There is a big thread on one of the travel blogs about the YYZ to MUC flight:

All the United folks are going crazy as this is a way they can book LH F before their huge devaluation comes into play. It appears that UA MP members are able to see and book the flights, but none of the other Star Alliance partners can book 'em.

I called AE and even escalated to a supervisor but it didn't help. He just said he would report the issue to IT.

Too bad. Was going to book F for Oktoberfest. MUC is one of my favourite cities, the airport is fantastic (except for the transportation to/from), and new First is just awesome.
