AL SYD you are absolutely right : this is clearly mentioned on 'Flyzed' site (and after to day's check) following airlines appear : AY - DE - KF - LH - OS - SK - TG - WF.: apparently, TG is included.
This is as appears reaching FLYZED through AF staff listing internal site.
Therefore I am tempted to believe that there is something wrong in the connection between Flyzed and TG reservations site.
