What Can You Bring on a Plane: The Complete Guide

Air travel comes with a set of strict rules regarding what you can and cannot bring in your carry-on luggage. Many travellers experience delays at security checkpoints due to confusion about permitted items. Being informed will not only speed up your screening process but also help prevent the frustration of having to discard belongings at the airport. Our latest guide will bring you up to speed with all essential carry-on luggage restrictions and provide expert tips on how to pack efficiently.
What Can You Bring on a Plane?
Airport security personnel are strict about their regulations and failing to comply can result in the confiscation of prohibited items. Below is an in-depth breakdown of what is allowed in your carry-on luggage.
Liquids
Passengers can bring liquids in their hand luggage, but they must follow the 100ml rule. This means all liquids must be placed in containers no larger than 100ml and fit inside a transparent, resealable plastic bag with a 1-litre capacity. If your liquid items do not meet these regulations, they will be discarded at security.
Expert Tip: Security checks often require you to remove your liquids from your luggage for inspection. Keep them in an easily accessible compartment for a faster screening process. Our flight experts also recommend buying travel-sized versions of your essentials to meet the carry-on luggage liquid restrictions.
Toiletries / Cosmetics
Common toiletries like deodorants, toothpaste, and shampoo must adhere to the 100ml limit. Solid toiletries, such as bar soap, deodorant sticks, or powder-based products, are not subject to liquid restrictions.
What cosmetics can you bring on a plane? No one will stop you from bringing any cosmetics but there are certain guidelines. Makeup items like liquid foundation and mascara are considered liquids and must be included in your transparent bag.
Expert Tip: Consider using solid alternatives like shampoo bars and powder-based cosmetics to bypass liquid restrictions and make packing easier.
Tools
Small personal tools like tweezers and nail clippers are usually allowed in the hand luggage. However, sharp objects like large scissors (over 4 inches) and box cutters are strictly prohibited.
Medication
Prescription medications are permitted even if they exceed 100ml. SkyRefund experts recommend carrying a doctor’s note or prescription, especially for liquid medications or medical syringes.
Expert Tip: Always pack essential medications in your carry-on in case your checked baggage is lost or delayed. Our experts also recommend storing them in their original packaging for hassle-free security checks.
Matches/Lighters
One lighter per passenger or a box of safety matches is allowed but must be kept in one of your pockets or your jacket, not in your carry-on.
Electronics
Laptops, tablets, cameras, and e-readers are allowed in carry-on luggage. Power banks and lithium batteries above 100Wh must be carried in the cabin, as placing them in checked luggage poses a fire risk.
Baby Items
Parents travelling with infants are allowed to bring baby formula, milk, and baby food, even if the packaging exceeds the standard 100ml restriction. Security may require you to open containers for screening.
Strollers and car seats can usually be taken on board or checked at the gate.
E-Cigarettes
E-cigarettes and vaping devices are allowed in your hand luggage but cannot be used on the plane. Spare batteries should be stored in protective cases to avoid fire hazards.
Razors
Razors can be a confusing item when it comes to air travel restrictions.
- Disposable razors - Allowed.
- Electric razors - Allowed.
- Cartridge razors - Allowed.
- Straight razors and safety razors with removable blades - Not allowed in carry-on luggage. These must be packed in checked luggage due to the potential safety risk posed by exposed blades. You can, however, carry a safety razor without a blade.
Expensive Items
Items such as jewellery, expensive watches, designer handbags, high-end electronics, and wedding dresses should never be placed in checked luggage due to the risk of loss or damage. Airlines are not responsible for the loss of valuable personal items and compensation for lost or stolen valuables is often limited.
Additionally, delicate items like musical instruments and fragile collectables should be properly packed and, where possible, carried in the cabin. Some airlines allow passengers to book an extra seat for particularly large or fragile valuables, such as artwork or expensive photographic equipment.
Expert Tip: Consider purchasing additional travel insurance for extra protection if you’re travelling with high-value items. SkyRefund flight experts also suggest keeping receipts or appraisals for expensive belongings in case you need to file a claim.

What Can’t You Bring on a Plane?
Understanding prohibited items is essential to avoid last-minute hassles at security checkpoints. Here are some of the main categories:
Sharp Objects
Items such as knives, box cutters, and razor blades are not permitted in carry-on luggage. Small scissors with blades shorter than 4 inches (measured from the pivot point) are generally allowed.
Sports Equipment
Most sports equipment is prohibited in carry-on luggage because of its potential use as a blunt weapon. Items such as baseball bats, golf clubs, and hockey sticks must be checked in.
Large Liquid Items
Passengers are not allowed to carry liquids exceeding 100ml per container in their hand luggage. This includes beverages, soups, lotions, and even certain foods like yoghurt or jelly.
Firearms and Explosives
Firearms, ammunition, and any explosive materials are strictly forbidden in carry-on luggage. Passengers travelling with firearms for legal purposes must check with their airline and comply with all necessary documentation and security protocols for checked baggage transport.
Size and Weight Restrictions on Carry-On Luggage
Aside from what you can take on a plane, it's good to know what are the size and weight restrictions for carry-on luggage. While exact sized may vary they follow the same principles which we outline below.
What Size Bag Can You Bring on a Plane?
Each airline has its own specific size restrictions for carry-on baggage. Most airlines allow one main cabin bag and one smaller personal item. However, budget airlines tend to enforce stricter size policies and may charge extra for a larger bag that exceeds their dimensions.
Additionally, airline staff may require passengers to place their hand luggage in a size-measuring frame at the boarding gate. It may need to be checked in at an additional cost if it does not fit within the required dimensions.
Expert Tip: If your carry-on bag is close to the airline’s size limits, opt for soft-sided luggage instead of a rigid suitcase. A slightly overstuffed soft bag can often be adjusted to fit within the required size dimensions.
Weight Restrictions for Carry-On Luggage
Most airlines impose weight limits of 7-10 kg. Budget airlines often enforce stricter policies.
Expert Tip: Weigh your hand luggage at home to avoid surprise fees at the airport. Some airlines charge steep penalties for exceeding weight limits.
