Queues for security have fallen to ten minutes at both terminals today.
50 thousand passengers will depart from the airport each day of the bank holiday weekend.
Dublin Airport Authority hired 200 staff to ensure a repeat of last week's chaos didn't occur.
Marquees which were erected to contain overflowing queues have not been needed since around 5 o'clock this morning.
DAA Media Relations Manager Graeme McQueen, says they'll continue to improve services as the busy summer months arrive:
"Passengers can have confidence today that they can get here 2.5 hours before a short-hall flight and 3.5 hours long-haul flight. Give yourself that extra hour for the baggage drop. You'll get off to where you want to be in plenty of time".

"The hiring of staff goes on. It's been a rapid process over the last few months. We will hire another 80 before the end of this month. That will take us to our target of having 700 security officers in place".
