The operator of Dublin Airport will publish its plan to tackle long delays for passengers today.
The DAA will appear before the Oireachtas Transport Committee, and outline how queues, similar to last weekend, will be avoided.
More than 1,400 people missed flights after staffing issues at security resulted in long lines forming outside terminals.
Yesterday the operator admitted to ministers it can't guarantee what happened at the weekend won't be repeated again.
Independent Senator and committee member, Gerard Craughwell, says the situation is a mess.
"Telling us at this stage that they cannot guarantee that next weekend is not going to be a disaster - that is just unbelievable at this stage.
"We're coming in to the biggest bank holiday of the year, and we cannot be sure that we will get people out of the airport on time.
"Already we have 1000 people I understand who will be making a claim against the DA for loss of flights, loss of hotel accommodation, lots of theatre tickets, and God knows what else."
