Shannon Airport is changing its security screening process so passengers can keep liquids and electronic devices inside their cabin bags, while liquids in containers of up to two litres will be permitted through security. The updated process is designed to reduce the familiar unpacking routine at the checkpoint, although travellers should still check the rules at every airport on their itinerary.
The change follows the installation of newer screening technology at Shannon, according to a report by the Irish Mirror. For departing passengers, it removes two of the most persistent pre-flight chores: separating small liquid bottles into a clear bag and pulling laptops or tablets from hand luggage.
Under the revised Shannon Airport liquid rules, passengers can carry liquids in individual containers of up to two litres in their hand luggage. They will not need to take those items out for separate screening.
Laptops, tablets and similar larger electronic devices can also remain in bags as they pass through security. The airport’s newer scanners can produce more detailed images of a bag’s contents, allowing security staff to assess liquids and electronics without the old tray-by-tray routine.
The change should make packing less fussy for travellers carrying toiletries, drinks bought before security, baby supplies, cosmetics or larger bottles. It also makes the security lane simpler for families and anyone travelling with a laptop bag that seems to contain a small electronics shop.
The relaxed rules apply at Shannon Airport’s departure security point; they do not automatically apply at an airport used for the return journey, a connection or a later flight. Many airports still enforce the familiar rule limiting cabin liquids to containers of 100ml or less, often placed in a transparent resealable bag.
Passengers should therefore pack with the strictest airport on their route in mind. A two-litre bottle that clears security in Shannon may have to be checked in, surrendered or left behind when travelling home through an airport that still applies the 100ml limit.
Travellers can check the airport’s latest instructions through Shannon Airport’s security information before setting off. Screening procedures can change in response to equipment, regulatory decisions or operational requirements.
Airport security procedures are not identical across Ireland or Europe. The newer generation of CT-style scanners has allowed some airports to trial or introduce larger liquid limits, but deployment and regulatory approval vary by location.
That is why a passenger’s experience at Shannon should not be treated as a universal rule for every airport. Travellers using Dublin may also want to keep an eye on airport updates, particularly as passenger traffic remains high; Dublin Airport’s busiest month on record underlined the importance of allowing enough time before a flight.
The same applies to regional departures. Recent passenger growth at Cork Airport is a useful reminder that individual airports publish their own operational guidance, even when the destination and airline appear familiar.
No. The purpose of the new process is not to reduce security standards but to use equipment that can inspect cabin bags in greater detail. Security officers retain the authority to ask for a bag or item to be checked again, and prohibited items remain prohibited regardless of the size of a liquid container.
Passengers should not assume that every item will pass automatically. Security staff may still need clarification about an item’s contents, and normal rules on dangerous goods, sharp objects and airline-specific restrictions remain in force.
For regular Shannon passengers, the most useful adjustment is straightforward: there is no need to reorganise a bag around a 100ml toiletries collection before arriving at the security queue. Liquids and electronics can stay where they are, provided each liquid container is no larger than two litres.
It is still sensible to pack carefully. Keep valuable electronics protected, avoid packing items that could leak, and do not fill a cabin bag so tightly that an officer cannot inspect it if required. Faster screening is welcome, but no security lane enjoys an overstuffed bag with twelve charging cables tangled around a shampoo bottle.
Yes, Shannon Airport’s updated process permits liquids in individual containers of up to two litres in cabin baggage. The airport may still inspect any item further if required.
Passengers using the new Shannon Airport screening process do not need to remove liquids from their cabin bags for separate screening. Check the latest airport guidance before travel, as procedures can change.
No. Laptops, tablets and other electronic devices can remain in hand luggage under the revised screening arrangements at Shannon Airport.
Not necessarily. The return airport may still require liquids to be in containers of 100ml or less, so check its rules before packing for the journey home.
