The BHX route is not likely to be taken up as SNN-BHX has recommenced.
IAG have to give up 5 slots for the Belfast and Dublin routes, not for the Knock routes. Any operators bidding won't operate a service to NOC, but theoretically they could take away the slot from NOC, although that's unlikely as its a top preformer.
How's the Izmir charter doing? Any news on the bookings?
