Aer Arann seem to be upping the Galway service next summer to allow for day returns on most working days.
The schedule is showing as
Mon 2x daily
Tues 1x daily
Wed 2x daily
Thurs 2x daily
Fri 2x daily
Sat No Service
Sun 1x daily
All services seem to be operated by a Galway-based aircraft, so hopefully there won't be any nasty cuts on other routes to make capacity.
I still regard this route as an indictment of the other public transport options in Ireland, although with the timings, it could be one of the first real opportunities to see passengers using Cork as a place to connect on to other airports not available to them locally.
