Save time and have a smoother journey by preparing correctly and ensuring that all items in your hand luggage meet security requirements. 

Departing passengers

Help us reduce the queues at security control by ensuring that you do not pack prohibited items in your carry-on luggage. Make sure you leave plenty of time after check-in for the security screening process. Passengers should plan to arrive in the terminal building at least 2 hours before their flight departure time irrespective of whether they are checking in online or at the airport. Dublin Airport would like to thank all passengers for their cooperation with security procedures. Please watch our security preparation video below.
