Passengers flying from Kenya often encounter the familiar question at airport security: how much liquid can you actually take onto the aircraft?
Liquids, aerosols and gels are subject to aviation-security controls because liquid explosives remain an aviation-security concern. ICAO says its current security-control guidelines for liquids, aerosols and gels should continue to be implemented until suitable screening technology allows those restrictions to be replaced. ICAO
For passengers using JKIA and other Kenyan airports, the practical rule is to prepare cabin liquids around the 100 ml-per-container limit, while remembering that medicines, baby food and other essential liquids may qualify for exemptions.
This article forms part of the Metros Kenya Airport Rules in Kenya: Passenger Laws, Security Rules and Traveller Guide.
What Is the 100 ml Liquid Rule?
ICAO’s security-control guidance provides that liquids carried through passenger screening should be in containers with a capacity of no more than 100 ml.
The containers should then fit comfortably inside a transparent, resealable plastic bag with a maximum capacity of one litre, with one such bag permitted per passenger. ICAO
This means the restriction applies to the capacity of each container, not simply the amount of liquid remaining inside it.
A 200 ml bottle containing only 50 ml of liquid, for example, does not satisfy the standard 100 ml container rule under ICAO guidance. ICAO

What Counts as a Liquid?
The aviation definition is broader than many passengers expect.
ICAO’s liquids, aerosols and gels—or LAGs—guidance includes products such as:
- water and other drinks;
- soups and syrups;
- sauces and pastes;
- creams and lotions;
- cosmetics and oils;
- perfumes;
- sprays;
- hair and shower gels;
- shaving foam;
- deodorant aerosols;
- toothpaste;
- mascara;
- lip gloss; and
- other products with a similar consistency. ICAO
So a traveller should not interpret “liquid” as meaning only water or drinks.
Can You Carry Several 100 ml Bottles?
Yes, subject to the overall security requirements.
ICAO’s guidance provides for individual containers of up to 100 ml to be placed inside a single transparent resealable bag of up to one litre. The containers should fit comfortably and the bag should close completely. ICAO
This means the rule is not simply “you can carry only 100 ml in total.”
Instead, individual containers must satisfy the size restriction and collectively fit within the permitted bag.
Can You Carry a Half-Full Bottle Larger Than 100 ml?
This is one of the most commonly misunderstood parts of the rule.
Under ICAO guidance, a container larger than 100 ml should not be accepted merely because it is partly empty. ICAO
For example, putting 50 ml of shampoo into a 250 ml bottle does not turn it into a 50 ml container for security purposes.
If you want to take shampoo, lotion or another ordinary liquid into the cabin, use an appropriately sized travel container.
Can You Take Drinking Water Through Security?
An ordinary bottle of water is a liquid and therefore falls within liquids-screening controls.
ICAO specifically includes water and other drinks within its definition of LAGs. ICAO
Passengers should therefore not assume that a normal full-size bottle of water can be carried through a checkpoint simply because it is unopened.
What passengers can purchase or obtain after security is a separate matter.
What About Medicine?
There are important exemptions.
ICAO guidance allows exemptions for liquids needed during a journey for essential medical purposes. Security personnel may require appropriate verification of the liquid and why it is necessary. ICAO
Liquid medicine exceeding 100 ml can therefore be treated differently from ordinary toiletries.
Passengers carrying substantial quantities of liquid medication should keep the medicine identifiable and carry supporting documentation where appropriate.
Do not pour important medication into an unidentified container if that can reasonably be avoided.
What About Baby Milk and Baby Food?
ICAO’s guidance also provides exemptions for baby milk, baby food and special dietary requirements. ICAO
Security may still need to establish that the liquid is legitimate.
Parents should therefore allow sufficient time for screening when travelling with baby formula, milk or other essential liquid foods.
Can You Carry Perfume?
Perfume falls within the liquids restrictions.
For ordinary cabin baggage, passengers should therefore prepare perfume bottles according to the applicable liquids-security requirements.
There is, however, an important distinction for products purchased from airport duty-free shops.
ICAO’s security framework provides for security tamper-evident bags—often called STEBs—to facilitate the carriage of qualifying liquids purchased at airports or aboard aircraft, including for transfer passengers. ICAO
Keep the item sealed as required and retain proof of purchase.
Be Careful When Connecting Through Another Airport
Connecting passengers need to be particularly careful.
Even if a liquid was accepted at the airport where your journey began, you may encounter another security screening point during your connection.
ICAO developed security tamper-evident bags partly to address this problem for liquids bought at airport retailers or aboard aircraft and subsequently carried by transfer passengers. ICAO
The transit country’s security requirements can therefore matter.
Passengers making international connections should check the rules for both their departure and transit airports.
Are Liquids in Checked Baggage Subject to the Same 100 ml Rule?
The familiar 100 ml security restriction concerns carry-on liquids passing through passenger security screening.
Checked baggage is different.
However, that does not mean every liquid can automatically be placed in checked luggage.
Some liquids, aerosols and other substances are classified as dangerous goods because they may be flammable, toxic, corrosive or otherwise hazardous.
KCAA explains that some dangerous goods are prohibited on aircraft entirely, some require specific approvals, some are restricted to cargo aircraft, and others can be transported on passenger aircraft when applicable requirements are met. Kenya Civil Aviation Authority
So passengers need to distinguish between the 100 ml security rule and dangerous-goods restrictions.
Toiletries and Aerosols Can Have Additional Limits
Certain medicinal and toiletry articles have dangerous-goods quantity limits separate from the 100 ml cabin-security rule.
International dangerous-goods guidance, for example, provides allowances for certain medicinal or toiletry articles and qualifying aerosols while imposing overall and per-item quantity limits. ICAO
This illustrates why a product can be subject to more than one rule at the same time.
Aerosol deodorant, for example, may have to satisfy both aviation-security requirements for cabin baggage and dangerous-goods requirements governing aerosols.
Security Rules and Dangerous-Goods Rules Are Different
This distinction is central to understanding airport baggage rules.
A bottle may be restricted at the passenger checkpoint because of aviation security, even though its contents are not inherently dangerous.
Another substance may be restricted because it presents a fire, chemical or other safety hazard aboard an aircraft.
KCAA regulates dangerous goods transported by air and relies on the ICAO Technical Instructions as part of that framework. Kenya Civil Aviation Authority
The same distinction appeared in our guide Can You Carry a Power Bank on a Plane in Kenya? Battery Rules Explained, because lithium batteries are primarily regulated because of the safety risk they can present during air transport.
What Happens If Your Liquid Does Not Pass Security?
If a passenger presents an ordinary liquid that does not satisfy the applicable security requirements, they may have to remove or dispose of it before proceeding through security.
Kenyan air-travel security guidance has specifically instructed passengers to avoid carrying liquids, gels and aerosols above recommended quantities and notes that passengers may be directed outside the security area to remove prohibited items before their baggage is resubmitted for screening. Kenya Civil Aviation Authority
Passengers should therefore check their cabin baggage before arriving at the airport.
How to Pack Liquids for a Flight From Kenya
For ordinary cabin toiletries and other non-exempt liquids, the safest approach is to use containers no larger than 100 ml and place them in a transparent resealable bag of no more than one litre.
Keep essential medication identifiable and bring supporting information where appropriate.
Parents travelling with baby milk or food should keep those items accessible for security inspection.
Duty-free liquids should remain in the appropriate tamper-evident packaging when required, particularly when connecting through another airport.
And if the substance is flammable, corrosive, toxic or otherwise potentially hazardous, check dangerous-goods requirements rather than assuming the ordinary liquids rule is sufficient.
The Bottom Line
For passengers travelling from Kenyan airports, the practical cabin-baggage standard is containers of no more than 100 ml, placed in a transparent resealable bag of up to one litre, subject to applicable exemptions. ICAO’s guidance specifically provides exceptions for essential medication, baby milk and food, and special dietary requirements. ICAO
A container larger than 100 ml should not be assumed acceptable merely because it contains less than 100 ml of liquid.
Passengers should also remember that security restrictions on liquids are different from dangerous-goods rules. Some substances may remain restricted regardless of container size because of what they contain. Kenya Civil Aviation Authority
