Wizz dropping OSL / PRG / SVG from June.
They haven’t really had much luck with the Scandinavian routes since starting. I guess putting the A321 on some of the routes from the start was a tad over optimistic.
TOS finishes at the end of March- if it is seasonal I am not sure.
PRG/ VIE end up swopped over between Easy and Wizz so no actual loss of route.
