WestJet has a low $207 one way fare LAX to Dublin, Ireland for several dates in October with a connection in Calgary. You can even add a checked bag for $30. Prices are much higher for the return flight, so this is only a real deal if you want to fly to Ireland one way and find another deal for the return.

Bono and Enya’s neighborhood Killiney, County Dublin is the article I wrote in Dec 2014 describing my walk when I took the Dalkey Island photo. It was a beautiful day.
