Oh yes, Wizzair has just made some changes to its callsings, and now all of them, at least those to/from EPKT, have a pattern of WZZ4??. Anyway, it's better than those that they have used during April - i.e. WZZ4455. Wizzair FoFoFaFa
or worse, there is permutation to this callsign WZZ445S and WZZ445G
and my eyesight is not as good as it used to be
