Precisely what I mentioned a few pages ago. You aren't really comparing apples to apples by comparing Wizz air and BA/AF/KLM/EZY/LS. The scene in most countries where Wizz air have their bases mostly comprises weak and unattractive to work for legacy carriers and lots of ACMI companies featuring no fixed base or roster, unimpressive pay, ancient aircraft (where else would you see a living MD82 or a non-EFIS B737-300 these days?) and zero job stability as the majority of those places are heavily reliant upon someone else needing cheap extra capacity for a while. So, for most locals, Wizz air and Buzz are a totally different dimension, as compared to anything else available locally. For sure, it becomes another matter if you're willing to commute X weeks ON and Y weeks OFF to Asia - but not everyone is up for that for many reasons.
As for contracts, did you mention Confair? Is this scheme back after the April redundancies then?
