Still seems odd that EI don't offer any form of connections. NQY-DUB-EDI etc
As both the UK and Ireland exist within their own "mini Schengen" area this would be perfectly possible, but to really make it so there would need to be flight time coordinated to ensure minimal transfer times in Dublin, and I guess that for just a couple of connecting pairs (eg. NQY to EDI / GLA) it would hardly be worth their while.
