Wizz are back at Chopin permanently, in exchange for an 85%(!!) discount on fees and a marketing agreement with Polish State Airports (125,000 for a route) according to a respected Polish website related to aviation in the country.
It'll be interesting to see what happens next, considering recently Ryanair had made a complaint about PPL to the EU about Chopin Airport treating them unfairly when it comes to fees, as we all know, PPL and Ryanair have a history of disagreements and don't like each other.
