The Krakow route seems to have surpassed all expectations with load facotor in the 90s ...I would expect that Wizz may pick up even more of the Polish traffic as they would be better known at the Polish end.
There's definitely room for both Easyjet and Wizz. While Easyjet fly to Krakow a more touristic city, Wizz are flying to Katowice a larger city with a much greater catchment area.
We can also expect the Warsaw route to be a HUGE success
