Wizz (to me at least) is a big mystery financially, they've always claimed that they made a profit and made a bold claim during the time that Sky Europe went bust that they were profitable for several years although 2-3 years ago I vaguely remember reading a few articles saying they had never made a profit and last year also an article saying they were tipped as one of the most likely airlines to go bust.
I don't think they've ever commented on their finances like Ryanair would do, I'm not even sure if they need to publish them in Hungary like they would have to in most countries.
