Regarding Wizz, it's disappointing.
I was hopeful to try them out of DSA on a few routes this winter but the constant delays, strange fare structure, and employment practices (other threads) makes them look like an inept poundshop Ryanair.
I think they've damaged their presence with the local market as they could be deemed seriously unreliable whilst every other airline in similar markets (FR, EZY, LS) is operating a sustained schedule.
I could book with Wizz out of DSA and risk having my flights pushed back ad nauseum (which would cost me substantially more money having to rebook with other airlines) or book initially with a reliable competitor out of LBA/MAN/EMA.
