I think a Brussles route out of EICK would be an excellent expansion for Aer Lingus if the costs were low,
SN Brussles were in last year and I have a cousin over there in Brussles and he found himself driving out to Cheroli to go to EINN and then to get a bus home to Cork, becasue Ryanair have very low prices and SN Brussles were through the roof!!! So if Aer Lingus made that route to main airport in Brussles to Cork he'd have an easy time getting home.
The Glasgow expansion would be good the loads were meant to be excellent on the Loganair route, and I don't know why they gave it up? It seems fairly stupid to me? So if Aer Lingus or Ryanair even steped in and provided a route to Prestwick or the main airport in Glasgow it would be excellent.
