I think you may be thinking of Sitia on Crete that had 1/2 charter(s) a week from OSL/CPH (until EZY announced it for S24)? Either that or possibly Kithira which gets the odd charter from Prague (also Smartwings) - though I mistakenly thought this was a Dutch charter at one point. Either that, or as previously mentioned above Paros on Smartwings - which went back to PRG via JTR) Paros is now also served on charters by Avanti Air from Graz and Klagenfurt each once weekly with the PAS-Austria flights operating via ATH for refuel as from what I can gather there is no fuelling possible at PAS.
