Going through airport security can be one of the most stressful parts of travelling, especially if you’re unsure what you’re allowed to bring. Understanding the rules before you travel can save time, avoid delays, and prevent your belongings from being confiscated.
This guide explains the most common airport security rules and what you can expect at the checkpoint.
Liquids
One of the most important security rules involves liquids.
In most airports, liquids must:
- Be in containers of no more than 100 ml.
- Fit inside one clear, resealable plastic bag.
- Be presented separately during security screening if requested.
Liquids include:
- Water and soft drinks
- Perfume
- Toothpaste
- Shampoo
- Sunscreen
- Makeup such as foundation or mascara
If you buy drinks before security, you’ll normally have to throw them away. Drinks purchased after security can usually be taken onto the aircraft.
Electronics
Large electronic devices may need to be removed from your bag during screening.
These include:
- Laptops
- Tablets
- Cameras
- Some gaming devices
Keep them easy to access to speed up the process.
Medicines
Prescription medication is generally allowed in your hand luggage.
If you’re carrying larger quantities of liquid medication, it’s a good idea to bring a copy of your prescription or a doctor’s letter.
Always keep essential medication in your carry-on bag rather than checked luggage.
Food
Most solid foods are allowed through security.
However, foods with a liquid or gel consistency, such as soups, yoghurt, or some sauces, may be subject to the same restrictions as other liquids.
If you’re travelling internationally, remember that some countries have strict rules on bringing food across their borders.
Sharp Objects
Sharp items are usually prohibited in hand luggage.
Examples include:
- Large knives
- Box cutters
- Multi-tools with blades
- Long scissors
Pack these items in your checked baggage if permitted.
Before You Join the Queue
To get through security more quickly:
- Empty your pockets.
- Remove belts or jackets if requested.
- Have your boarding pass ready.
- Keep liquids and electronics easy to reach.
- Wear shoes that are easy to remove if required.
Common Mistakes
Many delays happen because travellers:
- Forget about water bottles.
- Leave laptops buried inside their bags.
- Carry oversized liquid containers.
- Pack prohibited items without checking the rules.
A quick check before leaving home can save you time and frustration.
Final Thoughts
Airport security exists to keep everyone safe. By knowing the rules before you travel, you can move through the checkpoint more smoothly and start your journey with less stress.
Always check your airline and departure airport for any additional requirements before your trip.
