I would like to ask about what happens if one flies into Northern Ireland from one of the 44 countries that UK citizens can fly to and from. I am not suggesting that one can fly to 44 countries from Belfast as I have no idea where one can fly to from there, but I know there is an airport there. If one flies into Belfast having been in any country in the world, or if one drives or gets a bus or train to Belfast having been in any country in the world, the Department will have no record whatsoever of one's movements. Any such passenger may be a non-resident in Ireland coming to Ireland on a holiday via Belfast, or an Irish person who does not fancy being unable to go to work on a Monday morning and instead decides to go on holidays via Belfast.

I am referring to people who are deliberately choosing to do that, which I presume Mr. Towey would discourage. That being said, I am sure there are people in the Border area who fly via Belfast. People from Belfast regularly fly from Dublin so I presume the opposite is equally the case.
