WZZ (or their ultimate owners) are really going for it aren’t they. I know a lot of these will be replacements but at some point there will become saturation unless they diversify into other markets (India, as has been suggested above).
I slightly fear for the likes of EZY post pandemic up against this power and aggression from the East, who tried to buy them out recently. EZY being by far the best (in my opinion) LCC in Europe. For the employees involved, the race to the bottom will continue even more so.
