Dublin Airport has suspended the sale of fast track security passes in an effort to speed up the current security chaos.
The Dublin Airport Authority has confirmed that it is suspending the sale of new passes "for the time being".
The fast track system allows passengers to purchase tickets at self service kiosks, allowing them to bypass the security queues.

However, due to the current delays, that service has now been suspended.
In a statement published on the daa Twitter account, they said: "Dublin Airport has paused the sale of new Fast Track passes for the time being.
"This move is one of a number of measures being taken to improve the security screening process for all passengers."
"Additionally, Dublin Airport can confirm that, given the difficulties faced by passengers last weekend, all Fast Track bookings from March 25-27 are being refunded."
Delays of up to three hours have been experienced by passengers at security over the past few days.
One passenger told Dublin Live: "It was so awful. Got in queue at 7.10am, got through security at 9.00am. So many people missing flights. 8 lanes unopened in security."
Others took to Twitter to slam the "outrageous" delays.
One wrote: "Arrived at the airport at 4am this morning for a flight at 6:25am missed the flight because we couldn’t even get into the security queue until 6am had to book another flight, just getting home now”
Another said: “Absolutely chaotic scenes - It took us nearly 3 hours to get through security this morning. Felt so so sorry for all the parents with young children."
Ryanair also issued a statement advising passengers to arrive for their flight at least three hours before the scheduled travel time..
"We apologise to our customers for these unfortunate delays entirely out of our control," they added.
