Given the relative population of the Southeast.
Some time ago, there was an interesting submission in Wisconsin as follows :

I suspect Edinburgh would be a flight of fancy. Getting 50 people all from the South East, all wanting to go to Edinburgh on a particular day.........and do so over a longer period. I don't see this. High population density routes with economic ties to the Southeast. So London is the most obvious. And after that maybe a Birmingham and Manchester. There is perhaps an arguement for a Ryanair or Aer Lingus jet service to Malaga or Faro during the summer season.
Freight - now that is an interesting one. How does freight work? Is there enough coming out of or heading into the Southeast?
Cheers.
