Who knows?
I'll tell you who knows what in Wizz Air: the CEO, the Executive Vice President, the CFO (definitely) and maybe the Commercial Director.
Failing that, absolutely no-one in Wizz Air has access to the up to date figures with any certainty - at least that is how it has always been.
I don't think TBSC is any of the above people. They aren't on pprune.
The reality is this: Wizz Air is well run and VERY low cost. It has been around a good while, and I reckon it will be for some time to come.
Undoubtedly, the make money in Summer and lose it in Winter. How much, and if it balances is anyone's guess (except those named above - because they know).
One thing is for sure though IMHO. They won't reach 120 airframes - ever. The market isn't there any more, and I doubt it is returning any time soon.
