I don't think Luton is the focus of what Wizz are doing
Blue Air currently fly from Bacau to:
Bergamo, Brussels, Dublin, Luton, Rome FCO and Turin
Wizz will fly from Bacau to:
Bergamo, Brussels-Charleroi, Luton, Rome FCO, Turin and 7 other cities
Wizz don't fly to Dublin, not even from Budapest
Wizz seem to be trying to take over from Blue Air in Bacau
