When packing your carry-on, it’s easy to focus only on dimensions and weight to avoid extra fees. However, what’s inside is just as important. Security rules depend not only on the airline but also on the specific airport you’re flying from or to.
Keep in mind that airport security staff have the right to confiscate any item they find suspicious—even if it isn’t officially on the banned list.
Items Banned in the Cabin
Many everyday items that seem harmless are not allowed in carry-on luggage. You can usually pack them in your checked bag, but they will likely be thrown away at the security checkpoint if found in your cabin bag. These include:
- Sharp objects: Corkscrews, knives with blades over 6 cm, and large scissors.
- Pyrotechnics: Fireworks, firecrackers, flares, or party poppers.
- Flammable items: Strike-anywhere matches.
Important note on lighters: You can only take one lighter on board. It must be kept in a clear, resealable plastic bag and should be carried on your person (do not put it in your checked luggage).
Modern Scanners and the 100ml Rule
For years, we’ve been used to the 100ml limit for liquids. Today, some major airports (like London Heathrow or Birmingham) are introducing advanced scanners that allow for larger quantities of liquids.
Take note: Always check the rules of the airport you are returning from! Even if you depart from a modern terminal, your destination airport might still strictly enforce the old 100ml rule.
Exemptions to liquid limits: Regardless of the general restrictions, you can usually carry larger amounts (up to 2 liters) of essential liquids, such as:
- Medicines,
- Baby food and milk,
- Special dietary liquids. You must always declare these items to staff during security screening.
Unexpected Banned Items
Some items are strictly forbidden in the cabin for safety reasons, even if they are used for sports or work. These include:
- Sports equipment: Baseball bats, golf clubs, cricket bats, darts, and hiking poles.
- Tools: Screwdrivers, hammers, drills, or utility knives (Stanley knives).
- Martial arts gear and replica weapons: Items like nunchucks or toy guns.
The safest approach is to assume that regulations vary by country. Before you head out, take a moment to check the current guidelines for both your departure and arrival airports. It’s the easiest way to ensure a stress-free trip.
