A union representing workers at Dublin Airport says it doesn't expect staffing issues to be resolved any time soon.
The DAA is understood to be speeding up recruitment following long queues for passengers that saw people waiting for several hours and some missing flights.
The airport authority has been accused of a "race to the bottom" over the terms and conditions on offer for new security staff.
Those applying are being told they must available for 40 hours of work a week but were only being guaranteed 20 hours, with a minimum weekly salary of €283.
Niall Philips from SIPTU says even if dozens of workers are hired, it takes six weeks to train them;
"From talking to our members who are on the frontline, the ASU officers and those who are involved in queue management, they can't see this being resolved anytime shortly."
