With the termination of the PSO routes to most of the regional airports, Aer Arann/Aer Lingus Regional should reinstate the Dublin-Cork flights allowing connections not just to transatlantic flights but to other destinations not available from Cork and to destinations already available from Cork to complement the existing Cork schedule. These interline services would facilitate the business traveler which Ryanair Cork-Dublin services doesn't really cater for. Otherwise interline businesss travelers will continue to travel to/from Cork via London and Amsterdam.
