Airport liquid rules in 2026 depend entirely on which security lane you happen to walk into. Some airports now allow 2-litre containers with no clear bag at all. Others still enforce the same 100ml limit they introduced two decades ago. Here is exactly where each rule applies, what counts as a liquid, which items are exempt, and what airlines owe you when the disruption goes beyond a confiscated bottle.
Twenty minutes to boarding. The officer pulls your bag off the belt, digs out a full-size sun cream, and drops it in the bin without breaking eye contact. Behind you, the queue stops moving. Somewhere ahead, your gate is closing.
It is a small humiliation with a big knock-on effect, and in 2026 it happens for a maddening reason: nobody can tell you what the airport liquid rules actually are any more. They changed. Then they changed back. Now they depend on which building you are standing in, and sometimes which terminal.
At Gyro we handle the wreckage of airport days that go wrong, from missed connections to cancellations to delays that stretch into the night. A confiscated bottle will not earn you compensation on its own. But the same trip that cost you a shampoo very often contained a disruption worth hundreds, and most passengers never claim it.
So here is the full picture. What the rules are right now, airport by airport, and what your rights look like when the day falls apart.
What are the airport liquid rules in 2026?
The default has not moved. Every container of liquid, aerosol, gel, cream or paste must hold 100ml or less, and all of them must fit inside a single clear, resealable bag of about one litre.
One detail catches people out constantly. Security measures the container, not the contents. A 200ml bottle with a splash left in the bottom still goes in the bin, because the printed capacity is what counts.
What has changed is that a growing minority of airports have been cleared to abandon that cap entirely. Where certified CT scanners are installed and signed off, you can carry containers of up to 2 litres, as many as you like, and leave them inside your bag.
The result is a genuine split system. Your outbound airport might wave through a litre of olive oil. Your return airport might not.
| Region | Standard limit | At certified CT airports | Clear bag needed |
| United Kingdom | 100ml per container | Up to 2 litres | No, at most major airports |
| European Union | 100ml per container | Up to 2 litres | Yes, unless the airport says otherwise |
| United States | 3.4 oz (100ml) per container | No change | Yes, one quart bag per passenger |
| Rest of world | 100ml per container | Varies by airport | Yes, in almost all cases |
One pattern shows up again and again in the claims we handle. Passengers who follow the rules perfectly still get caught by the gap between two airports on the same trip. Pack for the strictest one on your itinerary and the return leg never costs you anything.
Why does the 100ml liquid rule exist at all?
It started in August 2006, when authorities disrupted a plot to bring down transatlantic aircraft using liquid explosives hidden in hand luggage. The 100ml cap went in within days, as a stopgap.
The reasoning was blunt but sound. Traditional 2D X-ray machines cannot reliably distinguish a liquid explosive from a bottle of shower gel, so regulators capped the volume any single passenger could carry through the checkpoint. The European Commission has been explicit about that logic: the restriction exists because older screening kit cannot detect liquid explosives effectively.
That is also why the rule is finally cracking. CT scanners, known formally as Explosive Detection Systems for Cabin Baggage or C3 machines, use the same computed tomography principle as a hospital scanner. They build a 3D image and analyse what is inside a bottle without anyone opening the bag.
Where that equipment is installed and certified, the volume cap loses its purpose. Where it is not, the 2006 emergency measure is still running, two decades on.
The rollout has been anything but smooth. The Commission suspended the relaxations in Implementing Regulation (EU) 2024/2108, forcing every airport with the new scanners back to 100ml from 1 September 2024 over a technical certification problem, then re-approved recertified equipment in July 2025. If the headlines have given you whiplash, that is why.
We mention this history because it explains something practical. Airports mid-rollout are the ones where queues behave unpredictably, and unpredictable queues are how people miss flights.
Which UK airports have scrapped the 100ml rule?
The UK is furthest ahead, but the picture is still split. Heathrow lifted its 100ml limit at the end of January 2026 after a scanner upgrade reported at around £1 billion, the largest single deployment in the country. Gatwick, Edinburgh and Birmingham now run the same 2-litre allowance.
At those airports there is no clear plastic bag, no removing liquids, and no cap on how many containers you bring, provided each one stays under 2 litres.
Plenty of major airports have not made the switch. Scanners being installed is not the same as scanners being approved, and the Department for Transport signs off airport by airport.
| UK airport | Container limit | What to pack |
| Heathrow (all terminals) | 2 litres | Full-size toiletries fine, no bag needed |
| Gatwick | 2 litres | No metal or double-walled bottles |
| Edinburgh | 2 litres | Full-size toiletries fine, no bag needed |
| Birmingham | 2 litres | Full-size toiletries fine, no bag needed |
| Manchester | 100ml | Travel sizes only, can stay in your bag |
| Stansted | 100ml | Travel sizes only, can stay in your bag |
| Luton | 100ml | Travel sizes only, clear bag advised |
| Glasgow and Liverpool | 100ml | Travel sizes only, clear bag advised |
Two more airports worth a mention: Bristol and the Belfast airports publish 2-litre guidance on their own security pages, though coverage of their status has been inconsistent. Check the airport's own website before you pack anything oversized.
Note also that the UK Civil Aviation Authority's general baggage guidance still states the 100ml restriction as the standing regulation, because the relaxations are airport-level approvals rather than a rewrite of the national rule.
From the claims side, the airports mid-transition are the ones to give extra time. New scanners flag more bags for manual inspection while staff learn the equipment, and manual inspections are slow. If a long queue ends with you jogging towards a closed gate, ten minutes of research beforehand would have been cheaper.
Which European airports now allow 2 litres of liquids?
Ireland moved fastest. Dublin completed its rollout across both terminals in September 2025 and now allows containers up to 2 litres, with Shannon and Cork following the same path.
Italy is the other clear success story, though with terminal-level quirks that trip people up. Poland, Lithuania, Czechia, Malta and Denmark all have airports running the larger allowance too.
Germany is where the confusion bites hardest. Frankfurt, Munich and Berlin have CT scanners in some lanes and older machines in others, and you do not get to choose your lane.
| Airport | Status | Pack to |
| Dublin, Shannon, Cork | Full 2-litre allowance | 2 litres |
| Rome Fiumicino | Full 2-litre allowance | 2 litres |
| Milan Linate, Bergamo, Bologna | Full 2-litre allowance | 2 litres |
| Milan Malpensa | Terminal 1 only | 100ml if flying from T2 |
| Kraków, Vilnius, Malta, Billund | Full 2-litre allowance | 2 litres |
| Prague | Terminal 2 only | 100ml unless flying from T2 |
| Frankfurt, Munich, Berlin | Some lanes only | 100ml |
| Madrid, Barcelona, Paris CDG | Rollout in progress | 100ml |
This list moves month to month, so treat it as a snapshot rather than gospel and check your specific airport before you fly.
There is one trap even seasoned travellers walk into. Airports that otherwise allow 2 litres often revert to 100ml for flights heading to the United States, because American requirements apply to the departure screening. A litre of duty-free gin that sails through for Rome will not necessarily sail through for New York.
Do the airport liquid rules apply in the United States?
Yes, and nothing has been relaxed. The TSA 3-1-1 rule applies at every US checkpoint: containers of 3.4 ounces or less, all inside one quart-sized clear bag, one bag per passenger.
You may have read otherwise. In July 2025 the Homeland Security Secretary said the liquids policy was under review and hinted a change to permitted sizes might be announced. That comment produced a wave of headlines and no actual change.
What has changed is the experience, not the limit. CT scanners are now standard at big hubs like Atlanta, LAX, JFK, O'Hare and Dallas Fort Worth, so you often will not have to pull your liquids bag out of your carry-on. The 3.4 ounce cap still applies to what goes inside it.
Turning up at a US checkpoint packed for Dublin rules is one of the more expensive mistakes you can make, and it is a mistake people repeat every summer.
What actually counts as a liquid at airport security?
More than most people assume. The rule covers liquids, aerosols, gels, creams and pastes, and a good working test is whether you can pour it, pump it, squeeze it or spread it.
That definition sweeps in a surprising amount of luggage:
- Toothpaste, mascara, lip gloss and liquid foundation
- Aerosol deodorant, though solid stick deodorant is fine
- Peanut butter, honey, jam, hummus, yoghurt and soft cheese
- Contact lens solution, hand sanitiser and snow globes
Solid food is not restricted anywhere. Sandwiches, fruit, biscuits and crisps all pass without a second look, which is worth remembering if you are trying to avoid airside prices.
Water is the classic frustration. You cannot bring a full bottle through security anywhere on earth, but an empty one passes fine and refills for nothing on the other side.
One quirk applies even at the most relaxed airports. Vacuum flasks and metal double-walled bottles must be emptied regardless, because the insulation blocks the scanner from seeing inside. Travellers who have got used to the new freedom at Heathrow still lose flask contents at the belt.
Which items are exempt from the airport liquid rules?
Every regulator carves out the same core exemptions, and they apply whether your airport runs the 100ml rule or the 2-litre one. The EU's aviation security framework excepts special diets, baby products and medicines from the volume cap, and the TSA permits medically necessary liquids, breast milk, formula and baby water in larger quantities.
The condition is always the same: declare the items at the start of screening rather than letting them turn up in the scan.
| Item | Permitted amount | What to do at security |
| Prescription medicines, insulin, EpiPens | As much as your trip needs | Declare it, carry labels or a doctor's letter |
| Baby formula, breast milk, baby food | As much as the journey needs | Declare it, expect separate screening |
| Special dietary liquids | As much as the journey needs | Declare it, bring supporting documentation |
| Duty-free bought airside | No volume limit | Keep the sealed bag intact, receipt visible |
The duty-free exemption deserves a warning of its own. That tamper-evident bag is the whole basis of the exemption, and breaking the seal before your final destination voids it.
Connect through an airport that re-screens you under stricter rules and your litre of whisky can be confiscated at the transfer point, receipt or no receipt. Buy the big bottles on the last leg of the journey, never the first.
Can I claim compensation if airport security makes me miss my flight?
Here honesty matters more than optimism. A confiscated bottle earns you nothing, and a slow security queue on its own usually will not either.
Security screening is run by the airport or the state, not by your airline. That distinction is why EC 261/2004 and its UK equivalent do not treat a checkpoint queue as an airline failure, and why the airline will not pay you for missing your own flight.
But the story rarely ends at the checkpoint. Bad airport days tend to contain several problems stacked on top of each other, and some of them absolutely do trigger a payout.
If your flight itself departs late and you land three or more hours behind schedule, the airline may owe you between €250 and €600 in cash. Our guide on when a delayed flight actually qualifies for a payout sets out the thresholds in detail. If the airline cancels, the compensation rules and re-routing duties kick in on top of your refund rights.
There is also a scenario worth knowing about. If you clear security in time, reach the gate before it closes, and the airline refuses to board you anyway, that is denied boarding rather than a missed flight. Denied boarding carries its own compensation entitlement, and the burden sits with the carrier.
And while you wait for any of this to resolve, airlines are obliged to cover meals, refreshments and hotel rooms once a delay passes set thresholds. Those duties apply regardless of whether the chaos began at check-in, the gate or the scanner belt.
Something we notice constantly at Gyro: people remember the sun cream for years and forget the four-hour delay on the same trip that was worth €400. When passengers connect their inbox to our Autopilot scan, claimable disruptions from up to three years back surface all the time. Money that was always owed and simply never asked for.
Did you know?
The 100ml limit was introduced in 2006 as a temporary emergency measure after a foiled liquid explosives plot. Twenty years later it is still the global default, and the technology meant to replace it has already been switched off, re-approved and re-certified at least once.
How should you pack liquids so security never slows you down?
A handful of habits cover you at any airport, upgraded or not.
- Pack to 100ml unless you have confirmed that both your outbound and return airports allow more.
- Keep liquids near the top of your bag even where you are told they can stay inside, because manual checks are faster when things are reachable.
- Move anything oversized into checked luggage, where no security volume cap applies. Separate rules still govern aerosols and alcohol above 24% ABV.
- Empty metal and vacuum flasks before you reach the belt.
- Carry an empty water bottle and fill it airside.
- Photograph prescriptions and keep medical letters somewhere you can reach in seconds.
Give yourself margin as well. Airports with new scanners generally report faster queues, but the more sensitive machines also trigger more manual bag searches, particularly on bottles and food.
The technology improves the average experience while occasionally making an individual one much worse. Our wider playbook for staying ahead of airport disruption covers the rest of the pre-flight routine that keeps small problems from becoming missed flights.
The passengers who lose least at security are rarely the ones with the best knowledge of the rules. They are the ones who built in enough time to absorb a bad ten minutes.
What is the bottom line on airport liquid rules in 2026?
The airport liquid rules in 2026 are really two rules wearing the same name. The old 100ml standard remains the global default, enforced from Manchester to Miami. The 2-litre allowance is real but partial, live only where certified CT scanners have been signed off, and the list of qualifying airports changes every few weeks.
Until the rollout finishes, the smart approach is deliberately boring. Pack to 100ml, verify both ends of your trip before you fly, declare your exemptions, empty your flask, and buy duty-free on the final leg.
What should not get lost in the packing logistics is the larger point. The same trip where security binned your shampoo may well have included a delay, a cancellation or a missed connection worth several hundred euros, and that money is enforceable under regulation rather than granted as goodwill.
Airlines rely on passengers not knowing the difference. Roughly speaking, the vast majority of eligible claims across Europe go unclaimed every year, not because airlines successfully defend them but because nobody ever files. That is the gap we exist to close.
