Can You Take Aerosols In Hold Luggage? Find Out Here!

Are Aerosols Allowed In Hold Luggage?

Many people wonder whether or not you can take aerosol cans on holiday with you, or if they are at risk of exploding in the passenger cabin due to the pressurised air. 

Luggage aerosols can be taken in your hold luggage with no issues as long as you do not take more than 2 litres of aerosols per person and each aerosol can is not any bigger than 500ml per can, for hand luggage, your aerosol can have to be less than 100ml travel size. 

To figure out what type of aerosols you can take in your hold luggage and the rules for packing them, we have composed a guide below with everything you need to know about taking aerosols when travelling. 

Rules For Packing Aerosols In Your Hold Luggage 

Compared to the older times, travelling with aerosols in your checked luggage is a lot easier than it used to be and many airlines prefer you to pack your larger aerosols into your hold bag rather than your carry-on baggage. 

Every aerosol in your checked bag should have a lid to prevent it from leaking, if not then the aerosol could potentially be removed during airport security checks. The general rules for aerosol toiletries are the same for each person airline wise, you are allowed around 4 cans of aerosol per person and individual containers for the aerosols should be no more than 500ml each. 

You are not allowed to carry any more than 2 litres of aerosols per person in your checked bag. Airport scanners have the right to remove excess aerosols from your luggage if need be. To minimise the number of aerosols you pack in your checked luggage you can try using alternatives such as gels, creams or deodorant sticks if needed. 

Some people might assume if you have two checked bags on your flight voucher then you can bring up to 40 litres of aerosols per person, but the rule is per person airline, so you still have to abide by 20 litres. 

Never try and pack flammable aerosols in your checked luggage as they are among restricted baggage items and will be removed, stick with medical aerosols and toiletry aerosols only. 

Rules For Packing Aerosols In Your Hand Luggage

If you would like to pack some aerosols in your hand luggage then you will be more limited on baggage measures, in carry-on baggage you are allowed liquids in containers up to 100ml, and aerosols do fall under this category, larger containers are not permitted in your carry-on luggage. 

As to how many aerosols you want to pack in your carry-on baggage is down to you, each person airline wise gets one quart-sized plastic bag each, so as long as your aerosols fit into this bag and it seals, then it will be allowed within the cabin hand luggage allowances. 

There are a few exceptions to this 100ml rule person airline wise, for example, if you have to carry inhalers over 100ml then this may be allowed in carry-on baggage, also if you need to take oxygen cylinders this might be allowed and breast milk as a liquid is allowed in larger quantities.

Aerosols in your carry-on baggage which are bigger might be removed by the airline before travel and you should always avoid packing flammable aerosol's in your luggage too.

Can Aerosols Explode In Checked Baggage? 

The types of toiletry aerosols which are allowed in checked baggage on a plane will likely not explode in the carriage in the aircraft cabin, although it is possible, the conditions inside of a plane are not likely to trigger an explosion, hence why there are allowed. 

More flammable aerosols however are not okay to bring in your hold luggage as there is a higher chance of them exploding. 

In the event of an aerosol exploding in your hold luggage, this would likely be triggered by something else overheating in the bag such as a battery container.

We have listed some other reasons as to why an aerosol might explode in your hold luggage below and why it is unlikely to happen inside an aircraft. 

Decompression 

Decompression can cause an explosion in an aerosol can if the pressure change outside to inside where the can becomes substantial, this is highly unlikely even if the pressure was to drop inside of the aircraft cabin, so should not be a cause for concern.

Heat 

If your aerosol is to get hot enough, the pressure inside the can might eventually build up and the structure of the can will not be able to cope, leading to an explosion, once again, very unlikely during the aircraft where it is temperature-controlled. 

Pressure 

When flying, an aeroplane has a lower pressure from the airport that you took off from, some worry that this pressure change might cause the can of aerosol to pop, just the way a bag of crisps might expand during a flight, however, this is very rare as the pressure drop is typically not enough for this to happen.

Damage 

It is true that if your aerosol can happen to get damaged or punctured the then it might explode, but once again this is very unlikely to happen inside of your luggage.

Which Luggage Aerosols Are Allowed In Checked Baggage? 

Flammable aerosols such as aerosol paints are not permitted to be in your checked baggage or hold baggage, only aerosols that are used for skin contact or medical purposes are typically allowed, too see what types of aerosols you are allowed to take in your luggage, we have listed the permitted and non-permitted types below.

  • Wrap it in clothes - Take a t-shirt and wrap the aerosol inside, not only does this prevent leakage if the can does explode but it stops it from ruining your whole suitcase too.
  • Tape the lid - One way to have peace of mind about your aerosols not exploding during your flight is to keep the lid taped on, doing this prevents it from popping off mid-flight and causing leakage, some cans also have a locking mechanism which you should make sure to turn on beforehand.
  •  Store them in a bag - You need a resealable bag to pack your aerosols in your carry-on luggage, but if you can fit we would recommend doing so in your hold luggage too, this is the most fool-proof way to stop any aerosols ruining the rest of the contents in your bag and keeps everything neat.

What Else Is Restricted In Hold Luggage?

Apart from flammable aerosols, there are a few other restricted items to be aware of which you should hold off from packing in your luggage, otherwise, your luggage might be held in security and potentially opened.
