Stephen, without wanting to disillusion you, I'm affraid that you will NOT be allowed to change to LOT, and that the information you were give on the phone was wrong (it's a known fact that most FFP phone agents know less about their programme rules than FTers do). The Qualiflyer website is very explicit about the rules governing the change from QG to the post-2002 programmes. If you were not invited by LOT in the first place, then there is no (official) chance to switch to LOT. There may be rare exceptions, but I suppose these would only be given to Polish residents. You may however try to push them, or ask very politely, or just play naive, and it may work for you. I was considering to do exactly that myself, because until yesterday (the deadline for switching between the LX, SN and TP programmes) absolutely no information has been officially provided on future award levels, partner airlines, etc. As I have stated on these boards before, I find this lack of communication disappointing and scandalous. When the rumors were disclosed here yesterday that SN would fully partner up with BA, IB and AY, I briefly considered changing to SN Privilege. But LX serves most of the destinations I require and I regularly fly between Germany and Switzerland both private and on business, so LX should serve me well. But my loyalties will be more spread than before (used to be almost exclusively LH, OS and LX). I will either build up some mileage in SN Privilege as well, or wait for the announced programme changes in the BA Executive Club and pile up miles their.
Anyway, good luck with your attempt at LOT and M&M - still my favourite programme.
