines doesn’t publish a strict maximum for each side — it’s the sum that counts. Most cabin-approved suitcases sold as “55 x 40 x 20 cm” come to 115 cm exactly, so they sit right at the limit. If your bag is larger on any one dimension, add the three numbers before you assume it fits.

The 7 kg weight limit is real and enforced at check-in on many routes, especially out of Singapore Changi. Unlike some carriers that wave borderline bags through, Singapore Airlines does weigh cabin baggage. If you’re close, weigh it at home.

Business, First, and Suites

Premium cabin passengers get:

• 2 cabin bags, each up to 7 kg and within the 115 cm total
• 1 personal item under the seat

That’s a comfortable amount of hand baggage for a long-haul flight where you want your work kit and a change of clothes within reach.

What Happens If Your Cabin Bag Is Over

If your carry-on is over 7 kg or exceeds 115 cm at check-in, staff will ask you to check it, move items into your hold bag, or remove things to carry on your person. Because Singapore Airlines’ checked allowances are generous, moving weight into the hold is usually straightforward on weight concept routes, but on US routes with a piece limit, an over-limit cabin bag can mean paying for an extra piece. Weigh and measure at home.

Checked Baggage: Weight Concept vs Piece Concept

Singapore Airlines uses two systems. Most of the network — including UK–Singapore and onward across Asia and Australia — runs on weight concept, where your allowance is a total weight you can split across bags. Every route to and from the United States and Canada runs on piece concept, where you get a fixed number of bags.

Weight Concept Routes

Your allowance is a total weight, split across as many bags as you like, as long as no single bag exceeds 32 kg.

Even the cheapest Economy Lite fare includes 25 kg on weight concept routes, more than many competitors give you before you’ve paid a penny extra. A couple flying Standard can pool their combined 60 kg across their bags as long as they’re on the same booking.

Piece Concept Routes — the US and Canada

For every route to and from the United States and Canada, your allowance is counted by the number of bags rather than total weight.

On US and Canada routes, even Economy Lite gets two 23 kg bags — a genuinely generous piece allowance. Maximum single bag dimensions on piece concept routes are 158 cm total.

Maximum Weight per Bag

32 kg per individual bag, on any route and in any cabin. Singapore Airlines will not accept a single bag over 32 kg regardless of your total allowance. If one bag is over, you repack at the airport.

Singapore Airlines Economy Fares: What Each Gets You

The fares mainly change your seat selection, change fees, and mileage earning. The checked jump is from 25 kg on Lite/Value to 30 kg on Standard/Flexi. If you need more than 25 kg, compare the Standard fare against buying 5 kg of extra weight on a Lite fare; the fare upgrade sometimes wins.

Buying Extra Baggage: Online vs Airport

Singapore Airlines sells extra weight and extra pieces through Manage Booking at singaporeair.com, and pre-purchasing at least 48 hours before departure is cheaper than the airport counter. Extra weight is sold in blocks on weight concept routes; extra pieces are sold per bag on US routes.

Approximate rates as of mid-2026 (vary by route band — check at singaporeair.com):

• Weight concept routes: roughly USD 6 per kg online, higher at the airport
• Piece concept routes: around USD 120 per additional bag; USD 80 for an overweight piece

Add extra baggage early. Rates rise closer to departure, and airport prices are the highest.

Cabin Max Metz 30L Cabin Bag Backpack

The Cabin Max Metz 30L (45 x 36 x 20 cm) adds up to 101 cm total, comfortably inside Singapore Airlines’ 115 cm cabin limit. At 0.5 kg empty it leaves almost the full 7 kg for contents — which matters on an airline that actually weighs cabin bags. It opens flat like a suitcase, has a padded laptop sleeve, and drops into the overhead bin without a fight.

Singapore Airlines KrisFlyer and PPS Baggage Benefits

KrisFlyer elite members and PPS Club members earn extra baggage on Singapore Airlines flights.

An Elite Gold member on an Economy Standard fare (30 kg) effectively travels with 50 kg on weight concept routes. PPS Club members double their allowance. If your itinerary includes Star Alliance partner sectors on the same ticket, the alliance rules may apply to those legs.

Families and Infants

An infant under 2 travelling on a lap is entitled to a checked baggage allowance and one free item — a collapsible stroller or an approved car seat, carried in the hold. Cabin items for the infant (food, formula, and amenities) should be kept to what you need for the flight, within roughly 6 kg.

Strollers can usually be taken to the aircraft door and gate-checked where the airport allows, then returned on arrival.

Sports and Special Equipment

Standard sports equipment travels within your checked allowance — there’s no separate surcharge for golf clubs, skis, or a bike, but they use up your weight or piece allowance. Oversized or unusually heavy items, and anything over 32 kg in a single piece, need to be arranged in advance and may travel as cargo. Notify Singapore Airlines ahead of time for bikes and large instruments.

Lost or Delayed Baggage

If your bag doesn’t appear, go to the Singapore Airlines baggage desk before leaving the arrivals hall and file a Property Irregularity Report (PIR). You need that reference for everything that follows, and you can’t file it once you’ve left the airport.

Track the bag with your PIR reference; most delayed bags are reunited within 24–72 hours. Keep receipts for essentials you buy while you wait, as they can be claimed back. After 21 days a bag is officially declared lost, at which point liability falls under the Montreal Convention, capped at roughly 1,288 Special Drawing Rights per passenger (around £1,200–1,350 at current rates). File damage claims within 7 days and delay claims within 21 days of receiving the bag. Travel insurance with baggage cover often pays out faster than an airline claim.

Singapore Airlines vs Other Airlines

Singapore Airlines matches the 7 kg cabin limit of Emirates and Qatar, but its checked allowance is more generous from the bottom fare up: 25 kg on Economy Lite versus 20 kg on the Gulf carriers’ entry fares. The 115 cm total-dimension cabin rule is more flexible than a fixed width, height, and depth, provided you do the sum. For a full breakdown across UK and European carriers, see the UK airline baggage allowance comparison.

Practical Tips for Singapore Airlines Baggage

• Add up your cabin bag’s three dimensions. The limit is 115 cm total, not a fixed width and height. A bag that’s large on one side can still pass if the sum works.
• The 7 kg cabin limit is weighed. Singapore Airlines enforces it, especially out of Changi. Keep the carry-on light and use the personal item for the heavy small stuff — but the personal item itself should stay modest.
• Know your route concept. UK–Singapore and onward across Asia is weight concept. Anything touching the US or Canada is piece concept — a fixed two bags.
• Even Lite fares are generous. 25 kg checked on the cheapest Economy fare, and two 23 kg bags on US routes. You rarely need to pay extra.
• Add extra baggage online, 48 hours ahead. It’s cheaper than the airport and prices climb near departure.
• KrisFlyer Gold adds 20 kg. If you hold Star Alliance Gold through any airline, you get the bonus on Singapore Airlines too.

What is the Singapore Airlines cabin baggage size and weight?

How big can my carry-on be on Singapore Airlines?
Your carry-on can be any shape as long as its length, width, and height add up to 115 cm or less and it weighs 7 kg or under. A standard 55 x 40 x 20 cm cabin case adds up to 115 cm exactly, so it sits right at the limit. Add your bag’s three dimensions before travelling to be sure.

Does Singapore Airlines weigh cabin bags?
Yes. Singapore Airlines weighs carry-on baggage at check-in, and enforcement is active on many routes, especially out of Changi. The limit is 7 kg for the cabin bag. If you’re over, you’ll be asked to check the bag, move items into your hold luggage, or carry things on your person.
