A senior Government Minister says there is no justification for the delays seen recently at Dublin airport.
The Government's demanded a plan from the DAA by this morning to ensure there is no repeat of the scenes witnessed on Sunday.
1,000 people missed their flights and thousands of passengers were forced to queue for hours outside and inside the terminal buildings.
Finance Minister Pascal Donohue says the airport has many indicators that allow it to know what kind of demands it's facing days, weeks and months in advance
He's called for issues with the airport to be fixed right away.
"Even if there are things that can be done differently or better to the structure of our aviation sector in Ireland, it's a sector that has served our country in recent years.
"But nothing can explain or justify what happened over the last number of days.
"It must, and the government expects, that it will improve."
Meanwhile, security staff say they faced abuse from some members of the public during the long delays.
