An "emergency plan" needs to be put in place urgently to deal with the projected increase in passenger numbers at Dublin Airport in the run-up to Easter, according to the chair of an Oireachtas committee.
Kieran O'Donnell, Chair of the Oireachtas Transport Committee, has described the ongoing delays at the airport as "very serious".
He was speaking after Committee members visited Dublin Airport and held talks with both management and staff.
There have been reports of lengthy queues to get through security at security in recent weeks.
The peak queue time at Terminal 2 was around 33 minutes between 6am and 8am on Saturday.
A spokesperson for the daa said passengers appear to be heeding its advice to arrive 3.5 hours before their departure time in order to avoid missing their flights.
The daa recently recruited 100 security screeners but Dublin Airport is looking to hire an additional 300 screeners amid what airport officials describe as a "challenging labour market".
Mr O'Donnell said it was "unacceptable" that there were "inordinate delays" for intending passengers, but added that his committee had been assured people will not miss their flights as a result of those delays.
The CEO of the daa, Dalton Philips, is to submit a plan to the Transport Committee by Wednesday regarding how the daa will deal with the expected rise in passenger numbers over the holiday period.
Last week Ryanair urged the Government to call in the Army in order to address lengthy security queues at Dublin Airport.
Mr O'Donnell confirmed that the daa was asked if Defence Forces personnel may be required to deal with the situation.
He said a short-term plan was needed to tackle the problem over the next ten days, and clarity was also required on how recruitment numbers could be expedited more quickly.
