Many were concerned last week as images of long queues snacking around terminals emerged from Dublin Airport.

The images have caused anxiety for many who are due to undertake flights in the coming weeks.

Richard Cooper, the owner of Carefree Travel in Enniskillen, advised that part of the reason for mammoth queues were due to people arriving to the airport too early.

He said: “A lot of the reason [for the queues] is people are turning up too early for flights, obviously there is a security issue, but Dublin Airport are due to recruit extra people mid-June to early July according to them. Until then, at the moment, the best idea is to try and avoid the peak times of security.”

Detailing some of the peak times to The Impartial Reporter, Mr. Cooper said: “Terminal One for example, that is usually early morning from 5am to 8am and then in Terminal Two, it’s usually about 5am to 12 noon. The middle of the day is usually okay, but Terminal One for example has a second peak of security between 3pm and 7pm. Obviously weekends and especially weekends where there is a bank holiday can be especially busy.”

Advising what to do in the situation where you believe you will miss your flight, Mr. Cooper said: “If you do think you are going to miss a flight, the best thing is to try and get rebooked through your airline app alternatively if you are booked through a travel agent or tour operator see can they get you rebooked, the earlier the better.”

However, Mr. Cooper revealed that the previous week, some of his staff who were heading on a cruise, “they sent up a picture and there were no queues at all, it was plain sailing, it [the queues] is not a regular thing".

Kevin Cullinane, the group head of communications for DAA, the body that runs the airport, admitted they had got things “wrong” on Sunday, May 29.

“Significantly, we did not have sufficient staff manning sufficient posts throughout the airport to cope with demand early on and hence queues built up,” he told RTE radio.

“We clearly did not have enough lanes open in security from early on this morning, for the numbers who presented themselves at that hour of the morning. And that caused obviously a compounding effect throughout the morning.”

Mr Cullinane said there will be an additional 370 security staff in the airport from June
