31 things that are not allowed in carry on

Airlines seem to be charging more and more for checked bags so these days many people are choosing to travel by air with just a carry on bag.

It is quite surprising what you can get in a small bag but it is obviously important to know what items are not allowed in carry on so you don’t run into problems at airport security.

Generally the restrictions on what can be carried in carry on are more rigorous than checked bags. Much of what you cannot take in your hand luggage is pretty much common sense, at least for most people. But there are a few surprises so you need to ensure you don’t have these in your bag.

The most common things you cannot take in carry on bags

Liquids

Liquids over 3.2 ounces (100ml) is an important one to remember. You cannot take any individual liquids, or to be more accurate, any liquids container larger than 3.2 ounces in carry on, even if the container has less liquid in it than 3.2 ounces. All liquids must be carried in a one quart-sized see-through resealable bag with only one allowed per passenger.

So just traveling with carry on means that any toiletries you may want to take with you have to meet these size restrictions so beware.

Some things which you might not consider to be a liquid are also treated as liquids under these rules so I have written a detailed article on this which I suggest you read – Maximum liquid permitted in carry on on a plane. TSA 3-1-1 liquids rule.

Extra lighters and matches

If you smoke then you cannot take more than one lighter or one box of safety matches on board, whether in your carry on or in your pocket.

You cannot take “strike anywhere” matches in carry on (or in checked baggage).

You cannot take torch lighters which pipe smokers sometimes use on board either.

Strong alcohol

Any alcoholic beverage with more than 70% ABV (alcohol by volume) also known as 140 proof cannot be carried either in carry on or checked bags.
