More than 330,000 passengers are expected to travel through Dublin Airport over the Easter Bank Holiday weekend.
Around 2,000 flights will arrive and depart between Friday and Monday, a 9 per cent increase over the same period last year.
These include 120 charters for holiday-makers going to the sun, with Las Palmas, Lanzarote, Faro and mainland Spain being the most popular destinations.
Airport staff are advising all travellers to arrive at check-in at least 90 minutes before their flight departure time and to ensure to follow all security regulations regarding baggage and liquids.
"Once again passengers are reminded to remove all sharp objects from hand luggage," said a Dublin airport spokeswoman. "These objects should be packed into checked in luggage, in addition, all laptop computers must be removed from their outer casing for security screening.
Dublin Airport Authority also unveiled its newest check-in area, which will handle up to 4 million passengers a year and ease congestion considerably on the departures floor. Check-in Area 14, which has cost €15 million to build, will be used solely by Aer Lingus.
Subject to planning, the airport's second passenger terminal, T2, will begin construction this summer for delivery before the end of 2009. ends
