The only route listed that could be a bloodbath is BCN. You might say how many airlines can be on the MAN-BCN, but that hasn't stopped airlines in the past, easyJet would have an advantage over the like of Vueling as they have a strong presence in both the UK and Spain and are recognisable in both.
Also I was questioning the launch of the Tivat route not because of its beauty, but I was questioning if there is enough demand and the aircraft could be used in a stronger market.
