May be 25 mn walk ! It seems to me they connected T1 boarding area with another boarding area (new terminal ? Closed terminal 2 ?), it's endless, buildings, corridors, buildings, corridors, buildings.
So, you should ask if the flights to Dublin are close to the main area or not. If you don't get an answer, be there realy early.

Yes, if you walked very far to a new pier that was black glass and wood, that is the new T2B, soon to be part of T2, and triple in length.
Luckily for the OP, the Dublin flights depart from the Irish Tube to the North of T1, not near as long a walk as your CAI flight.
