Dublin Airport has ushered in a new era of air travel convenience by implementing state-of-the-art C3 scanning technology, effective as of Friday. This groundbreaking upgrade eliminates the need for passengers to remove liquids, gels, or electronics from their hand luggage during security checks. Additionally, the previously restrictive 100ml limit on liquids and gels has been abolished, allowing travelers to carry containers of up to two liters without the requirement of clear plastic bags. This significant shift is attributed to a multi-million euro investment in advanced scanning systems, which utilize CT scanner-like technology to generate detailed 3D images of baggage, enhancing both security and efficiency. The airport has successfully completed its transition to full C3 operations ahead of its October 2025 target, marking a milestone in its commitment to improving the passenger experience. Gary McLean, Managing Director of Dublin Airport, hailed the development as a ‘positive and welcome change’ for both travelers and staff. While Dublin leads the way, other airports in the UK and Europe are still in the process of adopting similar technology, prompting officials to advise passengers to verify liquid rules at their departure airports. The move comes as part of a broader trend in the aviation industry to modernize security protocols, with Belfast International Airport also undergoing significant upgrades. The 100ml liquid rule, introduced in 2006 in response to heightened security concerns following the 9/11 attacks, is gradually being phased out as airports worldwide embrace advanced scanning solutions. However, challenges such as equipment weight and limited manufacturing capacity have slowed the rollout in some regions. Dublin Airport’s successful implementation positions it as a pioneer in European airport security innovation.
