The operator of Dublin Airport has said the wait time to get through security checks during peak hours at Terminal 1 this morning was 47 minutes.
The peak queue time at Terminal 2 was around 33 minutes between 6am and 8am.
A spokesperson for the daa said passengers appear to be heeding its advice and arriving well before the departure time to avoid missing their flights.
The daa said there are no more screeners at security this weekend compared to last weekend, but the system is running much more efficiently because staff have been deployed from other areas of the business to help keep the operation running smoothly.
Staff from back-office roles at the daa are supporting screening staff by helping prepare passengers in advance - giving them information ahead of screening and combing queues to identify passengers who need assistance.
Group head of communications for the daa Kevin Cullinane said that so far the "productivity rate" is much improved on last weekend.
"This morning no passengers have missed their flights and that is the key litmus test for us this weekend, he added.
The daa has 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".
The airport expects queueing times to peak and trough throughout the day.
The daa said one key improvement is keeping security open through the night which is preventing the build-up of a log jam of passengers waiting to get through first thing in the morning.
Dublin Airport is still advising passengers to arrive 3.5 hours before their flight is scheduled to depart.
A daily crisis meeting with Minister of State at the Department of Transport Hildegarde Naughton is due to take place later this afternoon.
Separately, Cork Airport said it is confident that it is adequately resourced to deal with increased passenger numbers through the airport as the summer schedule kicks in.
Airport spokesman Barry Holland said the average wait for the vast majority of customers is currently between 10 and 15 minutes.
"We are not experiencing the same level of backlog that is being experienced in Dublin".
Mr Holland also confirmed that a number of trained airport security staff have been re-deployed on a temporary basis from Cork to Dublin Airport to bolster queue management and security staff numbers there but stressed Cork Airport remains well resourced.
The airport's 2022 Summer Schedule commenced last Sunday with 41 routes, operated by eight airlines.
