Whatever aircraft UKIA may or may not have it's unlikely to be able to turn a profit unless it's utilised properly, which doesn't appear to be the case, it seems doubtful that 2 flights a week could generate enough income to make the operation viable, certainly with their load factors.
I imagine that UKIA had plans for more routes which would possibly have helped, maybe they should have been a little more sorted when they first started with their route network and ticketing arrangements, which appeared to be very poor initially.
