Leo Varadkar has just been saying new routes on Morning Ireland.
I largely expect increased frequency on existing routes though.
Demand wise, you'd expect Cardiff and Newcastle to be favourites. Newcastle may suffer because it's not eligible for new route charging [Has Cardiff been gone long enough?]
With the increased oil and gas exploration going on off the south coast, Aberdeen could be a surprise. No massive demand, but potentially great yield for what demand there is. A long flight in an ATR though.
