I would like to see ALL airports prosper.
You say Carlisle people are poorly served,but I've been checking distances.
Carlisle-Newcastle(nearest airport with flights?) is 56.3 miles.
Blairgowrie(where I live)------Edinburgh(nearest airport) is 55.9 miles
Blairgowrie----Aberdeen (2nd nearest? possibly Glasgow nearer--didn't check that!) is 75.2 miles.
So not any worse than me!
edited to say Glasgow is 87.7 miles from me.
