Nearly a quarter of a million passengers will depart from Dublin Airport over the next five days.
The DAA yesterday unveiled its plan for the June Bank Holiday weekend, with more screening staff and extra security lanes.
Passengers who arrive too early could be placed in holding areas if the terminals are too busy.
DAA spokesman Graeme McQueen is confident there'll be no repeat of last weekend's chaos:
" I think we've learned the lessons from last weekend. We've looked at what went wrong, and we're gonna make sure that doesn't happen again. What we've been doing this week is making sure we have staff levels where they need to be for the weekend ahead. It is going to be a busy weekend, but we're confident that the operation will work well".
It's been reported that a new plan will be in place for the bank holiday that could see holding areas outside the terminals for people who show up too early.
However, the head of the DAA Dalton Phillips, has said he doesn't believe these areas will be needed this weekend if passengers follow advice on arrival at Dublin Airport.
Passengers are recommended to arrive two and a half hours before a short-haul flight and three and a half before a long-haul trip.
An extra hour is being advised for those who have to check in a bag.
