TheJournal.ie is reporting a story that on the one hand doesn't surprise me, but on the other hand is kind of shocking.
RyanAir is to stop all its flights between Dublin and Cork, which effectively means that there will be no flights between Cork and Dublin. (Unless another airline steps in)
RyanAir claim that people are opting to drive (are they?) instead of fly.
RyanAir are a commercial entity, so it's their choice to run routes if they want to or not. If they weren't making enough money on a route they'd have to cut it eventually and focus on the ones that are profitable ..
But if you're based in Cork and need to fly to somewhere that isn't served by Cork airport, do you really want to drive to Dublin first?
Is the train an option? (From what I recall the last train from Dublin to Cork was relatively early .. )
