Domestic routes only considered for expansion at the moment to keep their cost base low.
Next routes were going to be NQY-BOH-MAN and PLY-BOH-BFS but since Jet2 have come in on BOH-BFS, they are re-thinking their route structure.
So perhaps INTL routes are not that far off...
Air Southwest at Bournemouth would make perfect sense in terms of their name and LCC model.
