Travellers packing drinks before security
Check the rules at your departure and transfer airports before buying 330ml cans for cabin baggage. GOV.UK says containers larger than 100ml cannot pass security at most UK airports, even when partly full.
Who is a multipack for?
Airside buyers and travellers carrying several drinks
Buying after security or departing from an airport that permits larger containers changes the security decision, but a multipack still takes up bag space. Heathrow says containers of up to 2 litres can pass through its security; check your airline’s cabin-bag allowance separately.
Shoppers choosing a drink with food
Plain still water and fruit-flavoured sparkling water are different choices. Decide whether you want fizz and flavour, then check the pack count and whether an opened can needs to close again.
What should you check before buying?
Start with the rules for every airport where you will pass through security. Then choose a pack that fits where you will drink or serve it.
| Priority | What to check | Your needs |
|---|---|---|
| Security rules | Check each departure and transfer airport’s current container limit. GOV.UK says most UK airports do not allow containers over 100ml through security; Heathrow says it permits containers up to 2 litres. | I want to take drinks through security, so I need the rule for each airport on my itinerary—not just the airport where my journey begins. |
| Drink type | Check whether the water is still or sparkling and whether fruit extracts or flavourings are listed. DASH’s mixed pack is a flavoured sparkling drink, not plain still water. | For a plain drink with food, I would choose still water. If I want fizz and fruit flavour, I can look at a flavoured sparkling pack instead. |
| Pack and closure | Compare the number and size of cans, the closure and the space available in your bag. Cano Water has separately listed ring-pull and resealable formats; Nisbets lists Radnor’s 24 x 330ml case at 8.32kg. | A large case makes more sense when I am serving several people than when I am carrying drinks alone. A resealable can matters if I might not finish one at once. |
| Packaging | Check the stated can format and local recycling arrangements if packaging affects your choice. Packaging does not change an airport’s liquid-container limit. | I may prefer a can, but I still need to check security rules and carrying space before choosing a multipack for travel. |
Common buying mistakes
-
Assuming a can is exempt from liquid rules
The container limit applies to water in a can as well as water in a bottle. GOV.UK says a 330ml container exceeds the limit at most UK airports even if it is partly empty.
Check your airport’s rule before packing cans in cabin baggage. Where the 100ml limit applies, take an empty refillable bottle or buy a drink after security instead.
-
Choosing a full case for one cabin bag
A multipack takes up space and adds weight. Nisbets lists Radnor’s 24 x 330ml case at 8.32kg.
Check the airline’s cabin-bag allowance and consider how many cans you will actually carry; a large case may be more practical for sharing or food provision.
-
Expecting flavoured sparkling water to taste like still water
DASH’s mixed pack is sparkling and includes fruit extracts and flavourings, so it is a different drink from plain still water.
Check the drink description before buying, especially if you want an unflavoured option with food.
-
Applying one airport’s rule to the whole trip
Heathrow says containers up to 2 litres can pass through its security, while GOV.UK says most UK airports retain a 100ml limit.
Check the current rules for your outbound, connecting and return airports separately.
Relevant brand formats
Cano Water
Still water in cans, with closure and capacity varying by product.
- An Amazon UK listing identifies a 24 x 330ml still-water pack with resealable lids; Joybuy lists a separate 24 x 330ml ring-pull product.
- Check the exact closure before ordering. A 330ml can remains subject to the airport’s liquid-container rules.
DASH Water
Fruit-flavoured sparkling water for shoppers who want a drink other than plain still water.
- Sainsbury’s lists a 12 x 330ml mixed pack and states that it has no sugar, sweeteners or calories.
- Its flavour and carbonation make it a different choice from still water; check security rules before carrying 330ml cans.
Northumbria Spring
Plain still spring water in a canned multipack.
- Tesco lists still spring water in 12 x 330ml cans.
- Check current availability and the rules for carrying 330ml containers at your airport.
Radnor
A 24 x 330ml still spring-water case to consider for shared serving or food provision.
- Nisbets lists a 24-can case.
- Nisbets gives the case weight as 8.32kg, which matters if you plan to carry it in cabin baggage.
Highland Spring
A bottled-water alternative when a can is not essential.
- Highland Spring describes bottles and boxes in its range; Tesco lists a 24 x 330ml bottled multipack.
- Do not mistake that bottled multipack for canned water. Bottles of this capacity also require an airport-security check.

Icelandic Glacial Natural Mineral Water 10 x 330ml
A 10-can natural mineral-water multipack for shared or airside use. Confirm whether it is still or sparkling and how the cans open if either detail matters to you; each 330ml container also needs an airport-security check.
Questions about airport travel
Can I take a 330ml can of water through UK airport security?
Not at an airport applying the 100ml container limit. GOV.UK says containers larger than 100ml cannot pass security at most UK airports even if partly full, so check the rule at each airport where you will go through security.
Can a 330ml water can pass through Heathrow security?
Heathrow says liquid containers of up to 2 litres can remain in cabin baggage through its security. That permission is specific to Heathrow: check any connecting or return airport separately, along with your airline’s baggage allowance.
Should I buy canned water before or after security?
If your departure airport applies the 100ml limit, buy 330ml cans after security rather than packing them to pass through it. An empty refillable bottle is another option for filling after security; check the rules again if you will pass through security on a connecting journey.
Is a canned-water case practical for one cabin bag?
Check its weight and dimensions against your airline’s allowance before buying it for one person. Nisbets lists Radnor’s 24 x 330ml case at 8.32kg, a substantial load if you also need to carry other belongings.
What is the difference between ring-pull and resealable cans?
A resealable can is the one to check if you expect to drink it over more than one sitting; a ring-pull can should not be assumed to close again. Cano Water has separately listed ring-pull and resealable multipacks, so confirm the closure on the exact product you choose.
