You're at security with twenty minutes until boarding. The officer pulls your bag aside, fishes out a full-size sunscreen, and drops it in the bin. Nothing ruins the start of a trip quite like watching €15 of toiletries disappear - except maybe the queue that forms while it happens. And here's the frustrating part: in 2026, the airport liquid limit depends entirely on which airport you're standing in. Some now wave through 2-liter bottles. Others still enforce the same 100ml rule they introduced twenty years ago.
At Gyro, we deal with the aftermath of airport chaos every day - delayed flights, missed connections, cancelled departures. Liquids won't earn you compensation on their own, but the confusion around them causes real disruption. So here's the full picture: what the rules actually are right now, where they've changed, and what your rights are when an airport mess turns into a missed or delayed flight.
What is the airport liquid limit in 2026?
The default rule hasn't moved: each container of liquid, aerosol, gel, cream, or paste must hold 100ml (3.4 ounces) or less, and all of them must fit in a single clear, resealable bag. That applies to the container size, not the contents - a half-empty 200ml bottle still gets binned, because security measures the vessel, not what's left inside it.
The twist is that 2026 is a transition year. Following recertification of CT scanning equipment by the European Civil Aviation Conference (ECAC) in July 2025, airports with approved scanners can allow containers of up to 2 liters. The result is a patchwork. Your departure airport might let you keep a full-size shampoo in your bag. Your return airport might confiscate it. Until the rollout finishes, the only safe assumption is 100ml unless you've checked both airports.
Here's how the rules break down by region right now:
One pattern we see constantly at Gyro: travellers who follow the rules perfectly still get caught by the gap between airports. Pack for the strictest airport on your itinerary, not the most generous one, and your return leg won't cost you a bag full of toiletries.
Why does the 100ml rule exist?
It started in August 2006, when authorities foiled a plot to bring down transatlantic jets using liquid explosives smuggled in hand luggage. The 100ml limit went in as a temporary measure - and stayed for twenty years. The logic was simple: traditional X-ray machines cannot effectively distinguish a liquid explosive from a bottle of water, so the only safe option was capping the volume any one passenger could carry.
That's also why the rule is finally cracking. New CT scanners, known as C3 or Explosive Detection Systems for Cabin Baggage, use computed tomography to scan bags with far greater accuracy - the same technology hospitals use. They can analyse a liquid inside your bag without anyone unpacking it. Where that kit is installed and certified, the volume cap loses its purpose.
The road has been bumpy, though. The European Commission actually reversed early relaxations in September 2024, forcing airports with the new scanners back to 100ml over a technical issue, before re-approving recertified equipment in July 2025. If you've felt whiplash reading the headlines, that's why.
Which airports let you carry more than 100ml?
The 2-liter club is growing, but membership changes month to month. As of early 2026:
- UK: passengers at Heathrow, Edinburgh and Birmingham can take containers of up to 2 liters through security, and at all major UK airports liquids no longer need to come out of your bag. Luton and Manchester, however, still enforce the 100ml cap. London City and Teesside were among the first movers back in 2024.
- EU: Rome Fiumicino and Milan's Linate and Malpensa airports began accepting containers up to 2 liters from 26 July 2025, and Dublin completed its rollout across both terminals by September 2025. Big German hubs like Frankfurt and Munich have CT scanners in only some lanes, so the 100ml rule still governs packing there.
- US: nothing has changed. CT scanners at major hubs mean you often don't need to remove your liquids bag, but the 3-1-1 limits themselves still apply.
Two traps to watch. First, an upgraded departure airport doesn't help you on the way home if your return airport hasn't caught up. Second, some airports apply the 100ml rule to US-bound flights even where the 2-liter allowance otherwise exists, because of stricter American requirements. Check both airports' websites within a week of flying - this is one of the few travel rules that genuinely changes faster than guides can keep up.
From our side of the claims desk, the airports mid-rollout are the ones to budget extra time for. New scanners flag more bags for manual checks while staff bed in, queues stretch, and passengers cut it fine. If a long queue ends with you sprinting to a closed gate, knowing your departure airport's current setup in advance is cheaper than learning it at the belt.
What counts as a liquid at airport security?
More than you'd think. The rule covers liquids, aerosols, gels, creams, and pastes - a useful test is: if you can pour it, pump it, squeeze it, or spread it, security treats it as a liquid. That sweeps in some surprising items:
- Toothpaste, deodorant sticks vs sprays (sprays count, solid sticks don't)
- Peanut butter, jam, honey, and soft foods like yoghurt and soft cheese
- Mascara, lip gloss, liquid foundation
- Snow globes, contact lens solution, hand sanitiser
Water is the classic one. You can't bring a full bottle through security anywhere, but you can bring an empty one and fill it airside. Cheap, legal, and it spares you airport water prices.
What items are exempt from the airport liquid limit?
Every regulator carves out the same core exemptions. The EU's aviation security rules explicitly except special diets, baby products, and medicines from the 100ml restriction, and the TSA permits medically necessary liquids, breast milk, formula, and baby water in larger quantities, provided you declare them at the start of screening.
The duty-free exemption deserves a warning. Liquids bought airside come in a sealed tamper-evident bag, and that seal is what protects them. Break it before your final destination - or connect through an airport that re-screens you under stricter rules - and that liter of whisky can be confiscated at the transfer point. Buy big bottles on the last leg of your journey, not the first.
Can I get compensation if security delays make me miss my flight?
Here's where liquid rules meet passenger rights, and the answer needs honesty: confiscated toiletries don't qualify for compensation, and a security queue alone usually won't either. Airport security is run by the airport or the state, not your airline, so EC 261 and UK261 don't treat a slow checkpoint as the airline's fault.
But the disruption rarely ends there. If your flight itself departs late and you land 3 or more hours behind schedule, the airline may owe you €250 to €600 regardless of what happened to you at security - our guide on how delayed flight compensation works walks through exactly when you qualify. And while you wait, airlines must cover meals, refreshments, and even hotel rooms once a delay passes set thresholds. Those rights apply whether the chaos started at check-in, the gate, or the scanner belt.
Something we notice again and again at Gyro: passengers who lose a sun cream at security remember it for years, but forget the 4-hour delay on the same trip that was worth €400. When people connect their inbox to our Autopilot scan, disrupted flights from up to 3 years back surface all the time - money that was always claimable and simply never claimed.
How should I pack liquids to get through security faster?
A few habits cover you at any airport, upgraded or not:
- Pack to the 100ml standard unless you've confirmed both your outbound and return airports allow more.
- Keep your liquids bag at the top of your cabin bag, even where you're told it can stay inside - manual checks are quicker when it's reachable.
- Move anything over the limit into checked luggage, where no liquid volume cap applies (aerosols and alcohol have separate quantity rules).
- Carry an empty water bottle and fill it after screening.
- Photograph prescriptions and keep medical letters handy if you're carrying exempt liquids.
And give yourself margin. Airports with new scanners report faster queues overall, but the sensitive machines also trigger more manual bag searches, especially on items like bottles and food. The technology is improving the average experience while occasionally worsening the individual one.
The bottom line on airport liquid limits
The airport liquid limit in 2026 is really two rules wearing one name. The old 100ml standard remains the worldwide default, enforced everywhere from Manchester to Miami. The new 2-liter allowance is real but partial, live only at airports with certified CT scanners - and the list shifts constantly. Until the rollout completes, the smart play is boring: pack to 100ml, check both airports before you fly, declare your exemptions, and buy duty-free on your final leg.
What shouldn't get lost in the packing logistics is the bigger principle. The same trip where security binned your shampoo may have included a delay, cancellation, or missed connection worth hundreds of euros - enforceable money under rules airlines are legally bound by, not goodwill. Airlines bank on you not knowing that. We exist to flip those odds. Check your recent flights with Gyro, or connect your inbox and let Autopilot find every claimable disruption from the past 3 years while you get on with planning the next trip.
