"BA is for British people,who include Scottish,Welsh and NI"
The above phrase does not even merit a reply

As for the size of the population I think Eire only has around 4 million but Aer Lingus manage to fly to places other than London.

Not sure of your definition of a sun route but maybe 3 or 4 routes from PIK could be called that but not the other 24
