What NOT to Pack in Your Carry-On Bag

Liquids over 100ml

The liquids restriction is pretty universal nowadays, though enforcement may vary. To be on the safe side, stick to the rule: all liquids must be in containers of no more than 100ml, and all containers must fit in a clear, one litre sized zip top plastic bag. There are special rules for medications, but these vary by country.

What toiletries can you take on a plane?

You can take toiletries or other liquids that are in containers no larger than 100ml, and they must all fit in a one litre clear zip top bag. This includes liquids, gels, and aerosols.

Sharp objects

This one should be self-explanatory, but sharp objects are prohibited in carry-on luggage because they could be used as a weapon. If you simply must bring a sharp object on your trip, it must be packed in your checked luggage. Straight razors are also not allowed in your carry-on luggage. However, you can take a razor through security if it’s a safety razor. That means the actual blade is attached to a handle, like the kind most of us use to shave.

Sporting equipment

If playing sports will be part of your travels, consider renting equipment at your destination. If you’re quite attached to using your own sports equipment, you’ll probably need to check it.


Obviously a gun is a weapon, and they don’t want you bringing it on an airplane in your carry-on bag. Most guns are permitted in checked luggage as long as they are empty, and they must be in a locked, hard-sided container.

Self-defense items

Self-defense items, like pepper spray or mace, are not allowed in carry-on luggage. These could be considered a weapon, so leave them at home.

Lighters, matches and other flammable items

If you feel you must have flammables on your vacation, buy them when you arrive. Lots of camping gear, like camping stoves, is considered flammable as well. Check the airline for rules and restrictions. If possible, get the equipment you need once you arrive to avoid the hassle.

Meat, fruit, vegetables, and other agricultural products

When traveling internationally, most countries prohibit you from bringing in meats, fruit, vegetables, plants, and other agricultural products. If you want to bring an apple as a snack, just make sure you eat it on the plane.

Nail polish

Ok, bring the nail polish (in your liquids bag) if you want, but please don’t paint your nails in flight. This falls under the disrespectful smell category.

Adult viewing and reading materials

Your neighbour does not want to look over and see you reading an adult magazine or watching adult movies on your laptop. Save it for the privacy of your own home.


We’re all glad you care about how you smell, but perfume can be unpleasant and bothersome to many people. Some are even allergic. Wait until you reach your destination to spray on the perfume, that way your seatmates can breathe easy during the flight.
