They don't offer short-haul connections anywhere.
It's a bit of a pain that they don't offer them in Dublin, although I guess they'd only really be any use for passengers from other Irish destinations (which would imply an Aer Arann link-up), the north of England and Scotland. Anything else and you're flying in the wrong direction.
They used to have them and used to have one obscenely early flight from Cork to Dublin (around 5:15am) specifically to feed passengers onto the early morning departures to European destinations.
I guess someone must have looked at the revenues and costs involved and decided it wasn't worth it.
