daz211...Not accounting for economic geography.
Primera staged a large event to coincide with their transatlantic launch plans in Cambridge clearly stating the "Cambridge Corridor" is very important in their planning.
Not to mention North & East London of course.
I might also query an overall public perception of Wizz..Yes well known @ LTN for multiple flights to "Eastern Europe" but not really perhaps a huge advantage over a new entrant into a "new" created market.
If WIZZ comes to fruition they clearly regard the Primera concept as a valid business model to emulate.
