Ryanair
Aerlingus, BMI Baby, Aer Arann, Wizz and Central Wings are all operating routes from Cork that are in broad competition with Ryanair flights from Shannon. It's also obvious from the amount of cars registered inn Limerick and Clare in the carparks at Cork Airport that its not all one way traffic.
If Ryanairs Shannon operation is such a brilliant move why has MOL drawn attention to disappointing yields there on several occasions over the last year and a half?
