I've never flown with them but my friends did for a trip to Mexico once. Their outbound flight was delayed for a long time. One of the toilets on the plane didn't work. They didn't have a very good flight at all.
To be honest, while I'd have to think twice whether I would choose a flight with them, it's kind of disappointing to lose that option & competition.
