Hi Roker, I would go along with Gianni. The 10.30 ,11.30 , 12.30, 13.30 and 14.30 trains from Cork to Dublin are costing 20 euro one way. It is the hassle free way to go from Cork to Dublin, No waiting for baggage in Dublin and no extra charges.The time frame is about the same anyway, One hour at cork airport, 45 minutes on the flight before getting off and another 30 minutes waiting for luggage,and another 30 minutes getting in to town = 2.45 hours , Same as the train. Personally I would write off the 22 euro.
