Packing your carry-on bag sounds simple—until you arrive at the airport and discover your bag is too large or you’ve packed something that isn’t allowed. Every year, thousands of travellers pay unexpected baggage fees or have items confiscated at security.
This guide explains the most important carry-on baggage rules so you can travel confidently and avoid unnecessary costs.
What Is Carry-On Baggage?
Carry-on baggage (also called cabin baggage or hand luggage) is the bag you take into the aircraft cabin with you.
Most airlines allow:
- One cabin bag
- One small personal item (such as a handbag, backpack, or laptop bag)
However, the exact size and weight limits vary between airlines.
Common Cabin Bag Size Limits
Although every airline has its own rules, many allow cabin bags around:
- Height: 55 cm
- Width: 40 cm
- Depth: 20–25 cm
Budget airlines often have stricter rules, so always check before travelling.
Weight Limits
Some airlines don’t weigh cabin bags, while others are very strict.
Typical limits include:
- 7 kg
- 8 kg
- 10 kg
- No fixed weight limit (provided you can safely lift the bag into the overhead locker)
Liquids Rule
Airport security follows strict rules for liquids.
You can usually carry:
- Containers up to 100 ml each
- All liquids inside one clear, resealable plastic bag
- The total bag should not exceed one litre
Liquids include:
- Shampoo
- Toothpaste
- Perfume
- Sunscreen
- Makeup
- Drinks
Anything larger may be removed during security screening.
Electronics
You can normally pack:
- Mobile phones
- Tablets
- Laptops
- Cameras
- Power banks (usually in carry-on only)
Some airports may ask you to remove larger electronic devices during security checks.
Items You Cannot Carry
These items are generally prohibited in carry-on baggage:
- Large knives
- Scissors with long blades
- Fireworks
- Flammable liquids
- Tools above permitted sizes
- Self-defence sprays
Always check your airline’s guidance if you’re unsure.
Tips to Avoid Extra Charges
Follow these simple tips before heading to the airport:
- Measure your cabin bag at home.
- Weigh your bag before leaving.
- Wear heavier clothing instead of packing it.
- Keep important items in your carry-on.
- Check your airline’s baggage allowance before travelling.
Frequently Asked Questions
Can I bring food in my carry-on?
Yes, most solid foods are allowed, although liquid or semi-liquid foods may be restricted.
Can I take medication?
Yes. Essential medication is generally allowed, though airport security may ask for supporting documentation for larger quantities.

Yes, but power banks should usually be packed in your carry-on baggage rather than checked luggage.
Final Thoughts
Understanding carry-on baggage rules can save you money, reduce stress, and help you move through airport security more smoothly.
Before every trip, check your airline’s latest baggage policy and make sure your cabin bag meets both the size and weight requirements. Spending a few minutes preparing can help you avoid expensive surprises at the airport.
