Over the next four days between Friday and Monday, the number of those travelling is set to be higher than during the busiest-ever October bank holiday weekend in 2023, which saw approximately 405,000 people.
Friday is set to be the busiest day of the weekend as 110,000 passengers are expected to arrive and depart from Dublin Airport.
This number includes 58,000 people who will depart Dublin for the weekend on Friday.
The DAA has advised passengers throughout this busy time to arrive at their terminal of departure two hours in advance of a short-haul flight and three hours before a long-haul flight.
Director of communications at DAA Sarah Ryan said this weekend will see many families departing and lots of tourists and rugby fans arriving in Ireland.
“This weekend marks the start of the school mid-term holiday, which will give many families an opportunity to embark on autumn getaways overseas,” she said.
“Many tens of thousands of tourists are set to fly into Ireland this weekend too, including Lions rugby fans ahead of their match against Leinster in the Aviva Stadium on Saturday evening.”
She also advised of the high demand for parking at the airport this weekend.
“Passengers without an existing booking should plan to travel to the airport by bus, taxi, or be dropped off,” she added.
To make the travel smooth during this busy period, Dublin Airport recommended that passengers prepare for security in advance and make their way directly to the security screening area once checked in.
Passengers travelling through both Terminal 1 and Terminal 2 should be prepared to take their liquids out of their carry-on bags and place them in the security tray.
All liquids being carried in hand luggage must be 100ml or under and need to be contained within a single transparent, re-sealable bag measuring not more than 20cm x 20cm – with exemptions for medicines and baby food.
However, passengers travelling through Terminal 2 can have as many one litre bags as they wish while Terminal 1 passengers are limited to only one bag.
This is due to the different scanning machines in operation in two terminals.
