Most passangers travelling to Dublin from the US in Summer originate from the USA, they want to visit ‘ Ireland ‘
Their perception of Ireland is Dublin, Galway and Kerry in general.
They want a safe, friendly , English speaking country to begin their gentle transition to European Travel using 1 currency.
if you want their business you have to give it to them.
We tend to view transatlantic flights from what we want out of it and you won’t fill an aircraft consistently from Belfast
unless you make it attractive to Americans and Canadians,
it will take more than Titanic and Game of Thrones tours.
on the positive side, the more flights that land anywhere in Ireland, the more chance of visitors including Northern Ireland
in their travel plans and seeing how wonderful it is.
