The operator for Dublin Airport has again warned that queues at security checks can be expected at peak times over the coming days and weeks.
The daa said people travelling through Dublin Airport should "be prepared for things to take longer".
It has advised passengers to arrive in plenty of time for their flight, at least two hours prior to a short-haul service and at least three hours in advance of a long-haul flight.
Operations at Terminal 1 and Terminal 2 were running smoothly this afternoon, with queues of between just 10 and 15 minutes to get through security checks.
It was in contrast to the scenes at times in recent days, including on Sunday evening, when hundreds of people were standing in lengthy queues for security.
Some passengers reported being delayed for several hours and having missed flights, as a result.
A number of airlines have also issued advice to intending passengers, as the daa continues efforts to resolve the problem.
Aer Lingus today said "rush hours at Dublin Airport security are busier than ever."
In a tweet, it said unfortunately this is due to daa staff shortages and it's out of our control."
Ryanair advised people that they should arrive at Dublin Airport at least three and a half hours before their scheduled departure time.
It said "check-in desks, kiosks and baggage drop will be open 3.5 hours before departure."
The airline has apologised to customers for what it described as "these unfortunate security delays, which are entirely out of our control."
Earlier today, the Chief Executive Officer of the daa has said they are "recruiting aggressively", following recent reports of lengthy queues to get through security at Dublin Airport.
Dalton Philips said there are currently 600 officers in the security division, but staff levels need to reach 900.
Speaking to RTÉ's News at One, he said there is "very significant pent-up demand" and it is much higher than experts anticipated.
He said there are 15,000 extra passengers per day passing through the airport, which is 30% higher than the forecasted number.
"We are grappling to deal with this very high demand at a time when the labour market is incredibly tight," he said.
Mr Philips said one issue is the intensive background security checks that must be carried out on a person after they are recruited and before they can start work.
"You have to have enhanced background checks for all employees in an airport," he explained.
"It's essentially like garda vetting plus plus, so it's very rigorous."
He said that this combined with the challenges presented by Covid-19 is a "perfect storm" for staffing levels.
Responding to criticism of the conditions afforded to workers, Mr Philips insisted that the starting rate of pay for security workers is 35% higher than the national minimum wage.
He said contracts are a minimum of 20 hours, but up to 40 hours per week. All staff are currently being asked "to do as many hours as they possibly can for obvious reasons".
"In the industry, the reason why it's not guaranteed 40 is because as you can imagine, there's a lot of variability, peaks and troughs, between not only the day in the week, but obviously the season between winter and summer," he said.
Meanwhile, the Taoiseach has criticised the terms of employment being offered by the daa for security staff and said he will raise the issue with the company.
Speaking in the Dáil, Micheál Martin said it is clear that "more worker friendly approaches" were needed.
Mr Martin noted that the daa has "recruited 100 new security staff" recently to help with delays at the airport, and he insisted that the daa is "working extremely hard" to deal with those delays.
The conditions of employment were raised by two deputies during Questions on Promised Legislation.
Social Democrats TD Cian O'Callaghan said the daa is guaranteeing 20 hours work a week and weekly pay of €283, but demanding that staff be available to work 24/7, and up to 40 hours a week.
Deputy O'Callaghan accused the daa of engaging in "a race to the bottom".
Richard Boyd Barrett of Solidarity-PBP called the terms of employment "an absolute insult" and said private security workers "are shockingly badly paid".
