THE DAA has released a five point plan which will aim to address the recent delays experienced by passengers at security screening during peak times at Dublin Airport.
People have been missing flights and experiencing long wait times in recent weeks, with videos on social media showing the chaos at the terminals.
The new measures have been introduced over the past ten days, with daa saying none of 300,000 passengers that have departed out of the airport since 27 March have missed flights.
"However, with Dublin Airport set to get busier over the coming weeks, passengers are being reminded to arrive at the airport a minimum of three and a half hours prior to their departure time," a statement read.
"Dublin Airport, like other major airports in the EU and the UK, is currently working to build back operations following the collapse of international travel over the past two years due to Covid-19."
The daa said it is firstly re-doubling its efforts to recruit additional staff, and has invited 250 candidates for an interview this week.
It is also exploring other options to increase staff, "including identifying former security screeners still employed by daa but now in different roles in the company and reaching out to those currently on career breaks."
The daa is also increasing training capacity, and has contracted third party security trainers to expand the training capacity for new recruits.
It says a Task Force which was first deployed on 31 March will continue to play a role in alleviating pressure on the operation and queue times in the coming weeks.
A targeted communications campaign advising passengers to allow three and a half hours before departure time will continue to be issued, with a radio national campaign amplifying the message.
Fast Track options can no longer be purchased, although bookings already made continue to be honoured.
An extensive review of the layouts of existing security lanes has been undertaken and additional equipment has been provided to improve passenger throughput. This is continuing to be adjusted as the operation builds.
The plans were presented to Minister of State at the Department of Transport Hildegarde Naughton at a daily briefing on the measures being taken to address the ongoing challenged.
daa has also written to members of the Oireachtas Transport Committee to outline these plans.
The letter follows a visit to Dublin Airport by the Committee on Monday where they met with daa management.
Ryanair had previously called on the Department of Transport to hold an emergency meeting of the National Air Transport Facilitation Committee about the lengthy queues at the airport.
"The Department of Transport must take responsibility for helping the daa to solve this short-term staffing problem," a spokesperson said.
