Since 2006 there have been restrictions placed on the carrying of liquids in carry-on flight baggage.
The move to restrict the carrying of liquids on flights was implemented as a reaction to terrorist activity.
Despite the threat level varying from year to year, it seems that restrictions on carrying liquids in your cabin baggage are here to stay.
What are the rules, restrictions and allowances for liquids on flights?
Broadly speaking, most of the major airlines and countries have implemented similar liquid restrictions. This is a sensible move aimed to reduce confusion where many airlines use the same airport, and consequently share the same airport security screening facilities. It is also less confusing for passengers on international flights knowing that the cabin baggage liquid restrictions will be broadly the same for their outward and return journeys.
The basic rules are:
- All liquids that you bring to the airport in your carry-on baggage must be in containers no larger than 100ml or 3.4oz
- All liquid containers in your cabin baggage must be kept in a clear plastic resealable bag for inspection or screening at airport security
- Only one clear plastic bag of liquid containers may be carried per passenger travelling
Each airline provides specific guidance on the 100ml liquid restrictions so it important to check their instructions.
Common questions about liquids on flights
Q. Do these rules also apply to checked baggage in the aircraft hold?
A. No. The 100ml or 3.4oz liquid restrictions only apply to your carry-on baggage.
Q. What about liquids I buy at the airport?
A. The liquid restrictions apply to all liquids in your possession when you go through airport security. Any liquids you purchase after passing through security are allowed. In some cases duty free bottles may have to be placed in sealed bags, but they can still be carried on the flight.
Q. What counts as a liquid?
A. Any fluid of any kind is counted as aa liquid for these cabin baggage restrictions. This also includes pastes, gels, lotions, creams, sprays or aerosols. If in doubt, leave it out.

Drinks, perfume, aftershave, deodorant, toothpaste, shampoo, shower gel, shaving cream or gel, toiletries, cosmetics, hand cream, liquid foodstuffs or condiments, sun tan lotion, after sun products, hairspray, contact lens solution and much more.
Q. Are there exemptions for baby milk or medecines?
A. Yes. You can carry an amount of baby milk larger than 100ml if it will be required on the flight. Liquid medecines larger than 100ml are generally allowed in cabin baggage but you may need a doctor’s letter or a copy of your prescription.
