GDN and WAW remain but KTW and POZ were dropped as the massive influx of Eastern Europeans slowed down.
But really?? Is that not just Wizz Air's explanation for cancelling those routes? Reality is that airlines don't often cancel routes simply for the reason they give to the public, it's often something much more complex and internal than that. Also, why would only the Prestwick/Glasgow area be effected by basically a fall in demand whilst every other European city, plus the other three UK airports Wizz Air fly from have managed to sustain and build further connections with Wizz Air.
