From July 2009 Ryanair will close four routes from Dublin to Basel, Doncaster, Oporto and Teesside, and reduce frequencies on eight more routes from Dublin to Aberdeen, Biarritz, Billund, Bournemouth, Carcassonne, East Midlands, Malaga and Rome (Ciampino). These cuts will result in one additional based aircraft (five in total) being switched from high cost Dublin Airport to a low cost Ryanair European base in July.
