There is very little direct competition and hence chance of a monopoly occuring should IAG offer and succeed in gaining a controlling interest in Norwegian. Norwegian does bucket and spade routes which are ten a penny with airlines competing for business. Their longhaul operations whilst including some main hubs also have a fair amount of secondary airports. Anyway this would have all been ticked off the boxes by Willys advisors well ahead of the share purchase. Thats what you pay the big bucks for.
