Yes, some people mentioned it last year although it seems to remain very rare, and it was clearly more than a 'cheap' business class ticket to upgrade (or at least than half a cheap Z or I return). Moreover, if I remember, it was reported that this was offered on flights which were oversold in Y and where conceivably people may have been op-up'ed instead. These two things make the offer different from NW (which also offers upgrade for a fee when the flght is oversold in Y, but at least for cheap) and from BA (which offers upgrade for cheap when the flight is quite empty in C). Personally, I was never offered the upgrade for a fee. AFAIK, AF never offers this opportunity.
