Thanks, Tallinn is now Rheinthalflug destination (Lauda used to fly here and was know for great service).

I did meanwhile some research myself and found most helpful Star Alliance Timetable http://st.flightlookup.com/StarDownload/pos.html according to what PRN (pristina), Sofia (SOF), Larnaca (LCA), Palma de Mallorca (PMI), Timisora (TSR), Riga (RIX), Lyon (LYS), Geneva (GVA) And Zurich (ZRH) are Lauda destinations.
