- 4 min read
Packing aerosols for a British Airways flight can be confusing. Many travellers assume sprays aren't allowed in hand luggage, while others believe any aerosol is acceptable provided the can is only partly full. Neither assumption is quite right.
The good news is that aerosols are permitted in hand luggage on British Airways flights, provided they comply with airport security liquid restrictions.
Understanding the rules before you travel can help you avoid delays at security and ensure your favourite travel toiletries arrive with you.
Many British Airways passengers travelling with cabin baggage choose travel-sized toiletries to make packing quicker and more convenient. Aerosol products are among the most commonly packed items alongside toothpaste, shampoo, deodorant, moisturiser and sun cream.

Which Aerosols Can You Take on British Airways?
Most everyday aerosol toiletries are permitted provided they comply with airport security rules.
Common examples include:
Spray deodorant
Hairspray
Shaving foam
Body spray
Spray sun cream
Dry shampoo
Always check the size of the container before travelling.
Does a Half-Used Aerosol Count?
Yes.
This catches many travellers out.
Airport security checks the maximum capacity printed on the can, not how much product is left inside.
A half-used 150ml deodorant is still treated as a 150ml container and may be removed during security screening.
The safest option is to travel with aerosols that are clearly marked 100ml or less.
Are Aerosol Deodorants Allowed on British Airways?
Yes.
Spray deodorants are allowed in hand luggage provided the container complies with airport liquid restrictions.
Remember that aerosol deodorants count towards your liquids allowance alongside toothpaste, shampoo, mouthwash and other liquid toiletries.
New UK Airport Security Scanners
Some UK airports now use next-generation security scanners which allow passengers to leave liquids inside their bags.
However, not every airport has completed the upgrade, and your return airport may still apply the traditional 100ml rules.
Unless you've confirmed the arrangements for both airports, it's safest to continue travelling with containers of 100ml or less.
What About Hairspray and Dry Shampoo?
Hairspray and dry shampoo follow the same airport security rules as other aerosols.
The important points are:
The container should normally be 100ml or less.
Larger cans belong in checked baggage.
Aerosols count towards your liquid allowance.
Container size matters more than how much remains inside.
Common Aerosol Packing Mistakes
Many travellers run into avoidable problems because they:
Pack half-used aerosols larger than 100ml.
Assume aerosols are exempt from liquid restrictions.
Forget that spray sunscreen counts as an aerosol.
Carry multiple aerosols which quickly use their liquids allowance.
Leave toiletries loose rather than organised together.
Preparing your toiletries before travelling helps make airport security much smoother.
