Given that Aer Arann's interline service from Cork to Dublin to avail of Aer Lingus's transatlantic services ex Dublin is helping them to sustain the route in competition with Ryanair, why don't Aer Arann extend this interline agreement to the regional airports? During this recession, Aer Arann need the extra business on the regional routes and so does Aer Lingus on its transatlantic services!
