Felis, as I understand it, transferring Qualiflyer points to LH M&M was never an option EXCEPT for LOT-originating Qualiflyer members. If this applies to you, go for it, though I imagine you would have heard from them by now.
Otherwise. it looks as though you will have to choose between LX, SN and TP - you're beyond the choose by date, but I guess Qualiflyer will help.
