A short look around BHD or BFS car park, in particular BFS in summer will tell you just how many people are driving from Ireland to use what are often now cheaper flights. It's horses for courses, there's people I talk to think DUB is the only airport to get to all sorts of places, there's people who don't believe me when I say Norwegian fly transatlantic from BFS, and recently in a meeting with a company manager from Dublin I was informed many Dubliners use BFS if it's cheap enough - and that I think is the key. How many weird and wonderful off the beaten track airports have FR turned into household names, some with literally military style facilities.
