Whats all this stuff about PSO, LDY, etc to do with Ryanair? If you want comment on those issues, a DUB-Belfast route was tried a few times and failed. Even less chance now with the new motorway. A new road is out to tender from the border to Londonderry to link with the much improved link from Dublin to Monaghan. When completed, admittedly a few years away, it will blow a Dub-Ldy air route completely out of the water.
