Packing is one of the most tedious parts of preparing for a trip abroad, especially figuring out what you can carry on and what must go in checked baggage. I’ve been confused many times, so this time I checked properly using Korea’s Aviation Security 365 website.
Checking Prohibited Items on Aviation Security 365
Aviation Security 365 is a service that tells you in advance which prohibited items you can’t take on board. You can see at a glance what’s not allowed in the cabin, and it helped a lot before our departure.

Prohibited Items Caught at Airports
In 2023, a staggering 5.25 million prohibited items were confiscated at 15 airports in Korea. That’s a lot of travelers caught out by not knowing the rules. I’ve had things confiscated a few times myself, but this time checking ahead meant no trouble.


Confusing Items: Power Banks, Lighters and Liquids
If power bank, lighter and liquid rules confuse you, Aviation Security 365 makes them easy to check. As of 2024, only power banks up to 160 Wh could be carried on, you could bring one lighter, and liquids had to be in containers of 100 ml or less in a clear zip bag.

Why Checking Before You Fly Matters
Checking prohibited items on Aviation Security 365 before departure gives real peace of mind. I checked ahead this trip and wasn’t caught off guard at the airport.


Items to Watch Out For
Hiking poles and multi-tools like Swiss Army knives can’t be carried on either, so be sure to pack them in checked baggage.


Why Aviation Security 365 Is Useful
Knowing prohibited items in advance saves you from losing valued belongings and wasting time at the airport.


Voluntary Aviation Security Reporting
Aviation Security 365 also runs a voluntary reporting system where anyone can report aviation security risks or inconveniences. Reporters are legally protected, and experts analyze reports to improve aviation security.

Rules for Common Prohibited Items
Here are some rules worth knowing before departure, based on Aviation Security 365 guidance as of 2024. Always check your airline and destination country rules too.
- Firearms: can be checked if you show the airline your permit, separate the ammunition and pack them in a hard locked case.
- Knives: blades of 6 cm or less were listed as allowed in carry-on.
- Power banks: up to 100 Wh, five per person; over 100 Wh up to 160 Wh, two per person with airline approval; over 160 Wh, not allowed.
- Liquids: containers of 100 ml or less, in one clear 1-liter zip bag per person.
