From my experience with OS *G gives nothing in terms of seats; in fact, the check-in agent could not even see my status (through TK) and no status info was printed on my BP. I found this weird as with OW it works perfectly well - airlines recognize each other's status without the actual card...
I have 2 bookings with LH in economy in Europe and I can't select any seats. Call-centre agents also claim that they can't see my status.
I also assume that no lounge access will be allowed without the actual card?

Is it a TK thing or what shold I do to ensure that LH sees my *G status at least for seat selection?
Thanks.
