The 2-liter allowance depends on where your liquids are screened
Airports across Europe now accept larger liquid containers at the checkpoint. The changes began in July 2025 and more airports have joined since. Two liters is 67.6 US fluid ounces. The allowance comes from computed tomography scanners, which build a three-dimensional image of a bag and clear liquids without the 100 ml cap.
The rule that governs your bag is the one in force at the airport where your liquids go through screening. That airport appears on your outbound ticket, and it appears again at every connection where you clear security a second time.
Where containers up to 2 liters clear security
Czech Republic: Vaclav Havel Airport Prague allows one container larger than 100 ml and up to 2 liters per person, alongside liquids in containers up to 100 ml inside a 1-liter transparent bag. The allowance covers departures from Terminal 2, and Prague dates it from 1 October 2025.
Denmark: Billund Airport accepts liquids, creams and fluids in containers of up to 2 liters, and the containers stay in the cabin bag.
Germany: Frankfurt Airport runs CT scanners at most Terminal 1 checkpoints and at all Terminal 3 checkpoints, where containers up to 2 liters are accepted and a transparent resealable bag is not required. Gates C1, C2, C4 and C6, certain special Terminal 1 checkpoints and the transfer checkpoints keep individual containers of 100 ml inside a bag of 1 liter total capacity. Munich Airport applied the 2-liter rule at all of its checkpoints from 18 September 2026.
Italy: Bologna Airport accepts up to 2 liters per container for all passengers and all destinations, in force since 28 July 2025. Rome Fiumicino has accepted 2 liters per container since 26 July 2025. Turin allows the larger containers at its Fast Track priority lane, and the standard security lines keep the 100 ml limit.
Lithuania: Vilnius and Kaunas airports accept containers up to 2 liters and let passengers keep liquids and electronic devices in the cabin bag.
Poland: Krakow's passenger page states liquids in any quantity in containers of up to 2 liters each, with no need to remove them from the bag. Poznan-Lawica dates its change to 9 September.
United Kingdom and Ireland: Heathrow accepts containers up to 2 liters at Terminals 2, 3, 4 and 5, and liquids stay inside the cabin bag. London Southend allows up to two liters, requires no clear plastic bag and bars aerosols larger than 500 ml from hand and hold baggage. Shannon Airport moved to containers up to two liters on 7 September 2026, replacing its 100 ml restriction. Dublin Airport accepts containers up to 2 liters and no longer requires clear plastic bags for liquids and gels.
The 8 October round-up this piece works from adds a further set on the same allowance: Gatwick, Bristol, Birmingham, Bournemouth and Edinburgh in the United Kingdom and Ireland, Milan Linate and Malpensa Terminal 1 in Italy, Warsaw Chopin at 8 of its 15 screening lines, and Gdansk at selected stations. Read a specific airport's own page before packing for it.
Conditions that travel with the bigger allowance
Metal and double-walled bottles must be empty when they reach the checkpoint at Heathrow, and passengers can refill them after screening. Southend excludes aerosols above 500 ml from both hand and hold baggage. Prague counts one container per person above 100 ml. Frankfurt asks passengers to prepare for the traditional 100 ml limit, because a traveller cannot tell in advance which checkpoint type they will meet.
The United States keeps the 3-1-1 rule
TSA limits carry-on liquids to containers of 3.4 ounces, which is 100 ml, inside one quart-sized clear bag, and that standard held through 2026 at United States airports. CT scanners are installed at many large US hubs, and officers can clear larger liquids on the equipment. The container limit itself has not changed.
Routes where the smaller limit still applies
Heathrow states that liquids in containers over 100 ml cannot be taken on flights to Australia. Rome Fiumicino screens flights bound for the USA and Israel on traditional X-ray machines, where containers are limited to 100 ml inside a resealable transparent bag of up to 1 liter, one bag per passenger. Across the UK, containers up to 2 liters are accepted at all airports when they hold baby food, baby milk or liquids for essential medical purposes or special dietary requirements, and most UK airports otherwise keep the 100 ml limit. Most European airports also keep 100 ml containers inside a 1-liter bag.
Lublin stays on 100 ml
The 8 October round-up lists Lublin Airport as allowing up to 2 liters. Lublin's own carry-on page keeps one liter per passenger, split across a maximum of ten transparent 100 ml containers. A Polish airport list updated on 17 September 2026 marks Lublin as still under the limit. Fly4free reported on 28 August 2025 that Lublin's scanners had not passed the certification that the Poznan and Krakow equipment held. The airport's own rule did not follow the July 2025 headlines.
Check the return leg and every connection
A bottle that cleared security in Dublin carries no exemption at an airport that limits containers to 100 ml. When the container is larger than the local allowance, the options are checked baggage, disposal or confiscation. Re-screened connections follow the rule of the connecting airport. Pack for the strictest airport on the itinerary, and check the rule again before the return flight.
