I guess I am just getting annoyed that all the $300 deals end April 31'st! I found a few deals under $600, but one of them is sold out for the dates I need.. The other goes to Dublin or Shannon. (There is a $80 flight RT from Shannon to Belfast, or I can take the train from Dublin to Belfast). Anyone know the cost on the train from Dublin to Belfast?? It looks like a 2-3 hour trip.
