Singapore Airline Luggage Size Guide (2026)
Singapore Airlines flies from Sydney, Melbourne, Brisbane, and Perth to Singapore and onwards to more than 60 destinations across Europe, Asia, and the Americas. Its baggage policy is more generous than most, but it has one catch many travellers miss: your Economy fare type determines whether you get 25 kg or 30 kg checked. Book a Value or Lite fare and you are 5 kg behind before you have started packing.
This guide covers carry-on dimensions, checked baggage by fare and cabin, KrisFlyer tier allowances, packing weights in real terms, and the right suitcase size for every trip type. All figures are sourced directly from singaporeair.com.

Carry-On Baggage Rules
The direct answer: Economy and Premium Economy get one carry-on bag up to 7 kg, with total dimensions not exceeding 115 cm. Business, Suites, and First get two bags at 7 kg each. All cabins may also carry one personal item free of charge.
| Cabin | Allowance | Personal item |
|---|---|---|
| Suites, First, Business | 2 bags, 7 kg each. Max 115 cm total per bag | Yes - max 40 x 30 x 10 cm (80 cm total) |
| Premium Economy | 1 bag, 7 kg. Max 115 cm total | Yes - max 40 x 30 x 10 cm (80 cm total) |
| Economy (all fares) | 1 bag, 7 kg. Max 115 cm total | Yes - max 40 x 30 x 10 cm (80 cm total) |

Does My Bag Meet the 115 cm Rule?
Singapore Airlines measures carry-on by total linear dimensions - not per-side. Add length + width + height. The result must not exceed 115 cm.
The Fare Type Problem: Why 25 kg is Not 30 kg
Singapore Airlines splits Economy into four tiers, each with a different checked baggage allowance. The gap between the cheapest and most flexible Economy fare is 5 kg - on a long-haul trip to London or Frankfurt, that is the difference between a comfortable bag and one that's stuffed to its limit.
| Fare tier | Booking classes | Checked allowance (ex Americas) | What it means in practice |
|---|---|---|---|
| Flexi | Y, B, E | 30 kg | Fully changeable - usually the most expensive |
| Standard | M, H, W | 30 kg | Mid-range fares - the most commonly booked |
| Value | Q, N | 25 kg | Discounted, less flexible - often listed on comparison sites |
| Lite | V, K | 25 kg | Cheapest Economy - least flexible, lower checked allowance |
Your booking class is on your e-ticket or visible in Manage Booking on singaporeair.com. If you see Q, N, V, or K next to Economy, your checked allowance is 25 kg, not 30 kg.
Checked Baggage in Full
Singapore Airlines uses two systems depending on your destination. The weight concept covers all routes except Canada and the USA - you can check as many bags as you need, provided combined weight stays within your allowance and no single bag exceeds 32 kg. The piece concept applies to Canada and USA routes.
Weight Concept - All Routes Except Canada and USA
| Cabin / Fare | No status | Elite Silver | Elite Gold / SA Gold | PPS Club |
|---|---|---|---|---|
| Suites / First | 50 kg | 60 kg | 70 kg | 100 kg |
| Business | 40 kg | 50 kg | 60 kg | 80 kg |
| Premium Economy | 35 kg | 45 kg | 55 kg | 70 kg |
| Economy Flexi / Standard | 30 kg | 40 kg | 50 kg | 60 kg |
| Economy Value / Lite | 25 kg | 35 kg | 45 kg | 50 kg |
KrisFlyer status boosts apply to Singapore Airlines-operated flights only. No single bag may exceed 32 kg.

What Does Your Allowance Actually Get You?
Your suitcase takes up part of your allowance before a single item goes in. Find your checked allowance in the left column, then read across to see how much you actually have left to pack depending on your suitcase weight.
| Your allowance | Standard large (4.5 kg case) | Lightweight large (3.2 kg case) | Premium lightweight (2.3 kg case) |
|---|---|---|---|
| 25 kg (Value / Lite) | 20.5 kg to pack | 21.8 kg to pack | 22.7 kg to pack |
| 30 kg (Flexi / Standard) | 25.5 kg to pack | 26.8 kg to pack | 27.7 kg to pack |
| 35 kg (Premium Economy) | 30.5 kg to pack | 31.8 kg to pack | 32.7 kg to pack |
| 40 kg (Business) | 35.5 kg to pack | 36.8 kg to pack | 37.7 kg to pack |
Common Item Weights
Which Suitcase for Your Trip?
The right suitcase depends on your trip length, how much you pack, and your fare type. Here are the most common scenarios for SIA passengers from Australia.
Pre-Purchasing Additional Baggage
Pre-purchasing online is always cheaper than paying at the airport. Singapore Airlines offers two discount windows - the earlier you buy, the better the saving.
| Purchase timing | Discount | AUS rate per kg (Band 3) |
|---|---|---|
| More than 48 hours before departure | 25% off | USD 16.50 / kg |
| Within 48 hrs - up to 6 hrs before | 10% off | USD 19.80 / kg |
| Within 6 hours / at the airport | No discount | USD 22.00 / kg |
Australia and New Zealand are Band 3. Extra weight is purchased in 5 kg blocks, up to 100 kg maximum additional per flight. KrisFlyer members receive further discounts on top of these rates.

Should You Buy Extra Baggage?
Liquids, Gels, and Powders in Your Carry-On
The international 100 ml rule applies on all Singapore Airlines flights. Every liquid, gel, aerosol, cream, or paste in your carry-on must be in a container no larger than 100 ml. All containers must fit in one transparent, resealable plastic bag with a maximum one litre capacity. One bag per passenger.
Smart Bag Rules
- Smart bags with a removable lithium battery may travel as carry-on (battery stays in bag, bag fully powered off) or as checked baggage (battery must be removed and carried in the cabin)
- Smart bags with a non-removable battery are not accepted as carry-on or checked baggage on any SIA flight
- GPS and Bluetooth trackers such as Apple AirTags are generally permitted
- Power banks must be in carry-on only - never in checked baggage
Families - Children and Infants
Children aged two and above travelling on a child fare receive the full adult baggage allowance for their cabin class. A family of four on Economy Standard fares has a combined checked allowance of 4 x 30 kg = 120 kg. Infants travelling on a lap ticket receive up to 10 kg of checked baggage. Families travelling with infants may also check one of each of the following free of charge in addition to their standard allowance:
- Category 1: One fully collapsible stroller or pushchair
- Category 2: One carry-cot or car seat
KrisFlyer status boosts do not extend to infant allowances. The 10 kg infant allowance is fixed regardless of membership tier.
Codeshare Flights and Multi-Carrier Journeys
On itineraries that include flights operated by partner airlines under a Singapore Airlines flight number, the operating carrier's baggage rules apply to that sector - not SIA's. KrisFlyer status benefits for additional baggage also apply only to Singapore Airlines-operated flights.
How Singapore Airlines Compares from Australia
Common Mistakes to Avoid
- Assuming 30 kg in Economy when booked on a Value or Lite fare (Q, N, V, K) - these include only 25 kg
- Using a carry-on bag that measures over 115 cm total - a 56 x 36 x 24 cm bag already equals 116 cm
- Carrying a laptop in a large padded backpack and expecting it to count as a personal item - the personal item must be 40 x 30 x 10 cm max per piece, and 80 cm total
- Not logging into KrisFlyer before checking additional baggage prices - members receive discounts on top of the standard pre-purchase rates
- Checking a single bag over 32 kg - Singapore Airlines will not accept it and you will need to repack before check-in
- Expecting KrisFlyer status allowances to apply on codeshare partner flights - they apply only on SIA-operated flights
- Buying extra baggage at the airport when purchasing more than 48 hours before departure saves 25%
- Packing durian in carry-on or checked baggage - it is banned on all Singapore Airlines flights
