New security regulations governing air travel in the EU will come into force next Monday.
These will impose new restrictions on travellers from Ireland but relax the current ban on carrying liquids on-board from British airports.
The new security rules from the European Commission will ensure the same restrictions on carry-on luggage apply at all EU airports. Currently, different restrictions apply depending on the airport passengers board at and their final destination.
Passengers queue at Dublin Airport
From Monday containers of 100mls or less of liquids, gels, pastes, lotions, cosmetics and contact lens solution may be carried on board.
The containers must be carried in a transparent, resealable plastic bag that must be presented separately at passenger screening. Only one such bag can be carried per passenger.
The volume of the transparent plastic bag may not be greater than one litre and it must measure less than 20cm by 20cm.
The only exceptions to the new rules are for baby foods and medicines needed during the flight.
Dublin Airport Authority (DAA) is recommending, that where possible, passengers pack all liquids into checked-in luggage.
The DAA will have additional customer service staff on duty from Monday to assist with the introduction of the new regulations.
It is also creating special areas before the passenger security screening point to prepare passengers for the new change and will be giving out the necessary plastic bags during the introductory period.
The UK banned most liquids and set smaller limits on carry-on bags in August following what police said was a foiled plot to blow up US-bound airliners leaving Britain using liquid explosives.
Some restrictions on hand luggage were eased in September.
Airport operator BAA has said the changes forced it to spend an extra £13 million sterling and British Airways estimated its lost revenues, the cost of hotel rooms for stranded passengers and of repatriating lost luggage after the restrictions were imposed in August at £40 million.
Budget carriers Ryanair and Easyjet also said they had lost money as a result of the disruption.
