Who This Guide Is For

This guide is useful if you are:

• Flying Singapore Airlines for the first time
• Travelling with cabin baggage only
• Unsure about the 7 kg cabin baggage limit
• Carrying a laptop, power bank, or personal item
• Travelling with an infant or musical instrument
• Connecting to another airline on the same itinerary

Quick Answer

Singapore Airlines allows one cabin bag up to 7 kg for Economy and Premium Economy passengers. Business Class, First Class, and Suites passengers can carry two cabin bags, with each bag weighing up to 7 kg. Every cabin bag must stay within 115 cm (length + width + height), and passengers can also bring one small personal item, such as a handbag or laptop bag.

This guide explains cabin baggage size and weight limits, personal item rules, restricted items, travel class differences, and practical packing tips to help you avoid problems at the airport.

Singapore Airlines Cabin Baggage Allowance at a Glance

Your cabin baggage allowance depends on the cabin you’re travelling in.

Cabin Class	Cabin Bags Allowed	Weight Limit	Maximum Size
Economy	1	Up to 7 kg	115 cm (L+W+H)
Premium Economy	1	Up to 7 kg	115 cm (L+W+H)
Business Class	2	Up to 7 kg each	115 cm each
First Class	2	Up to 7 kg each	115 cm each
Suites	2	Up to 7 kg each	115 cm each

In addition to these cabin bags, passengers can usually carry one personal item that fits under the seat in front of them.

Good to know: Unlike many airlines, Singapore Airlines does not increase the weight limit for premium cabins. Instead, Business, First, and Suites passengers receive an extra cabin bag, while the 7 kg limit per bag stays the same.

How Big and Heavy Can Your Cabin Bag Be?

Your cabin bag must meet both the size and weight limits.

Cabin bag size

The total dimensions of your bag must not exceed 115 cm, including wheels, handles, and side pockets.

A cabin bag measuring around 56 × 36 × 23 cm fits within this limit and is commonly accepted on Singapore Airlines flights.

Cabin bag weight

Each cabin bag can weigh up to 7 kg.

Singapore Airlines is known for checking cabin baggage more carefully than many airlines, especially on international flights. Your bag may be weighed at check-in or before boarding, so it’s best to check the weight before leaving home.

Simple packing tip

Before travelling:

• Measure your bag with the wheels and handles included.
• Weigh it after packing, not when it’s empty.
• Use a lightweight suitcase to make the most of your allowance.

What Can You Bring Besides Your Cabin Bag?

Along with your cabin bag, you can usually carry one small personal item.

Common examples include:

• Handbag or purse
• Laptop bag
• Small backpack
• Briefcase
• Small tote bag

The personal item should fit comfortably under the seat in front of you. If it’s too large and needs to go into the overhead locker, airline staff may count it as part of your cabin baggage allowance.

For most travellers, using a laptop bag or handbag as the personal item is an easy way to keep travel documents, electronics, and valuables within reach during the flight.

Does Your Travel Class or KrisFlyer Status Change the Allowance?

Your travel class affects how many cabin bags you can bring, but not the size or weight of each bag.

• Economy and Premium Economy: One cabin bag up to 7 kg.
• Business, First, and Suites: Two cabin bags, each up to 7 kg.

If you’re a KrisFlyer Elite or PPS Club member, your cabin baggage allowance generally stays the same. Elite status usually provides extra checked baggage benefits, not additional cabin baggage.

If you regularly travel with more luggage, it’s worth checking your checked baggage allowance rather than expecting a higher cabin baggage limit.

What Can and Can’t Go in Your Cabin Bag?

Most everyday travel items are allowed in your cabin baggage, but some items are restricted for safety reasons.

Liquids

Liquids, gels, creams, and aerosols should be in containers of 100 ml or less. All containers must fit inside one clear, resealable plastic bag, following international airport security rules.

Batteries and Electronics

Power banks and spare lithium batteries should be packed in your carry-on baggage, not in checked luggage. Keep electronic devices easily accessible, as airport security may ask you to remove them during screening.

Restricted Items

The following items are generally not allowed in cabin baggage:

• Sharp objects
• Flammable materials
• Fireworks and explosives
• Weapons or realistic replicas
• Dangerous chemicals

If you’re carrying medication or medical equipment, keep it in your cabin bag along with any supporting documents you may need during security checks.

Can You Carry Baby Items, Musical Instruments, or Special Items?

Yes. Singapore Airlines allows some special items in the cabin, but they must meet the airline’s size and safety requirements.

Travelling with an Infant

If you’re travelling with an infant, you can usually carry essential baby items in addition to your own cabin baggage.

These may include:

• Baby food and infant formula needed during the journey
• Diapers and baby essentials
• A small, collapsible stroller (subject to size restrictions and airport procedures)

If your stroller is too large for the cabin, it may need to be checked at the airport or boarding gate.

Musical Instruments

Small musical instruments, such as a violin, may be carried in the cabin if they fit within the cabin baggage size and weight limits.

For larger instruments like a cello, you may need to purchase an extra seat. Contact Singapore Airlines before your trip if you’re travelling with a valuable or oversized instrument.

Do Connecting Flights Follow the Same Cabin Baggage Rules?

Not always.

If your entire journey is operated by Singapore Airlines, the same cabin baggage allowance generally applies throughout your trip.

However, if part of your itinerary is operated by another airline, especially on a codeshare flight, that airline may have different carry-on rules.

Before travelling:

• Check which airline operates each flight.
• Compare cabin baggage rules if you’re flying with more than one airline.
• Follow the stricter allowance if the rules are different.

This can help you avoid unexpected baggage issues during your journey.

What Happens If Your Cabin Bag Is Too Heavy or Too Large?

If your cabin bag exceeds the permitted size or weight, Singapore Airlines may ask you to check it into the aircraft hold.

Depending on your fare and route, additional baggage charges may apply.

Generally, this is what happens:

1. Your bag may be weighed or measured at check-in or the boarding gate.
2. If it exceeds the limit, staff will ask you to check it in.
3. Any applicable excess baggage charges may be collected.
4. You’ll board with only the items that meet the cabin baggage rules.

Because Singapore Airlines is known to check cabin baggage carefully, it’s best to weigh and measure your bag before leaving for the airport.

If your cabin bag needs to be checked, our Singapore Airlines Baggage Fees guide explains checked baggage allowances and excess baggage charges. 

Common Carry-On Mistakes

Many passengers experience delays or unexpected charges because they:

• Forget that wheels and handles count toward the total size limit
• Pack too much and exceed the 7 kg weight allowance
• Place power banks or spare batteries in checked baggage instead of the cabin
• Carry a personal item that is too large to fit under the seat in front
• Assume partner or codeshare airlines follow the same cabin baggage rules

Smart Packing Tips for Singapore Airlines Flights

Packing carefully makes it much easier to stay within the 7 kg cabin baggage limit.

Here are a few practical tips:

• Choose a lightweight cabin suitcase.
• Wear heavier shoes or jackets instead of packing them.
• Place laptops, chargers, medicines, and valuables in your personal item.
• Use packing cubes to organize your belongings.
• Weigh your bag at home with a luggage scale.
• Keep liquids in a clear resealable bag for faster security screening.
• Leave a little extra space in your bag in case you buy duty-free items after security.
