Having a look at the airports facebook page it looks like their targeting Prague (Known since June) but also two routes which where all scheduled at Cork at one time which i didnt no they where looking to re-target Krakow and Madrid. Looking at Krakow i think the likely carrier here would be Aer Lingus, Ryanair or Wizz Air to a lessor extent and looking at Madrid either Aer Lingus or Ryanair. Also Targeted are London City, Düsseldorf, Berlin, Leeds/Bradford, Southampton, Brussels, Frankfurt and a big suprise Togher
could be possibly the shortest air route after the one in Scotland
