If your flight departs Dublin Airport between 06.00 and 08.00 in the morning, you can now check-in at the airport between 16.00 and 20.00 the evening before.
This new service is available for Aer Lingus and Aer Lingus Regional flights. Regardless of the terminal your flight will depart from the following day, all bags need to be dropped in Terminal 2 when availing of this early check-in facility.
Each passenger needs to present themselves to check-in and drop off bags but if you are travelling with immediate family, one member of the family can check-in and drop bags for the group the evening before.
While this facility will save you time the next day, all passengers will still need to leave adequate time in the morning to get through security and to get to their gate. It is recommended that you come to the airport 90 minutes before your flight is due to depart.
A common sense idea from Aer Lingus.
