I wouldnt be surprised if Knock soon had a Ryanair based aircraft after the news from Shannon this evening. I would say Ryanair are getting free charges from Knock anyway considering the steady stream of new routes over the last few years.
Its not the ideal scenario to have ryanair as the only operator at an airport however Iwak has limited options when it comes to attracting low cost airlines. Easyjet aint coming to Ireland anytime soon and you need big brands to sell routes.
If Knock could hold onto Bmi Baby and Aer Lingus and Have Ryanair as their based airline with new routes they would be doing well.Although bmi babys future will be revelaed next weds from their new owner!
