Not a very busy airport so you can expect a relaxed time. There is certainly plenty of space and the new check in hall is very impressive. Security are quick but thorough. The random checks at the boarding gates are a feature of all Irish airports but they are friendly at doing there job: just don't give them any crap and you'll be fine. The Duty free is well stocked for an airport of this size and the staff are very friendly. One exception to this is the staff at Passport control (members of the Irish police) who could seriously do with some people skills.
