There are unusual large LX availability these days - I was able to book 5 pax in J on LX87/LX86 (YUL-ZRH) for December. The Aeroplan agent I spoke to said it was very rare that 5 reward seats in J were available like that and mentioned that it wasn't possible to book LX through Aeroplan for like 4 months and that maybe this is why there is so much inventory.
Anyway I thought I would pass this info along in case it can be useful to someone.
