This lump of rock we all live on (apart from those who live in Liverpool but choose to fly from BFS rather then MAN to the US) is the island of Ireland. The six counties of Armagh, Derry, Fermanagh, Down, Antrim and Tyrone form Northern Ireland: as in "Great Britain and Northern Ireland"! The rest of the island of Ireland is the Republic of Ireland.
8 out of 10 cuthere, you would have got 10 out of 10 if you had of spelt Derry correctly as in Londonderry, but well done anyway.
As for the arrival of Norwegian at Belfast - great news. A lot of people when going to the east coast, aren't necessary visiting New York or Boston but embark on a fly drive holiday. These smaller airports will be a great alternative and provide a niche above the other 'big' airports in the area. Less traffic competitive car hire and one road out of the airport rather than the complicated road networks within these large airports. Also these airports will be more convenient to use for inbound traffic who live on the right side of these American cities. I think the operation will be a success. All we need now is a 3-4 day year round operation to JFK, thrice weekly seasonal to Toronto, twice weekly April-October Orlando, LHR, Dubai daily, 8 more European cities EMA, Aberdeen and LBA. Once this is achieved BFS would be complete. Dublin can have the rest - happy days!
